GAF

GAF is North America's largest roofing and waterproofing manufacturer, with a history stretching back to its founding in 1886. The company's products protect more homes and businesses across the United States than any other roofing brand, a position built over more than 135 years of operation. Its core technical domains are roofing technology and waterproofing, serving both residential and commercial markets.

The firm has a long record of product development. It introduced ready-to-lay asphalt roll roofing in 1892 and reinvented its iconic GAF Timberline residential shingles in 1967. This sustained innovation is a noted aspect of its corporate identity, alongside a focus on American manufacturing excellence.

GAF's operations are concentrated in the United States and across North America. The company's stated purpose centers on protecting what matters most for its customers, a principle that underpins its work in the residential roofing, commercial roofing, and waterproofing sectors.
