California Title 24 building energy standards require cool-roof reflective materials on most new and replacement low-slope and many steep-slope roofs in Santa Ana's climate zone, reducing urban heat-island effects.
Santa Ana sits in California climate zone 8 under Title 24 Part 6. New construction and reroofing of low-slope assemblies generally must use materials meeting minimum solar reflectance and thermal emittance values certified by the Cool Roof Rating Council. Steep-slope residential reroofs may also need cool-roof tiles or shingles depending on insulation. Permits are issued by Santa Ana's Planning and Building Agency, and roofing contractors must file a Title 24 compliance form before final inspection.
Failed inspections delay certificate of occupancy. Unpermitted reroofing triggers stop-work orders and re-inspection fees from Planning and Building.
