FAQs about GAF California Cool® Shingles
California’s Building Energy Efficiency Standards for Residential Buildings (Title 24, Part 6) contain requirements for the thermal emittance, three-year aged reflectance, and Solar Reflectance Index (SRI) of roofing materials used in new construction and re-roofing projects.
A cool roof is a roof that reflects more solar energy away from its surface and more efficiently radiates absorbed heat away from the building than other roofs. This helps air-conditioned buildings use less energy. You may want to install a cool roof to reduce building energy use, lower utility bills, improve the comfort inside the building, help reduce peak energy demand, and/or help combat local urban heat islands. Learn more about cool roof facts in our blog article Six Truths About Cool Roofs.
A cool roof is made of a material or has a coating that can lower the roof surface temperature, decreasing the amount of heat transferred into a residential or commercial building. Typically, roofs that are lighter in color or are reflective stay cooler than roofs that absorb sunlight. With GAF California Cool® shingles, homeowners no longer need to compromise on dark colors for reflectivity, thanks to EcoDark® granule technology. This technology provides both deep, rich color blends and reflectivity, allowing GAF to offer the darkest highly-reflective shingle color available: Timberline HDZ® RS in Charcoal.
