Leveraging their extensive background in manufacturing and the roofing supplies industry from previous roofing underlayment companies, Great Asphalt Products (G.A.P.), launched in 1990 in Pryor, Oklahoma.

30 Years of Quality Manufacturing

2020 marks 30 years of manufacturing quality roofing and waterproofing products. As a family-owned company, we pride ourselves on our personalized service, product performance and ability to be nimble in an ever-changing market.

Our foundation was built on our Asphalt Saturated Organic Felts, but our growth is due to our extensive offering of the following products:

Since its inception, G.A.P. has expanded adding two more manufacturing facilities to service North America. G.A.P. is also vertically integrated by producing its own building paper in their paper mill. Manufacturing products to include saturated felt, roll roofing materials, synthetic underlayments, self-adhered modified bitumen underlayments for high-temperature applications and self-adhered base and cap sheets, G.A.P. is focused on producing the best quality roofing materials and providing the best-in-class customer experience.
