How to cover the roof with a metal tile
The metal tile - one of the most popular and most used materials for the roof device. It provides the structure with high-quality protection in different weather conditions.
It has the following advantages: low cost, reliability, long service life, low weight and aesthetic appearance. It can be used for arranging coatings of any shape. In this article we will explain how to cover the roof with a metal tile.
Where to begin
At the initial stage it is worth paying attention to the careful measurement of all the slopes of the future roof.
note! Обязательно нужно промерять диагонали скатов, чтобы определить, нет ли на кровле скосов. Если же в значениях появляются отличия, то эта проблема решается посредством перемещения линии свеса, выравнивающей скос.
The profile should not “go” beyond the batten more than 40 mm, otherwise the coating material deforms under its own weight. Before work begins, the surface to be closed and the batten are checked for curvature.
For the installation of metal tile prepare such tools:
- scissors or hacksaw;
- measuring tape (meter);
- specialized self-tapping screws and drill screwdriver;
- marker.
Waterproofing and insulation
Before laying the tiles need to provide high-quality waterproofing. Waterproof insulation prevents condensation on the inner surface of the roofing sheet, and during the flow of water is retained by the absorbent.
note! Один из лучших материалов для водонепроницаемой изоляции – пароизоляционная пленка. Ее слой подвергается обработке абсорбирующими веществами и кладется сразу же над помещением.
The film is placed on the frame of the rafters under the wide counterbeam so that the overhang of the first layer from the edge of the eaves is no more than 20 mm, and the following layers are put with overlap of approximately 150 mm. The film is fixed with a mechanical stapler or galvanized screw nails.
Simultaneously with waterproof insulation, it is necessary to warm the roof frame. Thermal insulation plates are placed between the rafters (and depending on the quality of the material, ventilation openings can be arranged). Teplomats are attached with a construction stapler.
Crate
The crate is a support structure. Plates of metal tiles are put on it. For the installation of a support for the coating, wood boards with a width of 10 cm and a thickness of about 3 cm are used. Before installation, the boards must be subjected to antiseptic treatment!
On top of the vapor barrier film, to the rafters, from the ridge of the roof to its eaves, the bars are vertically attached. Crate nailed to them in a horizontal position. Boards are stacked either close to each other, or with minimal gaps (it depends on the type of tile).
Installation
Algorithm of actions when installing metal:
- A curtain rod is attached to the last board of the batten. An overlap of bars is allowed, approximately 10 cm.
- Next you need to start laying the cover plates, taking into account the type of roof. Tent (hip) roof must be covered, starting from the highest point, gently dropping down. The gable construction begins to be covered from the end of its slope. If laying is made from the left end, then the tile fits under the last wave of the previous one. If, however, from the right end, then it is necessary to install the sheets on top of the last wave of the previous row.
The sequence of laying tile sheets on the roof:
- The starting row of roofing material is attached to the crate with screws, near the ridge of the roof.
- Plates are placed overlapping (following under the previous one) so that the bottom edges become a flat line. It is advisable to fix them with self-tapping screws on the outside of the tile wave, under the bottom fold relative to the previous wave.
If you follow this method in everything, then you need to install several sheets that form a flat bottom border of the roof, aligned with the dimensions of the eaves. Next, the plate must be attached with screws to the crate. At 1 m? the roof area is enough to use for fastening from 7 to 9 screws.
note
All actions related to covering the roof with a metal tile should be carried out strictly according to technology, carefully selecting fully dried timber for the batten and rafters without holes from knots and other defects. There should be no signs of decay on it, which will ensure not only the durability and high-quality operation of the roof, but also an aesthetic appearance.
