Stockton enforces California Title 24 Building Energy Efficiency Standards which require cool roof products meeting specified solar reflectance and thermal emittance values for many residential and nonresidential roof projects.
California Title 24 Part 6 mandates cool roof performance for most low-slope nonresidential reroofs and for many steep-slope residential reroofs in Stockton, which sits in Climate Zone 12. Required Cool Roof Rating Council values vary by roof type and slope. Compliance is verified during building permit review by the Stockton Community Development Department. Exemptions exist for small reroof areas and specific assemblies meeting alternative compliance paths.
Installing non-compliant roofing without an approved alternative compliance path can trigger correction notices, failed inspections, and required removal or replacement.
