How we are making it healthier
GAF is a founding manufacturer of the Health Product Declaration since 2011 and has supported the launch of the HPD Open Standard and HPD Collaborative.
GAF is the only roofing manufacturer to publish Health Product Declarations (HPDs) on our TPO and ISO products, which means there are no secrets about the materials you’re using on your roofing project.
GAF EverGuard Extreme® TPO is the only roofing product to receive a Material Health Certificate, awarded by the Cradle to Cradle Products Innovation Institute at the Silver level — no hidden secrets here, either.

This product does not contain any ingredients on the Living Building Challenge Red List.
