Asbestos slate

There are three types of slate coating: metallic, Euro-standard and asbestos. Metal is made of thin galvanized steel, covered with a protective polymer layer. The Euro-slate structure includes cellulose and basalt fiber, fiberglass, and also jute. The latter species is the most popular. The material has a very high stiffness, because asbestos fibers even exceed steel in their strength. Connects them to cement. Asbestos threads are evenly distributed on the sheet, which creates a good reinforcing mesh. This helps to increase the toughness and strength of the coating.

There are different types of wavy asbestos slate:

  • WU is a wavy slate with a reinforced profile. This material is used for roofing in the construction of industrial buildings.

  • BO is a slate with a regular profile, having a rectangular shape. Not only the sheets themselves, but also other elements of the roof, for example, a ridge for the roof, can be made of it.

  • HC is a wavy unified slate. It has a good wave width and sheet size. All this can significantly reduce the number of joints.

Preparation for mounting slate

How roofing works are performed using slate

To attach slate sheets start from bottom to top vertically. The meaning of this is that the upper wave overlaps the lower one. In this case, one sheet should be laid on the other not less than 10 cm. In order for all sheets to be at the same distance, a tape or a rope is pulled along the edge.

There are two ways to stack sheets. The choice depends on the roof slopes. If the vertical slope is narrow and the horizontal slope is wide, then an offset laying is used. This option is remarkable in that it does not involve cutting the sheets at the joints. The sheet is attached to the crate on one wave to the side. Each next sheet is fixed on the previous one, overlapped by one wave. At the same time laying is made in horizontal rows.

Proper installation of slate on the roof

In the case when the vertical slope is narrow and the horizontal wide, the installation with a cut angle is used . At the same time, angles are removed from the diagonal sheets, and the joint is made with a small gap. This method allows to avoid the appearance of cracks and defects in roofing.

To install the sheets use galvanized screws with rubber gaskets on the caps. The best effect is given by the fittings, in which the thread does not reach the cap, because it does not damage the roofing material itself. Screws tighten tightly. Usually, every third wave is fixed, or it is retreated on each side by one wave and only the second and last but one slope is fixed.

Before cutting the sheet, it must be moistened with water. Then the slate for the roof does not crumble, does not dust and is easy to cut. For cutting using a hacksaw or angle grinder with a small diameter disc. But there is another way: sometimes several holes are made on the cutting line at a distance of 2 cm from each other, and then the necessary part is broken off.

Before cutting a sheet, it should be moistened with water.

After the installation of the sheets is finished, it is usually transferred to sealing joints using foam or bitumen tape and to install the ridge, which should cover the sheets themselves at least 20 centimeters. All roofing works are completed by fixing drainpipes and gutters.

Painting slate

The use of water dispersion paint has a very important advantage: the mixture seals all microcracks on the surface of the material. In winter, roofing slate, covered with such a composition, becomes more slippery, which contributes to the removal of snow and moisture.

Alkyd paints make the surface more elastic, and this prevents the appearance of defects. Also, this type of coating protects the roof from fading.
