Slate is almost a perfect roofing material- it is fireproof, mossproof, rust-proof, and never wears out. A well-built slate roof can last hundreds of years.
But installing slate shingles takes skill. For correct repair and installation work on slate roofs you need have special slate roof tools. At the minimum you’ll need a slate hammer and a slate cutter. For removing old slate shingles during repair work, you’ll also want a slate ripper.
The slate hammer is looks sort of like a mountain climber’s ice axe in miniature. The hammer head is used for nailing work and the 6 inch tapered tail for punching nail holes in slate shingles. They’re lightweight, about 14 ounces, since nailing slate must be done carefully.
