Roof Replacement Permit in Santa Clara County, California

Quick answer
Santa Clara County's adopted work-exempt-from-permit list under California Residential Code Section R105.2 contains eleven items covering sheds, fences, retaining walls, water tanks, sidewalks and driveways, finish work, shallow prefabricated pools, playground equipment, window awnings, small detached decks and hoop structures. Roof replacement is not among them, so Ordinance Code Section C1-67 applies and a building permit is required before the work is performed, and the county's fee schedule carries a dedicated flat reroof permit fee that confirms reroofs are permitted work. Fire rules bite hard here: the county amended California Building Code Section 1505.1.2 so that roofing for structures in Fire Hazard Severity Zones or the Wildland-Urban Interface must also comply with Part 7, Section 507.1 of the County Wildland-Urban Interface Code, which is the section governing replacement or repair of roof coverings.

How to apply in Santa Clara 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).
- 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).
- 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
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.
- 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).
- 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).
- 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).
- 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 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).
- 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 Santa Clara County permit portal or by phone at 408-299-5700.

- Can a homeowner pull a roof replacement permit themselves in Santa Clara County?
- Under California law (Business & Professions Code 7044(a)-(b); Business & Professions Code 7031.5): California exempts an owner-builder from contractor licensing when the owner personally performs the work, or uses only wage employees, on their own property and does not intend the improvements for sale. A homeowner may also directly hire licensed trade contractors for up to four single-family residences a year, or improve their own principal residence without a general contractor's license, as long as they have actually lived there for the 12 months before the work is finished. 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 building 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 $500 civil penalty.
