For more than 135 years, GAF has been protecting what matters most: the homes, businesses, and communities across North America. As the largest roofing and waterproofing manufacturer in the region, GAF has earned the trust of millions of property owners, contractors, and builders alike. In fact, 1 in 4 U.S. homes is covered by a GAF roof — a testament to the company’s quality, reliability, and innovation.
With over 30 manufacturing plants nationwide, GAF delivers products designed for real-world performance and backed by some of the strongest warranties in the industry. From residential shingles to commercial roofing systems, the company provides solutions that combine durability, style, and peace of mind.
But GAF is more than a roofing manufacturer. As part of Standard Industries, a global leader in industrial innovation, GAF is shaping the future of roofing with groundbreaking products like Timberline Solar® — the world’s first nailable solar shingle. This pioneering technology makes it easier than ever for homeowners to harness clean energy directly from their roof.
At its core, GAF believes in building more than roofs — it’s about building opportunity, sustainability, and stronger communities. Through initiatives focused on recycling, environmental stewardship, and workforce development, GAF is committed to creating a positive impact that lasts for generations.
When you choose GAF, you’re not just getting a roof — you’re gaining the confidence that comes with America’s #1 roofing manufacturer.
