What is Cool Roof?
Roofing Glossary · Codes & Ratings
Definition
A roofing system specifically designed to reflect more solar energy and emit absorbed heat more efficiently than standard roofing, reducing roof surface temperatures by up to 50 degrees F on hot summer days. Cool roofs include white or light-colored membranes, reflective metal panels, and specially coated asphalt shingles. The Cool Roof Rating Council (CRRC) provides standardized testing for solar reflectance and thermal emittance ratings.
