In episode 2 of Sustainacast, I sat down with Marty Grohman of GAF – America’s largest roofing manufacturer. In this discussion, we talked about where sustainability at GAF has developed from and where it’s headed.
We discussed the market reach and impact of GAF’s “Certified Green Roofer” program, and talked about various considerations in the world of roofing including recycling, insulation, vegetated roofing, rainwater harvesting and touched on some embodied energy conversations regarding different roof choices.
