Cool Roof Rating Council Compliant Products

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. For more information, visit their website at www.coolroofs.org

*CRRC Rapid Ratings: These are interim laboratory-aged values that simulate weathered values. These values will be replaced with the measured three-year aged values upon completion of the weathering process. SRI values calculated using Rapid Ratings may change once the aged rating replaces the interim rating.
