Before you hire

Slate roofer questions, answered.

How do I choose a qualified slate roofer?

Ask for recent natural-slate projects similar to yours, references, proof of insurance, applicable licensing and a clear explanation of the proposed repair or installation method.

Why does natural slate experience matter?

Slate roofing uses specialized layout, fastening, flashing and repair techniques. A contractor experienced with natural slate is better equipped to protect the roof and avoid unnecessary replacement.

What if no preferred company serves my area?

Send Slate Boss your project location, roof type and a short description, or call the Guild. The team can help identify an appropriate specialty company beyond the current preferred directory.
