Roof Repair in Castaic, CA

Sampling the official CAL FIRE maps puts about 88% of Castaic in a Very High Fire Hazard Severity Zone (about 59% on the State Responsibility Area map and 28% on the 2025 local map) and 98% in some zone. Across almost all of Castaic a replaced roof, or half of it or more within 12 months, must be Class A under the Wildland-Urban Interface Code, and metal sheets or shingles on a noncombustible deck count as Class A without separate testing. Metal roofing is among the roof searches from Castaic: metal roofing. Outside the State Responsibility Area land (about 61% of Castaic) and the High and Very High local zones, state law still requires at least a Class C fire-rated covering when more than half of a roof is replaced within a year (Health and Safety Code 13132.7).

Only 7.1% of Castaic’s 5,865 housing units were built before 1980, against 70.3% in Los Angeles County, and the median year built is 1992 (Census ACS 2024 5-year); 84.5% are detached houses and 83.1% are owner-occupied. A house from 1992 is now more than 30 years old.
