History OF CRRC

The Cool Roof Rating Council was created in 1998 to develop accurate and credible methods for evaluating and labeling the solar reflectance and thermal emittance (radiative properties) of roofing products and to disseminate the information to all interested parties.


The CRRC is incorporated as a non-profit educational organization for the following purposes:

  • To implement and communicate fair, accurate, and credible radiative energy performance rating systems for roof surfaces.
  • To support research into energy related radiative properties of roofing surfaces, including durability of those properties.
  • To provide education and objective support to parties interested in understanding and comparing various roofing options.

Product Rating Program

At the core of the CRRC is its Product Rating Program, in which roofing manufacturers can label various roof surface products with radiative property values rated under a strict program administered by the CRRC. Code bodies, architects, building owners and specifiers can rely on the rating information provided in the CRRC Rated Products Directory. For further information, please see the Product Rating Program page.


The CRRC's diverse membership includes anyone who is interested in rating roof surface radiative properties and in the energy efficiency of roofs. Our members include roofing manufacturers, suppliers, and distributors, as well as roofing contractors, consultants, non-profit groups, government agencies, educational institutions, air quality boards, code bodies, energy service companies and other interested individuals. For more information on how to become a member, please visit our Join the CRRC page.

Membership is distinct from the CRRC Product Rating Program. Membership is optional and not required to have a product rated, nor is it automatic if you get a product rated.


CRRC has two major committees reporting to the Council's elected Board of Directors. Both committees may have specific subcommittees or task forces to work on individual projects.

Technical Committee

Charged with understanding and resolving core science and technical issues such as standard ASTM methods, round-robin testing programs for Accredited Laboratories, and weathering test farm protocols.

Ratings, Codes and Standards Committee

Key liaison with local, state and national code bodies & decision-makers interested in understanding and using the CRRC Product Rating System in energy codes, energy efficiency initiatives and incentive/rebate programs.
