This page lays out what the state, the City of Dayton and nearby offices say, with every source listed at the bottom.

Ohio has no state license for people who roof houses, so checking a roofer is your job, and paperwork is the best tool you have. Inside Dayton city limits, putting on new shingles needs no building permit, while any repair to the wood sheathing, rafters or trusses does. A contract you sign at home usually comes with a short cancel window. Ohio has no deductible law yet and adds no special exit when an insurer turns down a claim, and your insurance claim belongs to you and your insurer.
This is a summary of public law, not legal advice.
Verifying a Roofer
No state board in Ohio licenses residential roofers. Montgomery County's building office says state licensing isn't needed for contractors who only do one-, two- and three-family homes. The City of Dayton's contractor registration lists electrical, plumbing, pipe-laying and warm-air heating firms, and roofing isn't on it. Centerville registers electrical, fuel gas, HVAC and plumbing contractors and stops there. Fairborn asks contractors working in the city to register with it.
Since no title or badge settles the question here, look at what a roofer can hand you:
- Insurance you can see. A current certificate of liability insurance, plus proof of workers' compensation if the company has employees on your roof.
- An itemized contract. Materials, tear-off, disposal, start date, payment schedule and cleanup, all written down before anyone climbs a ladder.
- Two warranties on paper. One from the shingle or panel maker and one for the roofer's labor. Ask who registers the manufacturer warranty and keep the confirmation.
- A local address and references. A street address in the Dayton area and a few past customers you can call.
- A count of the old layers. Ask how many roofs sit on the house now. Two or more means everything comes off first.
- A plan for the decking. If the job may include new sheathing or rafter work, ask who will pull the permit and when.
The Ohio Attorney General's general advice fits a roof purchase well: put every promise on paper, weigh at least two bids side by side, and keep most of the money back until the roof is finished.
Deductibles and the Law
Right now Ohio law says nothing specific about roofers and insurance deductibles. HB 769, a bill the legislature is considering, would add rules on deductibles and on how roofers deal with claims. As of October 2026 it sits in a House committee, so none of it is law. Your deductible is your share of the deal you made with your insurer. When a roofer offers to swallow it, skip it or tuck it into the price, treat that as a red flag.
Who speaks for you on a claim. Ohio's Department of Insurance warns against signing power of attorney over to a contractor or letting one negotiate or settle your claim. In Ohio, the only person who can represent you on a claim for a fee is a public adjuster holding a certificate from the state. A roofer's useful part is smaller: inspect, photograph what's there and write an estimate you can share with your insurer.
When You Can Cancel
Ohio's Home Solicitation Sales Act covers many sales made away from the seller's place of business, such as a contract signed on your porch or at your kitchen table. In most of those sales you can cancel up to midnight on the third business day after you sign, and the contract must explain that right in bold type. Some sales fall outside the act, so read the cancel notice in your copy before you rely on it.
Ohio has no separate cancel period that starts when an insurer denies a claim, so take your time before signing, not after. Care here isn't idle worry: after the May 2019 Memorial Day tornadoes, the Ohio Attorney General sued contractors over roofing and repair work promised to Dayton-area families.
Storm-Resistant Roof Programs
Ohio has no state grant for new roofs or for storm-resistant shingles, and no Ohio rule requires them. Class 4 impact-resistant shingles are an option some Dayton homeowners choose because hail and strong wind arrive here most springs and summers.
Many insurers give a premium discount for a Class 4 roof, but terms differ by company and policy. Before you pick a shingle, ask your agent whether a discount applies and what proof they want, such as the final invoice.
Local Permit Questions
Which office covers your address matters more than your mailing city. Across Dayton, Kettering and the county-run areas, replacing shingles by itself doesn't call for a permit, while rotted decking or rafter repairs do. A few cities would rather hear from you first. The Residential Code of Ohio applies either way, and Dayton designs roofs for a 20-pound-per-square-foot snow load, one reason for the two-layer limit.
- City of Dayton. Division of Building Inspection, 371 W. Second St., Dayton, OH 45402, 937-333-3883. Per the City, a fresh layer of shingles goes on without a building permit; work on sheathing, rafters or trusses requires one. A roof that already has two or more layers must be stripped first.
- Montgomery County townships and contract cities. Montgomery County Building Regulations, 451 W. Third St., 937-225-4622. Its written policy: no permit for a tear-off or re-roof without structural repairs, and eave ice protection that runs from the edge to a point 24 inches or more inside the exterior wall line.
- Kettering, OH. City Planning & Development, (937) 296-2400. The City's re-roofing guide says a residential re-roof needs no permit or inspection, though the work still has to meet the Residential Code of Ohio.
- Huber Heights, OH. Building permits run through Montgomery County Building Regulations, 937-225-4622. The city and county pages describe roof work differently, so call the County before work starts.
- Beavercreek, OH. The City issues zoning permits only. Greene County Building Regulation, (937) 562-7420, handles building permits, asks for none on a re-roof without structural work, and requires an ice shield.
- Centerville, OH (Montgomery County). Building Inspection, 937-428-4786. The City hasn't published a re-roof rule, so call before work starts.
- Fairborn, OH. The City's own Building Inspection Division, 937-754-3050, covers Fairborn instead of Greene County. Its re-roof rule isn't confirmed, so call before work starts.
Rules FAQ
Does a roofer need a state license to work on my Dayton home?
No. The state has no residential roofing license, and Dayton's city registration is for electricians, plumbers and heating trades. That puts the checking on you: ask for a liability insurance certificate, workers' comp proof if there are employees, both warranties in writing and an itemized contract, then call a couple of references.
I signed a roofing contract at home yesterday. Can I back out?
Usually, yes. Under Ohio's Home Solicitation Sales Act, most contracts signed at home can be cancelled up to midnight on the third business day after signing. The contract itself should tell you how to cancel. Follow those printed steps, send your notice in writing and keep a dated copy for your records.
The roofer found rotten decking halfway through. Now what?
Inside Dayton, repairing or replacing sheathing, rafters or trusses needs a building permit from the Division of Building Inspection, 937-333-3883, even though the shingles alone didn't. Elsewhere, structural work brings in a permit from whichever office covers your address. Ask for a written change order that shows the added work and price before it goes ahead.
Where do I complain about a roofing job?
For a contractor dispute, call the Ohio Attorney General's Consumer Protection line at 1-800-282-0515. If you suspect insurance fraud, the Ohio Department of Insurance takes reports at 800-686-1527. Keep your contract, receipts, photos and any texts or emails, since both offices will ask what happened and when.
