The owner of the company a large one in the area. Said it happens because of a trick of the trade and he does it himself and then that I should just accept it because it has become acceptible. When I tell him it is a sign of poor quality he laughed and said that they have the highest quality rating in the industry and basically I didn't know what I was talking about and I should just let him take care of the roof he personally is taking care of the job and going to make sure I'm happy.
