In California, cool roofs are primarily defined by their performance characteristics and compliance with state building codes. According to state regulations like Title 24, a cool roof must utilize materials that possess high solar reflectance and high thermal emittance. These two properties allow the roof to reflect sunlight away from the building and release any absorbed heat more effectively than standard materials.
Specific qualifications and standards include:
Solar Reflectance Index (SRI): Materials must meet high SRI standards as recommended by the California Air Resources Board to combat urban heat islands.
Title 24 Compliance: For non-residential buildings, the code mandates specific reflectivity levels. Common compliant materials include specialized white paints, coatings, or single-ply membranes.
Product Certification: To qualify for financial incentives and rebates, such as those offered by the Riverside Public Utilities Energy Program, the products must be verified as energy-efficient cool roof coatings or materials during post-installation inspections.
These requirements ensure that the roofing system can reduce peak cooling demand by 11-27% and lower roof temperatures by up to 50 degrees Fahrenheit.
