The Cool Roof Rating Council (CRRC) administers a Rating Program under which companies can label various roof surface products with radiative property values rated under a strict program administered by the CRRC.
Highlights of the CRRC Product Rating Program include:
- ASTM Methods for both Solar Reflectance & Thermal Emittance
- Initial and Aged (three-year) Ratings
- CRRC Accredited Independent Testing Laboratories
- CRRC Approved Test Farm
- CRRC Licensed Sellers of Labeled Roofing Products
- Random Sampling Program for Verifying Label Compliance

About the Cool Roof Rating Council
The Cool Roof Rating Council (CRRC) is an independent and non-biased organization that has established a system for providing Building Code Bodies, Energy Service Providers, Architects & Specifiers, Property Owners and Community Planners with accurate radiative property data on roof surfaces that may improve the energy efficiency of buildings while positively impacting our environment.
