State Roof Tile
Slate is a fine-grained rock derived from a shale-type rock composed of clay or volcanic ash. The word “slate” is also used for some objects made from slate such as tiles. Slate has two lines of breakability: cleavage and grain, which make it possible to split the stone into thin sheets. When broken, slate retains a natural appearance while remaining relatively flat and easily stackable.
Slate is particularly suitable as a roofing material as it has an extremely low water absorption index.
Slate roof tiles are usually fixed using either nail fixing, or the hook fixing method. Both these methods, if used properly, will provide a long-lasting weathertight roof with a typical lifespan of around 80-100 years.
