Founded in 1886, GAF has become North America’s largest manufacturer of commercial and residential roofing. Our success in growing the company to nearly $3 billion in sales has been a result of our relentless pursuit of quality, combined with industry-leading expertise and comprehensive roofing solutions.

We are proud to be a global leader in insulation, roofing, and fiberglass composite materials. Our insulation products conserve energy and improve acoustics, fire resistance, and air quality in the spaces where people live, work, and play. Our roofing products and systems enhance curb appeal and protect homes and commercial buildings alike. Our fiberglass composites make thousands of products lighter, stronger, and more durable. At Owens Corning, we provide innovative products and solutions that deliver a material difference to our customers and, ultimately, make the world a better place.

The company was founded in 1951. It first manufactured building paper and then expanded to include coated roll roofing. Its first asphalt shingle was made in 1954, and the rest, as they say, is history. Today, more than 60 years after its founding, IKO has grown to be among the world’s largest exporters of asphalt shingles.

Since 1944, the TAMKO story has been one of innovation, quality and long-standing customer relationships. Though a lot has changed since we introduced our first shingle over 70 years ago in Joplin, Missouri, one thing remains the same: our commitment to constantly moving the industry forward with a wide variety of building products. Today, TAMKO remains headquartered in Joplin—the very place it first began—and operates additional manufacturing facilities and warehouse facilities across the country in order to serve its customers with roofing and building products.
