Soft roofing is an excellent replacement for traditional roofing materials. Its advantages include low weight, flexibility, low cost, as well as ease of installation.
Traditional roofing materials such as asbestos-cement slate, shingles and galvanized steel require several people to install. The construction of a roof from these materials took a lot of time.
The soft roof is devoid of these shortcomings. In the construction market, it is presented not only as a piece material, but also as a rolled one. Further in the article, we will talk about how to install a soft roof with your own hands.
Soft roofing is also sometimes called bituminous tiles, since bitumen is its basis. However, this material should not be taken lightly. It has practically nothing to do with ruberoid. Soft roofing is a durable roofing material that has a long service life. It is much stronger than traditional roll roofing materials.
Bituminous roofing is manufactured using the latest technology. Therefore, it has many advantages. Such material is resistant not only to high temperatures, but also to low ones.
Soft tile "Shinglas" is produced by the company "TechnoNIKOL". The service life of such tiles is 10 - 55 years. The roof, made of modern soft tiles, does not tear, and also does not lose its properties during temperature changes. During manufacture, all kinds of modifiers are added to the material, which increase its bending strength.
Also soft tile has the following features:
- In the process of making tiles, bitumen is melted with oxygen. Thanks to this, the melting point reached one hundred and ten degrees Celsius.
- Flexible tiles are reinforced with fiberglass. Due to this, the material becomes more durable.
- The composition of the upper layer of the material includes stone dressing. It performs a decorative and protective function.
Obviously, flexible tile is a strong and durable material. It is not at all difficult to lay and operate such a tile. However, in order to properly install a soft roof, it is necessary to carefully analyze the main stages of work.
Shingles dimensions
The soft tile is piece roofing material. Its length is 100 centimeters, and its width is 33 centimeters. The canvas is small, so the laying of this material can be done by one person.
Externally, the flexible tile looks like a classic. Each web of material is divided into four parts. Each part has the shape of a geometric figure.
It is necessary to lay this material on a pre-prepared base. For this, a continuous crate is made. As a material for the crate, as a rule, sheets of plywood are used.
Also, a “carpet” is placed under the shingles, which minimizes the negative impact on the roofing material and provides additional waterproofing.
Preparation of tools and materials
As mentioned above, the installation of a soft roof can be done alone. Before laying, it is necessary to prepare the following materials and tools:
- Mounting knife;
- Mastic;
- A hammer;
- sealant;
- End and cornice strips;
- Master OK;
- Roofing mop;
If the roofing is being laid in cold weather, a gas burner will also be required.
Soft roof insulation
The heat-insulating layer is attached from the street side. It should be noted that the first sheets must be laid between the rafters. However, before that, it is necessary to make a rough sheathing on the inside of the roof.
The optimal thickness of the thermal insulation material is 20 centimeters. Next, the counter beam is installed and another layer of heat insulator is carried out.
The waterproofing layer is overlapped parallel to the roof eaves. The overlap should be fifteen centimeters. Also, approximately 15 centimeters of waterproofing should additionally go beyond the thermal insulation contour. A construction stapler should be used to fix the membrane. Waterproofing joints are glued with self-adhesive tape.
Foundation preparation
The base for the roofing material must be extremely strong. She shouldn't bend. The base can be made from the following materials:
- OSB boards;
- Plywood;
- Tongue-and-groove boards, the width of which is 10 centimeters.
If the base is made in winter, then gaps of 3 mm must be left between the seams of the material. If the base is made of boards, then the gap should be 5 millimeters.
Arrangement of the ventilation gap
Ventilation is very important for the roof of a building. Due to it, it is possible to avoid high humidity and reduce the amount of ice accumulating on the roof during the winter months. Ventilation also lowers the temperature inside the roofing "pie" during the summer months.
The composition of high-quality ventilation includes the following elements:
- valves that provide fresh air;
- Ventilation outlet;
- Air gap. It should be between the waterproofing and the base of the roof. The gap should be 50 mm wide.
The ventilation area directly depends on the angle of the roof slope. With a roof slope of more than 25 degrees, the area of \u200b\u200bthe hole should be made 8 square centimeters. If the slope of the roofing does not exceed 25 degrees, then the opening area should be 16 square centimeters.
The importance of a liner
The lining is a special bituminous material. It is mounted around the perimeter of the entire roof.
Laying should be done from the bottom up. You need to start from the roofing cornices. During the installation of the material, an overlap of 10 centimeters is performed. As fasteners, ordinary nails are used. They should be driven in every 20 centimeters.
If the angle of the roof slope does not exceed 18 degrees, then the lining material should be fixed only on the overhangs of the cornices, the ridge, the junction with the wall and near the chimney.
If the slope of the roof does not exceed 12 degrees, then it is not advisable to lay a soft roof.
Fastening the slats
Eaves levels (droppers) fasten on eaves of a roof. They protect the material from precipitation. They can be installed directly on the gasket material. Planks are fastened with an overlap of two centimeters. Roofing nails should be used as fasteners. They are hammered in a zigzag pattern along the entire cornice plank.
Gable strips are mounted on the ends of the roof. They should also be fastened with an overlap of 2 centimeters. Nails are hammered at intervals of 10 centimeters.
After installing all the planks, the valley carpet is laid. This item greatly improves the waterproof performance. It is important to note that the color of the valley carpet must match the color of the roofing. The carpet should be fixed at the edges with nails in ten centimeter increments. Then you can lay a soft roof. Let's consider step by step the technology of installation of shingles.
Laying cornice soft tiles
Eaves tiles should be laid on planks previously installed on roof overhangs. The fixing of the roofing material is carried out by means of galvanized nails. They should be hammered into the bottom and top edge of the material. In this case, the indentation from the edges should be 25 millimeters.
To save money, you can install an ordinary one instead of a cornice tile. However, in this case, you will have to cut out the tiles. To do this, you will need to trim the shingle petals. Laying the material in such a situation is carried out end-to-end at a distance of 20 millimeters from the overhang.
Installation of an ordinary flexible tile
First of all, it should be noted that tiles may differ in color, even if they are from the same batch. Therefore, it is advisable to mix several packages of roofing material before installation.
Installation of shingles starts from the center of the roof overhang. Cloths are stacked on both sides.
It is necessary to remove the protective film from the tiles immediately before laying. Roofing material is fixed with nails (4 pieces for each shingle). If the slope of the roof is more than 45 degrees, then it is recommended to use 6 fasteners.
The edges of the first row of material should recede 10-15 millimeters from the edges of the cornice overhang. The joints between the tiles are covered with petals.
Laying the second row of shingles is carried out in the same way. However, here the petals overlap the notches of the previous one.
Exactly the same procedure is performed in the valley. First, the shingles are cut in such a way that a strip 15 centimeters wide is obtained, and then the edges are coated with glue by 7-8 centimeters.
Trimming roofing material is best done on a piece of plywood. Otherwise, you can cause damage to the layer below.
Laying ridge tiles
First of all, you need to prepare the scaffolds. They simplify the installation work with the roof ridge.
Installation of bituminous tiles is carried out with an overlap. To fix each shingle, you need to use 4 nails. The overlap of the roofing material should be approximately 5 centimeters. It is important to note that the installation of ridge tiles is carried out only after laying the ordinary.
To get a ridge tile, it is necessary to cut the eaves at the places of perforation. Then you need to bend each element and lay it in a short part along the roofing ridge.
Arrangement of passages and junctions in the roof
Roof penetrations can be made in a number of ways. You can use rubber seals if the hole diameter is small. This method is used for antennas and other communications. Passages for chimney pipes are carried out differently. Heat and expansion must be taken into account here.
First of all, a triangular-shaped rail is nailed along the perimeter of the junction of the roofing and the pipe. As a rule, a rail with a section of 5x5 cm is used for this. Then you need to glue the overlaps of the gasket material with glue and lay it.
It should be noted that the adjoining of the roof to the vertical walls is carried out in exactly the same way. There is only one difference - the triangular rail is attached along the wall.

Technology of installation of a soft roof from euroroofing material
Euroroofing material is a built-up roll material. He, like shingles, refers to a soft roof. Euroruberoid differs from shingles in that it can be used as a roofing material for a flat roof.
Base for roofing material
Euroruberoid should be laid on a solid and dry base. It must be cleaned of dirt and dust before laying the roofing. Concrete slabs or monolithic floors can serve as the basis. But for this they must have a drain and a cement-sand screed.
Also, roofing material can be welded on OSB-plates. The base prepared for laying the roof is treated with bitumen-polymer mastic. It is sold in a ready-to-use state or as a concentrate. If the euroroofing material will be laid on the old roofing, then mastic is not required.
You can find out the complete drying time of the mastic on its packaging. Do not lay roofing material ahead of time. Otherwise, the quality of the roof will suffer greatly.
Laying of roofing material should be started from the drain line (from below). This line is parallel to the slope line. For this reason, the flowing precipitation will not fall on the joints of the strips of roofing material.
Euroroofing material laying
The roll of roofing material must be unwound so that there are no folds on it. Then it needs to be tightened properly. To fix one edge of the euroruberoid, it is necessary to heat it up with a burner until the indicator film melts. Then the edge of the roofing material must be glued to the base. When the edge hardens, the unwound euroroofing material will again curl up to a fixed place.
At the next stage of installation of a soft roof, the fusing itself is performed. To do everything right, you must follow the following rules for arranging a soft roof made of euroroofing material:
- It is strictly forbidden to overheat the roofing material. Otherwise, you will need to purchase a new one. When overheated, the roofing material stops sticking.
- The finished roof surface should not have voids, black spots and places without a special protective dressing. Roofing, made with high quality, is always homogeneous.
- We should not forget about the overlap when laying euroroofing material. It must be at least 10 centimeters. As a guide, you can use a special strip applied along the entire length of the sheet of roofing material.
Particular attention should be paid to problem areas of the roof: parapets, ventilation ducts and other elements located on the roof of the building. Roofing mastic should be applied to these areas, which, after drying, has the same protective properties as roofing material.
Joints where snow can get in during the winter months should also be treated. For roofs with a large slope angle, snow retainers should be installed. To prevent ice in the winter, it is necessary to properly install drips and drainage systems.
The installation technology of a soft roof made of euroroofing material differs from the technology of laying bituminous tiles. However, in both cases, it is necessary to clean the roof from debris and foreign objects upon completion of installation work. Otherwise, the roofing material may deteriorate at the points of contact with these objects.

Summing up
Roofing from flexible tiles can be done by hand. To perform installation work, you do not need to purchase expensive equipment. All you need is normal builder's tools. Even the installation of roof aerators does not create great difficulties. The main thing in this business is to follow the safety rules.
It is best to start laying shingles in hot sunny weather. Then the shingles will fuse and create a single surface. Soft roofing will last much longer if you lay the lining material, as well as the hydro- and vapor barrier layer.
Soft roofs include bitumen-based roll materials, as well as a piece coating that externally imitates tiles. Soft roofs are widespread due to reasonable prices and the ability to do the work from and to with your own hands. Another important plus is the light weight of soft roofs, due to which the load on the rafter system and the foundation of the bath is significantly reduced.
It is worth choosing the type of soft roof, starting not only from the external design of the bath, but also from the angle of inclination of the slopes.
Roll roofs
Laying of rolled materials is most often done on flat roofs and shed roofs with a slight slope. Roofs with a large slope are usually not covered with rolled materials, since the appearance of the bath will be unpresentable.
| Material | Description |
|---|---|
| The most famous roll coating is roofing felt. It is glued to the base with bituminous mastic. The material is the most budgetary, easy to install, but the service life of roofing material does not exceed ten years. | |
| Built-up roofing felt is a material of better quality compared to its "predecessor". A layer of bitumen has already been applied to the basis of the built-up roofing material. During the installation process, the material is heated with a burner and rolled into several layers. | |
| Stekloruberoid - material with a fiberglass base, resistant to temperature extremes and UV rays. A coarse or fine fraction is applied to the surface of the material. So, for example, S-RK glass roofing material, which is laid with the top layer, has a sprinkling of a large fraction on the front side, and a fine one, similar to dust, on the wrong side. At S-RF glass roofing material, which is also laid with the top layer, the sprinkling is scaly. And sprinkling of the smallest fraction on both sides of the C-PM glass roofing material, which is laid with the bottom layer of the coating. Laying is carried out by welding or mechanical fixation of the material. The service life of roofs made of glass-ruberoid does not exceed 10-12 years. | |
| Membrane materials - the most modern of all of the above, have a much longer service life, high waterproofing properties. Membrane materials are not susceptible to climatic factors and the action of sunlight, mechanically strong, light and elastic. In addition, you can choose the shade of the material yourself. |

A rich color palette of shingles allows you to implement many design solutions, create your own unique roof design.
Flexible tile TechnoNIKOL SHINGLAS “Modern Brix”
Small size soft shingles can be installed on roofs of any configuration, including hipped roofs and domes, while the amount of waste is always minimal. Caring for a bituminous roof is not difficult - it must sometimes be cleaned of snow and accumulated fallen leaves. And roof repairs are carried out as simply and quickly as possible - you just need to remove the hardware and replace the defective element.
The top layer of shingles is a sprinkle of natural materials, such as basalt. The rough surface of the shingles allows snow to be retained on the roof and prevents its avalanche. In addition, coarse dressing provides mechanical strength to the coating.

A step-by-step guide to laying shingles
Soft shingles are laid only on a solid base, always hard, dry. As a base, it is recommended to use plywood sheets of increased moisture resistance or OSB-3 with a thickness of 11 or 12 mm (for some types of tiles, the use of plates with a thickness of 9 mm is acceptable). The recommended dimensions of the plates are 1.25 x 2.5 m.
It is also permissible to make a continuous crate of tongue-and-groove or edged boards with a relative humidity of less than 20%.
The slabs are mounted on top of the crate of the "inch" board, mounted in 100 mm increments. A prerequisite for the installation of a continuous crate is the observance of the spread, that is, at one point of the roof, 4 corners should not converge at once.
Stage 1. Before laying flexible tiles, it is necessary to fix additional elements, the first of which is a cornice strip. The element is necessary to drain water and strengthen the roof structure.
The bar is laid with an edge on the edge of a continuous crate and fixed with roofing screws. Hardware is driven in in a checkerboard pattern, observing a step of about fifteen centimeters. The overlap of the ends of adjacent planks is not more than five centimeters.
Stage 2. Lining carpets are used to provide additional tightness of the roof.
The first roll is rolled out parallel to the cornice strip, and the lower edge of the carpet should not reach 2-3 mm before the bend of the strip. The lining layer is fixed with roofing screws along the edges at the top and bottom. It is important that the carpet is laid with a slight tension to prevent the appearance of wrinkles and waves on the surface of the material.
The second row of material is laid with an overlap of the first 10 cm and fixed with nails along the upper edge, keeping the distance between them from 20 to 25 cm.
Between the canvases (in the place of overlap), a fixing mastic is applied with a spatula with a layer 1 mm thick. If the mastic is applied too thickly or previously diluted excessively with a solvent, swelling and smudges may appear on the roof.
If the lining carpet has adhesive strips along the edges, then additional mastic is not needed.
On a note! If there is a junction of slopes (valley) on the roof of the bath, then the lining carpet is first spread along the junction, and only after that the rolls are rolled out parallel to the cornice strip.
The total width of the lining carpet on the valley should not be less than 1 meter, that is, 50 cm in each direction from the junction line of the slopes. It is desirable that the lining carpet on the valley does not have joints, but if this cannot be avoided, then the layers are laid from the bottom up with an overlap of 30 cm and the junction must be smeared with mastic.
Stage 3. On top of the lining layer, gable strips are attached, which are also called wind strips. Fixation is carried out with nails. The hardware is hammered in with a hammer in a checkerboard pattern, a step of 12-15 cm. The end overlaps of the planks are 3 cm.
Stage 4. Design of valleys.
Moisture resistant plywood prices
moisture resistant plywood
Method 1. Open
A valley carpet is laid over the lining carpet.
The width of the valley carpet should also not be less than 50 cm in each direction from the axis of the slope joints. Bituminous adhesive mastic is applied to the wrong side of the carpet (strips 10 cm wide along the edges of the material).
The material is fixed around the perimeter with nails in increments of no more than 25 cm and indented from the edge of the carpet by 3 cm.
Method 2. With pruning
The design option for the valley does not involve laying a carpet. The shingles are cut and overlapped directly at the junction of the slopes.
Stage 5. You can go directly to the laying of shingles.
The first row is the starting one. A distinctive feature of the starting row shingles is the absence of slots. Whole strips are glued, stepping back from the bend of the eaves strip by 2 cm. Additionally, the shingles are fixed with twelve nails each (6 nails along the upper and lower edges).
On a note! If you have not additionally purchased bituminous shingles for the starter row, simply take a sharp mounting knife, a strip of ordinary shingles, lay it on a plank of a suitable size and cut the petals (teeth, triangles, etc., depending on the shape of the shingle cutting). Bituminous shingles with a “dragon tooth” shape can be left uncut.
Flexible tiles can be installed in all weather conditions, but if the outdoor temperature is below zero, then it is desirable to apply roofing material in small batches to the roof from a warm room.
Important! Do not forget to remove the shingles from the cardboard boxes and mix them together. So the roof covering will be more uniform in shade. You need to mix at least 5 packages at the same time.
The second row is started by moving the shingle of the second row relative to the shingle of the first row by half a petal horizontally and stepping back 2 cm from the bottom edge of the starting row.
The edge of the shingle, which will be laid on the wind bar, is cut at an angle of 45 degrees. The wind bar is smeared with mastic before laying the tiles.
The “dragon tooth” shingles are displaced by 15 cm. That is, the fastening of the lower row must be blocked by the petals of the overlying row.
If the shingle has a protective film on the back, it is removed by pulling in the direction from the top edge of the shingle to the bottom.
Some collections of tiles do not have a protective film, the shingles are simply folded into packages with the wrong side to each other. If the strips are difficult to unstick, they can be slightly warmed up with a building hair dryer and gently bent in different directions.
Nails for fastening tiles are galvanized with wide caps, the length of the hardware is 30-45 mm, the thickness is 3 mm. Hardware is hammered in a strictly defined order, which is recommended by the manufacturer, depending on the shape of the shingles and the angle of the roof. The greater the angle of inclination of the roof, the more nails are used to fix the coating.
Schemes of the location of hardware depending on the angle of the slope
It is important to drive the nails perpendicular to the shingle so that the head is flush with the roofing material, not too deep into it, but not above the surface of the shingle.
The nails of the overlying row must simultaneously fix the underlying shingles. This is necessary for the durability and reliability of the roofing.
Tiles are laid on top of the valley carpet by cutting the corners of the shingles and smearing the wrong side with bituminous mastic. It is recommended to drive nails into the shingles at a distance of 30 cm from the central axis of the valley.
Stage 6. When the bituminous tiles are laid to the very ridge, they proceed to the design of the junction with the pipe.
Be sure to keep in mind that walking in shoes on the laid roofing in hot sunny weather, as well as negative air temperatures, is prohibited. Scaffolding and other devices are used to move along the roof.
The junction is made using a valley carpet.
- A pattern for the front side of the pipe is cut out of the strip (the tile should be covered with a carpet by 20 cm, and the material should go 30 cm onto the pipe). A thin layer of adhesive mastic is applied to the reverse side of the pattern with a spatula. The pattern is pressed tightly and smoothed so that there are no bubbles and irregularities.
- Next, the right and left patterns are cut out, smeared with mastic, glued in place, leading the edges under ordinary tiles.
- Lastly, the back of the pipe is closed, the canvas along the upper edge is fixed with metal strips.
If the pipe is more than 50 cm wide, it is recommended to make a slope behind its back wall to prevent rainwater from stagnating.
Instead of a valley carpet, the junction can be made using metal elements.
Video - Finishing the chimney
Stage 7. To decorate the ridge, ridge-cornice tiles are used.
Each shingle is cut into 3 pieces before installation. Ridge elements are laid from the bottom up (for hipped roofs) and fastened with four nails in the corners. The overlap of the elements is 3-5 cm, sufficient to make the heads of the clogged hardware invisible.
It is recommended to lay an aerator on a ridge with a slit 3-8 cm wide and located horizontally.
This is a plastic element necessary to ensure ventilation of the under-roof space.
Each element is bent along the central axis, applied to the ridge of the roof and fixed with nails, which are driven through the factory holes of the element. The connection of adjacent elements is carried out similarly to the designer, by snapping the existing fasteners.
The laying of tiles on top of the aerator is carried out, taking into account the direction of the prevailing wind direction for the area.
They begin to fasten the ridge-cornice tiles from the side where the wind most often blows. Fixation of the roofing material is performed using roofing nails of increased length.

How to arrange the junction of the bath porch canopy to the facade?
If the roof adjoins the wall (this may include the adjoining of the bath roof to the wall of a residential building), regardless of its shape, it is necessary to waterproof the joint using a valley carpet.
Procedure:
- put the lining carpet on the wall by 5 cm, smear with fixing mastic from the wrong side, press firmly;
- if the adjoining roof is located at an angle, then in the lower part, fix a plastic wall-turning flashing with self-tapping screws. If the connection is horizontal, the tide is not installed;
- lay the valley carpet in such a way that it goes 30 cm onto the wall, and 20 cm onto the lining carpet;
- smear the valley carpet on the reverse side with mastic, glue and level so that there are no bubbles or folds;
- fix the upper edge of the valley carpet with a metal rail with holes into which screws are screwed;
- lay flexible shingles, smearing the edges of the shingles with fixing mastic (at least 10 cm from the edge).

How to move along the slope of the roof during the installation of the coating?
For safe and convenient work at height, scaffold brackets are installed. The brackets have holes through which nails are driven in for fixing. A board is laid on top of the bracket, which is fixed with self-tapping screws. The length of the board is chosen so that the free ends extend beyond the brackets by at least 150 mm and not more than 300 mm. The cross section of boards for working on the roof is 200 x 40 mm.
The upper part of the bracket is installed under the petals of bituminous tiles. For fastening, it is recommended to use nails 10 cm long and 5 mm thick, 3 nails for each element. The nails must be driven through the battens into the rafters.
One bracket can withstand 140 kg. The distance between the brackets should be no more than one and a half meters (only one roofer can be on these one and a half meters).
To remove the brackets, you simply need to bend the tabs of the shingles and pull out the nails, then put the shingles back in place and fix them again. Brackets must be lowered from the roof carefully, without dropping them down.
Important! Walking on wet, icy boards is prohibited. Working on a roof in extreme heat or cold is strongly discouraged.
How to install a roof penetration?
Roof penetrations are installed to pass ventilation pipes and antennas through the roof.
General installation principle:
- on the roofing make markings for the installation site of the element;
- shingles are cut according to the markup, the cut out part is removed;
- in the crate, a hole is cut to fit the size of the passage element;
- if necessary, the hole is closed with a fine mesh;
- the penetration contour is lubricated with fixing mastic and pressed to the installation site;
- screws are screwed into the holes of the element contour;
- install the upper penetration element.
There are also penetrations that are mounted with a slight difference - the edge of the passage element is closed with tile petals, smeared with bitumen from the wrong side.

What snow retainers to install on a soft roof?
To prevent uncontrolled snowfall from a soft roof, the simplest snow stops are installed in the form of corners on a long leg. Snow guards are metal and plastic, it is recommended to opt for the former because of their greater durability.
The installation of snow stops is carried out simultaneously with the laying of shingles. The hooks are fastened with self-tapping screws to the crate, treating the attachment point with mastic. From above, the leg of the snow retainer is closed with bituminous tile petals.
The distance between the corners is approximately 60 cm. The minimum number of rows of snow stops is 3. On steep roofs, it is advisable to increase the number of rows or even fix the corners over the entire slope area.
How to take care of your roof
Care instructions are very simple:
- it is necessary to periodically visually inspect the coating;
- snow removal from the roof is carried out with a wooden shovel. Moreover, not all the snow needs to be removed, a layer about 10 cm thick should remain on the roof;
- it is necessary to clean the gutters and pipes in time, eliminate blockages;
- if moss or lichen began to grow on the roof, it is removed, and an antiseptic with an algicidal composition is applied to the coating.
Manufacturers of soft tiles usually provide a guarantee of at least 10 years for the coating. The coating is ideal for both hot southern regions and cold northern ones. The coating is environmentally friendly, does not require maintenance, ideal for any facade of the bath. Soft roof - a great solution for baths and saunas!
In recent years, the arrangement of the roof using a soft coating has become increasingly popular, since this material has a lot of advantages. In addition to excellent operational and technical qualities, such a roof can be mounted by hand, without the involvement of experienced craftsmen.
The soft tile has a small weight, an attractive appearance, a high degree of tightness, a long service life, and a low price. It can be laid on roofs of various configurations. On the surface of such a roof, raindrops do not knock - only a quiet rustling is heard.
Features of soft tiles
The basis of this modern roof covering is fiberglass sheets impregnated on both sides with rubber bitumen, which is characterized by moisture resistance and tightness. Thanks to the above properties, the installation of soft tile roofs has become so popular.
The presence of a special dressing at the flexible roof enhances wear resistance and prevents rolled products from sticking together. has established itself as an ideal coating for structures, if their angle of inclination is not less than 11 degrees.
Tools for installation of a flexible roof
If desired, a home craftsman can do the work on arranging a soft roof alone. In this case, the maximum slope of the slopes is not limited.
Before laying a soft roof, you need to prepare:
- a hammer;
- trowel for working with mastic;
- durable gloves;
- eaves and end strips;
- ridge-cornice strip;
- roofing nails;
- waterproofing carpet;
- sealant;
- mastic.
Arrangement of the ventilation system
This system is intended to ensure the circulation of air masses, which is required to prevent the formation of condensate at the bottom of the base of the roof structure. If the ventilation device is neglected, after a while the wooden rafters will begin to rot, and in the cold season, frost and icicles will become a permanent phenomenon.
Its constituent elements are: a base with a thickness of at least 5 millimeters, air gaps between it and the waterproofing layer, vents and outlets. When creating natural ventilation, special holes are arranged, placing them evenly.
How to install underlayment
For the manufacture of cornice strips, metal is used. These elements serve as protection for the edge of the crate. Installation of the cornice plank of soft tiles on the overhangs of the cornices is carried out on a lining. Gable strips are also made of metal, which are fixed at the ends of the roof.
The valley carpet serves for additional protection of the roof from atmospheric precipitation. This material is selected taking into account the color scheme of the flexible tile. In places where leaks most often occur, and these are overhangs of cornices, valleys, end parts of the roof, it is advisable to lay a lining layer.
At the same time, installation is carried out in a certain direction - from the bottom up, and an overlap is observed, equal to 10 centimeters in the transverse direction, and 15 centimeters in the longitudinal direction. The joints of the canvases are usually lubricated with bituminous mastic.
Skates and valleys should be strengthened by 25 and 50 centimeters, respectively. At the same time, a lining layer is mounted on the valleys on both sides, and along the cornice overhangs and ends it is laid to a width of at least 40 centimeters.
The lining should be nailed to the base using galvanized roofing nails at 20 cm intervals.
Preparatory stage before laying
Starts with preparation. The base on which the flexible tile is to be mounted should be made solid. Since soft tiles do not have sufficient rigidity, it requires the arrangement of a strong crate. For the base, you can use moisture-resistant plywood with a thickness of 9 millimeters or more, OSB, edged or tongue-and-groove boards.
Material for the crate should be purchased in the winter and used in the summer. In this case, the width of the boards should not exceed 100 millimeters. It is better when the base material has the same thickness. The moisture content of lumber should be a maximum of 20%. The planks are laid apart, observing a gap of 10 millimeters.
Roofing cake should be done with the following layers:
- waterproofing laid on the rafters;
- thermal insulation from mineral wool, if it is planned to equip the attic;
- roofing waterproofing carpet, mounted on the outside of the base with an overlap.
The nuances of installing flexible tiles
There is a certain technique on how to properly lay a soft roof if the work is done independently:
- First of all, this requires dry weather, in which the ambient temperature does not fall below plus 5 degrees. If, nevertheless, the installation is carried out in winter, the tiles are kept indoors at room temperature before installation begins. You can also use a hot air burner.
- To the surface of shingles - a sheet of soft roofing from several tiles - is fixed with nails or due to the self-adhesive layer available on the back of the tiles. Under the action of sunlight, the sheets begin to solder both with the base and one with the other. If the temperature is below zero outside, this process does not occur and, accordingly, the insulation does not turn out to be of high quality.
- Tiles should be used immediately from 5-6 packages, choosing one shingle one at a time in order to avoid significant differences in shades when it becomes necessary to restore the roof with products from another product lot.
The choice of bitumen-polymer composition
Before a soft roof is laid, a mastic is selected that will allow you to create a continuous elastic surface that can withstand various types of impacts on the base. According to the technology of laying a flexible roofing surface, hot and cold mastics must be used to mount the rolled material on the roof.
Cold bitumen-polymer compositions are used to equip the inner layers of the roof structure, and hot - as an external coating. Cold mastics include bitumen and roofing material, and hot - only and tar.
The process of preparing bituminous mastic
Mastic can be purchased at the store, ready to use, or you can make it yourself. This will require bitumen, which is approximately 80% of the composition, and a filler. Take 2 parts of bitumen and 1 part of filler, resulting in a cold mixture. Bitumen is heated to 180 degrees and at the same time diesel fuel and filler are prepared. The contents of the two boilers are mixed after the water has evaporated in the bitumen.
To prepare hot mastic in a boiler, the bitumen is first heated to 200 degrees, and then the filler is slowly added to it. During the process, the temperature of the mixture should not be less than 160 degrees.
Soft roof technology
When a soft roof is laid, the step-by-step instructions from the manufacturer will tell the home craftsman how to do it:
- Before proceeding with the installation, the wooden surface is treated with a mixture of bitumen and diesel fuel.
- Next, the base is slowly covered with mastic, glassine and roofing material are laid. The work is performed, starting from the middle of the eaves and moving towards the ends. Before installing soft shingles, the film that protects the adhesive side of the roofing material is removed from the shingles.
- After applying a layer of cold mastic, wait 12 hours and cover the base with another layer. When hot mastic is used, the layers can be arranged one after the other. Each tile is nailed with 4 - 6 nails.
- When laying rolls, an overlap of 7–10 centimeters wide must be observed. Each subsequent upper row is positioned so that the mounting joints of the previous one are closed. In this case, the new layer being laid is displaced.
- Excess material is cut off along the edges of the slopes.
How to properly lay shingles around ventilation pipes
Joints near pipes or antennas need insulation and careful fastening of coating materials. Installation can be done easily, but with the use of through elements. Without these components, there will be no tightness of the coating. Before laying a flexible roof, it is necessary to mark the places where ventilation and pipes are planned to be placed.
Then you need to create holes, and then glue the edges of the lining material around them using mastic. The upper surface of the carpet, in accordance with the contour of the elements, is smeared with a mixture, glued and fixed with nails. Tiles are placed on top of the mastic. Places of joining the upper part of the passage element with flexible tiles, experts recommend treating with special sealants.
When the process is brought to the ridge line, the installation of a soft roof involves the use of ridge elements that need to be bent over it, fixed with mastic and secured with nails.
Soft roof repair
How often it will be necessary to carry out repair work on the roof depends on the condition of the base on which the tiles are being installed. Cement screed, wooden lumber elements react differently to roofing - the nature of the damage depends on this.
First of all, determine the need for repair of the roof. To do this, assess the degree of damage. If there are holes in the roll coating, they need to be filled with mastic. Repair work on the roof of this type is carried out on a cleared area.
Since the roll material is coated with a special coating, the surface to be restored must be thoroughly cleaned. The crumb can be removed with process oil. Anthracene oil is used to clean the roofing felts, and solar oil applied to a rag or brush is used for roofing material. As a result, the topping will be removed and the surface will be softened, which is important for further repairs.
Then go to the main stage. In case of minor defects, it will be enough to apply a patch and ordinary mastic. But this method is not suitable when all layers of the coating are pierced.
When simultaneous damage to several layers is found on the roof, this area is cleaned of old mastic and accumulated dirt, then dried. Then proceed to the preparation of the mastic mixture, to which sand or sawdust is added.
The resulting composition putty all the places of damage so as to align their edges. Mastic should extend beyond the repaired area by at least 10 centimeters. Using hard brushes and brushes, the mixture can be applied even to hard-to-reach places.
If repair work is carried out on a small area, then it will be enough to use a conventional spatula. When air bubbles appear in the roofing, the repair is carried out in the same way as it was done with a conventional hole. The main thing is the timely detection of leaks.
If cracks appear in the roof covering material, it must be cut down to the bottom layer. Then they clean the place of damage from debris and mastic, dry it and fill it with new mastic. When the cracks are small, they can not be cut, but eliminated with a patch and mastic.
If small cracks appear on a large section of the roofing surface, it is prepared for repair and covered with heated mastic.
After the restoration of the integrity of the soft roof is completed, it is necessary to renew the layer of dressing in order to prevent overheating of the material and, as a result, the melting of the mastic. To do this, first smooth the surface and cover it with sand. The topping which has not stuck to a roof will be removed in due course independently.
In order to carry out installation work on your own without problems, you need to follow the manufacturer's instructions explaining how to properly lay flexible tiles. You should also follow the recommendations regarding the selection and preparation of mastic. Then the soft roof will last a long time, while maintaining its tightness.
Due to its resistance to moisture and good strength, soft roofing will provide an airtight coating for any structure.
To figure out how to lay a soft roof, let's take a closer look at this material, find out the existing varieties and nuances of installation.
The soft roof is produced on modern equipment in accordance with the certificate, which indicates its high quality. The material is divided into several types:
- roll coating
- membrane
- shingles
- roofing mastic
Roll coating is divided into roofing material and rubemast. The structure of the material consists of a fiberglass base (rubemast) or roofing paper (roofing material) impregnated with bitumen.
The front side is covered with a layer of basalt chips, which protects the bitumen from the effects of negative weather factors.
Sometimes quartz sand or granite chips are used for a protective coating.
Due to the use of crumbs of different colors, the roofing becomes colored.
The service life of roofing felt is 5 years, rubemast is more than 20 years.
The membrane is produced in several types: PVC, TPO, EPDM.
The large width of the material allows covering large buildings with a minimum number of seams. You can lay the membrane all year round, regardless of weather conditions.
The service life of a membrane roof is about 50 years.
Bitumen shingles are small pieces of sheets cut from a bituminous roll. Tiles are carved on each sheet in the form of different geometric shapes.
The structure of the tile is similar to rubemast. The service life is estimated at 15 - 20 years.
Roofing mastics are bituminous, polymeric and bitumen-polymeric. In turn, they are divided into hot and cold. A roof filled with hot mastic is called mastic and is characterized by rapid solidification.
Roofing from cold mastic is called self-leveling. The mastic goes on sale to the consumer ready for use - one-component or consisting of two compositions - two-component. These formulations are mixed before use.
Material advantages
To get a closer look at the characteristics of the roof, let's look at its advantages:
- The material is adapted to sudden temperature changes (except roofing material) from +50 o C to -60 o C. The ability to endure cold and heat allows it to be used in any regions with a specific climate. Some species are used even in the far north.
- Resistance to mechanical stress allows you to withstand the blows of hail and branches from trees that have fallen on the roof.
- The use of mastic allows you to equip a monolithic roof without seams.
- The membrane completely replaces the moisture-proof coating laid on the roof insulation. The device of one hundred percent waterproofing allows you to save on the purchase of additional materials in this direction.
- Roof installation technology is simple. Depending on the type of material, it differs in the specifics of laying.
- The flexible structure of the roof allows it to be laid on domes and roofs of complex structures.
- During installation, up to 5% of material waste remains, which is impossible when using a solid roof.
- High sound insulation absorbs the noise of hail and heavy rain.
- Different colors and shapes of bituminous tiles allow you to equip original roofs.
The nuances of arranging joints
During the laying of the roof (except for mastic), joints are subjected to the main load.
The butt joint device consists of two pieces.
When arranging the roof, laying begins precisely from it.
Work with joints must be carried out in accordance with technical requirements.
Installation instructions are included with the soft roof kit.
The duration of the service life of the coating depends on its observance.
Butt joints of the roll coating and the membrane are glued or welded seams of two sheets.
To increase strength and create tightness, the sheets are overlapped. After gluing sheets of roll coating, the seam is covered with crumbs.
Bitumen shingle roofing is used to cover mansards, towers and other complex roof structures. When arranging the roof, the main joints are obtained:
- At the place of installation of the cornice strip and the first sheet
- When laying the ridge strip
- At the junction with each top row
- The shingle (single tile) is glued by means of a self-adhesive bottom surface. For the strength of the joints, each shingle is nailed with an overlap with the next tile.
The basis for a soft roof
The quality of installation of a soft roof depends on the prepared base. The optimal base device is chipboard, a flat concrete surface, a smooth board, OSB.
To achieve a smooth surface of the concrete roof, a screed is made with a slope under the water stack. For better adhesion of concrete with bituminous mastic, it is treated with a primer.
If the roof is made of a solid board, all slots and holes are caulked. Before installing the roofing material, the remains of the old coating, dirt and dust must be removed from the surface of the base.
When reviewing the roofing material, attention should be paid to the lining layer. For it, sheets without crumbs are used. The lining is laid with the first layer from the bottom of the roof in an upward direction.
Longer roof life increases the ventilated space of trussed roofs. For this, an aerator is used, which provides ventilation under the roof.
Installation technology of rolled roofing and tiles
The technology of laying bituminous roofing requires minimal heating of the surface of the material by sunlight. Severe overheating can cause unexpected bonding of the sheets to each other, which will complicate the installation work.
In such conditions, bitumen sticks together better. Let's look at how to lay a soft roof on a tile and roll roof.
Starting work with roofing material, you need to pay attention to its marking. The letter "P" in the designation indicates that this is a lining roofing material without crumbs. It is laid in the first layer. The letter "K" means that the roofing material is roofing. It is laid on top.
The following letters in the designation of roofing felt after the letter "K" indicate the type of stone chips used for the top coating of the material.
We calculate the layers of coating and choose the mastic
In order for a roofing material to be durable, it is necessary to correctly calculate the number of layers. There is a rule that the smaller the angle of inclination of the roof, the more layers will need to be laid roofing material.

How to cover the roof with a soft roof
Soft roofing, which is also called flexible roofing, shingles or shingles, is a fairly popular roofing material that has an original appearance, high waterproofing characteristics and affordability. When installing various structures, many are wondering how to cover the roof with a soft roof on their own? Installation of a soft roof does not require expensive equipment and any special skills, and therefore any home master can handle it.
Before you start laying the roof, you should prepare the necessary tool in advance, which should consist of a regular hacksaw, tape measure, hammer, pencil, sharp knife and a coil of chalk rope.
The next stage is preparatory work. Laying a soft roof must be done only on a cleaned roof surface, which must still be dried and leveled. Before you start laying a soft roof, you must make sure that the minimum roof angle is at least 11 degrees, if this angle is less, then you should change the roof structure to the desired slope.
The entire process of installing a soft roof can be divided into three main stages, such as laying the first sheet and cornice row, laying the remaining rows and installing ridge sheets. At the same time, before proceeding with the first stage of laying the first sheet, it is necessary to lay a valley carpet on the roof along the roof ridge, thereby achieving better waterproofing of the entire structure.
It is better to start installing the first sheet at the eaves, for which the first sheet is laid along it, from which the protective film is removed. The sheet should be laid 2 cm above the cornice bend, after which the next sheet is placed, butt to the first, and each sheet is nailed at the perforation site. This is how the entire cornice row is laid.
Next, we proceed to laying the remaining rows, while everything is done according to the principle - remove the protective film from the sheet and glue it towards the end parts, not forgetting to nail the sheet with nails - 4, if your roof slope is less than 24 degrees and 6, if it is more than 24°. Be sure to make sure that the lower edge of the first row of the roof is at a distance of 10 mm from the lower edge of the cornice row.
Subsequent sheets are laid on the same level with the petals of the first, and the end edges are cut off and glued with mastic, and it is desirable to coat all the nodes of the soft roof with it, which improves the sealing of the roof.
Having laid the last row, we proceed to the last stage - the installation of ridge sheets, which are obtained by dividing the cornice tiles into three parts. The divided sheet should be glued, and the short side of the sheet should be parallel to the ridge, after which the sheet is nailed on both sides with 2 nails, which should be under the next sheet, which is laid in an overlap.

How to cover the roof with soft tiles: step-by-step installation from the base
Flexible soft tiles - ideal for roofing houses with a complex roof shape. If you choose the right quality material and correctly install it on the roof of the building, it will provide the roof with high performance for many years. It is also important that when using flexible tiles, there is almost no waste left.
Soft tiles can be laid on the roof of almost any complexity and angle of inclination of 12°-90°. This material is distinguished by low weight, noiselessness and aesthetics (has a wide choice of shades and textures), durability and reliability, high water resistance and anti-avalanche properties.
Installation of a roof from a soft tile takes place in several stages:
Before covering the roof with soft (flexible) tiles, carefully prepare the base for its installation. The foundation must meet certain conditions:
- be rigid and even, for example, OSB boards, moisture-resistant plywood, edged or tongue-and-groove boards can act as a base;
- be dry (humidity not more than 20%) and ventilated;
- the base boards must be at least twice as long as the span between the supports, their maximum width is 15 cm;
- the joints between the laid boards must necessarily fall on the supports;
- a sufficient gap is left between the boards (about 5 mm) with the allowance for the possible expansion of the base material with changes in temperature and humidity;
- boards are recommended to be laid with the core up;
- if it is known that plywood will be the material for the base, then the distance between the rafters is selected in such a way that the seams of its sheets fall exactly on them.
The finished base is pre-impregnated with antifungal and fire retardant agents. To properly cover the roof with soft tiles, it is necessary to provide ventilation on the roof.
The ventilation device is a mandatory and very important point so that the installation of a roof made of soft tiles is carried out without errors and shortcomings. It is necessary in order to:
- remove excess moisture from subroofing (battens, insulation) and roofing materials;
- in summer, reduce the temperature inside the roof structure;
- ventilate the building
- prevent ice and icicles from freezing on the roof.
For the optimal solution of these problems, ventilation must be provided with a fairly large gap (more than 5 cm). At the same time, the exhaust ventilation opening on the roof should be located as high as possible in its upper part, and the inlet - in the lower part.
A lining reinforcing layer is laid under the soft tiles. If the roof is sloping (slope less than 1:3), then according to the flexible roof installation technology, the entire roof area is covered with a lining layer. In the case of a steeper roof, it is enough to install the lining layer in the end parts, in the valleys, on the cornice overhangs, on the skates. The material is laid in layers with an overlap of 10 cm from the bottom up. The edges of the material are fixed to the base of the roof with nails (20 cm step), the joints are sealed.
On cornice overhangs, rain moisture can penetrate to the edge of the batten. For protection, droppers (metal cornice strips) are laid on the lining carpet with an overlap (starting from 2 cm), which are nailed in a zigzag pattern in 10 cm increments.
End protection. The protection of the end parts of the crate is equipped similarly to the cornice with the help of metal gable strips.
To increase the water resistance of the roof in the valleys, a valley carpet is installed on the lining layer to match the tiles. The edges are securely fixed with roofing nails (10 cm step).
How to cover the roof with soft tiles? Work on the installation of tiles begins from the center of the cornice overhang of the roof in the direction of the end edges. In the first row, the tiles are laid indented from the edge of the eaves (3-5 cm). The protruding elements must cover the joints formed between the tiles of the eaves. The protective film is removed from the tile tiles and they are glued to the base, after which they are nailed over the groove line with nails.
The subsequent rows are laid with the ends of the tongues, corresponding to the level of the cutout of the tiles of the previous row. The tiles in the valleys and on the end sections of the roof are cut to the shape of the edge, then glued along the cut with K-36 glue
Processing elements of a soft tiled roof
Small roof elements are treated with rubber seals and K-36 sealing adhesive.
In places where vertical penetrations are attached to the roof, a triangular rail is nailed. On it, the tiles are brought to the surface of the roof element and glued with glue.
The junction is pasted over with a strip of Pintari valley carpet, covered with a metal apron and sealed with K-36 glue.
Similarly, sections are mounted where vertical walls adjoin.
When installing the ridge, ridge tiles are used: the tiles are glued with the short side parallel to the ridge, then the next layer of roofing is nailed to it under overlapping nails.
Construction of houses
Surely, you have repeatedly noticed that many private houses are covered with flexible tiles, a noble, solid and aesthetically attractive roofing material. You can equip such a roof, because you can lay this coating on a roof of any complexity, the slope of which reaches 12 - 90 degrees. Bitumen is very light, which makes it easy to install a soft roof with your own hands. Today we will talk about how to cover the roof with soft tiles.
Calculation of shingles
Before buying a soft tile, it is necessary to take into account that the price of a soft roof will depend on the coverage area and the number of additional elements. A feature of the material that is used to organize the roof is to minimize waste during work. It is this factor that allows you to accurately calculate the roof and calculate the required amount of base material.
Let's give an example of calculating the amount of flexible tiles. So, let the gable roof have the following parameters: the length is 6 meters, the height is 4 meters; tilt angle - 32 degrees. Then the total area is 48 square meters (4*6*2). Keep in mind that one package of shingles is enough for 3 square meters. But be careful, as the area covered is indicated on each package. Then you will need 16 packs (48/3).
Similarly, you can calculate the amount of required lining material and valley carpet. It should be noted that the technology of covering the roof with soft tiles is such that there will always be cut parts and waste. Therefore, feel free to add another 10-15% to the calculated amount. After buying a soft tile, it is necessary to store it in a warm, dry, shady place, folding no more than 12 packs one by one.
Installing a roof sheathing
To lay the bituminous tiles correctly, it is necessary to properly prepare the base. A soft roof can be laid on an ordinary crate, which can be lattice or solid and is attached to the rafters. The frame is most often made of wood. If you need to arrange a lattice crate, then take boards for this.
In this case, it is desirable to use planed coniferous boards, which have a thickness of about 20-25 millimeters. To create a solid crate, you can use moisture-resistant plywood or chipboard, grooved and edged boards. The moisture content of the material should not exceed 20% of the dry weight. The material is attached to the rafters using ordinary nails or self-tapping screws.
To increase the service life of wooden elements, they must be impregnated with an antiseptic before installation. When creating a crate, calculate in advance the installation step of the rafters and the thickness of the board used for its construction. If the step is 60 centimeters, then you can use a board that has a thickness of 20 millimeters. With a rafter pitch of 90 centimeters, a board with a thickness of approximately 23 millimeters is required.
The joints of the boards must be placed in the places of the supports, and the boards must have a length of at least 2 spans between the supports. When laying the sheathing under a soft roof, it must be remembered that it is worth leaving a couple of millimeters between the individual materials to compensate for the expansion of the wood when it dries.
On the crate between the boards, a gap of 1-5 millimeters is made, between large-panel elements - 1-3 millimeters. Plywood and slabs are laid on the rafters with a spaced seam. You can not leave such gaps if all the wood has been previously subjected to technical drying.
Underlay installation
After arranging the crate under the soft roof, it is necessary to lay the lining layer, the main purpose of which lies in protecting the house from moisture ingress in case of possible leakage of flexible tiles. According to current standards, if the angle of inclination of the roof is 18 degrees or a little more, then waterproofing can only be arranged parallel to the end and cornice edges. It is these areas that are considered the most likely places for leaks.
Things will be different if the roof has a smaller slope angle - from 12 to 18 degrees. The installation technology of such a waterproofing layer provides for its installation over the entire roof area. This layer is mounted parallel to the cornice overhang from the bottom up with an overlap of at least 10 centimeters for transverse seams and at least 15 centimeters for longitudinal ones, fixing the edges with nails at intervals of about 20 centimeters. The seams must be sealed with glue.
To protect the edges of the frame structure of the roof under soft tiles on the eaves overhangs from moisture, metal cornice strips called “droppers” with an overlap of at least 2 centimeters should be mounted over the lining carpet. They are nailed in a zigzag manner with special roofing nails, maintaining a step of 100 millimeters. To protect the lathing on the end parts, gable strips are mounted with the same overlap of 2 centimeters. The strips are stuffed on the cornices and ends over the lining layer.
If the design has elements such as valleys, then it is necessary to lay a special carpet that matches the color of the tiles on both sides. The edges should be fixed with roofing nails, maintaining an interval of 100 millimeters. After fixing, it will not be superfluous to coat the carpet along the edge with bituminous mastic.
Ventilation space device
Without sufficient ventilation in the attic, the microclimate will be disturbed, humidity will increase and condensation will form. Ventilation is ensured by three elements: channels above the thermal insulation, a hole that serves for the inflow of outside air and exhaust holes, which are located in the upper part of the roof.
If the cornices in a residential building are hemmed with siding, then the soffit strips will act as a ventilation gap.
If, when constructing a roof for a soft roof, the cornice is made out with a clapboard, then it is customary to equip a gap between the boards. Ventilation of a roof made of flexible tiles is carried out by means of a ridge, which is customarily laid on a special ribbed profile. But often its throughput is not enough and it is necessary to install special ventilation elements on the roof surface.
If the roof slope is 15 - 40 degrees, then the area of the ventilation space is calculated as a quotient of the total area of \u200b\u200bthe slopes and a factor of 300. And if the slope reaches 41 - 85 degrees, then it is calculated as a quotient of the soft roof area and a factor of 600. Let the total roof area be 50 square meters, the angle of inclination is 35 degrees, and the cross section of the ventilation element is 258 square centimeters.
The ventilation area in this case will be 0.167 square meters (50/300) or 1670 square centimeters. Then the required number of ventilation elements is five (1670/258). The number of ventilation elements that are installed on the ridge is half of their number on the roof slopes, that is, 3.
Installation of soft tiles
Manufacturers of flexible tiles do not recommend fixing it at temperatures below plus 5 degrees, because the shingles become brittle in the cold and the procedure for installing a roof made of soft tiles is difficult, and the lack of heat affects the tightness of the joints. In winter, joints and folds of shingles should be heated with a blow dryer or other device that generates heat flow. To lay the material on the roof in the summer, it must be taken in parts, because the protective film is poorly removed from the tiles heated by the sun.
When laying tiles, roofers often make the same mistake, as a result of which the roof has a different shade in different places. Remember that tiles in different packages may not be from the same batch, but from different ones, and therefore its color is different. Thus, it is necessary to use several packages of material at once so that the color of the roof is uniform.
To simplify work and ensure smooth lines, before covering the roof with soft tiles on the roof, a chalk marking of the slope is carried out along the crate and lining. Horizontal lines are drawn parallel to the eaves in increments of 80 centimeters. It turns out approximately 5 rows of tiles. Vertical lines are applied along the length of the slope in increments of 1 meter.
Installation of roofing from flexible tiles begins with the arrangement of the zero "cornice" row. Self-adhesive ridge tiles are glued end to end over a metal plank. From the edge of the slope you need to retreat 1-2 centimeters. On the other hand, the tiles are nailed, and the first row of ordinary flexible tiles is laid on top of the attachment point. If you did not buy ridge-cornice shingles, then you can attach simple shingles to the cornice, but without petals.
The first row of ordinary shingles begins to be laid from the center of the eaves, heading towards the ridge and gables. To move in hot weather on the roof, you need to use special manholes, otherwise footprints may remain on the roofing. First, the protective film is removed from the individual roof tiles from the back and glued to the base. Also, the tile requires additional fastening.
The tiles are fixed with nails, hammering them when laying two adjacent rows. When you drive a nail into the first row, you will also nail the second one at the same time. You can’t move the mount - hammer a nail from the very edge or into the center of the petals, since the soft tile roof device does not allow chaotic fastening, you can’t sink the nail too much - you need the hat to be on the same level with the roofing.
Approximately 4-5 nails are used per shingle. This is enough, since the bituminous tiles between themselves under the influence of solar heat will stick together and stick to the crate. The length of the nails is selected according to the type and thickness of the crate. The diameter of the nail should be approximately 3.2 millimeters, the diameter of the cap should be 10 millimeters.
When installing subsequent rows of tiles, remember that the lower petals of the material must correspond to the upper ones, which are located on the already nailed row. Along with this, it is customary to shift half the petal to the left or right.
Ridge tiles are obtained by dividing the cornice tiles into three parts according to the perforations. Mount the ridge shingles on the roof ridge, having previously cut the tile, while the short side should be parallel to the ridge. Nail with four nails so that the nails are located under the overlapping shingles with an overlap of 5 centimeters.
Proper connection design
In the process of installing a soft coating for the roof, quite often one has to face some difficulties and various objects to which the roof adjoins. Say, the most elementary object of this type is a stove heating pipe. In the area where the pipe adjoins the roof, a gap is always formed through which moisture flows.
To get rid of this shortcoming, you need to properly attach the flexible tile. To begin with, hammer the rail into the angle between the roof surface and the chimney. It is desirable that it has a triangular shape, like an ordinary wooden plinth. Further, it is recommended to bring the tiles onto this rail and directly onto the pipe. After that, a valley carpet should be laid on top of it, starting from the chimney.
It should cover the entire channel at a height of 30 centimeters from the roof surface. After that, the lower part of the pipe with a carpet and bituminous tiles is placed in a metal apron - lined with sheets of painted tin on all sides. To avoid the accumulation of snow behind the pipe, it is necessary to equip the groove by installing a pyramid with two faces close to the pipe. Thus, both snow and rainwater will fall on the slopes of the groove and flow down the roof, flowing around the pipe.
Sometimes you need to bring some communications through the roof. In such cases, it is best to use passage elements that are made specifically for tiles. They are attached to the base of the roof with nails. Such elements reliably protect the roof from leakage. For example, antenna passages of small diameter through the roof can be made with rubber seals.
Joint sealing procedure
To seal the roof of soft tiles, overlaps of the lining carpet and ordinary bituminous tiles on the valley carpet, passages of the ventilation system and various junctions, a special sealant is used. Immediately before applying the composition, clean the surface of loose materials, oil and dirt. On dusty and porous substrates, first apply a bituminous mortar. Remember that with an excess of glue, excessive dissolution of the bitumen may occur.
The composition is applied to one of the surfaces to be glued with a spatula. Maintain a layer thickness of 0.5 - 1 mm. The width of the sizing is indicated in the instructions. When pasting joints to pipes and walls, apply sealant over the entire contact surface. Grout the seams of the brickwork with mortar flush with the brick. The bonding process lasts 1-3 minutes, depending on the air temperature. At low temperatures, the composition must be heated before application.
Now you know how to cover the roof with soft tiles! In addition, you can always update the roof with flexible tiles without removing the old coating. Laying on top of old new shingles is not much different from laying from scratch. To do this, you need to lay an inverted shingle on the protruding cornice strip and glue it, and cut the protruding part along the cornice. Next, the tile is laid exactly on top of the previous pattern.
