RCMA Announces Roof Coatings Category Rule


Roof coating manufacturers and other experts have developed a resource aimed at calculating and reporting the environmental attributes of roof coating materials.

The Roof Coatings Manufacturers Association (RCMA) along with NSF International, which is a third-party group that develops public health standards and certification programs, report that they have created the first product category rule (PCR) for roof coating materials in North America.

The PCR will enable product environmental information to be more transparent and useful to the marketplace, the groups said in a joint announcement Wednesday (Dec. 14).

Products covered in the PCR include fluid-applied and adhered coatings used for roof maintenance or roof repair, or as a component of a roof covering system or roof assembly.

The 43-page guide is available at this link.

‘Much Needed Guideline’

“This product category rule … provides our industry a much needed guideline for calculating and reporting the environmental attributes of roof coatings,” said Jim Kirby, executive director of RCMA.

RCMA is a national trade association that represents manufacturers of asphaltic and solar reflective roof coatings as well as suppliers to the roof coatings industry. 

“The subsequent life cycle analyses developed by our members using the PCR can provide a basis for improvement to enable reductions in environmental impacts over time,” Kirby noted. “We look forward to the positive impact this will have on the industry and those seeking more sustainable building products.”

The NSF International National Center for Sustainability Standards utilized an open consultative process to develop the roof coating material document with participation from an expert panel of RCMA members, suppliers, regulatory agencies, environmental organizations and end users.

Supplier Comment

Cleveland-based Sherwin-Williams Company participated in the PCR development as a manufacturer.

“We support our industry in providing more transparent and science-based information to our customers,” said Douglas P. Mazeffa, environmental project manager at Sherwin-Williams. “Our company is committed to helping customers make informed, environmentally-based purchasing decisions.”

What is a PCR?

A PCR defines how to conduct a life-cycle assessment for a product group and what to include in that group’s environmental product declaration (EDP) report. A life-cycle assessment measures inputs, outputs and environmental impacts of a product across its lifespan. The environmental product declaration (EPD) is the third-party-verified report that explains the data generated from a life-cycle assessment.

In the case of roof coatings, verified EDPs under the PCR will help architects and contractors identify products that meet certain sustainability goals and needs.

The roof coating PCR follows the same for architectural coatings, which was published in 2015. That PCR is available here.
