Roof Replacement in Oklahoma City, OK

When replacement comes up

A repair handles isolated problems. Replacement becomes the conversation when:

• Damage is widespread across multiple sections of the roof
• The roof decking underneath is compromised in several spots
• The roof has already been re-covered with one layer of asphalt shingles over another
• Leaks keep coming back even after repairs

Oklahoma's statewide code generally doesn't allow a new layer of asphalt shingles over existing asphalt shingles. A complete separate roofing system, like a standing-seam metal roof that carries its own load, doesn't require removing the old roof covering. A roofer can tell you what applies to your situation.

Oklahoma rules that apply to a reroof

A few code points worth knowing before work starts.

Oklahoma adopted the 2024 International Residential Code statewide, effective September 14, 2026. It skipped the 2021 edition. Some city documents still cite older editions.

Oklahoma's code calls for a 36-inch ice barrier strip in roof valleys and where a roof changes pitch. Ice barrier along the eaves is not required in Oklahoma. The code also calls for a drip edge at the eaves and rake edges of shingle roofs, with an exception that means it doesn't always have to be metal.

Since August 1, 2025, the City of Oklahoma City requires a re-roofing permit for houses and duplexes when the work is over 500 square feet. A permit isn't required for maintenance of 500 square feet or less. After the work, city inspectors check the finished roof, including roof condition, flashing, drainage, installation and code compliance. Your roofer should pull the permit. The OKC Development Center is at (405) 297-2525. This rule follows city limits, not county lines.

Starting January 1, 2027, roofers doing home roofing in Oklahoma will need a new residential roofing endorsement from the CIB, with a grace period through January 1, 2028 for roofers already registered. To register, Oklahoma roofers must show general liability insurance and proof of workers' comp or an exemption, and every contract under the Roofing Contractor Registration Act must say that workers are covered by workers' comp.

Material choices worth asking about

A roofer can walk you through what makes sense for your home, but a few categories come up often in Oklahoma City, OK.

Impact-rated shingles are worth asking about given how often hail is reported here. UL 2218 rates roof coverings Class 1 to 4 by dropping steel balls, with Class 4, the top rating, using a 2-inch ball. In IBHS's 2025 shingle ratings, most of the 24 rated impact-resistant products rated Good and none rated Excellent. IBHS suggests choosing shingles rated Good or Excellent.

Metal roofing is another option. In a 2013 IBHS hail demonstration, standing-seam metal roofing dented but was not punctured. A standing-seam system also doesn't require removing the existing roof covering, as noted above.

FORTIFIED roofs and insurance discounts

If you are replacing a roof, it may be worth asking your insurer about the FORTIFIED standard before work begins.

Oklahoma law, since April 1, 2018, requires insurers to offer a wind and hail premium discount for homes built or retrofitted to the FORTIFIED standard, when the insurer finds it actuarially justified. The state does not set the amount, so ask your insurer what it offers.

The Oklahoma Insurance Department said in 2015 that a Class 4 shingle "generally receives the highest premium credit," and to check with your insurance company before you replace your roof to see what discounts it offers.

Oklahoma's Strengthen Oklahoma Homes program (Oklahoma Insurance Department) has offered grants toward FORTIFIED roof upgrades. You must apply and be approved before you pick a contractor or start work. Check oid.ok.gov/okready for the next application window.

If insurance is part of the picture

Two Oklahoma rules apply when a roofer's work is tied to an insurance payment.

Oklahoma law bars roofers from advertising or promising to pay any part of your insurance deductible. If a roofer does, your insurer doesn't have to consider that roofer's estimate (59 O.S. 1151.30). The Oklahoma Insurance Department's own guidance says: "Avoid contractors who offer to waive your deductible or promise a rebate (It's against the law!)."

If you sign a roofing contract to be paid by insurance and your insurer denies all or part of the claim in writing, Oklahoma law gives you the right to cancel within 72 hours of getting that notice. The roofer must provide a cancellation form with the contract (Oklahoma law, 59 O.S. 1151.21).

What affects the cost of a replacement

A roofer quotes based on the size and pitch of the roof, the material chosen, the condition of the decking underneath, the number of penetrations like chimneys and vents, and whether old material needs to be removed and hauled away. The CIB suggests getting at least three estimates so you can compare.

How to choose a roofer for a replacement job

Before you compare roof replacement contractors, check each one's registration. Oklahoma requires roofing contractors to register every year with the Construction Industries Board (CIB). Search the CIB's online roofing registration lookup or call 405-521-6550. Registered roofers must display their "OK" registration number on their trucks, business cards, contracts, bids and ads. Ask to see it before signing anything.

The CIB recommends getting at least three estimates, confirming registration first, asking for references from jobs over a year old, and getting a written contract before work begins. The Oklahoma Insurance Department says: never sign a contract with blank spaces, keep a copy, don't pay the full amount up front, pay in installments as work is completed, and hold the final payment until the job is done.

The Oklahoma Attorney General advises using a local company established in the community and being cautious of contractors who arrive uninvited or want large upfront or cash payments.
