Quick answer
Los Angeles County requires a building permit for re-roofs, and the same answer covers skylight and Solatube installation. Reroofing must comply with Chapters 7A and 15 of the Los Angeles County Building Code, the California Building Energy Efficiency Standards, and LACBC Section 1512, and the Building Official may allow an existing roof covering to remain only where there is no more than one layer of an approved covering type, the framing can carry the added weight, the deck is sound and dry, and the new covering matches the required pitch and fire classification for its location within the fire zone. Changing to a metal roof requires Department of Regional Planning approval. This is the unincorporated-county rule.

How to apply in Los Angeles County
In Los Angeles County, a residential reroof permit application is lighter than for structural work: you state whether the scope is a full tear-off (roof replacement) or an overlay (roof recover), describe the covering material and its manufacturer instructions, and note the condition of the existing deck, since those facts determine which code path applies.
What most roof replacement permit applications include:
- State on the application whether the job is a roof replacement, which strips all existing layers down to the bare deck, or a roof recover, which leaves the old covering in place under specific conditions, since the two scopes are governed differently (IRC R908.3).
- For Los Angeles County, a recover is only an option where the new covering follows the roof covering manufacturer's approved instructions or is a self-supporting system, such as standing-seam metal, that does not rely on the existing roof for support (IRC R908.3.1).
- Full tear-off must be scoped on the application instead of a recover when the existing roof is water soaked or deteriorated, is slate, clay, cement, or asbestos-cement tile, or already carries two or more layers of roof covering (IRC R908.3.1.1).
- For Los Angeles County, the materials and installation methods described on the application must comply with the reroofing requirements of the roof-assemblies chapter (IRC R908.1).
- If the scope reuses existing slate, clay, or cement tile, damaged or broken pieces cannot be listed for reinstallation, and any rusted or deteriorated flashings, edgings, outlets, or vents uncovered during tear-off must be scoped for replacement (IRC R908.5).

Inspections and closing out your permit
In Los Angeles County, most residential reroofs get two to three field inspections keyed to the scope of work: a deck or nailing check when sheathing is exposed or replaced, a final on the completed covering and flashings, and in some high-wind regions a dedicated check of mitigation measures added during tear-off.
- In Los Angeles County: where the covering is fully removed and the sheathing is exposed, replaced, or added, inspectors check the deck and its nailing before any new roofing goes down, since the structural framework must be able to carry the new covering's loads (IRC R908.2).
- In Los Angeles County: an overlay is only approved where it meets one of the code's listed recover conditions, such as installation in accordance with the covering manufacturer's approved instructions (IRC R908.3.1).
- In Los Angeles County: flashings disturbed or replaced during the job are checked against the approved manufacturer's installation instructions, and metal flashing that will receive bituminous material must be primed before installation (IRC R908.6).
- In Los Angeles County: a final inspection confirms the completed roof covering and its fasteners were installed as required for that material and per manufacturer instructions before the permit is closed (IRC R905).
- In Los Angeles County: in some regions with strengthened wind provisions, reroofing an older single-family home also triggers inspection of supplemental deck-nailing and a secondary water barrier added during tear-off, on top of the base reroofing requirements (Florida Building Code, Residential R908.7 Mitigation).
- In Los Angeles County: reinstalled existing slate, clay, or cement tile is checked against reuse limits at inspection, and any rusted, damaged, or deteriorated flashings, edgings, outlets, or vents found during tear-off must be replaced rather than reinstalled (IRC R908.5).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Los Angeles County permit portal or by phone at 626-458-3173.

- Where do you apply for a roof replacement permit in Los Angeles County?
- You can apply through the Los Angeles County permit portal or contact the Los Angeles County Public Works, Building and Safety Division directly. The links are listed on this page.
- Can a homeowner pull a roof replacement permit themselves in Los Angeles County?
- Under California law (Business & Professions Code 7044(a)-(b); Business & Professions Code 7031.5): California exempts an owner from contractor licensing under section 7044 when they personally perform all the work on their own property, or any work they do not perform themselves is done by their own employees paid only wages, and none of the improvements are intended or offered for sale. It also exempts an owner who directly contracts with licensed contractors for each trade, as long as no more than four of the single-family residential structures involved are intended or offered for sale in a calendar year; this route does not apply if the owner instead contracts with a general contractor for the construction. A homeowner may also improve their own principal residence without a license, as long as the work is done before any sale, they have actually resided there for the 12 months before completion, and they have not used this exemption on more than two structures more than once in any three-year period. Selling a self-built structure within one year of completion creates a rebuttable presumption that it was built for sale, which defeats the exemption, and selling five or more structures within a year makes that presumption conclusive. Separately, every city or county that requires a permit must also require the applicant to file a signed statement giving their contractor license number or the basis of their claimed exemption; a false or missing statement carries a civil penalty of up to $500. Confirm how Los Angeles County applies this before you apply.
