Cool Roofing Materials Database

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.

Cool roofing is not an entirely new concept. Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. A product of the cool colored roofing materials project a california energy commission sponsored collaboration between lawrence berkeley national laboratory oak ridge national laboratory and their 16 industrial partners. The cool products found on the crrc rated products directory in this category refer to the properties of the capsheet.

Residential roofing options include asphalt shingles metal clay tiles and concrete tiles. There are different cool roof standards for commercial low slope roofs and residential steep slope roofs. Commercial cool roof options include bright white membranes and white coatings.

Just as wearing light colored clothing can help keep you cool on a sunny day cool roofs material that is designed to reflect more sunlight and absorb less heat than a standard roof. The cool roofing materials database was created in 1998 and may not be current. Energy efficient roofing systems can reduce roof temperatures significantly during the summer and thus reduce the energy requirements for air conditioning.

The cool roofing materials database was created in 1998 and may not be current. We suggest you examine the relative coolness of various types of building materials to select a type of roofing or roof coating which may meet your needs to reduce air conditioning energy use or to improve comfort. Built up roofing bur consists of built up layers of coated asphalt and insulation applied on site and can be covered with a capsheet or surfacing material. Researchers have been studying materials that can reduce solar reflectance and thermal emittance for decades if only so that energy consumption due to cooling buildings could be reduced.

Built up roofing includes asphalt and coal tar pitch.
