Why is slate a good type of rock to use for roofing singles?

Explanation:

Silicate minerals don't conduct electricity or conduct heat, so this makes slate a great material for roofing. It's also easy to create shingles out of slate. Because it's made of so many layers, it's a simple process to cleave off any number of these layers to create a shingle.
