The Roofing Industry Has a Scam Problem. Here's What You Need to Know.
After a bad storm rolls through Northeast Wisconsin, two things happen fast: legitimate roofing crews get busy, and scammers show up at your door.
Roofing fraud is one of the most common home improvement scams in the country, and Wisconsin is not immune. The contractor who knocks on your door the morning after a hailstorm, gives you an enthusiastic handshake, and promises to "work with your insurance" might be exactly what they seem — or they might take your deposit and disappear. Or do the work so badly that you need another roofer to fix it six months later.
Either way, you're out money. And your roof is still a problem.
After 30 years of roofing in the Green Bay area, we've seen what these situations do to homeowners. This post breaks down the specific roofing contractor scam signs you should know, so you can spot an untrustworthy roofer before they have your signature on a contract.
Red Flag #1: They Showed Up Right After a Storm
This one isn't automatically disqualifying — but it's worth knowing what it usually means.
So-called "storm chasers" are contractors who travel from state to state following major weather events. They descend on neighborhoods with fresh hail or wind damage, go door to door, and sign as many jobs as possible before moving on. The business model depends on volume, not quality. They're often gone — sometimes out of state — before your insurance claim is even settled.
A local roofing contractor doesn't need to chase storms. They already live here. Their trucks say a local address, they have local references, and they'll still be in business next year if something goes wrong with your roof.
If someone shows up unsolicited after a storm and pressures you to sign immediately, slow down. A legitimate contractor is never going to tell you the deal expires today.
We covered the differences in more depth in our post comparing storm chasers vs. local roofers in Green Bay — worth reading before you talk to anyone.
Red Flag #2: They Ask for a Large Upfront Payment
Deposits are normal. Asking for 30–40% upfront before work begins is standard practice in the roofing industry — materials cost money, and contractors need some security before ordering product for your job.
But if a contractor asks for 50% or more before they've done anything, that's a problem. And if they ask for full payment upfront? Walk away.
Roofing scams almost always involve a large deposit. The contractor takes the money, orders cheap materials (or nothing at all), does minimal or no work, and then becomes very hard to reach. By the time you realize what happened, they're gone.
A reasonable deposit structure looks like: some amount upfront, a progress payment when materials are delivered and work starts, and the balance due at completion. That structure protects both sides. An all-upfront payment structure protects nobody but the contractor.
Red Flag #3: No Local Address, No Verifiable License
Wisconsin doesn't require a statewide roofing license, but contractors doing work over a certain dollar threshold need to be a registered home improvement contractor with the state. Beyond that, local municipalities may have their own requirements.
More practically: a legitimate roofing contractor has a physical business address. Not a P.O. box. Not just a phone number and a website. An actual location where they operate.
Before signing anything, look them up. Check the Wisconsin Department of Safety and Professional Services database. Look them up on the Better Business Bureau. Google the business name and see what comes up — not just their website, but reviews, complaints, news.
If you can't find any independent confirmation that this business exists and operates locally, that's a serious roofing scam red flag. Don't let a convincing pitch substitute for verifiable credentials.
For context: Pierce Roofing is Atlas PRO+ Platinum certified, carries $2 million in general liability insurance, and has operated in Green Bay for over 30 years. You can verify our certifications and credentials directly. Any legitimate contractor should be able to offer something similar.
Red Flag #4: The Estimate Is Suspiciously Low
Everybody wants to save money on a roof. That's understandable. But an estimate that's significantly lower than every other quote you got is not good news.
There are only so many ways to come in dramatically lower than the competition. Either the contractor is cutting corners on materials, they're planning to cut corners on labor, or the low number is a hook and the final bill will look very different once they're already on your roof.
All three of those outcomes are bad.
Quality roofing materials — shingles rated for Wisconsin's climate, proper underlayment, ice and water shield at the eaves — cost what they cost. Labor from skilled, experienced crew members costs what it costs. An estimate that doesn't account for those things honestly isn't a deal. It's a warning.
Get at least three written estimates for any significant roofing job. Compare them line by line, not just by total price. A contractor who can explain exactly what's in their estimate, why they chose those materials, and what their installation process looks like is a contractor who's probably doing things right. See what a thorough process actually looks like in our overview of how we approach every job.
Red Flag #5: They Pressure You to Sign Before You're Ready
High-pressure sales tactics are one of the clearest untrustworthy roofer signs there is.
"This price is only good today." "We have one opening left on the schedule this week." "If you don't decide now, we can't help you."
These are pressure tactics, and they're designed to short-circuit your ability to do your homework. A contractor who gives you an estimate and then needs your signature in the next hour is not confident in the quality of their work. They're confident that if you talk to anyone else, you'll discover a reason not to hire them.
Take your time. Get the estimate in writing. Compare it to others. Call references. Look at past work photos. A contractor who does good work is not going to evaporate because you took a few days to think.
Red Flag #6: No Written Contract, or a Contract With Vague Language
A verbal agreement is not a contract. And a contract that says "complete roof replacement" without specifying materials, underlayment type, manufacturer warranty terms, start date, or completion timeline is barely better.
Every legitimate roofing job should have a written contract that covers:
- The specific materials being installed (manufacturer, product line, color)
- What underlayment and ice barrier products will be used
- The scope of work — what's being replaced and what isn't
- Payment schedule with amounts and milestones
- Projected start and completion dates
- Workmanship warranty terms in writing
- What happens if unexpected issues are found during the job
If a contractor resists putting things in writing, or hands you a contract that's vague about the key details, assume the vagueness is intentional. Unclear contracts protect the contractor, not you.
Red Flag #7: They Want to "Handle" Your Insurance Claim
After storm damage, some contractors will offer to deal with your insurance company directly — sometimes even filling out paperwork on your behalf or inflating the damage claim to get a bigger payout.
This should concern you for two reasons.
First, insurance fraud is a crime. If a contractor submits an inflated claim and it comes back on you, you're the policyholder. Second, a contractor who's willing to be dishonest with your insurance company is probably willing to be dishonest with you.
Your insurance company should be contacted by you. The claim should reflect the actual damage. A legitimate roofing contractor can provide a detailed damage assessment, help you understand what your policy covers, and give you documentation to support your claim — without taking over the process or encouraging dishonesty.
Red Flag #8: No Proof of Insurance
This is non-negotiable. Any roofing contractor working on your home needs to carry general liability insurance and workers' compensation coverage. Full stop.
General liability covers damage to your property if something goes wrong. Workers' comp covers their crew if someone is injured on your roof. Without these policies, you could be personally liable for either scenario.
Ask for a certificate of insurance before work starts. The certificate should list your name and address as the certificate holder, and the coverage amounts should be meaningful — we carry $2 million in general liability coverage specifically because roofing projects involve real risk.
If a contractor hesitates or says they'll "get you that paperwork later," treat it the same as a firm no. Later doesn't protect you. The certificate in your hand before work starts does.
We go deeper on this issue in our post on why hiring a licensed and insured roofer matters — including what to look for on the certificate itself.
How to Avoid a Roofing Scam in Green Bay
The short version:
- Don't hire anyone who showed up unsolicited and is pressuring you to decide fast
- Get multiple written estimates and compare them in detail
- Verify the contractor's local address, insurance, and credentials before you agree to anything
- Never pay more than 40% upfront, and never pay the final balance until the work is done and you've inspected it
- Get everything in writing, including the warranty
If you've had a contractor approach you and you're not sure whether to trust them, the fastest way to get a second opinion is to call a contractor you know is legitimate and ask them to take a look.
