            Extremely Fragile

Slate roofs are a premium option that is made mostly of natural slate tiles, as well as other roofing materials. Slate is mined primarily in Italy and is then cut into small, square tiles that are installed into a roof one tile at a time.

During the installation process, each tile must be handled extremely carefully as the tiles are fragile. Even after the installation process is complete, the tiles must be cared for diligently and delicately.


If your slate roof needs repairs after installation, it is especially important to hire a skilled roofer or someone who is trained to specifically work with slate tiles, as they can easily be damaged if not properly treated.
