It depends
Sometimes, depending on the project
Before reroofing a dwelling in a Wildfire Zone, reroofing a townhouse, installing building-integrated photovoltaic roof panels or other photovoltaic roof coverings, or reroofing with a material of dissimilar weight.

Quick answer
A straight like-for-like reroof of a Portland house does not need a building permit: the city lists reroofing with a roofing material of similar weight, including replacing some or all of the existing roof sheathing, as work that does not need a permit. A permit is required in three named situations: reroofing a dwelling in a Wildfire Zone, reroofing a townhouse, and installing building-integrated photovoltaic solar roof panels or other photovoltaic roof coverings. There is no size or dollar threshold; the trigger is the location, the building type, and the roofing material.

What a roof replacement permit costs in Portland
How to apply in Portland
In Portland, 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 Portland, 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 Portland, 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 Portland, 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 Portland: 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 Portland: 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 Portland: 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 Portland: 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 Portland: 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 Portland: 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 Portland permit portal or by phone at 503-823-7300.

- Where do you apply for a roof replacement permit in Portland?

- Can a homeowner pull a roof replacement permit themselves in Portland?
- Under Oregon law (ORS 701.010(7); ORS 701.325(1), (2), (3)): A homeowner may pull the permit and do the work. ORS 701.010(7) exempts from Construction Contractors Board licensing a person performing work on property that person owns, or on that person's own residence whether or not they own it, so no CCB license is needed to act as your own builder. That exemption does not cover someone working in the pursuit of an independent business with intent to offer the structure for sale. Oregon does require a signed disclosure at the counter: ORS 701.325(1) makes every city, county, or state permit office collect a written statement signed by the applicant, and an applicant claiming a licensing exemption must state the basis for it. ORS 701.325(2) requires the office to give the applicant the Information Notice to Property Owners About Construction Responsibilities and withhold the residential building permit until the applicant signs a statement, one option of which is that they are performing work on property they own or a residence they live in or will live in, and that any contractors they hire will be CCB licensed and properly endorsed. The Information Notice itself is a CCB rule form under ORS 701.325(3) covering payroll tax, workers' compensation, and liability and property damage insurance responsibilities. Confirm how Portland applies this before you apply.
