How to cover the roof with a soft roof with your own hands. Do-it-yourself soft tile roof Preparing a roof for a soft roof

Recently, along with standard roofing materials, flexible roofing has been used. It is made from three constituent elements : fiberglass canvas or cellulose, which is the basis.

The second component is the fill from modified bitumen, acting as a connecting element.

And finally, the third - stone granulate, which is a sandy topping, painted in various shades. It limits the influence of ultraviolet and precipitation on the underlying elements.

Benefits of using shingles:

Waterproof;
The elements are completely resistant to biological attack (moss, fungus, lichen, etc.);
Roof color fastness;
It has light weight which greatly simplifies transportation. Due to this quality, it is not necessary to further strengthen the underlying structures;
The stacking of elements is carried out in such a way that the percentage of waste is reduced to a minimum;
The flexibility of the elements allows the roof to adapt to the deformations and irregularities that occur during operation;
Easy care and.

Roofing always involves the creation of an additional lattice structure, on which further laying and fixing of parts is carried out. It is made of boards and beams located at right angles to the rafters. Depending on the roofing material under which the crate is laid, it is possible to distinguish its several types:

Solid batten step under a soft roof, the gap between adjacent elements is no more than 1 cm. It is used for roofing made of flexible materials.
sparse crate, the elements of which are located at a greater distance. Used for hard roofing. Most often made from boards.

In addition to serving as a base for fastening the elements, the solid grid also performs the role of additional sound and heat insulation.

crate under flexible tiles can be subdivided into:

Single layer, the elements of which are only plank or block elements laid perpendicular to the rafter legs;
Two-layer, which has a more complex structure. It consists of a base, the construction of which is similar to a single-layer lathing, as well as a top decking layer of oriented strand board, plywood, boarding or tongue and groove boards. The elements of the top layer should be located on minimum distance apart, perpendicular to the underlying frame, or at a 45 degree angle, creating a solid structure. Two-layer lathing is used for soft roofing, as well as for a roof with a large rafter pitch.

The structure of the crate for flexible tiles

Requirements for the design of the crate for bituminous tiles:

Sufficient bending strength, allowing the elements to withstand constant loads from the weight of the coating, as well as snow and wind effects;
Resistance to mechanical stress;
Details must be uniform, without knots, bumps and cracks, exceeding 6 mm;
Boards and sheet materials must be straight and not have sagging.

Base mounting

As mentioned earlier, the design of the crate for a soft roof can be single-layer and two-layer. Consider in detail the installation of the elements of each of these options. On the crate, in turn, will fit.

The device of a single-layer crate for a soft roof

For this kind of construction, the following materials can be used: Panel boards (FSF, OSP-3).

Fastening sheet materials is led directly to the logs of the truss system in a perpendicular direction. Such installation is carried out quite quickly, since large items are used.

OSB thickness for flexible tiles depends on the pitch of the rafter legs:

27 mm- for a rafter step of 1.5 m;
21 mm- for a rafter step of 1.2 m;
18 mm- for a rafter step of 0.9 m;
12 mm- for a rafter step of 0.6 m;
9mm- for a rafter step less than 0.6 m;

Adjacent elements are stacked with the formation of a 2 mm gap(if the work is carried out in winter time, then it must be increased to 3 mm). If you neglect this rule, then under the influence of moisture wood materials may swell and bulge. All flooring elements must be treated with antiseptic solutions, as their moisture resistance is not ideal.

When using FSF sheets, their fastening to the rafters is carried out using self-tapping screws or nails, with a step of 150 mm. To select the correct fastener length you need to use the following formula:

L = h × 2.5;

L is the length of the screw or nail;
h is the thickness of the plywood sheet.

Installation of OSB sheets is carried out in a similar way. For fastening, in addition to self-tapping screws, can be used spiral or ring nails. The step between them should be equal to 150 mm, and in the case of using spiral elements, it can be increased to 300 mm.

NOTE!

Self-tapping screws and nails must be driven into the sheet material right up to the head. Thus, the coating will be better protected from atmospheric moisture. You can calculate the number of tiles and the batten system on our website.

At the last stage, the underlying carpet is laid, on which a soft roof is mounted.

Single-layer lathing of tongue-and-groove boards or tess

The basic principle of arranging such a variant of the base for a soft roof is the transverse laying of piece wooden elements right on the rafters.

The width of the boards is usually 10-14 cm.

The thickness is selected depending on the pitch of the rafters, since this distance directly affects the required bending resistance of the boards.

The pattern is as follows:

Rafter pitch from 300 to 900 mm - board thickness 20 mm;
from 900 to 1200 mm - board thickness 23 mm;
from 1200 to 1500 mm - board thickness 30 mm;
For a step of 1500 mm - the thickness of the board is 37 mm;

Installation is carried out from the lower edge of the slope. In this case, the elements must fit strictly perpendicular trays up(for the implementation of the movement of moisture from the rain along the tray to the eaves).

When exposed to moisture and temperature fluctuations, wood changes its geometric dimensions. Therefore, between the ends of the boards it is necessary to arrange a gap of 3 mm. Fastening is carried out using nails or self-tapping screws, hammered as close as possible to the edge edge of the product.

Installation of a continuous two-layer crate

The main difference from a single-layer base under is the presence of the lower frame of the counter-lattice. It is made from boards (25mm × (100-140) mm) or bars (30 × 70mm, 50 × 50mm), by stuffing them onto the rafter base at a right angle. The step of the boards of the counter-lattice should be about 200-300 mm.

The next layer is laid a layer of boards at a 45-degree angle. Between them, as in the case of a single-layer structure made of piece elements, a stabilizing gap of 3 mm is arranged. In addition to boards, plywood or OSB sheets can be used, with or without a layer of insulation (for a warm attic).

The device of the combined crate in steps:

Laying and fixing thermal insulation between truss elements;
A waterproofing film is stretched on this layer, which is nailed to the rafters with the help of bars of the counter-lattice (25 × 30 mm). In the case of a cold attic installation, thermal and waterproofing is not required.
Sheet materials are fixed with a step of 300 mm in places above the rafters, and 150 mm - above the bars of the counter-lattice.

CAREFULLY!

Wood materials should have a moisture content of no more than 20%.

Do-it-yourself installation of rafters under a soft roof

Rafters - elements of the supporting frame of the roof, perceiving and redistributing weather load and the weight of the entire roof on wall structures. In addition, it is the basis for subsequent work on the device of the upper part of the building.

It differs from the construction of a rafter system for other materials only in the presence of an additional crate that provides fastening of small-piece flexible tile elements.

The sequence of installation of the truss frame:

Built at height plank template repeating the design contours of the future roof;
The template falls to the ground. In accordance with its outlines, they are installed and fixed load-bearing rafter legs;
Inside the triangular frame, the remaining elements of the truss are located (braces, racks, puffs, etc.);
All parts are interconnected by rigid connections;
On the bearing walls longitudinally fit mauerlat, which is bars 100 * 150 mm. It is fixed with a wire rod or a hairpin connection;
A supporting log or squared ridge run is installed (in case of a span of more than 6 m between the walls, you will need presetting additional truss structures);
The first farm rises, and installed on one of the ends of the building. It is pre-fixed;
The second farm rises which must be installed on the other end, and also fix with a detachable connection;
A rope is stretched between two farms, with which the verticality of the installation is checked;
The final fixing of the supporting truss system is carried out using a rigid or swivel joint.
The following farms are installed with a certain step. The step of the rafters under the soft roof should be from 0.6 m to 1.5 m. In this case, it must be taken into account that the more, the smaller the step of the rafter legs should be.
On the rafter legs, a single-layer or two-layer crate under a soft top. almost ready.

Conclusion

Soft roofing is one of the innovative options for finishing the upper part of the building. It is practical and convenient to use, and also has high technological and aesthetic operational properties. However, its construction will require a little more effort and time, since you need to take care of installing an additional lattice frame.

In contact with

The crate under the soft roof has its own characteristics. Since such a device is found quite often in the construction spaces of our state, it is necessary to find out the main nuances and varieties of materials for its manufacture. If you properly perform such a roof, you can achieve excellent technical characteristics, including resistance to natural disasters. Plus the ease installation work and low labor intensity of processes cannot leave indifferent all modern developers. In this article, we will consider the device of the crate for a soft roof and get acquainted with all the features and nuances of such a design.

Before you make a crate, you should know which material is better to choose for its manufacture, because each of them has its own individual characteristics. technical specifications. Today there is great amount options, and the most polar among which are the following types:

To create a crate, a cut calibrated planed board with a width of about 14 cm is very often used. The material must be of high quality and reliable. Professional builders recommend preparing it in advance;
The device is often made from wooden block. It is worth noting that special attention should be paid to the moisture content of the wood, which should not exceed 20% of the dry weight. During the workflow, the dimensions of the bars may change, so you need to purchase them with a small margin;
Lathing for a soft roof is created from a roofing or diffuse film material. It has a positive effect on thermal and waterproofing performance;
With the help of roofing runs, you can not only strengthen the roof, but also increase its stability and reliability;
The use of plywood contributes to the creation of a perfectly flat and smooth surface. Plus, in such a device there are absolutely no cracks and cracks, which has a positive effect on tightness.

Attention! Lathing under a soft roof should be created only from materials High Quality and with optimal technical parameters, otherwise you can not dream of a durable and reliable roof.

Types of lathing for soft roofing

The roof lathing for a soft roof is created in order to ensure the fastening of materials to the base of the building surface. Visually, it resembles a frame, as it consists of a series of boards attached to a rafter system. Regarding the type of roof on which it is laid, it has its own characteristics, while there are two main types of battens:

Solid type. Most often, such a crate can be found in a device with soft roofing materials;
sparse type. It is the best option for slate structures, metal tiles and other solid roofing projects.

Most often, a crate for bituminous tiles and others soft materials produced by technology in two layers. First, one continuous level is made, for which a chipboard (chipboard) is used. It is worth noting that they can also lay moisture-resistant plywood. Then lay a sparse layer made of boards.

Attention! Such a device allows you to increase the efficiency of heat and sound insulation in the room.

Installation of lathing under a soft roof

The installation process of the crate is quite simple. To create a high-quality and effective coating, you must follow the following sequence:

We fasten the bars of wood from the bottom up to the load-bearing points of the roof;
We nail the lower purlin behind the eaves with a board;
Then we lay the roofing tape horizontally to the roof ridge. First, we make a strip at the eaves, gradually rising with an overlap to the top. In order to facilitate the gap of the ventilation system, we fix the material between the counter-lattice of the bars and the rafters;
After we fix the first bar to the very edge of the rafters;
We mount the second bar at a distance of about 30-35 cm from the lowest point of the first frame element;
We continue the installation of the bars, maintaining the step of the crate under the soft roof - 37 cm. We attach the last element to the ridge 20 cm with nails;

Attention! All elements of the crate must be mounted in a horizontal position. If you meet the requirements regarding the distance to the lower edges of the structure, then you can achieve excellent indicators of strength and reliability.

As you can see, the installation process does not require special skills, but there are many nuances, without adhering to which you can ruin the coating. It is best to find a specialist in your assistants.

Rules for mounting the crate relative to the corner

Before writing this section, we watched a lot of videos and outlined the basic rules that will help you create the perfect roof arrangement. Lathing for a soft roof should be created taking into account such nuances:

For roofs with an angle of less than 10 degrees, it is necessary to make a continuous type crate. For this, it is best to use moisture-resistant plywood;
If the angle varies from 10 to 15 degrees, then the crate is made in increments of 45 mm. To create a device, it is optimal to use timber and waterproof plywood. The structure should be directed parallel to the eaves of the building;
If the angle exceeds 15 degrees, then the step should be increased to 60 cm. To create a structure, a beam with a size of 45 by 50 mm is best suited;
An additional beam should be installed in those places where the valleys and the ridge will be attached.

The best material for the manufacture of lathing under a soft roof should be considered a calibrated board. Thanks to equal thicknesses, an even joint is obtained and a stepped design is avoided. Practical experience proved that such surfaces can last much longer than uneven roofs. It is for this reason that developers buy quality material and try to match the boards as accurately as possible.

Attention! The best wood for these purposes are considered conifers, which please with both cost and excellent technical characteristics.

Recommendations regarding the load and parameters of the crate

The optimal step when creating a crate for soft roofing materials is considered to be a value not exceeding 10 cm. This norm is caused by certain characteristics of the products. For a continuous layer, a calibrated edged board, which has already been mentioned above, is ideal. It will also help you create the perfect flat surface without seams - waterproof plywood and chipboard sheets. It should be borne in mind that this layer must be tightly attached to the boards and have a moisture content not exceeding 20%. When creating a structure, we pay attention that its strength corresponds to the load that will put pressure on it:

Take into account the possible load from snow cover;
Calculate the load that is created from the roofing materials.

Relative to these indicators, the necessary parameters of the crate are determined. Thus, if the laying step is about 50 cm, then a board with a thickness of at least 20 mm should be used, and with a step of 120 cm, at least 30 mm. It is worth noting that one of the features of a soft roof is resistance to biological damage, but this does not apply to the tree from which the crate is knocked down. For this reason, it is recommended to perform special treatment with antiseptics that will protect the structure from fungi.

Features of installing a drip

The dropper is considered important element in the device of the crate for a soft roof, as it is responsible for protection against the adverse effects of moisture. The bending of the product depends on the angle of the roof, its value varies from 100 to 130 degrees. Attach the dripper to the edge of the roof, vertically directing it down so that the water flows to the ground. Features include the following:

For the manufacture of the dropper, galvanized steel is used, which does not tend to rust;
In order not to spoil the aesthetic appearance of the building, the color of the drip should be matched to the shade of the roof;
To fully protect the roof and facade, you should stretch the drip around the entire perimeter of the building;
The device is able to provide protection against wind currents.

So we got acquainted with all the features of creating crates for buildings with a soft roof. Follow all the tips and tricks, and you will definitely succeed!

Recently, more and more offers have appeared on the building materials market, which are quite difficult for a non-professional to understand. For roofing, the most common materials are metal tiles and steel sheets. For erection own house it is worth considering such an option as a roofing device from soft tiles. In terms of technology, it is somewhat different from the usual materials, but it has many advantages that make it a strong competitor.

What is soft tiles

The title is conditional. The material is rather sheets of fiberglass impregnated with a bituminous binder with the addition of rubber. Features of the composition dictate some requirements in the production construction works and operation. The covering sheet is called shingle.

To increase the protective properties, the front surface is sprinkled with stone chips. This allows the material to acquire greater resistance to mechanical damage. The advantages of using soft tiles for roofing with your own hands include the following characteristics:

attractive appearance;
ease of transportation due to the compact size of the products and their relatively small weight;
simplification of the process of lifting material to the roof;
do-it-yourself installation is easier;
lack of noise during rain or wind, a roof made of such material absorbs unnecessary sounds and contributes to comfortable rest in home;
a wide variety of colors.

In addition to the advantages, installation has several disadvantages:

a roof made of such material is not the most budget option;
the technology provides for the installation of a continuous crate with your own hands, which greatly increases the consumption of wood (the main costs for the construction of the roof go exactly to the crate), the roof pie turns out to be expensive;
there are restrictions on the angle of inclination, because with a steep slope in summer period upper layer shingles can melt and move relative to its original position;
an increase in the mass of the roofing, this value cannot be compared with ceramic tiles, but still it is slightly larger than when laying a metal roof in a pie.

After the decision was made to complete the roof pie of the house using soft tiles, you need to think about laying it yourself. Installation is not difficult, but the technology has some features. The following work recommendations can be made:

Material after purchase is stored indoors. Sheets are stacked in a horizontal position in pallets, the height of which is taken no more than 16 rows. The underlayment carpet, which is used for priming and leveling the surface under the tiles for storage, is placed in a vertical position.
To create favorable temperature conditions in the under-roof space, thermal insulation will be required. The selection of the type of insulation is carried out depending on the preferences and financial capabilities of the owner of the house. The most common installation mineral wool. The laying technology of this material assumes the presence of reliable waterproofing and vapor barrier. In addition, to remove liquid vapors from the surface of the insulation between it and the roofing, a ventilated air gap, whose average width is 5 cm.
At the time of buying roofing material it is important to pay attention to the batch of goods. The roof will look better if you use materials made at the same time in one place. In this case, an exact match in color and physical characteristics can be guaranteed.
Installation of soft tiles is not carried out at low temperatures. This is due to the fact that the material becomes brittle in the cold and can be easily damaged when fixed in a cake.
For laying the material with your own hands, the minimum slope angle should be 15 degrees. Installation at a lower level does not guarantee waterproofing, since the liquid moves rather slowly over the surface and can easily flow into small gaps. In this case, it is worth considering the rule that the roof slope cannot be too large for bitumen and remember that the more the roof is tilted, the more material is required for the cake.
Do-it-yourself installation of soft tiles is carried out without the use of a burner. This material does not belong to the class of built-up materials. For additional fixing (with strong wind loads), special adhesive solutions are used.
Peel off the transparent protective film from the inner surface immediately before laying on the cake.
When doing work with your own hands, it is important to remember that it is not allowed to walk on the roof without special devices in sunny warm weather. This is because the material melts slightly when exposed to sunlight, and the installer may leave shoe marks on the surface that cannot be removed without replacing part of the coating.
A solid material is used as a base for tiles. The pie may include a solid crate or a sparse one, followed by laying moisture-resistant plywood on it. Installation directly on the heater is prohibited.

Roof construction technology

To properly make a roofing pie for shingles, it is recommended to follow the following procedure:

installation of the truss system;
laying a waterproofing layer and installing a ventilated layer;
fixing the crate (solid or sparse);
if necessary, a continuous layer of moisture-resistant plywood;
installation of roofing;
laying insulation between the rafters;
fixing the vapor barrier;
inner lining.

Some of these structures included in the roofing pie should be considered separately.

crate

When constructing a continuous layer of boards without subsequent leveling with plywood, the following requirements for surface quality are observed:

lack of gaps, ledges, irregularities;
the thickness of the board is selected depending on the step of the rafter legs; large sections should be taken to ensure reliability (a board of 32-50 mm is suitable);
normalized moisture content of wood is not more than 20%;
boards must be durable, without damage with mandatory antiseptic treatment.

Fulfillment of these requirements will ensure a snug fit of the roofing material to the surface, which will prevent roof leaks. Along the perimeter of weak sections of the roof, it is required to lay a lining carpet, which will increase the reliability of waterproofing. Possible places where a roofing cake may leak are:

valleys;
adjunctions to the roof of dormers and dormer windows;
exit to the outside of ventilation pipes and chimneys;
antenna installation locations.

The best option, which is most often used by professional builders, will be a solid plywood flooring on a sparse crate.

Such a cake provides a high bearing capacity.

Ventilation system

It removes moisture from the surface of the insulation. As mentioned earlier, the minimum gap is 5 cm. The main elements that must be provided for the normal functioning of the system:

products in cornice overhangs, which can be closed with perforated spotlights or a sparse board fastening;
gap between thermal insulation and waterproofing;
ventilation outlets in the roof ridge (aerators).

Mounting material

Laying starts from the bottom of the roof. It is important to pay attention to the likely places of leaks. Difficulties arise mainly on the valleys. Laying bituminous tiles on a slope and a ridge does not cause any particular difficulties.

Scheme of laying a soft roof

The lower part of the shingle is attached to the surface of the slope with an adhesive layer. For the top, you will need to prepare four nails for each element. Fasteners have a feature - wide hats, so as not to damage the roofing material. The laying of the material is carried out with an offset of the rows (dressing), the value of which is assumed to be 50 cm.

Soft roofing is a term that combines a range of flexible roofing materials with excellent consumer qualities. Its piece and roll varieties flawlessly protect the house from atmospheric "misfortunes" and effectively decorate the exterior. They weigh little, do not require effort in cutting and fastening. Among the pluses, the ability to lay the coating with one's own hand appears solidly.

For an ideal result, it is not necessary to have the skills of a roofer. You need skill, patience, a tool and information about how the technology of laying a soft roof differs from other methods and how to properly arrange a roof.

Materials from the group of soft roofing are modified versions of the good old roofing material. New developments borrowed from their predecessor the flexibility and lightness that rightfully top the list of advantages. Kept steadfast water repellency which make it last longer wooden base and truss system. The composition has improved, due to which the terms of the impeccable work of materials have increased threefold.

With a focus on the laying method, the class of soft roofing is divided into three types:

Roll materials, supplied in the format corresponding to the name. These include bituminous descendants of roofing material and new representatives, such as polymer membranes. Roll coverings stacked in stripes. Bituminous materials are fastened by fusing, polymeric materials - by partial or complete gluing. With their help, they mainly equip flat and sloping roofs with slopes up to 3º, up to 9º is acceptable. Rolls are in demand mostly in industrial construction;
Roofing mastics supplied ready-made or cold to be heated. Sprayed or applied in a thick layer on flat roofs, resulting in a monolithic coating without seams. Reinforcing mesh is used for reinforcement. The scope of application is limited to flat roofs.
bituminous tiles supplied in flexible shingles. In fact, this is an improved roofing material, cut into relatively small sheets. The edge of the shingles is decorated with figured petals to imitate a ceramic prototype. The back side is equipped with an adhesive strip designed to be attached to a wooden base. Glue piece by piece. Additionally, roofing nails or self-tapping screws are hammered into each shingle. From the heating of the bituminous roof by the sun's rays, the tiles are sintered and turned into a continuous roofing shell.

In private low-rise construction, a piece variety is actively in demand, because. flat and low pitched roofs over one- or two-story residential buildings very rarely built. Household buildings have a “flat” fate, but not every owner decides to buy membranes and mastics for the roof of a barn. So, we will pay attention to the installation of the most popular shingles.

Step by step installation of shingles

piece flexible material cover roofs with any steepness and degree of architectural complexity. True, bituminous tiles are not recommended for roofing if the angle of inclination of the slopes is less than 11.3º. The material is produced by numerous manufacturers. Each of them seeks to communicate own products unique qualities and useful properties for the stacker.

Despite some differences, the soft roofing technology is carried out according to the same scheme. There are small nuances, but they are not fundamental.

Foundation preparation rules

Flexibility - advantages and disadvantages bituminous coating. On the one hand, it allows you to noticeably speed up the process. After all, it takes a little time and a minimum of effort to form junctions, sinking pipes, arranging valleys and cornices. On the other hand, due to the flexibility of the material, a continuous batten is required so that the flexible shingles rest completely on a solid, even base.

You can build a continuous crate before installing a soft roof:

from OSB-3 boards, recommended based on budget cost and sufficient strength;
from sheets of moisture-resistant plywood with the FSF marking;
from grooved or edged board, the humidity of which should not be less than 20%.

The sheet material is laid in a masonry-type run-out. It is important that there are no cruciform joints. It is necessary that the weak areas of the joining of the plates are evenly distributed over the counter-lattice. In the seams, gaps of 2-3 mm should be left, which are required for the free movement of the truss system during temperature fluctuations.

Plank flooring is installed parallel to the roof overhangs. Also in a run, if the length of the board is not enough for the slope. The place of joining of two boards on the slope should be supported on the beam of the counter-lattice, four nails should be hammered into it. Ordinary boards are fixed with two nails on both sides. They must be laid so that there is a gap of 3-5 mm between the longitudinal elements. Edged boards are sorted before work. Those that are thicker should be distributed at the base of the ramp, those that are lighter should be sent up.

Ventilation is the key to perfect service

The excellent water-repellent properties of the bituminous coating are due to the scanty number of pores that can pass moisture and air. Reliable hydro-barrier acts in both directions. inside roof structure raindrops do not penetrate, but the steam does not come out. If you do not provide a free path for evaporation, condensate will accumulate on wooden roof trusses and crate. Those. a fungus will start, because of which you will have to say goodbye to a solid roof.

In the name of long-term flawless service, it is necessary to arrange a system roof ventilation including:

vents designed for air flow in the area of cornices. In addition to the inflow, they are required to ensure the free movement of air from the bottom up along the planes of the slopes. The vents are open channels formed by a crate and a counter-crate;
ventilation gap between bituminous roofing and laid on top of the vapor barrier insulation. It is intended for washing with an air stream of a heater;
holes in the upper zone of the roofing cake. These can be either ends of the slopes that are not closed at the top, or specially arranged vents with a plastic barrel resembling a miniature chimney.

Ventilation must be arranged in such a way as to exclude the formation of air sacs in the under-roof space.

Laying an insulating carpet

It is highly recommended by all shingle manufacturers without exception to lay an additional waterproofing mat before installing the shingles. The list of materials suitable for carpet is usually indicated in the briefing. The product specified or equivalent in terms of characteristics is approved for use.

Replacement is highly undesirable, tk. a compound that is incompatible with the coating will prevent the bituminous layers from coalescing into a monolith and will promote swelling. Polyethylene is excluded. Ruberoid too, because the service life of a flexible roof is longer. It is unreasonable to lay a less durable material under a coating designed for 15-30 years of operation.

The technology of laying an insulating carpet under flexible tiles includes two options, depending on the steepness of the roof:

Installation of a solid carpet on pitched roofs with a slope angle from 11.3º / 12º to 18º. Roll waterproofing lay in strips, starting from the overhang, moving towards the ridge. Each strip laid on top should overlap the previous strip with its own ten cm. If you need to join two segments in one row, they are laid with an overlap of 15 cm. The overlap is carefully, but without fanaticism, smeared with bituminous mastic. To the base of the insulation strip are attached roofing nails after 20-25 cm. On top of the solid carpet, strips of barrier water-repellent protection are laid in the valleys and on the overhangs, as well as around the roof junctions. Then the ridge and convex corners of the roof are equipped with the original insulating material;
Laying partial insulation on pitched roofs with a slope of 18º or more. In this case bitumen-polymer material valleys and overhangs are protected, and only the edges of the gables, the ridge and other convex corners are covered with strips of an insulating carpet. Insulation, as in the previous case, borders the intersections of the roof with pipes of communications and roof connections. bituminous width polymer barrier along overhangs 50 cm, in valleys it is 1 m, so that each of the protected slopes has 50 cm. When laying around junctions and pipes, the insulating strip is partially led onto the walls so that 20-30 cm of the vertical surface overlap with the material.

The device of a flexible roof with partial waterproofing is allowed by manufacturers, but among them there are no ardent supporters of this method. Naturally, precipitation is less delayed on steep slopes, but the circumstances are different: ice, slanting rain, etc. Better to be safe.

The bitumen-polymer carpet for the valleys is selected to match the tiles. A slight deviation from the color of the coating is allowed if there is a desire to emphasize the lines of open grooves. It is desirable that the valleys are covered with a continuous strip of barrier insulation. But if the joining of two pieces cannot be avoided, it is better to arrange it in the upper part of the roof with an overlap of 15-20 cm. There is the least load. The overlap must be smeared with bituminous mastic.

Protecting gables and eaves

The roof perimeter is equipped metal strips. They are needed to protect the weakened sections of the crate from moisture and as roof design elements. The slats are laid on the edge of the gables and overhangs with an edge. The rib line must match the outline line of the roof. Fasten with roofing nails in a zigzag pattern after 10-15 cm.

If it becomes necessary to join two planks, they are laid with an overlap of 3-5 cm, at least 2 cm. The gable planks overlap the eaves at the corners of the roof. In places of end and docking overlaps, fasteners are driven in after 2-3 cm.

Most resilient roof manufacturers advise installing both types of metal protection over the underlayment. However, the developers of the Shinglas brand recommend that the cornice strips be placed under the carpet, and the gables on top of it. Before installing the pediment and cornice planks on the plank sheathing, they also advise first nailing the bar, and attaching a metal protection to it.

Formation of passages through the roof

Roof-crossing chimneys, utility risers, antennas, own ventilation holes need special arrangements. They create a potential hazard in the form of an open path for water leaks. Therefore, before installing the coating, the places of the roof penetration are covered with sealing devices or systems. Among them:

Rubber seals designed to close points of small diameter. Antenna holes, for example;
Polymeric passage elements used for equipping roof intersections with sewer and ventilation risers. They are produced specifically for the arrangement of roofs. Passers are fastened with corny nails to a continuous crate. Bituminous tiles are laid on top, which in fact are cut around the passage and fixed with bituminous mastic;
Plastic adapters for own roof ventilation. Close the holes with vents, ridge element with evaporative channels, perforated fittings for cornices.

The rules for arranging the passages of large chimneys should be considered separately. In addition to the threat of leaks, they are also a fire hazard. Chimneys are sealed in several stages:

the walls of the pipe are protected by parts cut from asbestos-cement slabs according to its actual dimensions;
along the perimeter of the pipe, a triangular bar treated with flame retardant is mounted. To make it, you can split a bar diagonally. A skirting board is suitable for replacement. The bar for arranging the chimney is not attached to the crate! It must be fixed on the walls of the pipe;
lay flexible tiles, winding the shingles on the bar;
details are cut out from the valley carpet according to the size of the pipe with set bar. The width of the parts is at least 50 cm. Patterns are fastened with a 30 cm lead to the pipe walls with glue or bituminous mastic. First, the front part is glued, then the side parts, and finally the back part. The lower edge is placed on top of the laid tiles, the upper edge is inserted into a stab on the pipe wall;
at the end, the multilayer insulation system is fixed by installing a metal apron with the treatment of the joints with silicone sealant.

There is a simpler and cheap way: the details of the insulating lining of the pipe are not cut out of the carpet, but immediately from galvanized metal. Then half of the stages of work will disappear by itself.

Wall junctions are sealed in a similar way. Only there is no need to install asbestos-cement protection, and the surfaces to be protected must be plastered and treated with a primer before arrangement.

Rules for laying cornice shingles

In order to create guidelines for the installer, it is better to pre-mark the roof with coated building cord. Horizontal lines are applied with a step equal to five rows of flexible tiles. Verticals are beaten off with a step of one shingle.

After preparing and marking the roofing surface, you can safely start laying flexible tiles, following the algorithm:

the cornice row of tiles is mounted on the overhang first. You can take a special ridge-cornice tile or cut out the starting element with your own hands by cutting the petals of an ordinary ordinary tile. From the edge of a metal eaves plank you need to step back 0.8-1cm and glue the cornice shingle. For gluing from the adhesive layer, you need to remove the protective tape, and coat the remaining places with mastic;
laid eaves tiles fixed with roofing nails in increments equal to the width of the petal. wide hat when hammering, the hardware must be strictly parallel to the surface of the continuous crate. Skews are not allowed. Nails are hammered, stepping back from the upper edge of the shingle 2-3 cm. Fixation points should overlap with the next row of roofing;
the first row of shingles is laid. It is better to start from the center of the slope, so that it is easier to align horizontally. 1-2 cm should be retreated from the bottom line of the starting row and glued in an already tested way. Nailed with four nails at a distance of 2-3 cm from the groove between the petals;
installation of the second row is also more convenient to start from the middle. But the shingle must be shifted so that the tab is above the groove of the first row of tiles and the attachment points are completely closed;
the upper corner of the tiles laid next to the pediment is cut off in the form of an equilateral triangle with sides of 1.5-2 cm. pruning is needed to break the water.

You can continue laying shingles in a linear fashion, i.e. stacking the entire row, one after the other. It is possible according to the pyramidal method with “building up” from the middle of the slope to the edges or diagonally.

Two ways of arranging a valley

Two methods have been developed for the formation of the valley:

Open groove device. Roof tiles laid up to the axis of the valley on both adjacent slopes. Only nails stop hammering already at a distance of 30 cm from the axis. After laying with a coated cord, the valley lines are beaten off on the slopes, along which the coating is carefully trimmed. The width of the groove is from 5 to 15 cm. In order not to cause damage to the soft roof during cutting, a plank is placed under the tiles. The corners of the tiles located near the valley are cut to rebound water, then backside coating elements are coated with mastic and glued.
Closed groove device. Tiles are laid first on a slope with the smallest slope so that approximately 30 cm of material is located on an adjacent slope. At the top, the shingles are fastened with nails. After that, the second slope is covered, then a line is beaten off on it, stepping back from the axis of 3-5 cm, along which cutting is made. The corners of the tiles are cut to repel water, after which the cut loose elements are glued to the mastic.

The nuances of laying tiles on the ridge

Upon completion of the installation of tiles on the slopes, they begin to equip the ridge. ventilation ducts in the body of the crate should be left open, so a gap of 0.5-2 cm is left between the tops of the slopes. To ensure ventilation, the skate is equipped with a plastic aerator. It is not very attractive, therefore, for the sake of aesthetics, it is decorated with universal ridge-cornice tiles or tiles cut from shingles.

Nail the tiles with 4 nails. Each subsequent element must cover the fasteners of the previous one. Tiles are mounted on the ridges from the bottom up. The ridge is equipped in the direction of the prevailing winds so that open areas turned to the leeward side.

In detail, the process of installing a soft roof with explanations of the step-by-step laying technology will demonstrate the video:

No special difficulties were found in the construction of a soft roof. There is technological features. If they are strictly observed, styling can be done independently with excellent results.

The soft roof adapts perfectly to any geometric features roofs. Such roofing is popular and in demand due to a significant number of advantages, and besides, soft roofing is very affordable. In order to obtain a high-quality and durable coating using a soft roof, it is necessary to fulfill a number of prerequisites, the main of which are the competent arrangement of the frame, lathing and roofing cake, as well as compliance phased technology all installation work.

The device of the frame and roofing pie

Installation of any base begins with the device frame structure. Features of a soft roofing require the implementation of a high-quality roofing cake, the basis of which is a heater.

In spite of a large number of options for performing thermal insulation, the most successful is the placement of insulation between the truss system. Standard sizes heat-insulating boards are sixty centimeters. Based on these indicators, the frame of the truss structure should be carried out.

Basic requirements for the material used:

the width of a high-quality edged board should be at least fourteen centimeters;

wooden blocks should have a moisture content of twenty percent, and dimensions this lumber is changed in the process of making the crate base;

instead of a diffuse film, you can use a roofing one;

do not forget about roofing runs, which increase the reliability of the structure.

Mounting technology

To obtain a continuous coating, the wooden base is mounted in two layers. Such a coating should be devoid of sharp corners and creases, which minimizes kinks and friction of the soft roofing.

To fulfill correct device roof lumber is located with trays up, which allows seeping moisture to flow down, and not through the joints into the under-roof space.

Standard sheathing step for a soft roof depends on several factors, the fundamental of which are the roofing slope, the strength of the winds and the degree of windage of the roofing material. As a rule, it is equal to 40-60 cm.

Laying the base for flexible tiles

Plywood and OSB is optimal material for lathing under flexible tiles. It has multi-layer, moisture resistance and flexibility, which provides high level functionality and long service life.

It is most expedient to use FSF plywood from softwood treated with refractory and antiseptic compounds.

Features of the implementation of a solid base for flexible tiles:

for laying sheets of medium size are used, the longitudinal part of which must be laid parallel to the ridge;

it is necessary to use the “staggered” laying method not only for sheet plywood, but also for bars of the counter-lattice;

between plywood sheets, it is required to make gaps with a width of two to three millimeters, which will compensate for the swelling of the material in case of wetting or temperature changes;

to fix plywood sheets on the beams, self-tapping screws or ruffed nails are used, the caps of which must be completely drowned;

the step for fasteners is no more than fifteen centimeters.

Summing up

under a soft roof, it is necessary to carry out two layers of the base;

it is necessary to achieve an absolutely smooth and even finish layer of a continuous crate;

the optimal indicator for the thickness of sheet plywood should be twelve millimeters with a beam pitch in the counter-lattice of 60 cm, nine millimeters with a beam pitch of less than 60 cm and eighteen millimeters if the lathing pitch exceeds 90 cm;

mounted on the installed solid crate lining carpet, and then a covering from a flexible tile.
