Dave was easily reachable. He was able to understand my roofing problem by phone and within a few hours his crew was at my home. The service charge was very reasonable. After repairs, it didn?t rain for several days. So D-Wing waited for several days to confirm that the rook leak stopped before sending the invoice. I will strongly recommend him for any roofing related work. D-Wing will be on my short-list for roof replacement work that I am planning to do in a few years.
