We hired GH Roofing in 2010 to install a new roof on our home. They used GAF roofing materials and non-code methods of installation (i.e., staples, incorrectly utilized) when nails were required. They did not take out a permit with the county. They were very slow, if not unresponsive at times, when we called starting in 2014 with concerns over leaks, etc. They were very difficult to work with, not customer service oriented at all, and totally unconcerned about our developing leaks and problems with an almost new roof. Dont use them...They don't stand behind their workmanship nor their materials.
