Installation of a roofing for metal tile

The metal-tile lining is an integral part of the truss system.

According to its design, it is a frame on which tiles of metal are fastened.

The device of a birch-bark for metal tile assumes the use of high-quality materials and strict observance of the sequence of operations.

Installation of the roofing for metal roofing is carried out by specialists. At the same time, some of the work can be done by yourself.

Roof construction for an individual house is an important stage of construction, and it must be done with proper quality.

The service life of the roofing structure as a whole is determined by the correct performance of all intermediate works.

Classification of the metal tile

The main material from which the roofing material is made is called a metal cascade, cascade type, steel sheet. On the outside and inside, the sheet is coated with a zinc coating.

On top of it there are several layers of different materials that provide the necessary reliability and aesthetic appeal of the material.

The photo shows the structure of the metal tile in the section.

According to technical specifications, metal roofing has a warranty service life of 15 years. When the installation of the lathing under the metal tile is made according to all norms and rules, the roofing material serves three times as long.

The cost of metal tile consists of several components.

The selling price in the building materials store is affected by the following characteristics:

• steel plate thickness;
• type of polymer coating;
• outer shape and color;
• geometric dimensions;
• is a brand of the manufacturer.

The sheet size is selected during the design phase. The distance between the slats from which the crate is mounted is determined by the length of the tiled wave.

Correctly calculated step of the lathing under the metal tile ensures its reliable fastening. When buying metal shingles, you need to familiarize yourself with the quality certificate for this product.

Like any building material, metal tile has its advantages and disadvantages. Among the first are strength, durability and attractive appearance.

Installation and fastening is easy - this means that the installation costs are low. An important point is that the installation can be performed at any time of the year.

The disadvantage of the material is the fact that the roof of this type requires additional noise insulation.

Even tiles of the brand cascade or monterrey have to be mounted on a well-prepared by hand crate. It is mandatory for such a roof and drainage of a special configuration.

Arrangement of the birch

The masonry under the metal tile is designed to evenly distribute the load to the rafters and walls of the house.

In practice, a crate of two types is used:

• solid;
• is a lattice.

When a solid construction is installed, the distance between the boards is kept within 10 mm. This is required in order to ensure air circulation.

The trellised crate requires fewer materials and it has a lower mass. The type of the crate is chosen depending on the size of the tile profile wave.

If you make a calculation for the metal cascade, then you can choose a lattice version of the design.

When you are going to mount the crate yourself, you need to perform an exact calculation of the dimensions of the structure. The wavelength of a sheet of metal cascade-type cascade is 300 mm.

Video:

From this it follows that the distance between the boards during the arrangement of the roof should be the same. The width of the sheet is 1150 mm, and the maximum length can reach 6 meters.

When designing, consider the overlap of one sheet on the other. Forming a cost estimate for the arrangement of the roof, you need to put a reserve of materials within 10% of the standard volume.

This rule applies to both metal and lumber.

How to determine the step of the

crate Many years of practice have shown that the lattice-type crate is the optimal solution for fixing the metal tile.

It is very important to correctly calculate the step size with which the cross bars will be installed.

These cross strips, in turn, are fastened with metal tiles.

It is necessary to know that depending on the standard, the length of the tile wave can be 300-350-400 mm. For a cascade-type product, the wave is 300 mm. Metal-type monterrey - 350 mm.

There must be a one-to-one correspondence between the wavelength and the pitch of the crate.

If the lath is installed with one step, and the metal tile has a different size, then this structure can not be mounted.

Selection of planks and beams

Thinking about how to make a crate for metal, you need to strictly control the quality of wood. When installing roofs from metal tiles, sawn softwood is used.

The complexity of the roofing system requires high quality from the materials. And this quality is determined at the design stage.

The board and the bar must comply with the parameters stated in the characteristics. This applies to the cross-section of the beam and the quality of the surface of the boards.

Before putting the material into operation, it must be dried and treated with a protective coating. At the same time, you need to make sure that the beam or board does not lose its original geometric parameters.

Construction of individual houses is usually carried out within a limited budget. It is very important not to allow cost overruns in the arrangement of the foundation, walls and roof.

You can optimize the costs of installing a roofing tile for metal tiles using specific approaches.

To do this, you must select a lightweight frame structure and make an accurate calculation of the need for sawn timber.

All the necessary measurements on the rafter system are carried out by hand using a metal tape measure. The latticed crate will require less boards and a bar than a solid one.

When measuring, you need to fix as accurately as possible the distance between the slats.

Many years of experience show that the size of the boards has a wide spread from the nominal value.

Since the crate must have high strength, it is recommended to collect it from a board thickness of 30 mm. This thickness is required for safety reasons.

In this case deviations from the average width can reach five or more centimeters. The boards need to be leveled before fastening. Calibration is easy to do by yourself.

It is not allowed to use sub-standard sawn timber for installation of a tiling for metal tiles.

Installing the

crate Before proceeding directly to work, it is advisable to draw up an action plan. Experienced professionals can do without this document.

The first step is to cover the roof slope with a vapor barrier. Laying and fixing the film is done using a bar with a section of 40x40 mm.

This bar is superimposed on the rafters and thereby presses the film to them. In the adopted terminology, it is called the control lattice.

The installation instruction prescribes that the first bars of the counter assembly are attached at the edges. This is done in order to stretch the film. And after that, all the others are attached by nails or self-tapping screws.

Correctly installed controllable grille is designed to create a ventilation space for the roof.

Free air circulation prevents moisture accumulation and mold formation. With special care, you need to fix the beams in the places where the valley is located.

In the contact areas of the beams and the waterproofing film, you need to monitor the integrity of this film. Otherwise, moisture will be continuously absorbed into the wood.

With the help of a grating, the film is stretched evenly. She should not sag and wrinkle.

So says the instruction on the use of waterproofing materials for the arrangement of the roof of metal.

If the project provides for the insulation of the roof, then the next action is laid insulation slabs.

Regardless of which type of insulation is selected, the thermal insulation sheet should be between two films.

From the bottom, the heater is protected from warm and humid air with a vapor barrier material, and on top with a waterproofing film. The photo shows the structure of the roofing cake in the section.

When the waterproofing film is laid, a lath is stuffed on top of it. And at this stage it is very important to perform the fastening of the battens in the manner prescribed by the preliminary calculation.

The installation and fixing of the starting board is carried out with special attention. It is nailed to the very end of the truss beam. The first board should be thicker than the ordinary board by 15-20 mm.

It is attached to the gutter. The following boards are fixed after a certain distance. This gap is determined by the type of metal.

If a metal cascade is selected for the roof, the distance between the boards of the battens should be 300 mm. On those sections of the roof, where there are valleys, the lath becomes solid.

Details and nuances

Since the drainage system is provided in any case, before installing the roofing under the metal tile, it is necessary to install brackets for attaching the gutters.

The scheme of the cast system is developed separately. And before laying the first board in the base of the battens, you need to make sure that all the elements of the gutters are fixed on the project sites.

Sometimes brackets are attached to the bottom board of the crate. There is no particular difference between these options, but it is necessary to know about them.

When you start building a house, you need to estimate the need for materials. After each stage of construction, the preliminary calculations are adjusted.

Roofing system is considered one of the main in the house. And to save on its arrangement is not accepted. The installation of the battens and the fixing of the metal tiles should be done carefully.

It should be remembered that the metal tile is not suitable for reuse.
