I had American roofing replace my roof 15 years ago, I am having the gables redone and they showed me what was not done when the roof was installed, NO Felt paper on the entire decking, the shingles were buckled and some of the plywood was not nailed down securely. I would not have them roof my dog house. I had to pick one star to post but it should be a -5 stars

Committed, customer-first experience. The crew arrived on time each day and worked hard. Our roof was completed in the time frame promised, and is guaranteed to last. Highly recommend.
