California Title 24 & Cool Roof Requirements
California’s Title 24 Energy Code requires “cool roof” products (reflective roofing) for re-roofing projects in most climate zones, including San Jose (Climate Zone 4). Cool roof products have a minimum Solar Reflectance Index (SRI) of 16 or higher. Most modern architectural shingles and tiles meet this standard. Quartz Construction instates only Title 24-compliant materials.
