When you receive a roof replacement from Coastal Roofing, you're receiving an entirely new roof system. We don't just install new shingles on top of old materials. We completely remove your old roof down to your plywood decking. We do a very thorough inspection to make sure that the substrate of your roof is structurally sound, and we will address any repair or replacement of materials necessary. We are then going to use products designated by your manufacturer to ensure that you receive their full warranty.
