The building owners contacted us to discuss the replacement of the entire roof system. They had been dealing with leaks caused by major ice damming and were looking for a solution that would not only address the leaks, but minimize the ice damming and heat loss. We installed several inches of polyiso insulation, resheeted the entire roof deck, and installed a GAF Golden Pledge Roof system complete with a 40 year material warranty and 20 year workmanship guarantee.
