Being known as North America’s largest roofing manufacturer comes with responsibilities – to its customers, its contractors, and of course, to the environment.

Roofing Industry

GAF® is committed to being responsible stewards for the environment by promoting the wise use of resources for today and future generations’ roofing in Detroit, MI. GAF’s mission statement says that they “practice and support new technologies in energy efficiency, material optimization, and recycling that help conserve natural resources, and we share our knowledge to help our contractors, colleagues, and customers do the same.”

GAF’s sustainability efforts are manifested through their continuous support of different aspects of the industry:


EverGuard® TPO roofing is a “cool roofing” solution made of polypropylene. Cool roofing is designed to reduce energy consumption, which in turn reduces greenhouse gas emissions. GAF has produced more than 2 billion square feet of EverGuard as an alternative to EPDM and other membranous roofing material.

Each GAF facility has a volunteer Green Champion who monitors plant performance and promotes sustainability goals.

GAF’s Cool Roof Energy Savings Tool (CREST) is an online portal that helps contractors estimate energy savings for building owners. Once logged in, contractors can enter the specifics of a Detroit roofing project then receive a generated estimate afterwards. CREST has analyzed more than 24 million square feet total in proposed cool roof installations.
ShingleRecycling.org is created by GAF, the US EPA, and Construction & Demolition Recycling Association (CDRA) as the online resource for facilitating and promoting asphalt shingle recycling. Specifically, GAF has developed a mobile shingle recycling finder. Since 2010, 450 GAF Certified Green Roofers have recycled one million tons of roofing products.


The Certified Green Distributor™ Program is a web-based training and certification program for green building material distributors. It is the first — and so far only — program designed to train contractors’ sales personnel on the basics of green building science and green product knowledge, and how to apply it to roofing in Detroit.


In their commitment to advancing transparency in building products, GAF has completed two Life Cycle Assessments, and received two Environmental Product Declarations and four Health Product Declarations.
