Preparing the roof for a soft roof - features of the technology. Step-by-step diagram for installing a roof made of bitumen tiles How to make a roof under soft tiles

Soft shingles are also known as bituminous shingles - modern roofing material, which quickly gained its popularity thanks to beautiful appearance, relatively low cost and ease of installation. The installation technology is quite simple and after studying the structure of a soft roof and the sequence of work, you can perform all the installation processes yourself.

Roofing from soft tiles carried out by laying bitumen shingles covered with stone chips on a prepared base. The technology of work, its features and safety instructions are included in the packaging. Before you begin installing soft tiles, you must calculate material requirements, purchase everything necessary for installation and check the availability of the required tools.

Step-by-step diagram of a flexible roof installation

1. Base structure

Roof installation made of soft tiles begins with the installation of the base. The base for the installation of a soft roof is made in the form of a continuous flooring.

Foundation requirements:

• it must be continuous;
• smooth;
• durable;
• hard;
• it must be nailable.

For the base device the following are used:

• plywood, made using phenol-formaldehyde glue (FSF), which has increased moisture resistance properties;
• oriented - particle board(OSB);
• edged or grooved boards of the same thickness and with relative humidity no more than 20%;
• other sheet moisture resistant material, suitable for the base device.

1.1. Board foundation technology

If you are installing a base made of boards, then for this Coniferous wood is used. The flooring is carried out on the rafters, if the boards high humidity, then their edges are fixed with self-tapping screws. The length of the board must be no less than two rafter span. It is desirable that the annual circles at the ends of the boards be close to the center, i.e. the core of the tree was approaching the rafters. Thus, the board works better in bending. The gap between the boards should be between 1 and 5 mm. It is important to take these features into account so that the base is of high quality, strong and durable.

1.2. Installation technology for large-panel base

Panel flooring is laid on a plank sheathing made with a certain step. The sheets are laid out at intervals and attached to the sheathing using self-tapping screws. When performing work in winter period The boards are laid with a gap of 3 mm from each other to allow the material to expand under the influence of temperature.

Large-panel flooring, unlike plank flooring, is much more profitable and reliable to install due to its qualities:

The thickness of the flooring depends on the material and pitch of the sheathing. It can be determined from the following table.

It is important to pay attention to chimney decking. If the width of the chimney exceeds 500 mm, then it is advisable to install a groove that will prevent the accumulation of precipitation.
After installing the base for the installation of soft tiles, the geometry and quality of the work are checked. The length, height, diagonals and evenness of the surface of the slopes are checked.

2. Drip device

Roof edge defends himself metal profiles - droppers, they are laid on the eaves overhang and fixed with nails with a pitch of 150 mm, in a checkerboard pattern. The drip joint is joined with an overlap of at least 30 mm.

3. Laying the underlay carpet

Underlay carpet, also known as MS OS barrier, laid in valleys ( internal corner stingrays) and on all eaves overhangs. Laying the barrier begins from the valley. A strip 1 meter wide is spread so that each slope extends 50 cm. A cornice is spread along the overhangs to the width of the cornice plus another 60 cm. The overlap of vertical seams is 15 cm, and horizontal - 10 cm. For fastening, the carpet is nailed with wide-headed nails along the perimeter in increments of 20–25 cm.

The remaining surface of the base is covered with a lining carpet. Provided the roof slope is from 120 to 180, 100% of the area is covered with an underlay carpet. If the angle of the slope exceeds 180, then the textiles are spread only on the ridge and the breaks of the slopes, 50 cm on each side. Strips of 50 cm are spread along the walls and along the pediment.

When installing a soft roof “trio”, “jazz” or “beaver tail”, covering the entire surface with an underlay carpet is mandatory. The material is laid in a horizontal direction from bottom to top. The overlap is coated with bitumen mastic. Each strip along the perimeter is nailed.

4. Installation of the gable strip

The gable strip is used to protect the ends of the roof base from precipitation and carpet material from wind exposure. The plank is installed on the edges of the roof and fixed with nails arranged in a checkerboard pattern with a pitch of 150 mm. At the joint there is an overlap of at least 30 mm.

5. Surface marking

Before installing a soft roof, you need mark the slopes. To do this, use a metric tape measure, a pencil and a painting cord. Surface marking is performed in the form of a grid and performs an auxiliary function. The horizontal line spacing corresponds to five rows flexible tiles, and the vertical pitch is 1 meter, this is the size of one shingle.

This grid helps to level the finishing flooring vertically and horizontally. Especially It is convenient to use markings if the slope is made with incorrect geometry or a structure like dormer window or chimney.

6. Construction of valleys

There are several ways to construct valleys. One of the most popular and simplest is laying the valley carpet. It is mounted on the lining material. Along the perimeter of the product is applied bitumen mastic, with a width from the edge of at least 100 mm. Additionally, the valley carpet is secured with nails at intervals of 200 - 250 mm. Nails are nailed along the perimeter, retreating about 3 cm from the edge. Excess material is cut off with a roofing knife.

7. Laying the starting strip

Installation of a soft roof begins with laying the starting strip. It uses a special ridge-eaves tiles, provided that it fits flexible roofing types of “sonata” or “chord”. If “jazz” tiles are installed, then the starting strip is used ordinary uncut shingles. When laying material with the cutting shape “chord”, “sonata”, “beavertail” and “trio”, you can use trimming ordinary shingles.

Lays the strip at a distance of 15 mm from the edge of the drip edge. Bituminous mastic is applied to the installation site, then the starting strip is mounted and additionally attached to the base using nails with a wide head.

8. Laying ordinary tiles

Before installation begins, several packs are unpacked and the tile elements mixed in random order. If this is not done, the roof will have pronounced spots of other shades. The “chord”, “beavertail” and “sonata” cut tiles have a protective anti-adhesive film that can be easily removed during installation. The “trio” and “jazz” material cuts do not have a protective film; they are equipped with special strips that protect the sheets in the bundle from sticking together.

The first sheet of ordinary tiles is placed on the starting strip with a vertical displacement of 10 mm from the edge of the strip. After which the shingles are fixed with nails. If the slope of the slope is less than 450, then 4 nails are hammered at a distance of 25 mm from the visible part of the shingle; if the slope exceeds 450, then 2 more nails are nailed along the axis (for “sonata” and “chord” cuts, additional nails are located in the upper corners). It turns out that each nail fixes two sheets at once. The nails must be driven in carefully so that they do not cut into the flexible material.

Next row stacked with different horizontal offsets depending on the type of cutting. When installing “jazz” tiles, the offset can be arbitrary, in the range from 15 to 85 cm. The final result is a drawing finished roof becomes chaotic. If you arrange the “chord” tiles in such a way that the rightmost petal overlaps the joint of the previous row, you will get a strictly orthogonal roof pattern. The offset material with trio, beavertail and sonata cuts is half the petal of the previous row.

A wide range of materials for roofing makes their choice quite complex and responsible.

IN modern construction The most popular roofing material is shingles, which in everyday life are called “soft” or “bitumen” shingles. This is due to its high quality, long service life, ease of installation technology, at an affordable price. Besides the fact that shingles are much cheaper metal roofs, it is also silent. It can be easily lifted onto the roof and installed without any problems. There are dozens of colors of soft tiles on the market.

Myself construction term“tile” does not entirely reflect the properties of this material: rather, it conveys ideas about the structure of the roof and about itself. basis bitumen shingles is fiberglass impregnated on both sides with bitumen with the addition of rubber. The front side of the shingles is sprinkled with stone chips. Fiberglass does not rot or corrode, and rubber bitumen has water-repellent properties. Stone chips protect the roof from the destructive effects of ultraviolet radiation, giving the material mechanical strength, has fireproof properties and retains snow mass.

The basis of the crumb is strong, durable and hard basalt granulate.

Basic rules for working with soft tiles

There are a number of rules that should be followed when working with shingles.

1. Before starting work, the material must be stored indoors. The tiles must be packaged and placed on pallets in rows (no more than 16 rows in height). Rolls of lining carpet used for priming should be stored in an upright position.
2. In order for the roof to be reliable and serve for a long time, the appropriate temperature conditions must be observed. This is possible provided that a continuous layer of vapor barrier is installed and there is insulation suitable for a given climatic region, as well as ventilation of the under-roof space.
3. You should not use bitumen shingles with different color codes and production dates for the installation of one roof slope. Otherwise, the color will be uneven, and the aesthetic impression of the roof will not be at the proper level. Depending on the architectural design, you can combine different shades.
4. It is better to carry out work when there is sufficient high temperature air (above plus 5 degrees). When installation is carried out at low temperatures (below plus 5), the packages are removed from the warm warehouse in small batches (no more than 5-6 packs at a time).
5. To protect the roof from possible damage, the material is cut on a separately placed board.
6. Laying of soft tiles is carried out on roofs with a slope angle of 15-85 degrees, while the calculated packaging surface is given for roofs with a 45-degree slope. As the angle decreases, material consumption also decreases. The use of hexagon-shaped shingles is possible on roofs with a slope angle of at least 20 degrees.
7. Soft tiles are not weldable; it is not permissible to use a torch to process them. The adhesive surface should set under the influence of sunlight. If construction is carried out in regions with strong winds or work is carried out in low temperatures, you must use a special bitumen adhesive (for example, “Plastal” or “Shingle Stick”).
8. Adhesive layer with protective film must be protected from premature destruction. Therefore, soft tiles should not be exposed to ultraviolet rays.
9. The transparent film covering the bottom (adhesive) layer of the sheets is removed immediately before installation.
10. To avoid marks from shoes and stains, you should not walk on the roof in sunny weather. Roofing cats or ladders are used for moving.
11. The tiles are not laid directly on the insulation or concrete screed.

Features of lathing installation

When creating sheathing for bitumen shingles, it is necessary to take into account some nuances.

• The sheathing should not be arranged in accordance with a certain step, have steps or unevenness. The fitting of joints should be done very carefully.
• The perfectly flat surface of the sheathing ensures a tight fit of the roofing material and helps prevent possible leaks.
• For a high-quality roofing installation, it is necessary to carefully select both the tiles and the material for the sheathing.
• Please note that a half-edged board is not suitable for soft tiles. As already mentioned, flexible tiles are laid on roofs with a slope angle of 12 to 85 degrees. With a flat roof, it is better to first lay a lining over the entire surface.

If there is a steep slope, it is necessary to install underlayment around the perimeter of the attic windows, around pipes and antennas.

• Should be prepared in advance wooden sheathing. As a rule, it is made from edged boards a flat surface with a very tight installation pitch. Fibreboard, OSB, and moisture-resistant multilayer plywood are also suitable materials. The listed building materials, in addition to performing their main function, retain moisture.

Some manufacturers suggest using dry tongue and groove boards (their humidity should be within 20%). However, this material does not justify itself, since the board can twist, and individual boards may differ in thickness by 2-4 mm, which is unacceptable in the case of flexible tiles, since this roofing material exactly repeats all the errors of the base.

The fastening of the sheathing should ensure its absolute immobility. The main requirements for the sheathing itself are:

• smoothness;
• strength;
• dryness;
• presence of ventilation ducts.

In accordance with the requirements of SNiP, the moisture content of the material should not be more than 20% of the dry weight.

When installing the sheathing, you should take into account the number of future loads on its surface: it must withstand all possible loads and not be subject to deformation.

Taking into account the thickness of the snow cover in the Russian middle lane optimal thickness material for the sheathing (plywood or boards) and the pitch size of the rafter system is calculated based on the pitch of the rafters.

For example:

The rafter pitch is 500 mm, which means that the thickness of the edged board should be 20 mm, and the OSB should be 10 mm.

At rafter step at 1200 mm, the thickness of the board used should be 30 mm, and OSB - 20 mm.

Since the basis for flexible tiles are inorganic substances, they are protected from mold and mildew, which cannot be said about wooden structural elements. All wooden parts should be thoroughly impregnated with an antiseptic composition.

If the tiles are covered on one side with a self-adhesive layer and a protective film, their installation is much faster and easier, following a certain step. Immediately before laying, the film is removed and the tiles are secured to the sheathing using nails. During the heating process sun rays the lower part of the tile is attached to the surface of the sheathing and adjacent tiles, which ensures the reliability and tightness of the roof covering being installed.

To obtain a continuous coating, a wood-based lathing under flexible bitumen shingles is installed in two layers, resulting in rafter structure a smooth continuous surface is arranged wood flooring with a completely smooth surface.

The joints of the base parts are spaced apart, the gap should be 2-4 mm, and the difference in height should be no more than 2 mm. To fasten boards (plywood), use rough galvanized nails or anodized screws: their length should be 2.5 times greater than the thickness of the base. It is necessary to avoid distortions and strictly observe the dimensions of the slopes (they must correspond to the project).

Before installation begins, it is necessary to carry out a control measurement of the slopes to establish their perpendicularity and flatness in relation to the cornices and ridges. Measurement data is necessary to ensure the geometric correctness of laying soft tiles.

To prevent friction of flexible tiles or the appearance of kinks, the sheathing should be arranged in such a way that there are no sharp corners or kinks.

For this purpose, during preparation and fitting work building materials for lathing installation soft roof should be as close as possible to rounded shapes in everything: absolutely all frame lines should be without corners, smoothed out as much as possible.

A similar design can be obtained using an edged board whose width is approximately 140 mm.

It should be stored properly to avoid cracking, trays and humps (i.e. grooves and bulges) on the surface.

Ventilation device

A ventilation system is necessary to ensure free air circulation, which is necessary to prevent the formation and accumulation of condensation in the lower part of the base. Lack of ventilation can lead to rotting of the rafter system and the formation of ice and icicles during the cold season.

Main elements roofing system ventilation are:

• ventilation outlets;
• vents (installed in eaves overhangs);
• the air gap between the waterproofing and the base is at least 5mm.

Marking

For high-quality styling soft tiles, the roof should be pre-marked, since due to the small size of the shingles, the rows are often bent.

This drawback is especially noticeable on roofs with a large area.

The order of marking is as follows:

• On the slopes in the transverse direction (from bottom to top or vice versa), two parallel straight lines are drawn at a distance of 500 mm from each other. These strips will provide a horizontal shift of the soft tiles relative to each other.
• Lines can be drawn in any part of the slope - optimal place is the edge where the laying process begins.
• Shingles are installed in rows, so many perpendicular lines should be added to the parallels, relative to which the shingles are laid.

The step between perpendiculars should be 250 mm.

The nuances of installing soft tiles

• The installation process begins from the bottom of the roof slope.

The first row is laid upside down. You can also use a special self-adhesive strip. The first row is laid in orientation relative to the roof slope.

• When laying the second row, you should already be guided by the markings. Since the lower parts of the shingles are equipped with a self-adhesive backing, they can simply be pressed onto the base. There is no self-adhesive layer at the top. Its fastening is carried out using special nails with wide heads. They are hammered in the middle and along the edges of each element. Four nails are used for one dead strip of soft tiles.
• Each next row is laid with an offset of 0.5 m (the material itself and its parameters require such a shift).
• The petals of the row being mounted should be located between the petals of the elements of the previous row.

When attaching all elements, regardless of position and row, the same rules should be followed.

Subtleties of laying tiles on the ridge and valleys

Features of the installation of flexible tiles mainly consist in their installation on the ridge and valleys.

A minimum number of them is required on a roofing ridge: the design of the ridge can be carried out by purchase metal element or made from shingles. These elements can be cut from soft tiles.

Ridge installation– the process is simple: you need to bend a fragment of shingle over the ridge and fix it with galvanized nails or self-tapping screws.

Particular care should be taken when installing valleys, since it is at these points that leaks most often occur.

The valleys must first be glued with a backing.

This measure is necessary even if the roof has a significant slope and there is no underlayment. The ridge and joints between plywood or OSB boards should be glued in the same way.

In valleys, soft tiles should be cut in the direction of this element, and not bent. To increase the strength of the joint, glue it with an additional layer of shingles.

Fragments are cut out from strips of soft tiles, which are glued onto adjacent slopes with an overlap over the already installed layer of bituminous shingles.

CONCLUSIONS:

• Soft tiles are the most popular roofing material.
• Its main advantages are lightness, ease of installation, high quality, durability and availability.
• When working with shingles, you must adhere to some rules: store the material indoors, install it at an air temperature above +5 degrees.
• The sheathing must be continuous, smooth, and completely level.
• To prevent the formation of condensation in the under-roof space and subsequent rotting wooden elements it is necessary to arrange a ventilation system.
• For high-quality installation, preliminary marking of the slopes is required.
• Installation of soft tiles begins from the bottom of the slope.
• Installing a ridge is not particularly difficult, but when installing valleys, special care must be taken to prevent possible leaks.

From the training film you will learn about the features of installing SHINGLAS flexible tiles.

Covering the roof with a soft roof has become widely popular in modern house construction. Good physical characteristics guarantee protection inner surface buildings from exposure external environment(weather precipitation, climatic conditions). Interesting design, little weight, ease of operation allow you to lay the coating yourself on any building. Individual installation of a soft roof requires accuracy and patience. Additional benefits will bring knowledge of the main nuances of the roofing process.

Common types

Materials for soft roofing are considered analogues of roofing felt. Thanks to their flexibility and strength, they can cover any surface on the roof without causing any problems. Regular modification allows you to improve quality characteristics tiles, which increases their service life. It is customary to distinguish three types of roofing materials:

1. Rolled. They are laid in strips and secured using fusing or overlapping methods. Used for roofs with a slope angle of 3-9 degrees. Suitable for the construction of industrial facilities.
2. Mastics. Delivered chilled or heated. Installation occurs by spraying the substance over the entire roof area. The result is a solid roof without characteristic seams and cracks. Such soft building materials are suitable for covering flat roofs.
3. Bituminous. Presented in the form of sheets of tiles, cut into several parts. They can be decorated in a variety of ways: have straight or curly edges, have a plain or textured color type. Interior sheets contains duct tape, which allows you to firmly attach the material to the prepared base. For additional fixation, bitumen shingles are fastened with 4-6 nails. Suitable for roofs that are not constantly exposed to the sun. At significant temperatures, the material can melt and stick together into a total mass.

This classification of soft roofing materials helps determine the necessary products that suit individual needs.

Stages of creating a roof

Using soft tiles, you can cover a roof of any slope exceeding 11.3 degrees. An assortment of manufacturing companies, varying degrees of quality, and a certain classification make it possible for the consumer to choose optimal material for the implementation of soft roofing.

In addition to the reliability of the means used, special attention is paid to correct execution basic procedures. Standard technology The installation of a soft tile roof requires compliance with several stages.

Coating base

On preparatory stage the roof base is completed and the rafters are installed, as in the usual covering procedure. The reliability of the roof depends on a two-layer sheathing, consisting of rigid boards and OSB boards, plywood, resistant to moisture. It is important to remember that this part of the roof must:

• have no gaps, irregularities, cracks, with the exception of seams, the distance between which is about 2-5 mm;
• contain thick boards, which will provide a greater degree of reliability;
• It is advisable to have treated wood coniferous, the normalized humidity of which does not exceed 20%.

When using OSB, sheets of material are laid in a checkerboard pattern, in the case of boards - parallel to each other. Subsequent actions are determined depending on the intended purpose of the roof and the time of year.

Roofing process

At the second stage, the covering scheme for a non-insulated building involves placing a carpet of soft tiles on top of the sheathing. Otherwise, the structure of the roof changes significantly. On the internal cladding (made of plywood, chipboard, plasterboard) and the sheathing for this part of the roof, 2 layers of additional means are installed to insulate the vapor barriers separated from each other. Rafters with sheathing are placed on top of the structure, and finally covered with underlayment and tiles.

Lining

The underlayment carpet is spread completely over the entire surface of the roof. If the slope of the slopes exceeds 18 degrees, the material is laid around the perimeter around the projections and chimneys. It is recommended to purchase tiles and coverings from the same manufacturer, which will allow the products to interact and complement each other as much as possible.

Laying tiles

Basic information on the use and method of application of the tiles is provided by the manufacturer. If possible, installation is carried out by installing metal valleys, after which they proceed to the coating. In general, installation begins from the middle of the bottom rows. The material is fixed by driving 4 nails into the fastening.

In the area of ​​slopes, straight tiles are applied first. Then they move on to volumetric tiles, the installation of which is carried out in the direction from bottom to top. The work done is consolidated by heat treatment.

Special attention is paid to the coating of ridge surfaces. The presence of ventilation outlets involves the use of plastic aerators that will protect the air ducts from blocking. After fixing the element from above, it is covered with soft tiles, which will support overall design Houses. The coating is installed in the direction of frequent air flows, moving from bottom to top. Each unit of soft roofing should overlap the previous one by several centimeters.

Peculiarities

According to the weather criterion, the procedure for covering the roof can be carried out:

1. In rainy weather, then work begins after ensuring waterproofing. Then they begin construction of the control sheathing, plywood covering, underlayment and shingles.
2. In dry weather, they begin by providing a vapor barrier. Afterwards, the sheathing is formed, noise-insulating materials are laid and covered with top cladding. Installation of waterproofing insulation and control sheathing completes the installation of the roof under a soft roof.
3. In cold weather, the process is carried out similarly to the previous stages of work: plywood and underlay carpet are installed under the soft tiles.

Additional equipment

The technology of a soft roof device can be developed taking into account the creation ventilation system on the roof. This practice will increase the life of the roof by several years. Due to the fact that the material used does not allow water and steam to pass through in any direction, the question arises as to the advisability of creating a system that maintains air circulation to prevent the appearance of mold and mildew.

The ventilation system design may include:

1. Vents located in the eaves area. Thanks to their properties, the channels will ensure air circulation on the slopes of the roof made of soft tiles.
2. Gaps between the roof and insulation materials, which will allow you to regularly fill the latter required quantity air.
3. Analogues of pipes, mainly located along the surface of the ridge.

The normal functioning of the system is explained by the presence of three components: channels for air intake, gaps between coating elements and individual hoods.

Advantages and disadvantages of the material

Soft tiles have a wide range of advantages that explain the distribution of the material on construction sites. Physical properties material indicate high level sound insulation, water resistance. Resistance to corrosion, weather conditions, and water allows the use of soft roofing to cover roofs for a long time.

To the main positive features include a pleasant appearance. The wide variety allows the use of tiles for roofing buildings of any design. Compact dimensions and low weight facilitate the processes of transportation and operation of products. As a result, the buyer has the opportunity to independently carry out necessary work for installation of tiles.

Although there are significant benefits, these materials can be quite expensive for certain populations. Features of roofing technology include manual installation of sheathing, which entails increased wood costs.

The technology of installing a soft roof requires compliance with certain building regulations. The efficiency and effectiveness of work depends on many factors that relate to storage conditions. An important role when installing a roof is played by the expediency of choosing a certain type of flexible tile.

After deciding on the need for roofing, the consumer must ensure that:

1. Purchased materials and tools were stored indoors. The underlay carpet is installed vertically, the sheets or logs used are installed horizontally, no more than 16 rows in height.
2. Thermal insulation was required when installing the roof. Can act as insulation mineral wool for construction. Liquid is removed from the material due to circulation air mass in ventilation ducts.
3. The purchased tiles matched in appearance, shape, and color. Belonging to the same batch will ensure that the material is identical in physical characteristics, which will emphasize the holistic appearance of the roof.
4. It is recommended to avoid roofing at temperatures below +5. Cold increases the brittleness of the material, which exposes the tiles to additional damage. Careless handling will lead to damage to the products used and their unreliable installation on the roof.
5. During the installation process, it is recommended to use only weld-on tools. The use of a burner is not advisable. Additional fixation is guaranteed by the use of adhesive solutions.
6. In sunny weather, it is advisable not to walk on the roof without special devices. Exposure to direct rays heats up the tiles, which can cause the worker to deform the material.
7. The base for a roof made of fused materials must be solid and continuous. This will increase their durability and service life.

Installing a soft tile roof is considered a fairly easy process. Carrying out the work independently does not require specialized knowledge. To get an effective result, it is enough to have an understanding of the rules and features of the coating.

The good thing about flexible tiles is that they can be laid by one person, even without an assistant. This is possible due to the light weight of the parts called shingles and small sizes. The largest dimension of a shingle is a length equal to one meter. Installing a roof made of soft tiles, the installation technology of which we will consider in this article, is a fairly simple matter if you strictly follow the instructions and recommendations of the manufacturer of the purchased bitumen shingles. The main thing when building a roof is to prepare the most even surface on which the soft tiles will be laid.

Rafters for soft roofing are made in the same way as for any other roofing material. But you need a two-layer sheathing. The first layer - to give rigidity - is made from edged boards. The second - to create a flat surface - is made from moisture resistant plywood or OSB boards. The construction of a roof made of soft tiles can be done in different ways. If the roof is built over a building where its insulation is not provided, then the nodes of the roofing “pie” will look like this:

1. A layer of soft tiles.
2. Underlay carpet.
3. Moisture-resistant OSB board or plywood.
4. Lathing from edged boards.
5. Rafters.

The “pie” of an insulated roof, under which an attic or simply warm attic, will be like this:

1. Soft tiles.
2. Underlay carpet.
3. OSB or plywood is waterproof.
4. Edged board.
5. Countergrid
6. Waterproofing.
7. Rafters.
8. Insulation.
9. Vapor barrier.
10. Sound insulation or additional layer of insulation.
11. Lathing for internal cladding.
12. Internal lining.

Internal cladding is usually done with sheets of plasterboard followed by wallpapering. But, according to the taste of the developer, it can be done with clapboard, plywood, chipboards or OSB... The order of work may be different. If the climate or weather permits, then, of course, it is more convenient to start with a vapor barrier. Secure it with internal sheathing, lay a layer of sound insulation and sew it all up internal lining. After this, calmly lay the insulation between the rafters, tighten the waterproofing and secure it with a counter-lattice. Then everything is done in the same way as in the case cold roof. A sheathing of edged boards is installed, OSB or plywood is laid, and underlay carpet and bitumen shingles are glued. If the summer is rainy, then it is wiser to first lay the roof in this order:

1. Waterproofing.
2. Countergrid.
3. Plywood or OSB are waterproof.
4. Lining material.
5. Flexible tiles.

After this, under the protection of the finished roof, you can do any work in the attic or attic. The technology of lathing for soft roofing is discussed in more detail in the article:.

Tools

To work with bitumen shingles you need a fairly simple set of tools:

1. Hammer.
2. Cord.
3. Putty knife.
4. Metal scissors.
5. Roulette.
6. Gun for applying sealant.
7. Roofing nails.

Laying technology, work procedure

By purchasing bitumen shingles, components and Consumables, it is best to select them so that they are all from the same manufacturer. This will make it easier to follow the manufacturer’s recommendations and installing a roof made of flexible tiles will not be as difficult as it seems at first glance. And the components of the roofing carpet will “work” better together.

Underlay carpet

It is recommended to lay the underlay carpet over the entire surface of the roof. But if the slope of the slope is more than 18°, then there is an opportunity to save a little. With such slopes, lining material can only be laid along the perimeter of the roof - along the eaves, along the ridge, along the ends of the slope, along the outer curves of the roof, around chimneys and ventilation outlets and in valleys.

Metal strips

A fully completed insulated roof eaves assembly will look something like this:
The drip strip is mounted directly on the rafter beams under the waterproofing layer. His task: to protect wooden structures(rafters and wind board) from condensation formed in the ventilation duct and flowing down waterproofing material down . After laying the lining material, fasteners for the gutters into which the gutters are installed are nailed to the cornice. Then a cornice strip is nailed along the entire length of the cornice so that its lower edge is inside the gutter. Thus, water flowing from the roof is removed into the drainage system without getting on the wooden sheathing structures and on plywood or OSB boards. If the roof is intended to be “cold”, which means there will be no waterproofing, then a drip strip is not needed. Drainage system also an optional element. Then you can only get by cornice strip, which in such cases is also sometimes called a dropper.
At the ends of the roof, on the gables, starting from the eaves, apply an end or wind bar with an overlap of at least 20 mm. As an option, in valleys you can lay not a valley carpet made of the same material as bitumen shingles, but metal valley. In reality it will look something like this:

Installation of flexible tiles

If the roof structure has valleys, then first you need to lay a valley carpet or install a metal valley. After this, you can begin laying the main sheet of soft roofing. Installation of bitumen shingles begins with laying the cornice row. For this, eaves-ridge tiles are used. If it was not on sale at the time of purchase, you can use an ordinary one by cutting off the petals. When laying soft tiles, you should follow the recommendations or instructions from the manufacturer. In the valley, bitumen shingles can be laid in different ways:

Let's look at how you can make a ventilated ridge for a soft roof. His turn comes after the completion of laying the main sheet of bitumen shingles. To allow air from the attic or from ventilation ducts the insulated roof had the opportunity to escape into the atmosphere, when installing the base, it is necessary to leave in the ridge unit the distance between the opposite roof slopes within 200–300 mm.
And to prevent moisture from rain or snow from getting under the roof, this gap is closed with its own “roof”. To do this, you can use ready-made ridge elements, for example, the following:
Fastened with self-tapping screws or nails according to the manufacturer’s recommendation:
Or you can make a ventilated ridge yourself, as shown in this video: Here you can see that along the upper edge of the slopes, perpendicular to them, bars with a cross section of about 50x50 mm are nailed. The pitch of the bars is determined by the thickness of the plywood or OSB board so as to prevent the “roof” of the ridge from sagging. The width of such a “roof” can be determined independently, within reasonable limits. A protective ventilation mesh is attached to the ends of the bars so that debris, insects and small birds cannot get under ridge knot. Finally, elements of ridge-eaves and row tiles are attached to sheets of plywood or OSB boards. The result is shown in the photo below.
As an option, instead of a completely “breathing” ridge, you can make the roof continuous with the installation of ventilation hoods:
Subsequently, if the “power” of the ventilated ridge is not enough to ventilate the roof, you can place special aerators on its surface, the attachment points of which are shown in the following video: At this point, the roofing installation can be considered complete.
