The device under the metal furring: step, materials and technology

The roof is covered with metal

Width - 1250 mm, length -. Not more than 8 m thickness product is from 0.45 to 0.55 (sometimes up to 0.6) mm. it standard sizes of sheet metal roof. Price depends on the area of ​​the surfaces, the thickness of the material manufacturer, the quality of protection varies from 3.5 to 5.5 cu per m².

Depending on the material from which the article is made, there is metal: Steel with zinc or aluminum-zinc coating, aluminum and copper. The latter two options are too expensive to be widely used in construction, so only necessary to dwell on the steel sheets.

EXAMPLE arrangement roofing "pie" using metal

Depending on the geometric features of the profile, metal is divided into several types with beautiful names:

• Monterrey - the most famous views. Externally, such a sheet profile resembles real tiles with rounded edges;
• Cascade - the strict classic look. Profile resembles a bar of chocolate. Straight lines facilitate coating complex roofs;
• Joker - a wave of such coatings resemble the correct tiles. In the sectional view, they are ideal hemisphere;
• Banga - a modern form of the profile, which is due to its height creates a three-dimensional effect;
• Andalusia - profile features allow to mount such a sheet metal roofing on a roof with special locks, which also conceal screws;
• Shanghai - Chinese view of the profile that has full symmetry.

Variety of shapes and sizes of sheet metal

This is only the most famous, having a wave height of various sizes, metal sheets for roofs. Their price depends on the shape of the profile. Relief features of roofing sheets are forced to comply with certain roofing technology of metal.

roofing technology of metal

The simplest case - a gable roof installation. Nothing complicated in this work there. Initially, under the metal lath preparing step which depends on the profile type, sheet thickness and the angle of slope. It is constructed from planks of thickness up to 25 mm, and may be covered with plywood in some cases.

The circuit arrangement of batten metal profiles

Then choose which side to start laying the sheets. The big difference in this, but it is more convenient to do it with one hand, where there is a sheet of capillary grooves. In addition, each next sheet will go on top of the previous one. Otherwise, it will have to slip. The first sheet to be installed completely flat relative to the purlin and parallel to the plane of the ledge with an allowance of 2 - 3 cm. On how it will be put, it depends on the result of the work. After deviation of only 1 degree in the beginning will in the end to considerable care from the right direction.

EXAMPLE arrangement wooden lathing

Fastening sheets is done using special roofing screws having a rubber gasket. They screwed screwdriver into the cavity between the waves without effort, as the liner may be damaged. Then mounted wind and ridge elements. These are the basic steps roofing technology of metal. Some of the important nuances of this process it is necessary to understand in more detail.

Useful advice!When installing metal with their hands can not use the grinder, and only a pair of scissors or a hacksaw. When the grinder protective polymer layer is destroyed by heat, which leads to premature corrosion.

Process metal mounting

The device under the metal furring: step, materials and technology

In construction, there are 3 types of crates for the roof: solid, sparse, and of sheet materials. Solid involves mounting boards butt to each other, which requires a large amount of material.

The design of sheet materials such as plywood and OSB sheet, Versatile and well suited for the flooring of metal on it. However, the most suitable for it is sparse crate under the metal, a step which must be calculated individually for each type of profile.

For the calculation of this step is necessary first to arrive edged boards parallel to the eaves and the ridge parallel to the latter at the top of the ramp. Then, the sheet is placed so that its lower end a spade rested first batten board. The upper part of the sheet should lie on the nearest to the ridge board.

Then, place is marked for all intermediate batten boards. They should be nailed with a pitch such that the sheet is laid down for each of them the top of the stairs. bends space should not be between the boards. Strictly speaking, under the metal lathing step must be step a transverse wave.

Vertical and horizontal spacing battens

Waterproofing roof of the house under the metal

Once the crate is ready, it's time the house roof waterproofing under the metal. This stage is excluded from the entire process can not be. It protects the rafter from moisture which may get under the cover, and does not collect the condensate on the interior surfaces of the sheets.

A large number of modern, efficient and durable materials, such as membrane and anti-condensate film. Use materials on bitumen basis, such as the roofing material is not recommended. The film has all necessary to ensure moisture protection properties and meets all building codes. Its easy to lay. It does not require any additional tools and procedures. It has the properties of fire, as used on hardwood floors can not be said of the roofing material.

Proper mounting sheet metal with self-tapping screws

Stack film must be parallel to the eaves, starting from the bottom. Each subsequent roll is rolled to a previous lapped. Secure the material can be a conventional staple gun to the wood batten. Properly mounted the roof of the house under the waterproofing metal roofing will provide quality protection of wooden structures from moisture and wind.

Useful advice!If the polymer film, it is necessary to cover the paint was damaged while laying the sheets. It can be purchased at the same store, where all the material.

installation of metal with their hands Features

If you want to save on construction or replacement of the roof of his house, it is possible to carry out installation of metal with their hands. It's not as difficult as it seems at first glance. The most important is the first sheet to be laid as flat as possible. Its lower edge should be parallel to the eaves. This list is attached in the middle of a single self-tapping, to be able to rotate.

Then stack further 2 - 3 leaf, observing their relief features. They do not attach to the crate, and only fastened together. Then the entire structure of the multiple sheets aligned parallel to the eaves, and finally fixed with screws. Subsequent sheets already stacked without any problems. Align only their bottom edges relative to each other.
