Roofing permits in Unincorporated Los Angeles County, CA

Short answer

Yes — a full or partial re-roof generally requires a permit in California. Code limits how many roofing layers may be overlaid before a tear-off is required, and Title 24 cool-roof rules apply to certain re-roofs by roof type and climate zone. Fees and whether a mid-roof inspection is required are set by the city. Roofing is generally done by a licensed C-39 contractor.
