The Cost Can Be Worth It

Slate, in and of itself, is an expensive material. "Slate," according to BobVillacom, "with its need for skilled and experienced craftsmen, could cost up to $1,000 a square" In addition, because of the weight of slate, "if you want to roof with slate.
you will need the framing to match".
On average, repairs to a slate roof will cost in the area of $60 per square. More specifically, JenkinsSlatecom indicates that replacing just six to 12 tiles can cost around $42500.
