What Is a Slate Roof?

Slate roof tiles are a type of sedimentary rock formed from volcanic ash and clay.

Slate comes in a variety of colors due to the minerals that can be found inside of it.  For example, chlorite makes slate turn green. Other colors you may find are black, gray, purple, and red.

Based on what minerals are in the slate can determine if weathering or fading will occur. Weathering will slowly change the color of your slate when it’s exposed to the elements.
