Soft roofing materials are an excellent alternative to traditional slate and sheet metal. Roofs covered with flexible tiles are distinguished by their stylish appearance and high reliability. But you can only get both if you follow the installation technology. Of course, the easiest way is to hire a team of professional roofers, however, you can forget about the budgetary construction at the same time - at best, the work will cost the same amount as building materials. And at the same time, it is not difficult to save money - it is enough to lay the soft roof with your own hands. Today masters with many years of experience will tell you how to do it correctly.
Composite, soft or bituminous shingles, shingle roofing, shinglas, roofing tiles - all these are the names of the same building material - flexible shingles. Being flat sheets of small size (most often 100x34 cm), the shingles have curly cutouts that divide them into several petals. Laying by displacing one row relative to another gives the same effect that makes the roof look like a tiled one.
Due to the fact that soft tiles are available in a variety of shapes and colors, it is easy to choose the most suitable design option.
Today on sale you can find a soft roofing with petals of any shape - rhombic, triangular, hexagonal, oval, rectangular, in the form of a wave, etc. In addition, there are a considerable number of color solutions. And yet, despite this diversity, they all have the same layered structure and composition.
The presence of several functional layers is the key to the strength and durability of a flexible roof
The optimal size, modern technology and the use of high-quality materials give shingles a lot of advantages over other roofing materials:
In fairness, it should be noted that flexible shingles require additional costs for arranging a solid base, and are also not suitable for roofing in severe frost. But compared to the long list of benefits, these disadvantages are negligible.
Roofing cake is called a multi-layer structure, which serves as the basis for laying soft tiles. It includes some elements of the rafter system, lathing, thermal insulation, lining and moisture-proof material - it all depends on how the attic is equipped. Distinguish between a roofing cake for a warm and cold roof. The lot of the first is to create a base for shingles on outbuildings, summer cottages, garages, sheds, etc. If it is necessary to build a roof of a house intended for year-round living, then it should be made warm.
The main element of the roofing cake for warm roofs is insulation. In many ways, this determines the need for several layers that are needed for its normal functioning.
The soft roofing of residential buildings is built according to the "warm" type, therefore the roofing cake is distinguished by a large number of functional layers
The key to long-term and reliable operation of the roof is the ventilation duct, which is necessary for ventilating the under-roof space. Although, depending on the region, the structure may contain one or more layers of thermal insulation, the standard base of a warm roof is built according to the following scheme:
Most often, the construction of the roofing cake is carried out from above. In this case, the thermal insulation is laid on the rough crate and the vapor barrier. If the work on the thermal insulation of the roof is carried out from the side of the attic, then a polypropylene cord is used to support the insulation - it will not let it sag while the vapor barrier and the lower crate are installed.
When constructing a roof in the northern regions, the cross-section of the rafter legs may not be enough for the installation of thermal insulation of the required thickness. You can get out of the situation with an additional beam, which is mounted perpendicular to the rafters. At the same time, the step of installing a sparse counter-lattice is selected taking into account the width of the insulation plates - they must fit into the cells with little effort.
Since during the construction of a cold roof there is no need for insulation and related materials, the design of such a roof is noticeably simplified, and accordingly, its installation is facilitated. In general, a roofing cake should contain the following layers:
The cold roof covering should provide only high-quality waterproofing, which allows the use of a roofing cake of a simplified design.
The opinion that bituminous shingles are in themselves an excellent waterproofing material does not give the right to refuse the use of underlayment, even if it is a cold roof for an undemanding awning. On slopes less than 18 degrees, these savings often lead to moisture penetration under the soft surface. The result of a careless attitude to technology can be unattractive stains on shingles and wooden structural elements affected by fungus and mold. And if the first "only" reduces the aesthetics of the roof, then the second significantly reduces its service life.
You can refuse to use a lining carpet only on roof slopes with a steepness of more than 18 degrees, and even then only partially. It is imperative that areas such as the ridge, valleys, overhangs, exit points of ventilation or chimney pipes, as well as utility lines, must be additionally protected from moisture.
As noted above, one of the advantages of a soft roof is the ease of installation. Indeed, subject to the technology, it is quite possible for a person with minimal construction skills to build even a two-layer warm roof with his own hands. At the same time, there is practically no need for the cost of tools and equipment - everything that is required is always at hand at a real home craftsman. If you are going to lay bituminous shingles, you should prepare:
If you plan to carry out work in the winter, then you will additionally need a blowtorch (gas burner) in order to warm up the mastic. The minimum temperature at which a soft roof can be laid is minus 15 ° C. In any case, it is best to carry out construction work when the outside air temperature is 15–20 ° C. This will exclude damage to the materials and ensure a reliable bond of the adhesive layer to the underlay.
Installation of shingles can be performed even at negative temperatures, however, equipment will be needed in order to warm up the substrate and bitumen mastic
To provide the necessary rigidity to the base, when constructing a soft roof, a solid-type sheathing is used. Otherwise, the bituminous coating along with the roofing cake will sag and quickly become unusable. You should not think that plywood or OSB boards can be attached directly to the rafters and thereby save on battens. Of course, such a method is quite acceptable for the simplest structures such as a shed or a gazebo, however, when building a residential building, you cannot do without additional costs for lumber. And this is due not so much to the requirements of mechanical strength (the same boardwalk easily solves this problem), but to the need to equip the ventilation gap with a counterbeam.
In addition to solid flooring and a sparse lathing, the base structure should also include a counter beam, which ensures ventilation of the roofing cake.
So, under the shingles, it is necessary to install two layers of lathing. The first tier is laid with a wooden beam or board, and flooring made of plywood, boards, OSB or a combination of these materials is used as a solid base.
If a double solid lathing is constructed from boards, then the first layer is mounted in a row, and the elements of the boardwalk are fastened close to each other at an angle of 45 ° to the ridge. In this case, the boards of the lower tier must have a thickness of more than 25 mm and a width of 50 mm. When determining the step of their laying, the section of the lumber is taken into account. It is usually possible to exclude the possibility of bending of the boards of the upper row at intervals of 200–300 mm. Sheathing the lathing begins from the ridge, leaving a gap of at least 3 mm between the boards to eliminate the consequences of thermal deformations. Sheathing lumber must have a cross-section of at least 20 mm and a width of more than 100 mm.
Single-layer lathing can only be used when arranging roofs for undemanding structures
Installation of a double combined lathing is less time consuming, therefore it is used most often. In such a design, boards or bars are used for the lower layer, and sheet lumber is used for the upper layer. The wooden base of a cold and warm roof is made in different ways. In the first case, thermal insulation and a diffusion membrane are not installed, therefore, to assemble the frame, only a rarefied crate is needed, on top of which sheets of plywood or OSB are fixed. If insulation is required, then an additional layer of lathing in the form of a bar is used, which is stuffed along the rafters. Thanks to him, a gap is formed between the waterproofing film and the large-panel flooring.
To determine the required amount of roofing tiles, insulation and waterproofing, the same principle is used as for any other covering material. In the general case, it is necessary to calculate the squaring of all roof slopes and make allowances for trimming, waste, various allowances, etc.
Before determining the consumption of roofing materials, you will need to find the total area of all roof slopes
The easiest way is to calculate materials for gable roofs - you just need to find the doubled area of a rectangle with sides in the form of the length and width of the slope. In the simplest hip roof, the slopes form two trapezoids and a pair of triangles, so it will also be easy to calculate the total squared surface. After that, the calculation of the materials of the roofing carpet is carried out taking into account the following amendments:
Starting to calculate materials for combined roofs, it will be useful to sketch out a diagram with a detailed indication of the location of the valleys, external corners and dimensions of each structural element. A more complex structure will require additional costs for materials for the roofing cake:
Having calculated how many covering materials are needed, one should not forget about materials for arranging valleys and skates. When determining the molding of the valley carpet, it is necessary to make an amendment of no more than 1%. As for the cover for the ridge, here they take into account not only the tops of individual parts of the roof, but also each outer bend with an angle of more than 120 degrees.
For the installation of soft roofing tiles, special nails with wide heads are used. Thanks to them, the fixing area is increased, which means that the risk of damage to the shingles during installation and during operation is reduced. Manufacturers produce fasteners of two types - with notches on the rod and with a smooth rod. In the process of laying, you can use both. Experience shows that the teeth on the nails for shingles are nothing more than a marketing ploy, because when you try to pull on the edge of the petal, the material itself is more likely to break through. Pulling even the smoothest nail out of wood will be immeasurably more difficult.
Nails for soft tiles differ from conventional nails with an enlarged diameter.
Tiled nails have the following sizes:
The number of nails that will be needed for the installation of soft tiles is determined only after the number of roofing tiles has been calculated. One tile sheet is secured with at least four nails, which must be driven in at a distance of 145 mm from the bottom edge and 25 mm on each side.
Affects the consumption of fasteners and the slope of roof slopes. So, on shallow surfaces with an angle of inclination of up to 45 °, four nails per shingle will be enough. If the slope has a steepness of more than 45 °, then two more nails are used for reinforcement. Depending on the type of shingles, they are hammered in at the corners of each strip or on the attachment line drawn by the manufacturer of the roofing material. When installing the valley and lining carpet, nails are hammered along the perimeter of the strips, observing a step of 20-25 cm. The additional elements are fixed in a checkerboard pattern, placing the fasteners at a distance of 15-20 cm.
When installing shingles, it is necessary to hammer nails correctly, otherwise the coating will not last long
1 kg contains up to 400 roofing nails, which makes it possible to roughly estimate their consumption. So, for the arrangement of 100 sq. m of soft roofing will need from 8 to 10 kg of fasteners.
During the installation process, shingles of bituminous shingles have to be cut both at the edges and at the junctions, in the valleys and at the outer corners. Very often, novice roofers use a paint knife or metal scissors for cutting. Well, in the absence of an alternative, even large cutting scissors can be used. Yet none of these tools will give you the straight cut and convenience of a dedicated roofing knife for shingles. The hook blade allows for free-hand cutting and trims in place with minimal effort and an extremely clean and clean cut. By the way, an ordinary construction knife can be turned into a roofing knife in no time. All you need to do is replace the trapezoidal blade with a hook blade. You can buy the latter in building markets - most often such canvases are sold in sets of 3-5 pieces.
With a hook blade, a regular construction knife can be transformed into a specialized tool for cutting shingles
The construction of the roofing cake can be started immediately after the rafter system is ready. Preparation of the base of a soft roof consists of several stages.
To fix the vapor barrier, it is convenient to use counter-lattice slats or strips, to which the attic finish will subsequently be attached
When installing a rafter system, the step between the lags is often selected to the size of the insulation
|Step of lathing or rafters, mm||Plywood sheets, mm||OSB, mm||Board, mm|
From my own experience, I can say that the optimal board thickness is 10 mm. Such a flooring will not bend even under a powerful snow load and will provide the calculated durability of the soft roof. When choosing plywood, preference should be given to coniferous wood varieties. As practice has shown, such a flooring practically does not lend itself to deformation at temperature extremes and high humidity. For additional treatment of the surface and edges of the sheets, I use a water-repellent compound. As for OSB, the technology of their manufacture allows you not to bother with any impregnations - such material can easily withstand even small leaks. That, however, does not remove the need to timely identify and eliminate defective spots.
When laying the slabs, a deformation gap of 2 to 5 mm should be left. Otherwise, a solid base can "lead", because of which the roof will lose its visual appeal or even leak. The flooring should not reach the ridge itself - for normal ventilation of the under-roof space, a gap of at least 70 mm is required.
Arrangement of soft roofing takes place in several stages:
The work is best done in summer. The bitumen and mastic will be warmed up by the sun's rays, which will make it possible to obtain a durable monolithic connection of the roofing tile with the substrate.
Rolled bituminous materials are used as a lining for a soft roof, which are mounted both along and across the slope. To ensure the tightness of the joints, the lining is spread with an overlap of at least 10 cm along the line of the panels and 15 cm in the places of transverse abutments.
When installing the underlayment, take into account the peculiarities of the geometry of the roof to ensure maximum tightness
On roofs with steep slopes, only the zones most susceptible to leaks need waterproofing - valleys, ends and overhangs of cornices, junctions to vertical sections, ridge, etc. It is only important that the joints of adjacent surfaces are protected by a lining carpet on both sides, and its width is:
The fastening of the lining carpet is carried out with nails or construction staples, which are placed at a distance of 20-25 cm from each other. In valleys, the fastening step is reduced to 1–15 cm, and bitumen mastic is used for more reliable fixation.
Additional elements of a soft roof allow to protect the crate and other parts of the wooden roof frame from precipitation. Eaves strips (droppers) are installed on the eaves overhangs over the waterproofing and fastened in a checkerboard pattern using the same nails for a soft roof. The frequency of the nail break should be no more than 10 cm. In the joints, the metal strips are put one on top of the other by 3-5 cm. The pediment strips are fixed at the ends of the ramp in the same way. The only difference is that it is important to observe the installation direction - from the eaves to the ridge.
The edges of the soft roof are protected with cornice and pediment strips
Before installing flexible roofing tiles, horizontal markings must be applied to each slope. With it, it will be much easier to maintain the correct location of each row. You can draw a straight line using strong twine, which is previously rubbed with chalk. Having fastened the cord on both sides of the slope, it is pulled and sharply released. When struck against a substrate or wood base, the string will leave an even trail.
When laying starting shingles, it is important to make the necessary indentation from the edge of the eaves overhang
Eaves shingles are made in the form of straight shingles, not divided into separate petals. Starter strips usually sell for a higher price than regular tiles. For this reason, some craftsmen simply cut off the petals from them and attach this side outward. For fixing, standard nails with wide heads are used, which are spaced 25 mm from the edge of the tile. Each subsequent strip of eaves tile is attached end-to-end with the obligatory coating of the junction with bitumen mastic. The distance of the shingle from the edge of the eaves should be 10–20 mm.
First of all, the roofing material is mounted at the junction of adjacent slopes (if such are provided by the roof structure). For this purpose, manufacturers produce a special end carpet. When spreading, it is wound on both adjoining surfaces, glued and additionally fixed with nails.
End carpet is wound on both sides of the slopes, glued with bitumen mastic and then fixed with nails
When starting the installation of ordinary tiles, the shingles from all packages should be mixed. Thus, it will be possible to avoid a situation with an uneven color shade of the roof or the appearance of pronounced stripes of a certain tone.
Laying of ordinary tiles begins from the middle of the eaves, placing the tiles in vertical rows to the edges of the slope. The first row is mounted at a distance of 20-30 mm from the edge of the eaves tile. In order to obtain the same "tiled" pattern, the upper row is shifted relative to the lower one. In this case, the upper petals should overlap the cuts and attachment points of the lower strips.
The shingles themselves are fixed as follows:
When laying shingles, the attachment points with nails are chosen so that the next row overlaps them
The ventilation scheme of the under-roof space will be able to work only if the passage of air at the ridge of the roof is provided. For this purpose, special plastic aerators are used, which are attached to the elements of the rafter system with nails or self-tapping screws.
High-quality ventilation of the under-roof space can be provided using special aerators
Ridge shingles are obtained from cornice shingles by cutting the latter along the perforation. Individual tiles are laid across the ridge, secured on each side with two nails. In this case, each subsequent sheet is applied to the previous one by at least 5 cm, and a layer of bituminous mastic is applied to the junction.
From above, the aerator must be covered with ridge tiles, otherwise the plastic elements will suffer from atmospheric influences and solar radiation
If various engineering communications pass through the roof - antenna racks, ventilation pipes, etc. - special pass-through nodes are installed in these places. Their attachment to a solid base is performed even before the start of laying the soft roof, in order to let the shingles from above during the installation process. After that, the soft tiles are glued to the penetration with bitumen mastic, pre-cutting the shingles in place.
In the places where the slopes adjoin the walls, chimneys and brick ventilation ducts, the top layer of the roofing cake is brought onto a vertical surface. To avoid damage to the roofing at the bend, a plinth (triangular) strip is attached at the junction of the wall and roof... The lining and edges of the tile sheets are coated with bituminous mastic and carefully glued to the mating surfaces. All that remains is to protect the edge of the shingles from moisture flowing down the wall. To do this, a valley carpet is mounted on top of the roofing, onto which an abutment bar is nailed in the upper part.
The structure of the junction to the vertical surface provides reliable protection of the roof from leaks
Violations in the technology of installing bituminous tiles lead to leaks and reduce the reliability and durability of the soft roof. The most common installation errors include:
Unfortunately, it is very long to list the mistakes made by novice roofers. Meanwhile, all the nuances of installation are provided by the manufacturer and are provided in the technological map, which can be found on the official website or in the instructions for the soft roof.
As one of the most technologically advanced and durable roofing materials, flexible shingles do not tolerate carelessness and haste during work. It is possible to hope for a long service life of a tiled roof without leaks and damage only if all technology requirements are observed. During operation, it will be necessary to monitor the condition of the ventilation holes, repair damage in a timely manner, periodically clean the roof from moss and treat it with antiseptic solutions. Not that difficult task, is it?
A reliable, but at the same time inexpensive roof is a dream, perhaps, of every home owner. Such characteristics are possessed by bituminous shingles. So that in the end you get a high-quality coating, we suggest that you familiarize yourself with the technology of its installation. Having completed the installation of flexible shingles with your own hands, you will significantly save costs. High-quality styling is the key to the durability of the coating.
Installation actions consist of several stages. These include the installation of the base under the roof, then the lining layer is laid, the cornices, valleys and end parts are installed, the junction is arranged. At the final stage, flexible shingles are installed on the ridge. All these points will be described in more detail in this article.
The first layer is lining, dusting or film. The layer protects the plates from sticking during transport or storage
A pair of waterproofing layers made of bituminous mass. This ensures water resistance. Bitumen is improved by oxidation to increase wear resistance, or modified with polymers to make it more elastic and durable. The lower surface is covered with a self-adhesive layer of bitumen (stripes or dots)
The third base layer is made of bio-resistant web, usually a material such as polyester or fiberglass.This layer is placed among the insulating layers so that it provides tensile strength. Laminated shingles also have a fiberglass layer.
The surface of the tile is covered with stone chips, finishing with ceramicized granulate. The layer gives the coating a decorative effect, reflects the sun's rays, and protects the surface from mechanical damage.
If we consider the scheme of a roof structure from a soft roof, then you can pay attention to the presence ventilation gap between the steam extraction membrane and the base of the roof. Just five centimeters is enough for the air to circulate freely.
Another layer of counterbeam, which is already parallel to the rafters, helps to create a ventilation gap. Such a roof structure from a soft roof is the most optimal.
As a counter-beam, elements with a cross section of 5x5 cm are used, placing them with a distance of 30 cm. The bars are not laid end-to-end, but breaks are made by about five centimeters.
Do-it-yourself installation of a soft roof is performed as follows.
Attach the counter-beam to the crate OSB slabsmoisture resistant. Gaps of approximately four millimeters are required between the individual sheets. Height differences should not exceed two millimeters.
During the installation of a soft roof, be sure to take care of the installation drainage system... Immediately after fixing the OSB boards, hooks should be installed that will hold the gutter. Then the gutter and all other parts of the gutter are installed, including the funnel and pipes.

Further, the installation of a soft roof with your own hands involves laying on the surface wood slab waterproofing material... It is placed with overlapping seams. Longitudinal overlaps should be at least ten centimeters, and transverse - twenty. All seams are additionally sealed. To do this, they are treated with bituminous mastic.
To carry out the installation of shingles, the roof is marked. Then the material is laid and fixed with brushed nails with a galvanized surface. Installation of flexible shingles from the cornice is started. It is laid in rows, rising towards the ridge.
The next stage of installing a soft roof is laying ridge elements... So that the individual elements of the shingles lie tightly, do not rise by the wind, they are fixed with bituminous materials.
Installation of flexible shingles is being completed closing the joints and their careful isolation. It is imperative to close the junction of the roof to the pipe, walls or other elements with planks. Also, at the end of the installation of the soft roof, all additional work is carried out. Such as the installation of roof windows, snow holders, soffits on eaves and others.

When purchasing a product, you should carefully review the instructions from the manufacturer. It necessarily indicates how to lay the shingles. It is often enough to follow the step-by-step instructions to get the roofing done correctly, but getting familiar with the steps in advance helps to allocate time.
Advice! Installation of bituminous shingles requires caution: no bends, creases. Do not walk on the surface unnecessarily.
Now the mounting technology:
Advice! Before laying, the waterproofing carpet is rolled out, trimmed, then the protective film is removed and only then glued to the substrate. Additional fixation along the edges with stainless steel nails will help to secure the sheet of material more firmly. The points of joints and overlaps are additionally sealed with bitumen mastic and crimped.
Advice! When starting to lay out the shingles of the shingles, it is better to first mark the slope. Mesh markings will help place the roofing material, taking into account the alignment, joints. It is easier and smoother to make the markings with a regular painting cord.
Advice! Often sheets in bundles have some differences in color background. So that the laid shingles are not very different, you should open several packs in advance and lay out the elements alternately.
Important! It is strictly forbidden to drive in nails to the end. The cap should fix the soft tiles, but not deform / push them.
After the do-it-yourself installation of the tiles along the slopes is completed, it remains to arrange the valley and gables. Flexible roofing has a lot of advantages, one of them is the quick arrangement of the most difficult areas. The roof in the valley area is arranged as follows:
It is not difficult to lay the roofing material along the gables: the side shingles are cut with the calculation of the distance to the ribs of 10 mm. Cut the upper corner, like the end elements: obliquely 4-5 cm. Place the edges of the tiles on bitumen mastic and fix them with nails.
Installation of bituminous tiles on the ridge has its own characteristics: a gap is cut along the ridge element that does not reach the ribs of 300 mm. The installation of the shingles is carried out before the start of the slot, after which the additional element (ridge profile) is mounted. A long skate may require multiple profiles, this is normal. Fastening with nails, laying is carried out end-to-end, the interface points are coated with bitumen.
Important! On the ridge, a leeward installation is carried out. Flexible tiles are laid out against the wind, an overlap of at least 30-50 mm.
It is not difficult to mount a soft roof, especially if you observe the technological subtleties of the process, perform an accurate preliminary calculation. The works are carried out on a dry sunny day without wind and strong heat. If clarification is required, watch a video from professionals: do-it-yourself installation of flexible shingles.
Soft roofs are suitable for roofs with a slope greater than 12 °. At smaller angles, leaks may appear at the joints, therefore a lining carpet is laid under the tiles with a solid carpet - a special material that protects the roofing materials from moisture.
The main difference between a soft roof of any type is the use of a solid base or lathing with very small gaps - about 0.5 cm. The rest of the system is similar to any other: a rafter system, with hydro and wind protection, insulation located between the logs. An approximate shingle roofing cake is shown in the photo.
This is what a shingle roof cake might look like.
There are several options for arranging a base for roofing material:
Flexible shingles are not affected by fungi and mold, they do not rot or deteriorate. But it fits on wood, which is damaged by high humidity. Therefore, wood is treated with antiseptic impregnations. But to ensure its durability, a ventilation system is also needed.
For natural ventilation and drying, a gap of at least 5 mm is left between the waterproofing layer and the base under the shingles. Sometimes this requires a counter-lathing to which the base is already attached. Also, ventilation holes are made around the entire perimeter of the roof in the overhangs. To prevent birds and insects from flying in, the holes are closed with nets.
If flexible shingles are included in the roof project, do-it-yourself laying should begin with determining the number of facing, additional, consumables. Make sure that the bottom often of the roofing pie is assembled in accordance with the requirements for this coating.
Before buying the required number of shingles, slats, single carpets, skates, other additional elements, fasteners, a calculation is required to ensure a supply of materials. The approximate consumption is:
The valley carpet has a stone powder similar to shingles, abutment strips, cornice overhangs, pediment ones are made of special steel. On the websites of leading manufacturers, there are obligatory calculators for calculating the amount of materials for single, multi-slope, hip, hip, mansard roofs.
For laying the roofing material in question, a hand tool that is present in the arsenal of a home craftsman is sufficient:
For the convenience of working at a height, the shingles have a small format. They are laid from the overhang to the ridge with a ledge, so that each upper row overlaps the lower one. Endows, chimney passages, ventilation pipes are processed first. Then the cornice, pediment strips are fixed, the gutter brackets are attached. After that, it remains to fill the surfaces of the slopes with shingles, cutting them in width and length as needed.
When installing tiles on a ridge, ridge tiles are required. It is made with perforations that divide each element into 3 conventional parts. It must be laid with an overlap of 5–6 cm. This process must be carried out so that the tiles are parallel to the slope line. The short side of the tiles is parallel to the slope lines. It needs to be fastened with nails.
A roof made of flexible shingles can be installed only at a positive temperature, when the thermometer shows at least + 5 ° C. This is due to the peculiarities of the shingle (a sheet consisting of three to four tiles). It is attached to the lathing with nails or on a special self-adhesive layer. The fact is that the tightness of the soft roof is provided by solar heat. Under its influence, the sheets are glued to the base and to each other. In cold weather, this will hardly be achieved, which means that the insulation will leave the best. On the ridge, you need to overlap, and in cold weather, the shingle becomes especially fragile.
It also happens that shingles roofs are forced to be installed in winter. In such cases, the roofing material must be kept in a room with room temperature. If you still have questions on the topic, then you can get additional advice from our specialist.
