Tiles are considered a representative of the oldest roofing materials. Once, during the days BC, there was already a tile, and it was covered at home. The material is so successful that even today its popularity does not fall.
Natural tiles are not all the same, it can be species: traditional ceramic tiles made of clay; and cement-sand tiles made of concrete. But there are excellent roofing materials that are an imitation of tiles. For example, made of metal – make metal tiles, from bitumen – make soft tiles. It should also be noted polymer -sand, metal -plastic, glass and other types of tiles.
Natural tiles are characterized by an insignificant indicator of linear temperature expansion, fragments have a pair of vertical locks. – That’s why there are almost never cracks on the tile. The tiles can be used if there is a stone, brick, wooden structure; during construction or reconstruction.
There is an opinion that, a certain restriction in the use of tiles is its impressive weight, massive rafters are required, a large consumption of lumber for a crate. But in fact, this is not so, the roof of cement-sand tiles is only 30% more pressure on the surface than the metal coating.
