Summary

California Title 24 Part 6 requires cool roofing on most new and replacement low-slope roofs in Climate Zones 14 and 15, which cover most of Riverside County including the Coachella Valley and desert communities.

Full Breakdown

Riverside County Building & Safety enforces Title 24 cool-roof standards for residential and nonresidential roof replacements covering more than 50 percent of the surface. In Climate Zone 15 (Coachella Valley, Blythe, Desert Center), aged solar reflectance must meet or exceed 0.63 for low-slope roofs. Steep-slope residential roofs in Zone 15 require minimum aged reflectance of 0.20. Permits issued through the county TLMA portal, and inspectors verify Cool Roof Rating Council labels on shingles, tiles, or coatings. Solar PV roofs receive prescriptive credit.

Violations & Fines

Final inspection failure halts certificate of occupancy until compliant materials are installed or an alternative compliance pathway under Title 24 is documented.

Frequently Asked Questions

Do tile roofs qualify?

Yes. Many concrete and clay tiles meet aged-reflectance thresholds; verify the product is listed by the Cool Roof Rating Council.

Are HOA color rules a barrier?

HOAs may not unreasonably restrict cool-roof colors that meet Title 24 in Riverside County, though tile aesthetics often comply naturally.
