Lathing under a metal tile. Installation features. Technical characteristics of Monterrey and Supermonterrey metal tiles: length and width, lathing pitch and special installation technology Step of metal roofing sheathing

Roofing is designed not only to protect the structure as much as possible from the effects of atmospheric factors, but also to give it an aesthetic appearance. This task is well coped with, which appeared in the 80s. metal tile.

Metal tile as a roofing material

metal tile represents the thin metal sheets profiled under the form of the laid ceramic tile covered with a protective layer. Metal used - stainless steel, copper or aluminium.

Various coatings give the material the necessary decorative coloring and provide a high degree corrosion and UV resistance. Life time quality products with care - up to 50 years for steel products, up to 100 years or more for copper and aluminum.

The choice of metal tiles for the roof- a solution capable of acceptable price to ensure high quality, presentable appearance and durability of the roof, without burdening the builder with complex installation procedures and the purchase of expensive tools.

It is impossible not to mention the low weight of such a coating, 5-10 times less than slate and ceramic counterparts. This allows you to lighten the roof as much as possible and save when building a house.

Disadvantages of metal roofing:

due to the shape metal tiles are not used for roofs with a slope angle of less than 14 degrees;
lack of heat-insulating and sound-proofing properties forced to install an additional insulating layer on the crate;
corrosion of steel in places of cuts and fasteners, with poor-quality fixing material, the roof will quickly begin to leak;
condensation during cold weather, additional waterproofing is required;
thin material thickness(0.3 - 0.5 mm) does not allow to achieve high strength, especially from copper and aluminum tiles. This increases the risk of damage to the material during installation and limits the ability, if necessary, to move along it;
installation complexity and material consumption increase much faster than the complexity of the roof shape.

Classification of metal tiles

The metal tile is divided according to

1. Material:

copper tiles- very durable and only improves its appearance with age, is extremely rarely used due to the high cost and complexity of installation;
aluminum tile- Durable, lightweight, but expensive. It is supplied with a coating resistant to physical stress, does not have a wide choice of shades of color, which is why it is rarely used;
steel tile- the cheapest, most durable and common option, subject to corrosion, therefore it is supplied with a two-layer coating - galvanized and polymer.

2. Profile geometry:

"Monterrey"- the most popular profile with an asymmetric wave, imitating clay tiles, has many modifications (Sierra, Spanish Sierra, M28 and others), experimenting with the length, height and shape of the wave;
"Banga"- a popular profile with a symmetrical wave, imitating ceramic tiles, also has many modifications;
"Cascade"- trapezoidal profile, more convenient for covering complex-shaped roofs;
"Shanghai"- a profile with a pattern of a typical East Asian roof;
"Andalusia"- in assembled resembles the “Banga” profile, but has a completely different mounting technology. Hidden fasteners and special locks on the sheets increase moisture resistance and increase durability, however, the need for special equipment and the price still make such tiles unpopular.

3. Type and location of polymer protective coating:

bilateral or unilateral- a product with a double-sided coating is more resistant to corrosion;
without cover– suitable only for copper tiles;
Pural – quality coating from polyurethane with polyamide, average price, service life of 30 years, provides long-term color retention, mechanical strength, resistance to corrosion, UV rays, high and low temperatures;
PE– the most popular cheap polyester coating, service life of 5 to 10 years, provides resistance to corrosion and high temperatures, does not like severe frosts and acid rains. Matte modification PE increased thickness provides a service life of up to 15 years;
purex– polyurethane-polyester coating invented in Finland, service life up to 50 years, average price, pleasant semi-matte color, high performance;
Pur- polyurethane coating, found in combination with others, depending on the manufacturer, usually ensures the durability of the roof for at least 15 years;
PVC (plastisol)– a coating of polyvinyl chloride and plasticizers, has an above average price and provides excellent mechanical strength, but loses it by severe frost, fades in the sun and floats at temperatures above 60 degrees.
PVDF– a coating of polyvinylidene fluoride and acrylic, rarely used due to the high price, has characteristics similar to PURAL and special shade color, giving the roof a representative look.

Some manufacturers are experimenting with roofing material, making metal tiles from unusual materials, giving it unusual shapes or covering it with an unusual coating. Such tiles cost an order of magnitude of the above types, but will help give the house a wealthy owner unique look.

Choosing a metal tile

How to make the right choice? When buying a metal tile, the determining factors are the budget, the design preferences of the home owner and the climatic conditions. When building with your own hands, it is necessary to take into account the complexity of installation.

When buying steel products, it is important to consider the following factors:

a sheet thinner than 0.45 mm is not strong enough, thicker than 0.6 mm creates difficulties during installation;
tiles with a declared service life of more than 15 years must have a zinc content of 275 or more g per square meter;
a large wave height increases the rigidity of the roof, but is also more expensive;
with the same type of polymer coating, its thickness almost linearly increases the service life of the tile.

Having chosen the color and shape of the profile for the future roof, it remains to choose a coating suitable for your climate and wallet.

For rainy and windy seaside climates with small annual fluctuations in light and temperature, plastisol is most suitable, excellent protection against rain, hail and flying branches, but collapsing at high temperatures.

For hot and dry environments very attractive matte polyester or PVDF.

In a temperate continental climate with its severe frosts in winter and heat in summer, the most protected of universal solutions- polyurethane, Pural, Purex.

In an effort to save polyester is suitable for quality for any conditions, which has an average protection against all threats.

Absolutely not required to buy branded Finnish or British products, the domestic manufacturer also learned how to make high-quality coatings. But still, before buying, you should find out how the manufacturer has proven itself, and whether the thickness and composition of the coating meet Finnish standards.

Before the final choice it is worth making sure that the sheets are tight in a stack of tiles, if they lie loosely, the joints of the sheets after installation will be visible.

Lathing device

crate- the structural part of the roof, installed on the rafters, and serving as the basis for fixing the roofing material.

Depending on the requirements for thermal and sound insulation and the need to save lumber, use one of four types of crates:

The most simple and not very economical- solid wood flooring on the rafters parallel to the ridge with small gaps for ventilation, the waterproofing lies on top of the flooring and the tiles are attached.
The most economical- waterproofing lies on the rafters. On the rafters, perpendicular to them and parallel to the ridge, there is a crate board with a step equal to the wavelength of the tile. In this embodiment, steel profiles are often used instead of boards.
The most popular double-layer construction of the counter-batten- beams stuffed on top of each rafter on a pre-laid waterproofing, and crates with a step.
Three layer option: The 1st layer is a solid flooring and waterproofing on it, the 2nd counter-lattice is made of timber nailed diagonally to the flooring, and the 3rd is a crate board with a step, nailed onto the counter-lattice.

Three features of the extreme row of the crate

Through the cornice board, waterproofing descends into the drain. If the design of the drain does not provide for a special waterproofing surface, then outer corner the cornice strip is cut at an angle of 30 degrees to improve the outflow of water, and the waterproofing was not damaged by a sharp edge.
1st bar from the bottom- the most important in terms of the absence of deformations on the roof. The location of the remaining bars is measured from it, and a sheet of tiles begins to be attached from it. Therefore, it is very important to set it correctly, taking into account the necessary horizontal position, the gap from the wall to the edge of the eaves, the design of the drain.
1st bar from the bottom it is taken somewhat thicker than the others to compensate for its location not at the lowest point of the wave of the metal tile (the lowest point hangs over the drain).

It is necessary to choose the design of the crate before installing the truss system, so that it is less work for building rafters if necessary.
Choose and buy a metal tile and the auxiliary parts attached to it - before installing the crate, in order to take into account the nuances in advance and not overspend the material.
If there is not enough lumber length, it can be spliced by installing a joint on one of the rafters. At the same time, it is undesirable to install all joints on the same rafter; do this with each rafter in turn.
If there is a need to drive 2 nails into a beam or board at a short distance from each other - you do not need to do this in one longitudinal fiber, even a thick beam can crack from this. Move diagonally at least a little.

Possible defects of the lathing under the metal tile

The presence of a defect in the crate can lead to

visual deformation of the entire roof,
installation difficulties due to misalignment of sheets,
difficulties in the installation of auxiliary and decorative elements (gutter, facade, snow retainers),
increased roof noise,
impossibility of installation (with a completely wrong step).

Lathing step and its installation

Lathing step is selected based on the wavelength of the metal tile so that the crate board is in contact along the entire length of the sheet with the lower parts of the waves into which the screws are screwed.

Distance between first and second the lower lath of the crate is less than a step by a third of the diameter of the drain. For example, for tiles with a wavelength of 40 cm and a drain with a diameter of 15 cm, the 2nd plank will be at a distance of 35 cm from the first.

Installation of battens carried out using self-tapping screws or nails, 60 - 100 mm long, depending on the thickness of the material.

The crate is nailed for each bar of a counter-lattice or rafters. In the case of using boards 25x100 or 32x100, fastening at each intersection is done with two nails in order to avoid deformation of the roof when the material dries out.

Lumber selection

Wood is applied to the crate conifers. Before installation, lumber is necessarily processed by a fire and biological protection complex.

The dimensions of lumber used in the crate:

edged board 32x100 mm - used with a rafter pitch of 90 cm and a tile thickness of 0.5 mm or more for a continuous crate or with a pitch;
edged board 25x100 mm - used with a rafter pitch of 60 cm and a tile thickness of less than 0.5 mm;
beam 40x60 mm or beam 50x50 mm - used for lathing if the rafter spacing is more than 1 m, for counter-latticing;
board 150x40 mm - for the ridge, for the cornice.

Instruments

To install the crate you will need:

For convenience, instead of marking, you can make or buy a special template for the crate step.

For the installation of metal tiles you will need:

screwdriver and roofing wood screws 35 mm;
scissors for metal or a saw with a disk for metal, a grinder - spoils the tiles;
roulette;
pencil;
soft brush for cleaning construction debris from the coating;
soft shoes for walking on already installed tiles.

The order of the device of the crate under the metal tile

We install a solid eaves board in special grooves on the rafters. Its recommended dimensions are 40 mm thick, the width is taken based on the design of the gutters. We fasten the drain to the outer edge with self-tapping screws.
Thermal insulation is installed according to the manufacturer's instructions.
A waterproofing membrane - a film - is stretched over the entire roof slope to be mounted along the rafters and the cornice board. It is temporarily stapled/nailed to each rafter with little slack. If necessary, connect several pieces of film with an overlap of 15 cm.
The membrane is fixed by installing a counter-lattice- stuffed on the rafters along the entire length of the strips with a thickness of 30 - 40 mm. The counter-lattice is fastened with self-tapping screws or nails of triple length - 90 - 120 mm.
Installed perpendicular to the counter batten 1st lower lath of the batten increased thickness at a distance of 2 cm from the lower end of the counter rails. It must be carefully leveled. Similarly, a crate of increased width is fastened near the ridge at a distance of 2 cm from the intersection of the counter-battens of two roof slopes.
2nd lath of the crate is installed taking into account the release of a sheet of tiles for 1/3 of the diameter of the drain.
Installation of the remaining strips with a step equal to the wavelength of the metal tile.
Waterproofing the 1st bottom bar from the roof. It is necessary to ensure that the gap between the eaves board, waterproofed with a drain, and the 1st lath of the crate is not blocked, this gap provides roof ventilation.

Depending on the type of drainage system used, necessary actions may be different, so it is necessary to carefully consider the design of the roof before starting work.

The device of the lathing at the eaves and at the ridge of the roof

The nailed counter-battens on the rafters converge above the roof ridge. At a distance of 2 cm from their connection (depending on the slope), crate strips 100 mm wide are nailed, regardless of the previous crate step. A gap of 2 cm provides the necessary ventilation in the roof.

The need for ventilation of the roof and the installation of a drain requires a special design of the crate at the eaves. The 1st batten should be a wave height thicker than the others, and at a closer distance from the 2nd, in order to direct water from the roof to the center of the drain.

The gutter itself is designed in such a way as to receive water not only from the roof, but also from the under-roof space. To do this, waterproofing is glued to the cornice board, through which all the condensate flows through the gap between the cornice board and the 1st plank directly into the drain.

Installation of metal tiles

In what order is the metal tile installed?

Fixing sheet metal

For most conventional types of tiles, the scheme is one self-tapping screw in each groove along the 1st lower lath of the crate, and then through 1 in a checkerboard pattern for all higher laths of the crate.

When arranging a roofing pie, you can’t do without a crate. But when installing it, there are many subtleties. What material to choose, with what step to install and how much sheathing will be required on the roof? These questions need to be addressed before installation work. Features of the roof will depend on the chosen coating. You can make a crate for a metal tile with your own hands.

The crate under the metal tile is a cut board, which is installed with a certain step for fastening the roofing sheets. And their thickness is determined in accordance with the angle of inclination of the slope, the pitch of the rafter legs, and the height of the snow cover.

Coniferous trees can be used as material. Pine boards are the most common.

The scheme of the flooring of the crate must be selected before the start of installation work. Its type will depend on various parameters:

If there is a heated under-roof space, in addition to waterproofing, laying a counter-lattice will be required, which will create a ventilation gap. Such an event will ensure the removal of water vapor from the insulation.
The counter rail is not needed when installing the crate on cold roof. In this case, waterproofing is used in the form of a film laid on the rafters, which will provide additional protection of the under-roof space from snow and rain, which can get under the joints of the metal tile, ridge or cornice overhang under the influence of a strong wind.

The step of the crate will depend on the type of metal tile. Various manufacturers offer different cell sizes. These recommendations should be indicated in the instructions for the purchased roofing material.

So, for example, for a Monterrey metal tile, a crate with a step of 35 cm is required, and for Maxi - 40 cm.

The crate must be installed without violating the required step. Otherwise, errors can lead to problematic installation of roofing.

The process of installing the crate under the metal tile must be carried out strictly in certain weather. Should be dry and windless. This will ensure the safety of work at height, as well as eliminate the need for additional protection lumber from getting wet.

For work, you can also use moisture resistant plywood and OSB boards. Such a crate will create additional strength and give reliability to the roofing pie. The same effect can be achieved by installing a continuous crate of edged boards. But it should be noted that this significantly increases the consumption of material and the weight of the roofing cake.

Material selection

It is better not to save on the material of the crate, which is planned to be laid under the metal tile. As a flooring for such a roofing, only an edged board is suitable, which differs high quality and good drying.

Selection options:

The first and, perhaps, the most important requirement relates to the thickness of the crate. The best choice would be a value of 32 mm, but it is also allowed to use edged boards of at least 25 mm. It is best to independently calibrate the spread of boards in thickness, which should not be more than 2-3 mm, before purchasing the material. in one batch.
If the variation in thickness exceeds the required value, then the use of such boards will affect the formation of inconsistencies in the sheathing on the rafters. And the laying of metal tiles will be uneven, the risk of wave formation is high.
A suitable board width is from 10 to 15 cm.
Allowed different length sheathing boards, but it is more convenient to use the corresponding step of the rafter legs. In this way, waste generation can be minimized.
A planed board will cost more and is not at all necessary for work. The minimum deviations in thickness will have edged unplaned boards, sawn on a good band sawmill.
Before installation, the crate is treated twice with a flame retardant and an antiseptic to prevent fire and decay.

The most suitable thickness of the boards for the sheathing will depend on the step with which the rafter legs are installed. Accordingly, the larger it is, the thicker the boards will be required. For example, with a rafter pitch of 90 cm, a crate with a thickness of at least 32 mm is used. And for a step of 60 cm, 25 mm boards are suitable.

Features of installation work

For example, we will consider mounting sheathing boards on a roof with insulation, because this is the most difficult option:

Before laying the flooring, some preparatory installation work must be carried out. Waterproofing is placed under the metal tile coating, and it must be fixed with a stapler to the rafter legs. The anti-condensation film is overlapped. Work is carried out by moving from the bottom up the roof. In this case, a suitable overlap width will be a value of at least ten centimeters.
Next, we proceed to stuffing the counter rail. She has another name that reflects the purpose - the ventilation rail. For this, a wooden edged beam with a section of 32x50 mm is suitable. You can also use boards with parameters 32x100mm.
The counter rail must be laid, stepping back from the overhang from 15 to 20 cm, and leave the place where the first crate board will be fastened. The starting board must be selected with a thickness corresponding to the sum of the thicknesses of the batten and the counter rail.
In the case of installing the first crate on the counter rail, its thickness should exceed the ordinary elements by 10-15 cm. This will avoid the formation of a hanging protrusion on the edge of the overhang.
Proper installation of the starter board will require special attention during installation. It must be nailed to the end of the rafter leg, positioning in a straight line. Do this throughout the cornice overhang. Next, with the help of screws, you will need to fasten a vertical board, which is also called a frontal board, and cornice plank from metal.
The gutter is fastened to the frontal board.
The first sheet of a metal-tiled roof is laid in such a way as to provide a protrusion of 3-4 cm beyond the edge of the cornice strip. This will ensure that snow and rain directly enter the gutter without the possibility of flowing into the under-roof space.
The most difficult thing is to properly arrange the overhang. Further fastening of ordinary boards of the crate is carried out using self-tapping screws or nails to the surface of the base, parallel to the starting board.
With any option for fastening the boards of the crate, bulging should not be allowed. fasteners. And their placement should be in the center of the board. When working with self-tapping screws, it is necessary to correctly tighten the gaskets.
In order not to be mistaken with the distance of the crate step and to simplify the work on constant measurement, you can use templates. For this, two slats of the appropriate length are suitable. They need to be applied to the bottom board, and on the upper part it will be possible to align the next board of the crate.
When working with the laying of metal tiles on the ridge or pediment sheathing, it may be difficult to see the fastener points. The sheets will cover the flooring. If the step of the boards of the crate deviates even by a seemingly insignificant couple of centimeters, you can simply miss the placement of the fasteners. The result is a defect in the form of a through hole to the roofing.
Another difficult moment in fastening the boards of the crate is ridge part. It is necessary to take into account, in addition to the main fastening of the metal tile sheet, the installation of a special profile that will cover the joint along the entire length. In order to ensure such an installation, floor boards of increased width are used. Let's say another option is to install two narrow purlins end-to-end.

In the presence of additional elements on the roof, for example, snow retainers or stairs, reinforcement of the crate will be required. This can be done by installing additional support boards.

Compliance with the following important rules guarantees you the correct installation of the crate:

In the place where the crate adjoins the ridge, pipe, skylights or valleys, its step is reduced to a maximum of one centimeter. For these places it is more rational to use a solid crate.
Gutters, as a rule, are mounted on brackets, which must be installed before the installation of metal tiles begins. The same swings the eaves plank.
An anti-condensation film will help protect the insulation from moisture. It is laid without tension, and the minimum sagging is allowed at one to two centimeters.
To compensate for linear expansion with a constant change in air humidity, the crate of sheet material is made with a gap of 3-5 mm. It is also necessary to shift the ordinary sheets relative to the first one by a distance equal to half the width. This will increase the strength of the rafter system.

What is the step of the crate for the Monterrey metal tile? Lathing under the metal tile monterrey scheme

Lathing under the Monterrey metal tile - a visual diagram

January 30, 2017

The most versatile roofing material produced in recent years is considered to be a metal tile. This material will be in harmony with brickwork and wooden logs. It will give an aesthetic appearance to small country houses and huge villas, preserving the traditions of previous generations.

The most common type of roofing is the Monterrey metal tile. It differs from other brands in sheet relief. Therefore, for long-term use of the material, it is necessary to correctly install the crate under the Monterrey metal tile, a diagram of which can be found on the Internet.

Features of Monterrey metal tile

The metal tile is a metal sheet with a relief pattern imitating an old ceramic tile. Longitudinal and transverse relief gives the sheet rigidity. Metallic profile Monterrey has the following geometric parameters:

wave height - up to 25 mm;
step length on average 350 mm;
sheet thickness - up to 0.9 mm, sheets with a thickness of 0.4-0.5 mm are more often used. Width and length - 1180x4000 mm.

Having such parameters, the profiled sheet does not differ in particular strength, therefore it is the crate installed according to certain rules, promotes durable use of a roofing covering.

The popularity of the metal tiles of this brand is also due to the fact that it has a large range color solutions. Polyester coating ensures the safety and integrity of the metal sheet up to 30 years, appearance- up to 10 years, which is indicated in the manufacturer's warranty documents.

In addition to the above parameters, the material has the following characteristics:

fireproof;
ecologicaly clean;
impact resistant environment- rain, frost, sun;
light weight, does not require hardening of truss beams;
ease of installation, repair and replacement of worn or damaged sheets;
the possibility of using more than 14 multi-level roofs as a roof for houses with any roof slope.

Roof installation sequence

The truss system of the house is made of well-dried beams, without cracks, traces of decay and other damage. This system must be installed in compliance with all standards, namely, the angles of the roof bevels are the same from different sides (checked with an inclinometer) and all horizontals. In case of any deviations, it is necessary to finalize the design and correct all the shortcomings, otherwise the metal tile will not be able to be laid with high quality, which will lead to its rapid wear.

Insulation is laid between the rafters. It will allow you to keep warm in the winter and will not give the opportunity to heat up the air in the attic in the summer.

To eliminate the effect of warm air rising from the lower floors on thermal insulation material and wooden structures the roof is being laid vapor barrier material. It keeps the load-bearing structures from getting moisture from the room.

With outer side roofs, a water-repellent material (film, roofing material) is laid on the insulation to protect against precipitation, wind blowing and other natural phenomena.

Before starting work on the crate under the Monterrey metal tile, it is necessary to draw up its scheme. The crate serves directly to fix the profiled sheet on the roof. The quality and durability of the material that protects the home from bad weather depends on the correctness of its installation. The step of the crate for the Monterrey metal tile should correspond to the length of the step of the metal sheet, namely, with a step of 350 mm - the step of the crate is 35 cm.

The counter grille is installed between the crate and the hydrobarrier to provide ventilation and prevent the formation of fungus.

The rafters, the counter-lattice and the crate must be made of quality wood(pine is more often used - it satisfies all the requirements, provided that the boards are properly prepared). The surface of the boards must be smooth without defects, humidity readings - no more than 20%. The boards are treated with special substances that are harmless to humans to repel insects and protect against the negative effects of the environment.

Lathing installation

The board for the crate should be of the following dimensions:

width - 100 mm;
thickness - 30 mm, for the lower row of the crate (near the eaves) - 45 mm.

Work on the roof lathing starts from the bottom and continues to the very top. Between the first and second row of boards there should be a distance of 30 mm, all subsequent rows at a distance of a step of a metal tile sheet. In places near the pipe, roof window or valleys, the crate is made continuous. Solid sheathing can be done over the entire roof, but this is not economically feasible.

Sheets of metal tiles are attached to the crate using self-tapping screws with a rubber washer. Protective film removed from the profiled sheet immediately before installation. Sheets must be laid overlapping each other.

Outcome

The installation of the crate and the installation of the Monterrey metal tile can be carried out independently, but you must understand all the responsibility. The preservation of the appearance of the house for a long time and the ability to forget about any problems with the roof depend on the correct installation of the roof layers.

Do-it-yourself Monterrey metal tile installation

Roofing works using metal tiles have their own subtleties. In order for the roof to serve for a long time and reliably, you need to familiarize yourself with the technology of each process in advance and carefully adhere to it. If you follow the instructions, installing a Monterrey metal tile with your own hands will not cause any difficulties even for a novice master. The roofing process consists of two main stages - the preparation of the base and the laying of the coating.

Preparing for installation

It is necessary to prepare very thoroughly for laying the finish coating. First, they check the shape of the roof slopes, because if the truss system has distortions, the roof will not hold firmly.

The check is carried out as follows: the width and length of the slope are measured with a tape measure on each side of the building, the irregularities are removed with the help of additional elements. Be sure to check the level of the location of the ridge and the cornice relative to the horizontal to avoid deflections of the roof. When replacing the coating, the truss system is checked in the same way.

If the slopes correspond to the norm, proceed to the next stage - laying waterproofing. For waterproofing, roofing material and a special microperforated film are best suited. The hydrobarrier is laid horizontally, starting from the eaves; strips of material overlap by 15-25 cm. It is impossible to stretch the material: the film should sag between the rafters by 1.5-2 cm, but at the same time not touch the insulation located under the crate.

The next step is the installation of a counter-lattice, which should provide ventilation between the metal tile and waterproofing film. If the roofing is fixed close to the waterproofing, the protruding condensate will accumulate inside the structure, which will lead to decay and destruction of the rafters.

To make a counter-lattice you will need:

dry dense timber with a section of 30x50 mm;
galvanized nails;
a hammer;
hacksaw or jigsaw;
roulette;
antiseptic primer.

If the slopes have a slope of less than 30 degrees or a roof of complex shape, the bars should be chosen with a larger section, for example, 50x50 mm.

The quality of wood plays an important role, therefore, before installation, you should make sure that the material is well dried, has no voids, and is not curved. It is worth paying attention to the color of the bars: gray sections or dark spots on the surface indicate improper storage of lumber, which reduces its service life.

The length of the beam should be approximately 130-140 cm; to make the design look neat, the bars are cut into equal segments before installation. Then the tree is treated with an antiseptic and dried. Such treatment prolongs the operation of the structure, prevents the development of fungi, and repels insects. After the timber has dried, you can proceed with the installation.

Using galvanized nails, the beams are nailed to the rafters over waterproofing membrane. For Monterrey metal tiles, the step of the counter-lattice is 30 cm; start fastening from the eaves. The arrangement of the roof ridge requires the intersection of the bars from different sides of the slope at one point, so they are cut down at a certain angle. To correctly calculate this angle, you need to take measurements with a special rail with a frame and a pendulum. This tool is called an inclinometer and is used in the arrangement truss systems.

For gable roof the counter-lattice is carried out the same way on both sides with a uniform step of 30 cm. If the configuration is more complex and the slopes form internal corners at the joints, the bars are mounted differently. Inner corner roofing system is called a valley; this area experiences more loads than the rest of the roof, as rain and melt water flows down it, more snow accumulates, and the sun heats up more. To avoid leaks or collapse, the installation of the valley must be carried out strictly according to the technology.

The counter-lattice is nailed to the longitudinal bars of the valley in increments of no more than 10 cm; it is also impossible to fasten the beam close to the flooring of the valley - this will impair ventilation and make it difficult to remove condensate.

An important point: when hammering nails, holes are formed in waterproofing film, which violates its integrity. To avoid the penetration of moisture in the valleys, the consumption of nails per square meter should not exceed 10 pieces.

Manufacturing of crates

The roofing must be attached to the batten, so the next step is to clad the counter batten with boards. They take boards 100 mm wide and 30 mm thick, and for attaching the bottom row, the thickness must be at least 45 mm. After trimming, the material is treated with an antiseptic and dried.

Do not use wet boards, as after drying they can be deformed. The first board is laid from the eaves, the next one is fixed 30 cm higher. All subsequent nails are nailed in increments corresponding to the distance between the waves of the metal tile. For example, if Monterrey Maxi or Lux metal tiles are used, the distance between the boards is 40 cm, for Monterrey Standard the lathing pitch is 35 cm. In the valleys and at the exit of the chimney pipes, the lathing is mounted solid.

Now you need to fix in inside corners ready-made valleys, laying them with an overlap of 10 cm, and around the chimneys, internal aprons on the junction strips. The last to fix the eaves and end strips with a protrusion of 4 cm. To do this, a board is nailed to the ends of the rafters and the end strips are attached to it, overlapping them by 7-10 cm. On this preparatory stage considered complete, you can proceed to the sheathing of the roof.

To install the Monterrey metal tile, you will need:

sheets of metal;
metal scissors;
hammer and screwdriver;
flat rail or rule;
marker.

It is impossible to cut a metal tile with a grinder, since the abrasive layer destroys the protective coating, and the material corrodes.

Sheets are laid vertically, starting from the eaves. For installation, it is recommended to use sheets whose length is not more than 4 m. If you take short sheets, during installation, many butt joints are formed, and the reliability of the coating will be lower; mount very big chunks The material is hard and uncomfortable.

Horizontal direction when laying metal tiles of great importance does not have. With left-sided fastening, adjacent sheets must be placed under the previous row by 15 cm; with right-sided laying, the edges of the next sheet are mounted on top of those fixed at the same distance. The protective film must be removed immediately before the installation of the metal tile, it will be difficult to do this after the installation is completed.

The first sheet is laid on the lower edge of the crate so that it protrudes 5 cm down, then it is carefully leveled and fixed with just one self-tapping screw at the top. Next, the next sheet is overlapped on top, leveled and screwed to the bottom. It is not necessary to screw the coating to the crate yet. Having fixed another 1 or 2 sheets in a similar way, the resulting vertical block is aligned with the eaves and end strips and then screwed to the crate. Self-tapping screws should be located in deflections through one wave in a checkerboard pattern; be sure to use self-tapping screws with special rubber washers to fix the coating. 8 screws are required per square meter of metal roofing.

In places where the roofing adjoins vertical surfaces, it is necessary to use special strips, and an external apron is additionally installed around the chimney. After fixing the last sheet on the roof, install snow holders and accessories for roof ladders. If there are open sections, it is recommended to paint over them with any suitable paint.

Lathing step for metal tiles, description of technology, schemes

The choice of the pitch of the crate for the metal tile is the main rule for the installation of this material; if it is violated, the reliability of fixing the roof and its integrity decreases. Used as a carrier wooden planks with a thickness of 25 mm or more, the technology of their stuffing is considered difficult, if you doubt your experience, this stage is best entrusted to professionals. When performing work on your own, calculating the step and drawing up a diagram helps to eliminate errors. Manufacturers' recommendations are taken into account without fail, recognized brands ( grand line, Monterrey, Ruukki, Metal Profile, MeraSystem) indicate the exact dimensions of the profile and the requirements for the frame and additional elements.

Roof construction, purpose of the lathing

The standard scheme for cold and warm roofs is different, in the first case it includes load-bearing systems, flooring and a waterproofing layer placed under it. A ventilation gap is provided between the metal tile and the film; rolled products are attached with a slight sag. A board for fixing profiled sheets is stuffed over a konroblattice with a height of no more than 2 cm. For all its advantages (simplicity and budget), this type of roof is rarely chosen, both because of high heat losses and because of the noisy tile during rain.

The pie scheme for the insulated type is more complex, it includes a vapor barrier with inside attic space, rafters and longitudinal girders holding insulating materials (mainly mineral wool), a waterproofing layer that does not prevent the removal of moisture from the inside, a frame and tiles, counter rails and aeration elements are installed in the right places. By analogy with the previous option, during the construction of such a roof, a ventilation gap is left between the coating and the remaining layers. accepted additional measures on the withdrawal of internal condensate, it should not accumulate in the insulation. The functions of the counter-lattice also remain unchanged - the slats fix the waterproofing film to the rafters.

The crate is a mandatory part carrier system, it provides ventilation of the interior space. With its correct location and addition of aeration elements, moisture does not accumulate on the waterproofing layer and does not condense on the metal tile. The edges of the film lead to the gutters.

Depending on the frequency of the location of the boards, two types of flooring are distinguished: solid and slatted. In the first case wooden bars stacked with a minimum gap between adjacent products, 10 mm is enough to create good conditions ventilation and minimizing the risk of fastening tiles to the void. The recommended board width with this method is 100 mm, the minimum thickness is 32, the beam section is 50 × 50. This option is considered costly, such a scheme is rarely chosen (when building flat roofs and using more soft materials for flooring or when arranging complex projects with an attic).

Lattice crate is considered classic, bearing capacity ordinary boards when located in right points enough to hold galvanized metal. The weight of 1 m2 of Grand Line and similar popular brands with a thickness in the range of 0.4-0.55 mm varies from 3.7 to 6 kg, respectively, the load is distributed evenly. Reinforcement is required only for separate sections: near chimneys, valleys, at junctions with skylights and other roof structures.

Material selection

Coniferous wood is best suited to create a supporting base, they are easy to process and have the required degree of rigidity and biological stability. From deciduous, it is definitely not recommended to use birch and similar fragile varieties. The crate under the metal tile is stuffed exclusively from edged boards with the same thickness and moisture content of not more than 20%, if necessary, specially dried. All wooden elements are treated with antiseptics and flame retardants before installation.

The cross section of the frame depends on the complexity of the roof configuration and the expected loads. Square and rectangular timber 50 × 50 and 40 × 60 is used only in case of too large a step of the rafter legs (from 1 m and above). A board with a section of 25x100 mm is considered standard, this size is most in demand, 32 × 100 is bought when arranging complex roofs or fixing tiles to a galvanized sheet. To nail the crate to the rafters, nails with a diameter of 3-3.5 mm and a length that is at least twice the thickness of the wood are used. It is not recommended to increase their size, this is fraught with the destruction of the boards. For each fastener section, you will need at least 2 pieces of nails, they are purchased with a small margin.

Pitch calculation, influence factors

The tile is characterized by clear requirements for the frame, an arbitrary step in this case is excluded. Its profile has non-uniform strength and rigidity, the direction of the sheet is unchanged. The maximum reliability of fasteners to the bearing base is achieved when it is located at the bottom of the wave, otherwise it will break out. The main factor determining the packing pitch is the wavelength. Additionally, the following are taken into account: the slope of the roof slope, the presence or absence of a drain (when installing it to the frontal board, the protrusion of the first line of the crate under the metal tile is shifted by 30 cm) and the type of profile.

When using rectangular varieties with capillary joints (for example, Cascade), the pitch of the boards varies from 60 to 90 cm. For species with high profile and Z-connections (Andalusia and its analogues), this value varies from 40 to 70 cm. The step of the crate for Monterrey and other types without additional locks depends on the distance between the transverse waves, the exact value is given in the table:

Module length (L) for most popular brands (Grand Line, Mera System, Metal Profile, Monterrey, Ruukki, Stynergy) varies from 300 to 400 mm. If it is necessary to obtain the value of the indent from the first plank to the middle of the second when covering the roof with sheets with a non-standard wave, a simple formula L-70mm is used, the subsequent step of the board under the metal tile coincides with the parameters of its profile. With this approach, it is easy to draw up a diagram of the location of all cross beams roofs. Regardless of the step on the ridge section, they are stacked solid.

Features of the crate stuffing technology

Work begins after laying the waterproofing layer of the cake, fixing it to the rafters with thin slats no more than 20 mm high and attaching brackets for gutters. For stuffing, processed and well-dried bars with verified dimensions are used, in the presence of a valley - cut at a certain angle. The first row is laid with special care, all subsequent slats are measured from it. To compensate for the profile difference, it should be 1-2 cm higher than the others; when using boards with a standard thickness, another plank is stuffed on top.

All subsequent transverse elements are located taking into account the selected step, future fasteners must coincide with the middle of the stuffed beam. In the areas of junction with the over-roof structures and valleys, a continuous crate is made or the width of the board is increased. The same applies to the ridge, bending of the metal tile on the upper section of the roof is unacceptable. For this purpose, 2 additional boards are placed on both sides with a gap of about 5 cm between them. In the future, they are also used to fasten the skate itself.

The installation of the roofing is started in 2-3 days, in order to eliminate the risk of displacement of the crate under the sheets of tiles, all elements must be settled. With a sufficient thickness of the boards (from 25 mm and above), the use of counter-rails and high-quality antiseptics, the supporting base will last a long time and there is no need for additional wrapping of the beams with a waterproofing film. To important requirements technologies include ensuring the free removal of moisture and the overlap of membranes by 5 cm at least.

Monterrey metal tile installation: instructions

Roofing on a house under construction milestone. From right choice material and its quality flooring depends on the durability of the structure. It's good to contact the experts. For example, if Monterrey metal tiles are being installed on their own, then the instructions given by professionals will help to avoid many mistakes.

How to choose the right roofing

When deciding how to close the roof, the homeowner proceeds from a number of considerations.

The climatic conditions of the region in which the house is being built are taken into account.
Financial possibilities for the purchase of the necessary material are taken into account.
The parameters of thermal conductivity, sound insulation and durability of the future roof are considered.
The weight characteristics of the roofing are also important.
An important factor is the appearance of the roof.

Given all this, many developers give their preference to metal tiles, among which the Monterrey type occupies a worthy place. Monterrey metal tile is a metal roofing sheet that imitates a natural tile covering. In its production, galvanization is taken as the basis, which is coated with an anti-corrosion compound and primed. Then the bottom layer is varnished, and the outer, outer one is processed polymer coated.

There are several types of such coating for Monterrey and each gives this metal tile special properties. All this must be taken into account when choosing a material for your roof. In addition to good protective and mechanical properties, Monterrey is attractive due to its geometric dimensions. With a useful width of 1100 mm, its sheet can have a length of 500 mm to 9000 mm. The optimal length is 1000–4000 mm. It is convenient in terms of transportation and installation. The multi-layer protective coating and the presence of a polymer layer protect this metal tile from mechanical and chemical influences, as well as from ultraviolet radiation. All this gives Monterrey the ability long time keep original color and strength of the outer layer. Today it is important that similar material environmentally safe.

How to properly lay metal roofing

A step-by-step instruction will help a person who builds a house with his own hands to lay the roof correctly. At the same time, it must be understood that before the stage of installation of the metal tile, it is required to perform preparatory work on the device roof structure with sheathing and waterproofing.

When cutting Monterrey metal tiles with your own hands, you cannot use a grinder. In this case, the polymer and protective coating is damaged, which will lead to premature corrosion. Cutting with scissors is also not recommended, because the metal warps. Used for cutting special tool- cutting shears for metal.

We also recommend watching the following videos:

Lathing step for Monterrey metal tile, size |

We did not recommend installing metal tiles without certain skills in this article (for the reasons stated there). But is it possible to do the preparatory work with your own hands? This can be done based on preliminary calculations. Let's consider such questions as the pitch of the crate for the Monterrey metal tile, the size of the window, and others.

You should immediately watch a video about how the future owner of the house, in splendid isolation, mounts the frame on the roof of the building.

This is the general case. But we mentioned the Monterrey metal tile. Why? Because this type of roofing has gained well-deserved popularity among developers. The weight square meter of this building material does not exceed 5 kg. This, of course, attracts customers, reduces installation time and saves money on hiring outside labor.

We invite you to watch another production video roofing works with this type of coating, and then consider some of the nuances of installation work and step.

The size of the crate for metal tiles, step

Unfortunately, in the presented videos there is no clear mention of the geometric dimensions of the frame slats and there is no indication of what exactly the step of the crate should be. Let's correct these shortcomings, we will designate a step.

Notch for memory. The section of the details of the counter-lattice, on which the elements of the Monterrey batten are attached, must be at least 40 × 50 mm.

The installation scheme will be like this:

As you can see, nothing archaic.

Now more about the size of the bars of the crate under the Monterrey metal tile. The dimensions of bars 1 are desirable within the limits of 100 × 25, bars 2 - 100 × 35 (40) mm. As for the parameters a and b, they are as follows:

This is the usual step of the crate under the metal tile. Monterrey is no exception.

It should be added that if funds permit, it makes sense to do continuous construction crates. This will increase the cost of construction, but will prolong the life of the metal tile.

Instead of a bar, it is quite acceptable to use edged board size 32x100 (25x100) mm.

Important! Under the metal tile Monterrey Standard or Monterey Super, the step of the crate should be made equal to 350, and for Monterrey Lux (Maxi) it should be increased to 400 millimeters.

Well, do not forget about the overlap, which usually fits into the size of 150 millimeters. This is important to remember.

Lathing for metal tiles: step, installation, device

The crate under the metal tile is mounted in order to give strength to the entire roof structure, as well as to ensure natural ventilation under the roofing. It is a supporting frame on which sheets of metal are laid. Correctly performed calculation of the distance between the boards and their cross section directly affect not only the installation process, but also the subsequent operation of the entire roof. The crate for metal tiles should provide reliable retention of metal sheets during strong gusts of wind.

Frame arrangement example

The step of the crate under the metal tile must strictly correspond to the distance between the waves, depending on the type of this product.

Self-tapping screws, with which sheets of metal are attached to the elements of the crate, according to the technology, must fix the metal in the most rigid place of the wave. This place is its so-called bottom, which is located almost at the bottom of the next wave. During installation, it is important that the lower part of the wave coincides with the location of the horizontal bar of the crate. That is why the exact calculation of the distance between the frame boards affects the quality of the roofing arrangement. For example, when installing the most popular type Monterrey metal tiles, it is correct to adhere to the step between the centers of the crate, the size of which is 350 mm. An exception is the laying of the second bar from the bottom of the slope, where the distance should be 300 mm. When installing the no less popular type of Cascade metal tile, the main step will be 300 mm, but the distance between the first and second row of the crate will be 250 mm. And the dimensions of the indent between the second and third row of the crate for roof structure Cascade - 350 mm. This is due to the peculiarity of the texture of the metal tile and the size of the wave (the wave height of the Cascade metal tile is 45 mm, and Monterrey - 39 mm).

Required set of tools

Before making a crate for a metal tile, the craftsmen must take care of the availability of the arsenal of tools necessary for this type of work. These include the following:

Construction stapler.
Wood saw, circular saw or chainsaw.
Hammer or cordless screwdriver (when used as bases for lathing boards, if their thickness allows it, then the connections can be fixed with self-tapping screws).
Level.
Construction marker and tape measure.

The distance between horizontally laid boards can be measured using a measuring bar, the length of which corresponds to the distance between the nearest sides of the horizontally placed boards.

Necessary building materials and "consumables"

Installation of the batten under the metal tile should be carried out on a pre-placed layer of waterproofing and, if necessary, on the structure of the counter batten. For the installation of the supporting frame, the following will be required: Construction Materials:

A board with a section of 25 (32) mm by 100 mm, or bars, the dimensions of which are 50 by 50 mm;
Nails, the length of which depends on the thickness of the boards or bars used. It is better to use galvanized or copper nails, the service life of which is much longer.

When installing this type of metal tile, like the Cascade, the size of the last cornice board in thickness should be on average 15 mm larger than the others. It should also be noted the importance of using dried wood. A board that is not sufficiently dried may deform some time after the assembly of the structure. This can lead to damage to the sheets of metal. In addition, the board must be treated with agents that prevent the occurrence of fungi, mold, and also protect the wood from decay. This procedure can be done with your own hands, having an antiseptic and a regular brush at your disposal.

Step-by-step instruction

After the necessary tools and materials are prepared, detailed diagram installation of the supporting frame is made up, and working surface cleared of foreign debris, you should proceed to the installation of the first board.

Installation of the first board of the crate. It is necessary to start fastening the bars or boards of the roof sheathing from the underside of the slope. To do this, it is necessary to place the frame board in a horizontal order and attach it to the vertical counter-lattice or roof rafters with nails and a hammer. Each junction of the batten elements with the roof surface or the counter batten must be reinforced with at least two nails. The distance between the beams of the crate should be maintained in accordance with the technical characteristics of the selected type of metal tile.
Installation of the second row of battens. It must be remembered that the distance between the first and second row will differ from the subsequent ones, special attention should be paid to this when making the calculation.
Installation of subsequent rows. Further, the crate under the metal tile is mounted with a standard distance, depending on the type of metal tile. A measuring bar is used, the thickness of which corresponds to the dimensions of the boards of the crate, in order to quickly and comfortably fix subsequent rows.
At the inner corners of the roof, where it is planned to equip the valley with your own hands, the base boards are cut at an angle to ensure a tight joint. Also roof valley, chimney or skylights can be equipped around the perimeter with a solid board.

The last row of the crate in the area of \u200b\u200bthe upper ridge should be correctly made wider. To do this, either a wider board can be used, or when attaching standard bars, connect them together, and if necessary, add a few more rows to form a uniform surface. A continuous crate is made to prevent deflection of the edge of the metal tile sheet.

At the last stage, the edges of the frame are trimmed, thereby equalizing their length to a millimeter.

Features of installation and further operation of the roof

Since the installation of the crate under the metal tile provides for high-altitude work, then when doing it yourself, you need to take care of personal safety. Individual insurance should be used correctly, the sole of the shoes used should not slip.

Given the fact that the wood used after installation in most cases still contains a certain amount of moisture, after the first year of operation of the roof, it is necessary to tighten each self-tapping screw with your own hands. Due to the drying of wood, its dimensions are slightly reduced, the roof connection is weakened and there is a risk of water getting onto the surface of the crate along the thread roofing screw, which are fixed sheets of metal to the crate. Calculation required amount components and do-it-yourself installation of the lathing is a crucial step in equipping the roof with roofing. Any installation instructions different kind metal tiles, focuses on the quality and correct installation grounds. At the same time, the calculation of the amount of material for covering the roof, the dimensions of the elements of the crate and all distances must be as accurate as possible, and the requirements for the sequence of work must be strictly observed. For example, when installing metal tiles of the "Cascade" type, bars with a section of 32 mm by 100 mm are mainly used. With such characteristics of the base elements, on average, 3 linear meters of boards will be required to equip 1 square meter of crate. It is quite possible to do such a volume of work with your own hands, however, one should take into account the complexity of the geometry of the roof, the dimensions of the slopes and the total area.

Features of Monterrey metal tile

The metal tile is a metal sheet with a relief pattern imitating an old ceramic tile. Longitudinal and transverse relief gives the sheet rigidity. Monterrey metal profile has the following geometric parameters:

wave height - up to 25 mm;
step length on average 350 mm;
sheet thickness - up to 0.9 mm, sheets with a thickness of 0.4-0.5 mm are more often used. Width and length - 1180x4000 mm.

Having such parameters, the profiled sheet is not very durable, therefore, it is the lathing, installed according to certain rules, that contributes to the durable use of the roofing.

The popularity of the metal tiles of this brand is also due to the fact that it has a large range of colors. Polyester coating ensures the safety and integrity of the metal sheet up to 30 years, appearance - up to 10 years, which is indicated in the manufacturer's warranty documents.

In addition to the above parameters, the material has the following characteristics:

fireproof;
ecologicaly clean;
resistant to environmental influences - rain, frost, sun;
light weight, does not require hardening of truss beams;
ease of installation, repair and replacement of worn or damaged sheets;
the possibility of using as a roof for houses with any roof slope of more than 14 ° and multi-level roofs.

Roof installation sequence

Insulation is laid between the rafters. It will allow you to keep warm in the winter and will not give the opportunity to heat up the air in the attic in the summer.

To eliminate the effect of warm air rising from the lower floors, a vapor barrier material is laid on the heat-insulating material and wooden roof structures. It keeps the load-bearing structures from getting moisture from the room.

On the outer side of the roof, a water-repellent material (film, roofing felt) is laid on the insulation to protect against precipitation, wind blowing and other natural phenomena.

The counter grille is installed between the crate and the hydrobarrier to provide ventilation and prevent the formation of fungus.

The rafters, the counter-lattice and the crate must be made of high-quality wood (pine is more often used - it satisfies all requirements, provided that the boards are properly prepared). The surface of the boards must be smooth without defects, humidity readings - no more than 20%. The boards are treated with special substances that are harmless to humans to repel insects and protect against the negative effects of the environment.

Lathing installation

The board for the crate should be of the following dimensions:

width - 100 mm;
thickness - 30 mm, for the lower row of the crate (near the eaves) - 45 mm.

Sheets of metal tiles are attached to the crate using self-tapping screws with a rubber washer. The protective film is removed from the profiled sheet immediately before installation. Sheets must be laid overlapping each other.

Outcome

The step of the crate under the metal tile must strictly correspond to the distance between the waves, depending on the type of this product.

Self-tapping screws, with which sheets of metal are attached to the elements of the crate, according to the technology, must fix the metal in the most rigid place of the wave. This place is its so-called bottom, which is located almost at the bottom of the next wave.

During installation, it is important that the lower part of the wave coincides with the location of the horizontal bar of the crate. That is why the exact calculation of the distance between the frame boards affects the quality of the roofing arrangement. For example, when installing the most popular type of Monterrey metal tile, it is correct to adhere to the step between the centers of the crate, the size of which is 350 mm. An exception is the laying of the second bar from the bottom of the slope, where the distance should be 300 mm. When installing the no less popular type of Cascade metal tile, the main step will be 300 mm, but the distance between the first and second row of the crate will be 250 mm. And the dimensions of the indent between the second and third row of the lathing for the Cascade roof structure are 350 mm. This is due to the peculiarity of the texture of the metal tile and the size of the wave (the wave height of the Cascade metal tile is 45 mm, and Monterrey - 39 mm).

Required set of tools

Before making a crate for a metal tile, the craftsmen must take care of the availability of the arsenal of tools necessary for this type of work. These include the following:

The calculation of the required number of components and the installation of the lathing with your own hands is a crucial step in equipping the roof with roofing. Any instruction for laying various types of metal tiles focuses on the quality and proper installation of the base. At the same time, the calculation of the amount of material for covering the roof, the dimensions of the elements of the crate and all distances must be as accurate as possible, and the requirements for the sequence of work must be strictly observed. For example, when installing metal tiles of the Cascade type, bars with a cross section of 32 mm by 100 mm are mainly used. With such characteristics of the base elements, on average for the arrangement of 1 square meter of the crate, 3 linear meters of boards will be required. It is quite possible to do such a volume of work with your own hands, however, one should take into account the complexity of the geometry of the roof, the dimensions of the slopes and the total area.
