Roofing codes & requirements in Calabasas

Energy / cool roof (Title 24)

Calabasas sits in California Energy Commission Climate Zone 9. Under Title 24, Part 6, a low-slope or flat roof here must use a cool-roof product (aged solar reflectance of at least 0.63 and thermal emittance of at least 0.75 — roughly SRI 75) when you replace 50% or more of the roof or about 1,000 sq ft or more. Steep-slope (pitched) residential roofs in Climate Zone 9 are exempt from the cool-roof requirement, so standard shingle or tile is fine. Small like-for-like repairs generally don't trigger it. See the California Energy Commission standards and the CRRC directory for rated products.

Fire — Class A required (most parcels)

Most of Calabasas — including essentially all of its hillside and residential areas in the Santa Monica Mountains — is a Very High Fire Hazard Severity Zone (confirmed on CAL FIRE's 2025 map). There the building code requires a Class A roof assembly and ember-resistant vents (1/8-inch non-combustible metal mesh), and wood-shake roofs aren't allowed. Confirm your specific parcel. You can check any parcel on the CAL FIRE hazard-zone viewer.

Decking / sheathing

Many older Calabasas homes were built with spaced 1×6 “skip” sheathing under the original roof. For a modern shingle or tile system — and for a Class A assembly — that decking often has to be overlaid with solid sheathing, and any rotted boards replaced. We confirm exactly what your roof needs with a deck inspection at tear-off, not a guess.

Color & materials

Roof color isn't regulated by code. Where a cool roof is required you need a CRRC-rated product that meets the SRI — and those come in a wide range of colors, not just white.

Calabasas roofing FAQ

Common Calabasas roofing-code questions

Does my Calabasas roof need to be Title 24 cool-roof compliant?

Only on flat or low-slope sections. Calabasas is in Climate Zone 9, so Title 24 requires a cool roof (about SRI 75) when you replace 50%+ of a low-slope roof, but steep-slope shingle and tile roofs are exempt here.

Is Calabasas in a fire zone that requires a Class A roof?

Almost certainly — most of Calabasas, including essentially all residential and hillside areas, is a Very High Fire Hazard Severity Zone, so a Class A roof and ember-resistant vents are required and wood shake isn't allowed. Confirm your parcel on the CAL FIRE viewer.

Will my old spaced sheathing need to be re-decked?

Sometimes. Older Calabasas homes often have spaced 1×6 sheathing; a modern shingle or tile system (and a Class A assembly) may need solid sheathing over it. A deck inspection at tear-off tells us for sure.

Financing

Financing available for qualified Calabasas homeowners

You don't have to pay for a roof all at once: financing is available for qualified homeowners, subject to qualification — written itemized pricing first, financing second, never any pressure. And because Title 24 cool-roof products are qualifying energy improvements, a Calabasas re-roof that needs one may also qualify for PACE-style energy financing — ask us and we'll confirm what applies to your property.
