The Problem With Hiring a Roofer in Green Bay
Most homeowners only hire a roofer once or twice in their lifetime. That's not a lot of practice. And roofing contractors know it.
In a market like Green Bay — where hailstorms roll through every summer and ice dams knock out flashing every winter — the demand for roofing work is high and the bar to call yourself a roofer is low. Anyone with a pickup truck and a ladder can show up at your door the week after a storm and hand you a flyer. Some of them do fine work. Others disappear with your deposit.
Knowing how to choose a roofer in Green Bay means knowing what separates a contractor worth hiring from one worth avoiding. It's not about finding the lowest bid. It's about asking the right questions before you sign anything.
Here's what to ask.
Question 1: Are You Licensed and Insured in Wisconsin?
This is the starting point. Not optional, not negotiable.
Wisconsin requires roofing contractors to carry both general liability insurance and workers' compensation coverage. General liability protects your property if something goes wrong. Workers' comp protects you if a worker gets hurt on your roof — because without it, the injured worker can come after your homeowner's insurance instead.
Ask for the certificates directly. A reputable contractor will have them ready and won't hesitate to hand them over. The certificates should show current coverage dates and coverage amounts — for a job on your home, you want to see at least $1 million in general liability. Pierce Roofing carries $2 million.
If a contractor gives you a verbal "yes, we're insured" and then gets vague when you ask for documentation, walk away. We went into more detail on why this matters in our post on why hiring a licensed and insured roofer is non-negotiable.
Question 2: How Long Have You Been Operating in Northeast Wisconsin?
Local experience isn't just a marketing point. It genuinely matters for roofing in this region.
Northeast Wisconsin has specific climate challenges that out-of-state or out-of-region contractors don't always account for: ice dam risk from freeze-thaw cycles, wind uplift from Lake Michigan weather patterns, heavy snow loads that stress decking, and high humidity summers that accelerate moisture-related failures. A contractor who's spent 30 years building roofs in Brown County has seen all of it and knows how to build for it.
Beyond technical knowledge, local tenure also means accountability. A contractor who has operated in Green Bay for decades has a local reputation to protect. They're not here for one storm season. Their employees live in the area. Their kids go to school here. That's not nothing.
A company that set up shop last spring and hasn't made it through a full Wisconsin winter yet is a gamble, even if everything else looks good on paper.
Question 3: Do You Have References From Local Homeowners?
Ask for three to five references — not a portfolio of photos, actual names and phone numbers of homeowners in the Green Bay area who had similar work done in the past year or two.
Then call them.
Most people skip this step. Don't. A five-minute phone call with a past customer will tell you more than any website or sales pitch. Ask the reference:
- Did the crew show up on schedule?
- Was the final cost close to the estimate?
- Did they clean up after themselves?
- Have there been any issues with the roof since the job was done?
- Would you hire them again?
If a contractor can't produce local references, or if the references they give are vague and hard to verify, that's information worth having before you write a check.
Question 4: What Manufacturer Certifications Do You Hold?
This one separates the average contractors from the serious ones.
Major shingle manufacturers like Atlas, GAF, and Owens Corning have certification programs that allow select contractors to offer enhanced warranties — warranty coverage that goes beyond what the manufacturer offers to the general public. These programs aren't handed out to everyone. Contractors have to meet installation quality standards, train their crews, and maintain a track record of good work.
Atlas's highest tier is the PRO+ Platinum certification. Contractors at that level can offer the Atlas Platinum Protection Roofing System warranty, which includes coverage for both the materials and the workmanship. That's meaningful. A standard manufacturer's warranty only covers material defects. A workmanship warranty covers how the roof was actually installed.
Pierce Roofing holds Atlas PRO+ Platinum certification — one of fewer than a hundred contractors in Wisconsin who do. If you want to understand what that means in practical terms, read our full breakdown of the Atlas PRO+ Platinum certification.
When you're vetting a contractor, ask what certifications they hold and what warranties those certifications make available. A contractor who can't answer that question clearly probably isn't certified.
Question 5: What Does Your Warranty Actually Cover?
Warranties in roofing are frequently misunderstood — and occasionally misrepresented.
There are two distinct types. The manufacturer's material warranty covers defects in the shingles themselves. If a batch of shingles was manufactured with a flaw that causes them to fail prematurely, the manufacturer makes it right. That warranty travels with the materials, not with the contractor.
The workmanship warranty is different. That's the contractor's personal guarantee that the installation was done correctly. If a leak develops because of a nailing error or an improper flashing installation, the contractor fixes it at no charge. Most contractors offer one to two years. The better ones offer five to ten.
Pierce Roofing backs every job with a 10-year workmanship warranty. That's our stake in the ground.
When evaluating a contractor, ask to see both warranties in writing before you sign the contract. Verbal warranty promises mean nothing if the contractor isn't around to honor them.
Question 6: Will You Pull the Necessary Permits?
Roof replacements in Green Bay typically require a building permit. Some contractors skip this to move faster or avoid scrutiny. That's a problem for you, not for them.
If unpermitted work is discovered when you sell your home, you may be required to have the roof inspected or brought up to code before the sale closes. Some homeowner's insurance policies also exclude coverage for damage related to unpermitted work.
A legitimate contractor pulls the permit, schedules any required inspections, and handles that process as a normal part of the job. If a contractor tells you that permits aren't needed for your project, it's worth verifying that with the city directly before proceeding.
Question 7: Who Actually Does the Work?
Some roofing companies sell the job and then subcontract the installation to crews they've never worked with before. That's not always a problem, but it's worth knowing going in.
Ask whether the crew that will be on your roof is employed directly by the company or brought in as subcontractors. If it's subcontractors, ask whether those crews are verified to carry their own insurance. Ask whether a company foreman will be on-site during the job or whether you'll be dealing with a crew lead you've never met.
You have a right to know who is going to be working on your home. A contractor who treats that question as intrusive is telling you something.
Question 8: What's Your Process From Start to Finish?
A good roofing contractor can walk you through the entire project without hesitation. What happens on day one? How is the existing roofing removed? What does the decking inspection involve? How do they handle decking that turns out to be damaged once the old shingles are stripped? How long will the job take? What happens if the weather doesn't cooperate?
If a contractor fumbles through these questions or gives you vague answers, that's a signal. Not necessarily that they do bad work, but that they haven't thought carefully about process. And on a job that involves stripping your home's primary weather barrier down to bare wood, you want someone who has thought carefully about process.

Red Flags to Watch For During the Hiring Process
Beyond the questions, there are a few behaviors that should slow you down regardless of what the contractor says:
A quote delivered on the spot, same day as the first visit. Accurate estimates take time. A contractor who gives you a number before they've assessed the decking, measured the roof carefully, or checked local material pricing is guessing.
Pressure to sign before the storm damage estimate expires. This is a sales tactic, not a real deadline. Walk away from any contractor who creates artificial urgency around signing a contract.
Payment demanded upfront in full. A deposit is reasonable — typically 10 to 30 percent. Demanding full payment before work begins is a red flag that crosses into scam territory. We covered this and other contractor warning signs in detail in our post on roofing contractor red flags and scams.
No physical local address. If a contractor can't give you a verifiable local business address, they may not be as local as they claim.
One More Thing: Get Everything in Writing
The contract should include the scope of work, the materials with specific product names and specifications, the project timeline, the total cost, the payment schedule, and both warranty terms written out in plain language.
If a contractor resists putting something in the contract that they agreed to verbally, don't sign. Good contractors don't object to written agreements. It protects both parties.
