California law on roof permits
California Building Code requires a building permit for most roof replacements, including re-roofing (tear-off and replacement) and certain repairs. The permit ensures work meets structural, fire safety, and energy code (Title 24) requirements. Skipping the permit is illegal and can create serious problems.
