The Pros and Cons of Slate Tile
Slate can be used for floors and roofs and gives your home an aura of prestige.
Slate tile is a popular roofing material with an air of prestige and a reputation for longevity. Although individual tiles sometimes crack, an entire roof made of slate will probably not have to be replaced for 50 years or more. Properly installed, slate also makes dependable flooring.
Slate is a metamorphic rock with relatively weak bonds between layers, so tile made from it tends to split along those planes. For an installation to resist damage, it must be set on a solid surface with mortar.
