The elements had pretty much destroyed one side of my roof leaving the other side nearly new. I called George, he came over in 2days with a great quote for adding a new layer on one side ontop of the destroyed one, and then was here 2 days after that 7am. His crew continued the job the next day a total of 5.5hours including all cleanup. They use a silencer nail gun so on the outside it is not loud at all. Inside the noise is loud as to be expected. They work hard, answer calls and questions any time. They also do a great job and clean everything up after.
