Roofing Rules in Wisconsin: What Milwaukee, WI Homeowners Should Know
Wisconsin sets a short list of rules for roofing jobs, and the City of Milwaukee, WI adds a few of its own. This page gathers them in one place for owners of houses, duplexes and Polish flats across Milwaukee County, so you know what to ask a roofer before you sign anything.
Short Version
Wisconsin has no license made just for roofing, but whoever pulls a building permit on a one- or two-family home needs the state's Dwelling Contractor credential. A roofer may not promise to cover or refund your insurance deductible, not even in an ad. You get three business days to cancel after your insurer denies the claim in writing, and a separate three-day window applies to many sales made at your home.
This is a summary of public law, not legal advice. Sources were read on October 10, 2026, and laws change, so check the links below before relying on any point.
What WI Requires of Roofers
The state's rule is narrower than a trade license. Anyone who pulls a building permit for a one- or two-family dwelling needs a Dwelling Contractor credential, issued by the Department of Safety and Professional Services and backed by a Dwelling Contractor Qualifier. An owner who lives in the home and does the work is the one exception. You can look up any company on the state's license lookup.
The City of Milwaukee adds its own layer: contractors who take out permits for work in the city need a City license on top of the state credential. Since most house re-roofs there need no permit, that rarely comes up on a single-family or duplex job. It does on a building of three to six units, whose roofing permit requires the City's home improvement contractor license.
A written contract is required when you pay before the work is finished or the sale began away from the seller's place of business. It has to spell out the job, the materials, the price and when work begins and ends, and the seller must say which permits apply. Ask for lien waivers as you pay. The state sets no deposit cap, so spread payments across the job and hold a fair share until the roof is done.
- The state credential, checked by you. Ask for the Dwelling Contractor credential by name and search the company online before signing.
- Coverage on paper. Get proof of the roofer's liability insurance and its workers' compensation policy.
- A scope that fits the building. On a duplex or Polish flat, the full roof and both units' gutters belong in the written scope, along with ice-and-water shield at the eaves and valleys.
What the Deductible Law Says
Under Wisconsin's roofing-contract law, a roofer may not promise to pay or rebate any part of your insurance deductible, and the ban covers advertising too, so a flyer or web page hinting at deductible help is already over the line. The deductible is your share of a covered loss, and it stays yours to pay. Giving an insurer false information about a claim can amount to insurance fraud. Check your declarations page as well: some policies carry a separate wind or hail deductible.
The same law keeps roofers out of the bargaining. A roofer can't represent you or negotiate the settlement, though it can inspect the roof, photograph what it finds and write an estimate you may share. To have someone negotiate for you, hire a public adjuster, overseen by the Wisconsin Office of the Commissioner of Insurance, or an attorney.
- An offer to absorb the deductible. State law rules out any pitch to pay, rebate or "work out" your deductible.
- Cash only, or the whole price before work begins. Large upfront demands leave you little leverage if the job stalls.
If the Insurer Says No
Wisconsin gives you two separate ways out of a roofing contract, and each lasts three business days.
The first applies when the job depends on an insurance claim. If your insurer turns the claim down, fully or partly, you may cancel within three business days after receiving the insurer's notice. The contractor must give you a cancellation form, and any money you paid has to come back within 10 days.
The second covers a sale over $25 made at your home or anywhere away from the seller's place of business. It holds whether or not insurance is involved, which matters most when someone knocks on your door after a storm. Cancel in writing, and keep dated copies of the contract, the form and the insurer's letter together.
Storm-Resistant Roof Programs
This site knows of no Wisconsin state grant for storm-resistant roofs. Certain insurers reward impact-rated (Class 4) shingles with a credit under their own rules, and yours can tell you whether it does before you choose.
A change may also be coming: a 2025 Wisconsin law adds rules for contracts that transfer insurance benefits to a contractor and is reported to take effect December 1, 2026, so ask your insurer before signing anything that hands your claim rights to a contractor.
Inside City Limits
Inside the City of Milwaukee, tearing off or covering over the roofing on a house with one or two units generally requires no building permit, provided the rafters and other framing are left alone. The City's checklist lists re-shingling as a "maybe", so it is worth checking your job with the Permit & Development Center in the Department of Neighborhood Services (414-286-8210) or the City permit pages. Three- to six-unit buildings are different and need a roofing permit. A house in a historic district can also need a Certificate of Appropriateness for outside changes, permit or not, so ask whether yours sits in one before picking a new material.
Suburbs run their own offices and rules, and none should be assumed to match Milwaukee's:
- Wauwatosa, WI. The Building & Safety Division (414-479-8907) generally treats a like-for-like re-roof as maintenance with no permit, but switching to a different style of material, such as metal over asphalt shingles, needs one. Contractors on one- and two-family homes need valid state credentials.
- West Allis, WI. Its re-roof rule wasn't confirmed here, so ask the City of West Allis building inspection office about your job before any work begins (city line 414-302-2489).
- Oak Creek, WI. Inspection Services (414-766-7002) lists re-roofing among its residential alteration permits, so confirm with Inspection Services first.
- Mequon, WI. In Ozaukee County, the Inspections Department (262-236-2924) needs no roofing permit unless there are structural changes, but more than two layers of shingles require structural calculations. Contractors need state Dwelling Contractor and Qualifier numbers.
- Menomonee Falls, WI. The village's Building Inspection Division (262-532-4200), in Waukesha County, requires a building permit to re-roof and allows only two layers of roofing.

Questions About the Law
Can I re-roof my own house without the state credential?
Yes, if you own the one- or two-family home, live there and do the work yourself. Whether a permit applies is a separate question. Inside the City of Milwaukee most like-for-like house re-roofs need none, but the Permit & Development Center has the final say, and each suburb answers for its own addresses.
My insurer paid for only part of the damage. Can I still cancel?
Yes. The cancel right covers a denial in whole or in part. You have three business days after the insurer's notice to cancel the roofing contract, using the form the contractor had to give you, and any payments must be returned within 10 days.
Where do I take a complaint about a roofer?
Problems with contracts, deposits or sales tactics belong with the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP). Questions about a company's Dwelling Contractor credential go to the Department of Safety and Professional Services. Permit questions for a property inside the City of Milwaukee go to the Department of Neighborhood Services.

Questions About the Rules?
To get the scope, the permit answer and the price in writing, send a request through the form. One independent local roofer in the Milwaukee County area receives it, arranges a visit and writes the estimate. The roofer covers the cost of each referral, so the form costs you nothing, and no payment or perk comes back to you.
