Oregon Roofing Permits & Storm Damage Repair Compliance Guide
In Oregon, roofing replacements and storm damage repairs are strictly governed by the Oregon Residential Specialty Code (ORSC) 2021 and enforced by local Building Codes Division (BCD) offices. Architects must verify jurisdiction-specific amendments—especially in high-wind zones like the Coast Range or hail-prone areas near the Columbia Gorge—and ensure all work complies with mandatory structural, weather-resistive, and licensing mandates before permitting.
Permit Requirements for Roof Replacement in Oregon
All roof replacements in Oregon require a building permit issued by the local jurisdiction’s Building Codes Division (BCD) office—whether full tear-off or overlay over one existing layer. Under ORSC 2021 Section R907, permits are mandatory for any reroof exceeding 25% of the roof area or involving structural modifications. Exceptions are extremely limited and do not apply to storm-damaged roofs requiring repair or replacement. Applications must include manufacturer-approved assembly details, fastener schedules, and documentation of compliance with wind uplift testing per ASTM D3161 Class F or ASCE 7-22 design pressures. Local jurisdictions—including Portland, Eugene, and Bend—may impose additional requirements, such as energy compliance forms (e.g., attic ventilation calculations) or historic district review. Failure to obtain a permit voids warranty coverage, invalidates insurance claims, and triggers mandatory correction orders during resale inspections. Architects must confirm jurisdictional thresholds (e.g., some counties allow overlays only if the existing roof is sound and meets current deck attachment standards) and submit sealed drawings when structural framing changes are involved.
Wind and Hail Uplift Standards & Local Amendments
Oregon enforces wind uplift requirements under ORSC 2021 Section R905.4, referencing ASCE 7-22 design loads and mandating minimum ASTM D3161 Class F (110 mph) or ASTM D7158 Class H (120 mph) performance for asphalt shingles in most climate zones. Coastal counties (Clatsop, Tillamook, Lincoln) and high-exposure sites—including ridgelines above 2,000 ft elevation—require ASCE 7-22 Category II or III uplift design verified by engineered fastening schedules. Hail resistance is addressed via local ordinances: Multnomah County requires Class 4 impact-rated materials for all new residential roofs post-2022, while Deschutes County mandates Class 4 in designated hail corridors identified by the Oregon Insurance Division. Architects must specify uplift-tested assemblies—not just product ratings—and validate fastener type, spacing, and substrate attachment depth per manufacturer installation instructions and ORSC Table R905.2(1). Field verification during BCD inspections includes spot-checking fastener penetration into solid wood framing (minimum 3/4” into rafters) and proper underlayment lapping. Noncompliant installations risk rejection at final inspection and liability exposure.
Ice-and-Water Shield Zones & Weather-Resistive Barriers
ORSC 2021 Section R905.2.7 mandates ice-and-water shield (IWS) underlayment in defined eave and rake zones across all Oregon climate zones, regardless of snow load. The required zone extends 24 inches inside exterior walls from the eaves and fully covers valleys, dormers, skylights, chimneys, and roof-to-wall intersections. In Climate Zone 4 (most of western Oregon), IWS must also cover the entire roof deck beneath metal, tile, and slate systems per ORSC R905.1.2. All IWS must comply with ASTM D1970 and be installed with minimum 6-inch side laps and 2-inch end laps; self-adhering membranes require substrate temperatures ≥40°F during application. For steep-slope roofs, breathable synthetic underlayments meeting ASTM D226 Type II or ASTM D4869 Type IV may substitute IWS outside mandated zones—but never replace it within them. Architects must detail transitions between IWS and wall WRBs per ORSC R703.4, ensuring continuous drainage plane integration. BCD inspectors routinely reject installations where IWS stops short of penetrations or lacks proper flashing integration, triggering costly rework. Documentation of IWS square footage and manufacturer submittals is required at permit intake in jurisdictions like Salem and Medford.
Insurance Claims, Contractor Licensing & BCD Inspection Process
Oregon law (ORS 701.001–701.990) requires all roofing contractors performing work over $1,000 to hold an active CCB (Construction Contractors Board) license with Roofing classification (CCB # prefix 'R'). Architects must verify license status and bonding via ccb.state.or.us before authorizing work—unlicensed contractors invalidate insurance claim payouts under ORS 746.205. For storm damage claims, carriers require a signed, CCB-licensed contractor estimate and BCD-issued repair permit before releasing funds; many insurers (e.g., Foremost, Safeco) mandate third-party engineering reports for wind/hail losses exceeding $15,000. The BCD inspection process includes three mandatory stages: rough-in (deck attachment and underlayment), pre-cover (flashings and valley metal), and final (completed roof with clean-up verification). Architects should schedule inspections 48+ hours in advance via the local jurisdiction’s online portal (e.g., Portland’s eTRAKiT or Lane County’s Accela). Post-inspection, BCD issues a Certificate of Compliance—required for title transfer and mortgage underwriting. Failure to pass final inspection triggers a Notice of Violation, requiring reinspection fees and potential civil penalties up to $5,000 under ORS 455.415.

Get Oregon Roofing Compliance HelpFrequently Asked Questions
Does Oregon allow roof overlays without a permit if only one layer exists?
No. ORSC 2021 Section R907.2 explicitly prohibits overlays without a permit—even over a single existing layer—if the work exceeds routine maintenance. A permit is required for any reroof, including overlays, to verify deck integrity, attachment compliance, and underlayment continuity per R905.2.
What wind speed zone applies to my project in Hood River County?
Hood River County falls under ASCE 7-22 Wind Speed Map Region C (115 mph ultimate design speed) with Exposure Category C. Per ORSC 2021 R905.4, this requires ASTM D7158 Class H (120 mph) uplift-rated assemblies and engineered fastener patterns verified by a licensed Oregon structural engineer.
Can a general contractor pull the roofing permit if they subcontract to an unlicensed roofer?
No. ORS 701.035 prohibits general contractors from delegating roofing work to unlicensed entities. Only CCB-licensed roofing contractors (classification 'R') may perform, supervise, or sign off on roofing installations—and they must hold the permit or be listed as the responsible party on the general contractor’s permit.
