Vegetated Roof System Assemblies (VRSAs) have become increasingly popular over the last decade as organizations seek to reduce the volume of storm water entering the sewer system, lower energy use and make their facilities more appealing.
Vegetative roofing systems have added a whole new level of complexity for the roofing contractor, even though the market for these products in the U.S. remains small.
The GAF Certified Green Roofer (CGR) program recognizes professional roofing contractors for a variety of sustainable business practices, including asphalt shingle recycling.
As part of the RoofPoint rating program for sustainable roofing systems, the Center has developed a unique approach to the selection of energy-efficient roof surfaces.
