The Asphalt Roofing Manufacturers Association (ARMA) and its member companies have partnered with ASTM International to develop product category rules (PCR) for asphalt roofing in North America. The new free PCR will provide consistent methodologies for asphalt roofing manufacturers to measure and report the expected environmental impact of their products.
Asphalt roofing manufacturers can use these guidelines to review their own products and develop an environmental product declaration (EPD)—a verified document reporting the expected environmental performance of a material based on its expected lifecycle. An EPD uses the data collected through PCR guidelines to provide comparable environmental impact data for similar products.
“This PCR is a significant, universal resource for the asphalt roofing industry,” said ARMA executive vice president Reed Hitchcock. “It provides a way to collect, measure, and communicate data pertaining to expected product environmental impacts… and will give consumers and industry professionals new insight into asphalt roofing materials. Developing these guidelines helps further ARMA’s commitment to transparency and environmental sustainability.”
Titled “Asphalt Shingles, Built-up Asphalt Membrane Roofing, and Modified Bituminous Membrane Roofing,” the PCR covers asphalt shingles applied over underlayment, and low-slope roofing assemblies consisting of various combinations of factory-produced asphalt-saturated or coated base sheets, ply sheets, and cap sheets together with specified viscous asphalt coatings, adhesives and surfacings.
