Report
Summit Roofing was a pleasure to work with. My sales rep Carl was extremely professional and very responsive to my questions. My contract price was the best price out of four companies I interviewed. When my job was started, the roofing team consisted of eight roofers and they were able to get the job done and cleaned up in one day -- in spite of the minor rain delay in the morning. My roof looks great and they went above and beyond with a lot of little extras -- like painting the rusty old vent for my microwave and removing a defunct attic fan from the roof. I would highly recommend Summit Roofing without question.

Thank you to Benny and Summit Roofing. They did a great job on our new roof and gutters with leaf guard! AND they were the lowest cost! Thanks again to Benny and the crews. And thanks for a nice clean up afterwards! Will definitely recommend Summit! Tim G Gainesville, VA
