About the Product Rating Program

Please note that participation in the CRRC Product Rating Program is separate and distinct from CRRC Membership. To learn more about becoming a member, please go to Become A Member.

The CRRC administers a Product Rating Program in which companies can label roof surface products with radiative property values. The CRRC does not set a minimum definition for "cool", the CRRC simply lists the measured radiative property values on our Directory.  Any roofing product can be tested as long as it is in compliance with the Product Rating Program Manual (CRRC-1). A product's placement on the Directory does not mean that the product is "cool" as defined by any particular code body or program. 

The Rapid Ratings Program, an optional product rating process which develops interim laboratory-aged values for roofing materials, allows LSs and OMs to list laboratory-aged radiative property values in the CRRC Rated Products Directory at an accelerated rate - the aging simulation is completed in less than a week! To learn more about CRRC Rapid Ratings or to submit a Rapid Ratings application, visit the Rapid Ratings page.

All radiative property testing is conducted by accredited testing laboratories and all laboratory-aged testing is conducted by approved CRRC Rapid Ratings laboratories (see CRRC Accredited Testing Laboratories (AITL and AMTL) for a list). Solar reflectance can be measured in accordance with ASTM test methods C1549, E1918, E903 and CRRC-1 Method #1: Test Method for Certain Variegated Products. Thermal emittance is measured in accordance with ASTM C1371.  For aged ratings, product specimens are exposed for three years at the CRRC Approved Test Farm. Product ratings are verified periodically through the CRRC's Random Testing Program.

About the Random Testing Program

Random Testing provides quality assurance of the Rated Products Directory by routinely testing that products are consistent and that the rated values reflect what is sold in the marketplace. Each year, a small percentage of products listed on the Rated Products Directory are randomly selected to go through the Random Testing Program. The longer that a product has been listed on the Rated Product Directory, or if a product was not selected in previous years, the more likely that product is to be chosen for Random Testing.

If your product is selected for Random Testing, procurement information will be requested from the product contact. Procurement information is required within two weeks of the initial notice. A third-party Quality Assurance Organization will then collect samples from the manufacturing facility and the samples will be tested by an AITL. The product will have three chances to pass within a ±0.05 margin of the initial solar reflectance and thermal emittance values. Licensees whose products are selected for Random Testing will pay no cost for the first two tests, but if a third test is conducted it will be at the expense of the licensee. If the product fails all three tests it will be removed from the Rated Products Directory.

For more information on the Randon Testing Program, see Chapter 3.6 of the CRRC-1 Product Rating Program Manual and Appendix 5: Random Testing Procedures.
