Every person who has chosen this durable, practical material for roofing has questions about the installation of metal tiles. Metal roofing installation technology - video, instructions for the material used, which are useful to study before starting roofing work. We will try in this article to tell the main points on the installation and repair of metal roofing.
Installation Information
The metal tile is laid on a roof slope with roof pitch angle over 14 degrees. The length of the slope, taking into account the overhang of the coating from the roof eaves, determines the main size of the sheet.
As a rule, sheets are produced with a length of 6 m. In the event that the length of the slope exceeds the length of the sheets, additional sheets are cut and stacked with a transverse overlap of 35 cm.
Laying roofs made of metal starts from the right edge of the roof in the direction from the eaves to the ridge. For the installation of the roof, there is no need to mount a continuous crate.
It is enough to build a base with a step of boards equal to the wave of the coating.
However, when mounting the truss structure and the crate, more attention should be paid to this issue so that the roofing material does not sag as a result. You can learn how to properly build a crate from the video of a metal tile.
Under the metal tile for residential premises should be laid:
- waterproofing layer;
- heat-insulating materials;
- vapor barrier.
To fasten the sheets, screws with sealing rubber gaskets are used. Fastening is carried out in the deflection of the wave directly to the crate under the horizontal wave.
Advice. For the reliability of the roof, it is necessary to use 1 sq. m 6 fasteners.
Repair Information
The repair of a metal tile is caused by the appearance of such phenomena for a long time of use or errors in the installation:
- coating deflections;
- violation of the protective polymer layer;
- leaks.
In case of deformation of the roofing due to violations in the truss structure, a major overhaul of the roof is carried out:
- the old coating is dismantled;
- a new load-bearing roof structure is installed in compliance with all technological requirements;
- metal tile is installed.
There are cases when the polymer coating is deformed during installation. roofing material, there are chips, scratches.
After detecting such violations, the places of flaws should be treated with special paint. This will subsequently prevent corrosion.
It is possible to make partial replacement of damaged areas on the roof. To do this, sheets of the required length are taken and mounted in the same way as the main roofing.
Attention. To prepare sheets of metal tiles of the required size, it is not recommended to use a grinder with an abrasive cutting wheel.
Although many people think that the process of laying metal roofing is quite simple, it contains a lot of features, like laying other roofing.
Most of them can be found in search engines by searching metal tile + installation + instruction + video. Completeness of information and skills of work on the roof are the key to high-quality execution of roofing work.
