Ridge for a roof from a professional flooring. How to cover the roof with a profiled sheet: step by step instructions, processing knots How to fix a ridge profile

Quality roofing for your home reliable protection from leakage and destruction, which will primarily provide coziness and comfort.

Steel is one of the most durable and durable materials, but its only drawback, as a roofing material, was its weight. The totality of heavy sheets in total gave a huge mass, which negatively affected the roofing frame. The problem that arose was solved by the corrugation method steel sheet, which, having a small weight in relation to size, retained its strong and rigid qualities due to the trapezoidal profile design - this is how corrugated board arose.

He for several recent years gained great popularity due to practicality in use, as well as minimal harm to the environment.

Decking - what is it, its pros and cons

Profiled flooring is produced by cold rolling from hot-rolled steel sheet. During production, it is treated with several layers of protection to increase strength and durability. At the initial stage, the workpiece is treated with anti-corrosion phosphate and only then it is primed. The upper part of the sheet is covered with a mixture of polymers, and the lower part is covered with a special varnish.

Thanks to the work done, the result is durable material High Quality, which combines much more pluses than negative qualities.

Service life of the material;
Competitive price with other types of roofing materials;
Material weight;
Simplicity and time saving during installation and dismantling;
Resistant to temperature changes.

The disadvantage of corrugated roofing is low level noise reduction, due to which the sound insulation deteriorates significantly.

Types of corrugated board

The widespread use of corrugated board and not only in roofing has divided all its types into three classes:

H - for coatings and ceilings, as well as fixed formwork(best roofing material). Additional stiffening ribs, corrugation thickness and height make it the most reliable and durable option.
C - for fencing fences and walls. This option is much cheaper than the previous one. The thickness of the sheet is less, respectively, the service life and reliability are significantly inferior.
HC - combined corrugated board. The brand is also often used in roofing, but in most cases for unloaded roofing. It all depends on the angle of the roof slope, which is an important factor in winter. A thin sheet of steel and a flatter roof structure can be fatal under snow pressure.

Roof slope

For proper styling corrugated board, it is necessary first of all to take into account the slope of the roof. This will help calculate the desired overlap with the adjacent sheet.

When the roof slope is less than 15° or more than 12°, the overlap of sheets must be at least 20 cm;
In cases of inclination angle 15°-30° - from 15 to 20 cm;
The slope of the roof above 30 ° allows you to reduce the overlap to 10-15 cm;
A slope angle less than 12° requires additional work for sealing overlaps using silicone sealant.

Preparatory work

Before the laying process itself, it is worth carefully and correctly calculating the amount of roofing material and its type. You can do this yourself or use the service of a company whose manager will help you.

During transportation and loading, avoid strong bends, and also ensure flat surface vehicle that will carry the material.
Manual unloading provides for every 2 m of length of one worker. When using lifting equipment, it is necessary to use soft slings.
Transportation to the roof is carried out using a log to connect the edge and the ground, not exceeding the norm in one sheet.

AT without fail you will need such a tool as: a tape measure, a hammer, a hacksaw, a cord, a rail, a drill and drills.

Waterproofing and ventilation

Moisture released from the premises of the house always collects under the roof. To prevent this, it is necessary to organize the roof in such a way that the temperature outside and under the roof are the same. To achieve this goal, you need to take care of the correct vapor and thermal insulation, as well as ventilation.

Waterproofing is most often mounted before fastening sheets of corrugated board to the crate.

where 1 - rafter leg; 2- waterproofing; 3- truss slats (beam konrobreshetki); 4 - crate.

Advice from the pros: waterproofing film install in such a way that it hangs slightly, by about 20 mm, in a position perpendicular to the roof slope. Installation should begin from the lower edge of the roof to the ridge. Its overlap, sealed with adhesive tape, should be 100-150 mm.

The method of laying the film on the rafters:

To ensure the most efficient movement of air flow from the eaves under the crest of the roof, organize ventilation holes between the ridge batten and the roofing sheets. In places where air flow is difficult, it is necessary to do more additional channels for ventilation. However, the most in a simple way is the placement of wooden slats directly on the waterproofing layer.

Rafter strips and lathing

Rafter strips or steel girders are mounted on top of the hydro and vapor barrier if the profile height becomes 40 mm. Further, a crate is attached to them in the longitudinal direction, the step of which depends on the type of corrugated board.

To organize the crate you will need:

beam size 50x50 mm;
board 32x10 mm;
moisture resistant plywood sheets with a diameter of 10 mm.

The crate is of two types: solid and thinned. The first type is installed on the ribs, skates and around chimneys. The thinned pitch is 50 mm. Lay the boards at the same distance, this will facilitate the entire further process of fastening corrugated sheets.

All wooden details be sure to treat with an antiseptic and fire-fighting mixture.

Experts advise laying a so-called diffusion gasket on top of the crate, which will prevent the formation of condensate. It is fastened with small nails with a wide hat.

The arrangement of the crate should be taken with special responsibility, since the reliability of the entire structure largely depends on it.

There are also no exact standards for the thickness of the crate, it all depends on the same parameters of the profiled sheets and the length of the fasteners. Minimum dimensions cross-sections of the lathing become 32/100 mm. The board that is located along the eaves should be a little thicker than all the others. Near the chimney, it is necessary to organize the fastening of additional boards.

Eaves overhang

Lay the bottom row on the crate roofing sheeting, thus forming eaves overhang. Its dimensions completely depend on the height of the profile sheet.

However, initially it is necessary to take care of the cornice strip, which must be organized below the waterproofing layer. This is necessary in order to wastewater and the resulting condensate fell into cornice plank, along which flowed into the catchment area, and then along drainpipe. Otherwise, water will flow down the walls of the house, which will cause negative consequences.

Installation of corrugated board

It should be noted right away that the installation of corrugated sheets should be carried out strictly according to the instructions.

Cutting of corrugated board

Of course, it is better to purchase sheets of corrugated board on the market that match the size of the roof, but often these two parameters do not match, so you need to know how to cut correctly and which tool is best to use for this.

The adjustment of the material must be carried out on a flat plane, for example, on the ground.

For these purposes, you can use various instruments, however it is best to use electrical devices like a drill with a disc nozzle. If you could not get such a tool, then you will have to cut it manually with steel-based metal shears or a hacksaw with fine teeth.

It is forbidden to use mechanisms with an abrasive cutting working disk, for example, a grinder, to cut sheets of corrugated board. The reason is that such devices emit relatively large heat energy during operation, which negatively affects performance material.

When cutting roofing material, the edges will not be without damage, so you need to take care of the paint in the color of the corrugated sheets in advance.

We raise sheets of corrugated board to the roof

During the lifting of the roofing corrugated board to the roof, difficulties often arise due to the dimensions of the material, therefore, for comfortable work, it is best to perform this stage of work with the help of a log.

They should be installed in such a way that on one side they rest against the ground, and on the other side directly against the eaves of the roof slope.

Between the planks there should be a distance slightly less than the width of the corrugated sheets themselves. Thanks to this system, two people can easily lift roofing sheet for further installation. You can replace the logs with an ordinary staircase without a railing.

Fastening sheets of corrugated board

Roofing with corrugated board should be carried out, observing the following technology:

Sheets should be fastened with 80 mm hex self-tapping screws and a sealing gasket. At the same time, it is worth remembering that you cannot overtighten the screws, as this can lead to excessive gasket density, as a result of which the waterproofing layer may suffer.

Sheets should be fastened at the bottom of the wave, and in ridge elements and in places of overlap - at the top.
It is best to start installation from the end of the slope. The side overlap should go halfway up the wave of the sheet. However, if the slope is gentle (the angle of inclination can vary from 8 to 120 degrees), then to avoid leakage, the overlap should go 1.5 waves.
At transverse and longitudinal joints, it is necessary to make additional sealing with self-adhesive tape or bituminous mastic.
The front parts of the roof should be equipped with wind plates that will protect the corrugated roof from destruction and blowing. They need to be fixed with self-tapping screws, the pitch of which is 200 mm.
Depending on the height of the wave, the length of the self-tapping screw L is also selected, which is equal to:

L= L1+H+L2, WHERE

L1,L2 - respectively the profile thread (about 25 - 30 mm) and the thickness of the washer with the seal (about 3-4 mm), H - the height of the corrugation.

Approximately 5-8 self-tapping screws should be used per 1 m2.

Making a gable cut

To prevent breaking sheets of corrugated board during strong gusts of wind, it is necessary to properly equip the gable cut.

If the allowance of corrugated board sheets from the front of the house is 50-70 mm, then a wind rail with dimensions of 25x80 mm is used, which is fastened with self-tapping screws. If the allowance from the front of the house is insignificant or not at all, then in addition to the rail, a wind bar is also used. It looks like an ordinary steel corner. It must be fastened in increments of 200-300 mm and with a transverse overlap of 100-150 mm.

To adjoin the slope to the wall, apply corner strips. Planks, regardless of the type of junction - longitudinal or transverse, should be mounted using self-tapping screws with a pitch of 200-300 mm and an overlap between these planks of about 100 mm or more.

Cross connection to the wall:

Longitudinal junction to the wall:

Installing the skate and snow barrier

Start the installation work associated with fastening the ridge, follows from the side that is less prone to gusts of wind and leaders. For example, if for your area the west is considered the predominant windy side, then it is better to start fastening the ridge from the east. It can be simple, figured or tiled. The fixation of the ridge is carried out using self-tapping screws with a pitch of 200-300 mm, also do not forget about sealing gasket and ventilation gap.

The snow barrier is especially relevant during the thaw, it prevents avalanche snow from metal roofing. It must be installed slightly below the edge of the roof across the roof slope. Fastening is carried out in pre-mounted bars.

Roof insulation from corrugated board

To insulate the roof, you will need mineral wool and a vapor barrier. Together with mineral wool, you can also take Durra insulation, but this one is the most effective.

And so ... we go down from the roof to the attic and you can proceed to the final stage of arranging the roof from corrugated board.

Mineral insulation can be rolled or sheet, whichever you choose - it does not matter, since both have excellent performance properties. It is mounted in the gap between the rafters, any method can be used for its fastening - screw it with screws, fix it tightly with a thread or glue it. The main thing is that any of them perform their functions, and at the same time do not unnecessarily compress the seal, since it is not the cotton itself that keeps the cold outside, but the air that is located in it.

2 crate; 3 - sealant; 4 - skate; 5- layer of waterproofing; 6.7 - rafter bar and leg, respectively; 8 - mineral wool; 9- vapor barrier; 10- ceiling rail; 11- lining or some other finishing material; a - roof ventilation; b - ventilation between waterproofing and mineral insulation.

Then a vapor barrier should be attached over the mineral wool. It is necessary in order to prevent the ingress of moisture that is in the air into the insulation, as this can significantly reduce the performance properties of mineral wool - the more moisture it absorbs, the more difficult it will be for it to retain heat.

It is worth remembering that the entire space of the roof does not need to be insulated, but you should take care of the so-called cold triangle. The space located at the top of the roof at a distance of 300-400 mm must be left untreated mineral wool, since this cold triangle will promote good air circulation in the attic and in the inside of the roof.

Installation of a corrugated roof is also allowed on an old roof, which meets all its operational properties, this will increase its thermal insulation properties.

The cost of corrugated roof installation primarily depends on the complexity of the structure, dimensions and, of course, on the roofing material itself.

Care of a professional flooring

In care, this roofing material is not whimsical at all. However, it should be handled with extreme care, as profile sheets can be easily damaged. Before installation, do not lay them on the ground, but rather use a special wooden stand for this, the boards of which are about 25 cm thick and arranged in 50 cm increments. At least once every six months, do a general cleaning of the roof from dirt, sheets and other "pests".

In case of scratches on the sheet, there is nothing to worry about, since the zinc layer located under the plastic will protect the corrugated board from rust, and the damage site can be treated with paint of the same color.

Each building detail or structure has a purpose. The ridge for corrugated board is designed to protect the roof from bad weather. The service life of the roof, and, consequently, the entire building, directly depends on its characteristics. This article will discuss how to properly design a roof ridge from corrugated board and install it in such a way that the roof lasts a long time and performs its functions properly for the entire period of operation.

Installation of a roof from any roofing, including metal tiles, must be carried out in such a way that ventilation of the under-roof space is carried out. Such a need is due to the fact that the air from the outside penetrates through the eaves under the roof and heats up. According to the laws of physics, it rises up and dries out the roof.

If the air that has collected wet vapors is constantly under the roof, then ideal conditions the occurrence of condensation, rust and mold, which will lead to failure of the roof. To avoid this, the air must have an exit path to the outside at the highest point of the roof. Such a place is the convergence of the upper edges of the roofing material.

Availability in top point roof cracks, makes it possible to penetrate into the attic precipitation, insects and even birds. It doesn't bode well for anything. Therefore, it is necessary to carry out the installation of the ridge of the metal tile, however, as for any other roofing materials.

Installing a ridge on a metal tile and roofs made from other roofing materials allows you to create conditions under which air freely escapes through ventilation into the atmosphere, and nothing extra gets out of it under the roof.

In addition to the practical function, the installation of a roof ridge made of metal tiles and other roofing materials allows you to give the structure a more elegant and finished look. appearance. Thus, a properly selected and correctly installed skate also has aesthetic significance.

Roof ridge from corrugated board

As a rule, the ridge on a metal tile should be made of the same material. It is not difficult to choose a ridge structure made using the same technologies as a metal tile. Most often they are sold together. Of course, you can choose the appropriate color.

As a rule, the ridge on the corrugated board is available in three variations:

ordinary corner;
semicircular;
U-shaped.

A semicircular ridge is often provided with a flat or cone-shaped end cap. In addition to the above types of skates, there are other types of section.

Often, such additional elements of the roof are produced in lengths from 2000 to 3000 millimeters. The width of the skate shelves varies from 10 to 30 centimeters. The radius of the ridge, which has a semicircular shape, can also be different.

You can buy skates in the store, but if the owner of the house wishes, it is possible to order individual production this additional roof element. In addition, if you have special equipment (a sheet bender) and certain experience, you can make a ridge roof element yourself. If this is not possible, then do not despair. Purchase finished product will cost a little more.

The ridge is a detail of the roof, which should be distinguished by good rigidity. To achieve this, manufacturers bend the edges of the shelves inward by 2-3 centimeters along the entire length of the product. This avoids damage to the ridge element of the roof during sudden gusts of wind during the execution installation work.

Construction tools and materials for mounting a ridge on a corrugated roof

The use of one form or another of a skate depends on a lot of different factors: from the aesthetic preferences of the owner of the house, and ending with the design truss system. But regardless of the shape of the ridge, its installation will require a number of additional building materials and tools that you need to prepare in advance and take with you to the roof so as not to go down from it several times. So, for installation work you will need:

a ladder equipped with L-shaped protrusions at the ends, thanks to which it will not move down the roof slope;
roofing screws. With their help, the ridge is fastened to the roof;
screwdriver or curly screwdriver. The first is preferable, since with the help of a screwdriver, everything necessary work can be done much faster;
prefabricated elements of the ridge, the number of which directly depends on the length of the roof and dimensions;
tape measure or any other measuring tool;
scissors for working with metal;
sealant.

L-shaped ledge on the stairs, as a rule, is made at an angle of 90 degrees. At the same time, the angle between the roof slopes is not always equal to this value. There is nothing wrong with this. If the angle is less than 90 degrees, then the main load falls on upper part corrugated board, which is laid on the crate, so nothing threatens this part of the roof. At the same time, if the angle is more than 90 degrees, then the end of the L-shaped protrusion can be severely damaged polymer coating roofing material. This point must be taken into account and protect the metal tile from damage. At a minimum, you need to wrap the ledge of the stairs with a cloth or any other similar material.

Particular attention should be paid to the selection of self-tapping screws. They come with a sharp end for working with wood and a drill for fastening metal structures. If the skate is attached to wood, then the self-tapping screw will still have to be drilled through the corrugated board. Therefore, one important subtlety should be taken into account. A self-tapping screw with a drill will pass through the metal and crash into a tree, while drilling a channel in it. A sharp self-tapping screw will not be able to pass through the metal, however, it will screw into the tree, pushing into it.

Thus, a sharp self-tapping screw will hold tighter, and, therefore, will allow you to fix the skate more securely. For places where strong gusts of wind are common, this can play an important role. In this regard, the device of the ridge should be carried out using sharp self-tapping screws. AT similar situation it is recommended to drill the corrugated board and only then screw in the screws.

So that the aesthetic characteristics of the corrugated roof are not violated, you should choose self-tapping screws with a head of the appropriate color. In stores selling roofing materials, you will certainly find these roof fasteners in a suitable color.

When preparing a screwdriver for work, you should not forget to equip it with a head of the required size, or better, take a spare one with you. It often happens that in the course of work, the tightening of the screwdriver loosens and may fall out.

Additionally, we should talk about the sealant, it is very important detail ridge roof construction from profiled sheet. In fact, it plays the role of a barrier for insects and small birds. In addition, it prevents the penetration of precipitation under the roof. At the same time, it can be used to create a ventilated skate, because it passes air freely.

It is important to choose the right sealant, because its shape must correspond to the profile of the profiled sheet. It should be noted that such a sealant is produced not only for skates, but also for cornices and valleys. The cornice adjoins the roof from the bottom side of the profiled sheet, and the ridge to the top. Therefore, the shape of the seal may vary. This must be taken into account when purchasing in order to select the required material.

Installing the seal is pretty easy. It is easy to cut and perfectly glued with glue, sealant or double sided tape. If you find a seal with special form failed, you can replace it with a universal self-adhesive material.

Installation of a ridge on a roof made of profiled metal sheets

Start mounting the ridge, it is required from the leeward side. You need to think about the shape of the ridge even at the stage of installing the truss system, but it is possible to make adjustments during the installation of corrugated roofing. They are expressed as follows:

if it was planned to install a conventional corner ridge, then it is required to lay the corrugated board in such a way that the dimensions of the uncovered crate are minimal. Otherwise, the middle may shift down. The greater the angle between the slopes and the distance between the edges of the corrugated board, the greater the likelihood that this will happen;
if there is a desire to use a semicircular or U-shaped ridge, then the rafter system needs to be slightly modified. How to do it? At the point of convergence of the rafters, it is required to install a board that will support the ridge, resting against it at the top;
during the installation of corrugated roofing, a wide variety of unpleasant situations can occur, for example, during the execution of work, it may turn out that the length of standard sheets of metal tiles is not enough for the upper edges of the roof to converge at a distance that makes it possible to use a corner ridge. In such a situation, you can also install a support board and purchase ridge elements of a different shape.

Most owners of private houses install a ridge on a corrugated roof on their own, because there is nothing complicated about it. This is confirmed by the video below:

Installation of a ridge on a corrugated roof must be carried out taking into account a number of rules:

before installation ridge elements on top of the roofing material, it is required to glue the sealant;
ridge elements must be stacked on top of each other with an overlap of 15-20 centimeters;
the ridge is attached to the roof with self-tapping screws every 20-30 centimeters. Fasteners need to be screwed into the top of the waves;

If there is an excess length of the ridge element, then it must be installed with the cut end inward. It is advisable to process the cut lines with a special paintwork material.

Over the years of using metal roofs, it has established itself as a durable, reliable and affordable roofing material. It is more often used for gable roofs, since sheets of thin and light metal with an extruded relief are great for do-it-yourself installation. The only thing weakness such a roof - the angle between the slopes, unprotected from moisture and blown. In order to quickly and aesthetically eliminate this defect, the installation of a type-setting metal ridge is required.

Reasons for installation

The junction between two roof slopes is called a ridge joint. No matter how ideally the installation of the roofing material is performed, small gaps and gaps remain between the sheets. Not only does it look unaesthetic, an unsealed ridge causes the following problems in the operation of a metal roof:

Penetration of moisture into the gaps between the sheets of metal. Water seeps into any, even minor gaps, penetrating under the roofing material and destroying the wooden elements of the truss system.
Blowing cold air under the roof. An unsealed ridge is an abyss into which heated air escapes from a heated house, this is a gap not only in the roof, but also in the budget, because in order to maintain optimum temperature more fuel and energy will be needed.
Ventilation problems. Mounting a stacked ridge on a metal tile will help establish effective ventilation of an attic or attic space. The air there will be fresh, without drafts.
Noise. The air, getting under the sheets of metal tiles through the ridge, circulates and is divided into streams, due to which the roofing material is deformed and makes popping sounds.

The installation of the ridge makes the appearance of the metal tile roof harmonious and complete, it will preserve the healthy state of the wood of the truss system, increasing its service life.

Assortment of skates

If before you had to think about how to equip outer corner between the slopes of the roof, now it is enough to come to hardware store and pick up a finished ridge in the color of the metal tile of the form you like. Manufacturers offer the following options:

semicircular patterns. A metal that is molded into a semi-circular shape. From the end sides, it is necessary to attach plugs to a type-setting ridge of this shape in order to close the voids into which snow, water or wind can get. The most expensive of the entire range of skates.
direct models. Made in the shape of a rectangle, it is used for hip, gable, to decorate the ridge. Fastening a rectangular profile will cost less than a semicircular one, but such a connection will look plain.
triangular patterns. They completely repeat the geometry of the angle between the slopes, so their installation does not involve the use of plugs. Most cheap way finish roofing work on the roof of metal tiles.
decorative patterns. They differ from other types of skate in their purpose. Fastening decorative elements with narrow shelves does not solve the problems with waterproofing the gap between the joints, but simply gives a neat look.

When choosing a metal ridge connection, you need to pay attention to the width of the shelves and the presence of a rim. Models without rims do not have enough rigidity to remain flat when fastened with self-tapping screws. BUT narrow shelves, the width of which is less than 150-200 mm are not able to effectively protect against the penetration of water and snow.

Seal selection

Professional roofers advise to inspect the condition of the ridge groove before starting work. If the installation of the metal tile was carried out correctly, then it should not have gaps thicker than 20 mm. Otherwise, a sealant must be used. The following types are suitable for this:

Even if the joint between the slopes seems to be even, its isolation with a sealant before starting to fasten the ridge will never be superfluous, because the lifetime of the roof and the safety of the interior decoration of the attic depend on the tightness of the joints.

Installation sequence

In order for the skate to perform the functions assigned to it, it is necessary to follow the recommended installation technology. High-altitude work is difficult to do alone, so it is better to get a couple of assistants. Installation must be carried out in the correct order:

When working with a metal tile, it is necessary to screw in the screws on the crest of its wave, use rubber compressor to isolate openings from moisture or special self-tapping screws, the rubber head of which performs the same protective functions. When performing installation, do not screw in the screws too often or rarely, find a middle ground so that the metal tile does not “excite” from an excess of fasteners and does not “clap” in windy weather with a shortage.

Mounting metal additional elements on the ridge will protect the roof from moisture ingress, save heat, however, during installation, do not forget about safety when working at height.

Video instruction

The leading load is held by the upper, horizontal roof beam, which is called the ridge. It is formed at the junction of the slopes and serves as a connecting element of the rafter group. The ridge is of two types, and if in the first case it is a beam on vertical racks, then in the second case the ridge is a run installed at the tops rafter legs.

Thus, the ridge of your roof and the choice of its design depends on the preferences of the owner of the house. You always want to get durable and solid roof, and to make it easier to decide, let's figure out the purpose of the skate and its varieties.

In this article

What is a horse for?

In addition to the correct distribution of the load, the roof ridge plays the role ventilation duct, which prevents the accumulation of moisture in the space under the roof of the structure. This air exchange does not allow the development of decay processes in the wooden elements of the roof, significantly extending their service life.

A variety of architectural solutions imply a lot of variability in their execution, but the roof ridge remains the defining strength element of the structure. This also applies to hip roofs, and more complex broken structures with displaced ridges, and the output of attic windows to the slope surface. Therefore, the choice of tool and the calculation of the material depends on the type of roof and the type of ridge, as the final element of the roof.

Types of ridge structures and types of components

We see that the ridge on the roof and the choice of its type determines the design of the rafter system, so we will consider the types of ridges, namely:

The ridge, which is mounted on vertical racks and slopes, providing a rigid structure and avoiding longitudinal vibrations under wind loads, rafters are attached to it in pairs;
Either the run, with the rafters connected, serves to stiffen the roof, and is made in the form of two boards at the top of the rafters or a beam under the rafters.

In the first case, first the skate is placed on vertical racks, and then the rafters are joined, taking into account the thickness of the subsequent installation of the crate. In the second case, the process of mounting the rafters is the initial one, and the pairing of the ridge with it will be secondary. The strength characteristics, subject to the rules of construction, are the same in both cases and the design depends on your choice.

Once you have decided on the type of coverage, you need to choose the appropriate material for the roof ridge.

This element is called a ridge bar and is of the following types:

rectangular section, the simplest in appearance;
ribbed with a stiffening unit of a U-shaped or other section;
figured profile, for the best adjoining on slopes;
semicircular bar with anti-wind caps;
conical view;
and embossed plank type.

In addition to the listed types, modern ridge components for your roof have mortise elements. Mention should also be made of conical plugs, various profiles, as well as parts ridge cover with aerators. Before installation, it is necessary to prepare the elements of the ridge, namely:

the type of ridge bar you have chosen with or without aerators;
ventilation tape along the double length of the ridge;
special fixture for a lightning rod;
roofing screws;
silicone or other sealant;
ridge seal.

All these elements require a quantitative calculation along the length of the roof with a small margin in case of unforeseen circumstances. Do not forget about the safety requirements during installation and work in protective gloves, overalls and soft shoes.

Do not work in windy weather, in order to avoid damage to the material, and to eliminate the risk of injury to strangers. You also need serviceable tools and equipment, which consist of the following kit:

building level;
a reliable ladder with a hook knot on the roof;
electric scissors and scissors for metal;
drill with drills of the required diameter;
accurate tape measure;
complete screwdriver with bits of the appropriate size.

It should be understood that the use of a grinder reduces durability roofing strip, since it violates the protective layer deposited on the surface of the material. After we learned what it is and how to choose this particular roof ridge, you need to calculate the parameters of the product and the subtleties of its installation.

The height of the skate and what does it depend on?

The calculation of the height of the ridge depends on the choice of the angle of the roof slope. It is considered optimal when it takes into account weather specific to your area. The prevailing wind rose dictates the height of the pediment, and the expected snow load in your area makes it possible to clarify the angle of the slopes.

After you have determined this value, the calculation of the height of the upper edge of the roof begins. It should be noted that the roof ridge will also depend on how you are going to use it. attic space. If it is residential, then this will lead to an inevitable increase in the height of the ridge, and the wind load on the pediment and the roof itself will be coordinated challenging task. hip roofs partially remove the atmospheric effect and are a way out of the situation, but it must be understood that with this option, the living area is reduced.

When all the circumstances are calculated, it is possible, even a complex roof, to be divided into more simple elements and calculate each separately. The material used, according to factory recommendations, implies the maximum angles of inclination of the roof at which it can be used for a long time.

If you know such an indicator as the width of the building and the angle of the roof, it is easy to calculate the height of the ridge and the length of the rafters using geometric formulas. At the same time, the specific size in a complex roof depends on the parameters of its elements. Suppose that the length of the gable roof is 6 m, and the slope angle is 40 degrees, then the height of the ridge will be 6 m / 2 x 0.86 = 2.58 m. Each section of the complex roof is calculated in the same way.

Ridge installation technology

Having finished the calculations, having carried out all the preparatory measures, we proceed to overlapping the roof with ridge elements. The most important thing should be considered the observance of safety regulations, the availability of serviceable tools, equipment and reliable stairs. It is necessary to work together. The installation process consists of a number of steps:

checking the horizontalness of the ridge beam;
reliable fastening of the ventilation tape;
installation of end wind protection elements;
alternate fastening of the extreme ridge bars;
installation between the extreme elements of the marking cord, which allows you to maintain horizontality and alignment when mounting the strips;
the overlap between the ridge strips must be at least 10 cm;
the fastening step with self-tapping screws should be 40-50 cm, in full accordance with the selected roofing material.

It is necessary to pay attention to the installation of ridge slats with aerators, which should be placed at pre-calculated points, and other slats should be docked with them. If their exact location is not critical, then we mount them sequentially, not forgetting the overlap of the planks. To quickly carry out the work, you need to have a serviceable tool at hand, including a screwdriver with replaceable batteries.

For work on a hip roof, there are mortise ridge strips. But for residential attic space, a variety of elements are used that allow you to protect joints during tie-in skylights and other complicating structural elements. wind slats, grooves and cornices will become important element roofs and will not allow atmospheric precipitation to penetrate under the roof space. Self-tapping screws should correspond in color to the selected type of ridge cover and be attached strictly at an angle of 90 degrees to the slope plane.

The rules prohibit the use construction foam when installing the roof ridge, because it is destroyed by vibration and ultraviolet radiation, and also prevents proper ventilation under the roof space. Before installing the roof, it is necessary to protect all wooden structures roofs with special impregnations to prevent rotting, mold and the harmful effects of the wood borer.

Conclusion

We hope that we have found answers to all questions about correct installation roof ridge that you were interested in. Installation of the skate, the choice of its type, the right tool, the technology of work, are covered by us in detail and very clearly.

durable, reliable roof will serve you for a long time if you follow the rules of this type of work and choose high-quality, reliable material. Let your cozy house only makes you happy.

A ridge is a horizontal rib, which is located at the very top of the roof and is attached to the corrugated board. form given element roof slope joints. The ridge system also includes other elements that are attached to the rib. It is in this place that the roof is ventilated, and the space under it is also ventilated. When installing the ridge on the corrugated board, a ridge run is also created - with its help, the slopes of the rafter system are connected.

Roof ridge

As you may have guessed, skates are elements of only those roofs that have two slopes. In roofs of irregular shape, the ridge is also used, only in this case it will be displaced.

When mounting a skate, it is especially important to consider the following two points:

Accurately calculate device height
ensure ventilation of the roofing pie from the corrugated board and the attic of the room.

Until recently, asbestos cement was used to decorate the ridge. Today, more and more preference is given to structures made of galvanized iron. You can buy them at ready-made, or you can independently engage in the manufacture of a corner.

The ridge on the corrugated board can be performed in several ways. So, sometimes it is bars that serve as supports for rafter legs. Vertical racks at the same time, they rely on beams along the ceiling or puffs.

In another version, the ridge on the corrugated board is connected by longitudinal ties along the triangle of the truss system. This option involves sewing boards on each side of the rafters. What should be used special angles. This will allow you to form a skate.

Types of ridge elements

Roofing materials act as the basis of the device. So, it can be metal profile, ceramic or bituminous. Various types of skates. So they can be represented by ridge slats, semicircular structures, they are mortise and crossed.

The ridge bar connects the docking sections. The ridge for corrugated board is also an element of decor. You can easily find elements that are ideal for you in terms of color, organically fit into the concept of the building. When installing corrugated board, be sure to install a special seal under the ridge.

The functions of a semicircular fastening for corrugated board are no different from the functions of ridge slats. However, such a device looks much more beautiful. Many manufacturers make skates different colors and invoices. At the same time, it is better to use roofing elements from one manufacturer, in which case the installation of the ridge on the profiled sheet will be of high quality.

A mortise ridge on a corrugated roof is used for hip roofs. Such details are embedded in roof slopes. Horizontal levels are always lower than the main ones. Crossed skates can also be used for these types of profiled sheet roofs.

Important Points

The device of the skate involves the observance of some very important points.

Do not make the ridge connection tight. This condition is necessary so that air can circulate in the under-roof space.
Mounting the element on a profiled sheet is always the final step. Before proceeding with the installation, it is necessary to lay ventilation material, a protective bar from moisture. As protection, a special seal for the ridge can be used.

After you decide on the material of the future roof, take care of that. To have everything at your fingertips necessary accessories(except for roofing, ridge and fasteners). So, you will definitely need a ridge ventilation bar, a ventilation tape, a lightning rod holder, hermetic material, ridge. Without these materials, you simply cannot build a solid installation and fix the ridge on the roof.

Installation of the skate on the corrugated board

Determine the ridge height

Before you start working with a ridge structure, determine the height of the element for the corrugated board. It is from this indicator that we will build on the calculation of materials. To calculate, you should have knowledge in the field of geometry. Determine the angles of the roof slope. There is a special table, you can use it for convenience. The most important thing is to know the width of the building and the magnitude of the angular slope.

Skate height calculation scheme

Let's take an example. Let's say our building has a width of 8 meters, and the required inclined angle is 40 degrees. To calculate the desired height of the structure, multiply the width of the building by a factor (0.839 times 4). So the required height will be 3.35.

Installation of ridge elements

After the installation of the roof is completed, you can proceed with the installation of the ridge element. However, before proceeding to the skate, check the evenness of the entire structure and its parts. Before fixing the ridge elements, install a special beam, the cross section of which should be at least 7x9 centimeters. Two crate bars are attached to the installed element.

The ridge beam is always attached to the central one. It is important that its upper edges are rounded, this makes it easier to work.

If you beat it before installing the ridge beam on the corrugated board, this will protect the ceiling from fungus, mold or decay, so no flaws will appear on the ridge long time and it will last for many years.

The installation of the ridge and its parts is carried out to the ridge beam with screws. To build ridge floors, two skates should be laid on adjacent slopes. The main skate is a little longer (about a centimeter), after strengthening it, proceed to install the remaining skates. At the same time, their extended ends should be directed towards the front.

Skate mount

So everything preparatory work finished. Now we will learn how to attach the skate to the profiled sheet. First we pull the string. Of course, it is better to share this stage of work with an assistant - it will be much easier for you than for yourself. The lace must be level. For convenience, you can temporarily attach it to opposite corners of the roof with self-tapping screws. If necessary, you can always lift it up.

In order for the work to be done efficiently, do not screw the screws into the corrugated board immediately. Just get all the elements. Fasten the following with an overlap of 10-20 cm. Again, we check everything by cord and level, after which it tightens other fasteners to the corrugated board.

If your roof has semicircular view, install the caps on the ridge at the ends of the element.

The ridge element on the corrugated board should be fixed very high quality, because the durability and strength of your roof, its dryness depends on it. And this, in turn, will provide a comfortable and warm environment for your home.

On a note

Holes should be drilled on both skates and on the flat side of the bar
Two more holes need to be drilled on the line of the bar hump, which is parallel to the axis.
The skate should be installed from the end
The ridge edge should protrude a couple of centimeters
If you are mounting a flat skate, make sure that the parts are clashed by at least 10 cm
A semicircular ridge involves docking along stamping lines
The places where the boards under the ridge are fixed are determined by the angle of inclination. The method of fastening also depends on this value.
The thickness of the boards under the ridge is always at least 10 cm thicker than that of the boards of the step crates
