1 · Product approvals

Product approvals

Oklahoma has no statewide roofing product approval or listing system. Local inspectors rely on the adopted IRC's labeling and standards requirements and on evaluation reports such as ICC-ES.

Code evaluation reports (ICC-ES, UL, IAPMO): 48 roofing reports

2 · Permit forms

City re-roof permits

No statewide re-roof permit rule; cities decide. Where a city does issue a permit, state law says permit officials must refuse it for unregistered roofing work and record the roofer's CIB registration number (59 O.S. 1151.3(F), 1151.17).

Oklahoma CitySince a June 17, 2025 ordinance, single-family homes and duplexes need a re-roofing permit ($94.50, often same day) before significant roof removal, repair or replacement; maintenance of 500 sq ft or less is exempt, and you upload photos and request a final inspection.NormanThe city's roofing FAQ says no permit is required for roofing work, but the work must meet adopted codes (including a one-layer limit for asphalt shingles) and the roofer must be CIB-registered.

Code rules

The Oklahoma Uniform Building Code Commission (OUBCC) adopted the 2024 IRC with state amendments, effective September 14, 2026 (OAC 748:20-6-1). It applies statewide; cities may enforce it with their own permit rules. Official adoption page ↗

Ice barrier mostly not requiredOklahoma's amendment to Table R301.2(1) says ice barrier underlayment is not required in Oklahoma except as provided in Section R905, so it applies only where the local jurisdiction marks a history of ice-dam damage.Drip edge on shingle roofsDrip edge is required at eaves and rakes of shingle roofs (R905.2.8.5). An Oklahoma exception allows a nominal 1x2 shingle mold instead of metal if the starter course extends 1/4 to 1 inch past it.Roof sheathing nailing by wind speedTable R602.3(1) footnotes set nail spacing for wood structural panel roof sheathing at edges and ridges by wind speed, and add the RSRS-01 ring-shank roof sheathing nail (ASTM F1667).

Wind, fire and storm programs

The Oklahoma Insurance Department runs Strengthen Oklahoma Homes, which pays FORTIFIED Roof upgrades. Many insurers file FORTIFIED wind/hail discounts, but no statute found mandates them.

Yes. Every roofing contractor, including subs and out-of-state firms, must register annually with the Construction Industries Board (CIB) under the Roofing Contractor Registration Act (59 O.S. 1151.1 et seq.). Commercial work needs a commercial endorsement; a residential endorsement is coming.

6 · Lien and contract forms

Lien and contract rules

Oklahoma's mechanic's lien law is in Title 42, but the official statute text could not be retrieved, so lien deadlines are not listed here. The roofing act adds contract rules for insurance-paid jobs.

72-hour cancellation after insurance denial (59 O.S. 1151.21)If the job is to be paid from an insurance claim and the insurer denies all or part of it, the homeowner may cancel within 72 hours of the written denial. Your contract must include a boldface notice and a detachable cancellation form; refund within 10 days, keeping only the value of emergency work.Written contract with workers' comp statementRegistered roofers must use a written contract (59 O.S. 1151.7), and the contract must state that all workers are covered by workers' compensation (59 O.S. 1151.22).Registration lapse lets homeowner cancelIf your registration is not in good standing you must tell the homeowner, who may then cancel and owes only the actual cost of materials and the market value of labor already done (59 O.S. 1151.5(I)).
