All Weather Roofing

As with any contractor, insist on a written estimate of all materials, work to be done, costs, and completion time frames BEFORE you part with ANY money. It would also be a good idea to confirm his valid public liability and property damage insurance, talk to others who he has worked for in the past, and compare his quote with other contractors' quotes for the same work. Make sure ALL the work is completed, ask about a written warrantee, and get a release of lien for materials used before making final payment.
