Laying roofing. Main nuances.

Modern industry offers a wealth of materials for roofing. From the viewpoint of stacking two types of laying: soft and rigid roofing material such as slate.

Any styling begins with batten mounting truss system. Lathing is different for different types of coverage. For soft roof it will be continuous, and for rigid roofing type roof tiles, slates or sheet metal lath such stuffed distance. The distance between the crate depends on the type of material chosen.

Laying soft roof

shingles used for frame construction. It is made of glass fiber and bitumen. Outside shingles coated basalt granulator. The strength and durability of the material to provide mechanical impact resistant fiberglass. The coating does not rot, it does not start mold and lichen. It provides waterproofing bituminous base. In order to protect against damage bitumen sprinkle granulator or shale rock dust, which plays a protective role against fire, and also gives a decorative roughened surface. Moreover, the roughened layer blocks snow slide off the roof.

At the bottom of tile adhesive has a base that is protected by a film. It is glued to the prepared solid base. For fasteners used staple gun.

Before you buy roofing material, it is necessary to pay attention to the properties of the tile, not to buy a defective roof. Qualitative tile light, it effortlessly and bends without cracks, has no strong smells, with it not exfoliate granular layer. It is best to buy a tile, produced less than a year ago.

Laying slate

Laying rigid roof can be considered an example of slate paving. Before laying it cook crate. The distance between the bars made from 50 to 80 cm, depending on the brand cipher. Slate is fastened to the sheathing with nails. Sam fasteners performed carefully, in compliance with a special technology. Initially, the hole is drilled in the upper wave is 2 mm longer than the fastener material on the nail superimposed rubber gasket, then carefully, not until the end of the nail is hammered, not to damage sheet.

Laying begins from the bottom on the windward side of the roof. Laying of the first sheet - it is responsible, because it affects how smooth will the entire roof. Therefore, for the first row is used plumb lines and roulette. The size of the overlap depends on the angle of the roof. For example, if 45 degree roof enough overlap of 10 cm.

- Laying vrazbezhku. This method involves the stacking of each sheet shifted by several waves - one to four with respect to adjacent sheets. Docking takes place on the steps. This method is commonly used for the roof slope, sufficiently wide horizontally but in a small slope.
- No offset. According to this technology slate sheets stacked evenly, equally without bias. All joints stand in line. The material does not allow double overlap, i.e. superimpose more than one sheet of slate. Therefore, the edges being cut to an angle of 30 to 60 degrees. This technology is used for the roof of a wide slope, but having small size in diameter.
