GAF Manufactures Industry’s First Asphalt Shingles Containing Recycled Waste Shingles

This breakthrough represents an important milestone in providing more sustainable, affordable roofing materials and has significant implications for improving sustainability and circularity in the roofing supply chain.

“This latest innovation from GAF represents the first major step towards a circular economy for asphalt shingles,” said Jim Schnepper, President, GAF. “We envision a future where every homeowner can replace their roof with high-quality, affordable shingles made from recycled asphalt.”

The new shingle recycling process reduces the amount of raw materials needed to make new shingles without compromising product quality or performance. During the successful tests, GAF was able to recover more than 90 percent of its shingles waste material to be reused in the production of new clapboards. GAF has also demonstrated its ability to produce new shingles that contain up to 15 percent recycled content and are UL certified for their safety and effectiveness. The US Patent and Trademark Office has granted GAF ​​three patents for this new shingle recycling process.

GAF does more than $ 100 million to bring the recycling process to a commercial scale, including the development of a pilot operation in 2021 that will allow the company to conduct additional research and development on its process. Through the pilot, GAF expects to assess the maximum amount of recycled asphalt that can be used to make new shingles that meet the company’s high standards, while optimizing the manufacturing process before scaling across its operations.

“This innovation has the potential to reduce a significant waste stream in the US and represents an important step forward in the roofing industry,” said Tad Radzinski, Certification Officer, GreenCircle Certified, an external certification organization. “By recovering valuable end-of-life roofing materials, GAF sets the course to reduce the lifecycle environmental impact of a clapboard product and provide a truly circular, sustainable solution for roofing products.”

As a leading manufacturer in North America – with one in four residential roofs covered by GAF – the company is uniquely positioned to expand the impact of this innovation in manufacturing facilities to help reduce landfill waste and continue offering more sustainable roofing options to its customers.
