The roof on my central phoenix home was destroyed in the hail storm of Oct 5th, 2010. I received three estimates from different roofers in the area. Advance Roofing Systems was several thousands of dollars less than the others. I met with the owner Ken who was very professional and assured me that they would clean up their work area daily during the project. I have yet to find a roofing nail around the yard and the new roof looks fantastic! They not only replaced the attic vents on my roof but painted all vents, exhaust pipes and air conditioning duct to match. Many of my neighbors had their roofs replaced and not one of their contractors had this kind of attention to detail. Love my new "painted desert" roof!
