California roofing is shaped by two defining forces: wildfire risk in the state's vast Very High Fire Hazard Severity Zones (VHFHSZ), and Title 24 energy code requirements for cool roofs on most re-roofing projects. Whether you need a standard replacement, fire-rated Class A roofing in a high-risk zone, a Title 24-compliant cool roof, or storm damage repair in an atmospheric river year, The Home Service Guide connects you with licensed C-39 California roofing contractors in your area.
California's Very High Fire Hazard Severity Zones (VHFHSZ) cover millions of homes — particularly in the Bay Area hills, Los Angeles foothills and canyons, Wine Country, Sierra Nevada foothills, and San Diego backcountry. In VHFHSZ areas, Class A fire-rated roofing is required by California law (CA Building Code Section 705A). Class A materials include concrete tile, clay tile, metal, and Class A-rated composition shingles. Standard 3-tab asphalt does NOT qualify in VHFHSZ areas.
California's Title 24 Energy Code requires "cool roof" products on most residential re-roofing projects — roofing with a minimum Solar Reflectance Index (SRI) to reduce heat absorption and building cooling loads. Cool roof requirements apply to low-slope roofs statewide and steep-slope roofs in most CA climate zones. Your licensed contractor will specify Title 24-compliant products.
California requires roofing contractors to hold a C-39 Roofing Contractor license through the CA Contractors State License Board (CSLB). Always verify your contractor's C-39 license at the CA CSLB license check before signing. General contractors (B license) may also perform roofing in some circumstances — confirm scope with your contractor.
