The installers at Quality Discount Roofing were on time, very professional and did quality work. Several neighbors commented on the way they were very quiet (as quiet as you can be when removing and installing a roof). But they had no loud music on, didn't yell at each other during their work, and their compressors were not loud at all. After the roof was installed, they carefully removed all nails from the driveway, grass and flower beds. They also used a leaf blower to blow out all the debris in the gutters. My neighbors commented to me that their roofers did not do that which led to some problems with water remaining in the gutters. I would highly recommend Quality Discount Roofing, and would have them replace another roof whenever necessary.
