Slate and today continues to be one of their most popular roofing materials. For many years, both the type and the composition of the slate have remained unchanged: wavy sheets made of asbestos cement. But recently, a new material has appeared on the building materials market — Euro -shifer. Its shape remained the same — wavy sheets, but the material is already different: bitumen. Hence — and the name of the roof: non -intestine slate. For laying the roof now use natural slate (natural slate).
