A metal roof is a long-term investment. A properly selected and installed metal roofing system can provide a long service life, but that long lifespan only pays off when the roof is installed correctly, and installation quality comes down to the company you hire. Choosing the right metal roofing contractor in Metro Detroit is the single most important decision in the whole project, more important than the brand of panel or the color you pick.
The good news: you can vet a contractor methodically. This guide walks through how to confirm licensing through the State of Michigan, verify insurance, judge real metal-roof experience, and ask the questions that separate a specialist from a generalist. By the end, you will have a checklist you can use on every estimate you collect.
Why the contractor choice matters more with metal
Metal roofing behaves differently from shingles. Panels expand and contract with temperature swings, so fasteners, clips, and seams have to be detailed to allow that movement. Flashing at valleys, chimneys, and sidewalls is less forgiving than on an asphalt roof, and a standing seam system in particular relies on precise panel layout and concealed fastening to keep water out for decades.
An installer who mostly does shingle work can absolutely learn metal, but you want proof they already have. Metal installation shortcuts can show up years later as loose fasteners or leaks at penetrations, and by then the crew is long gone. Visible waviness in the flat areas of panels, sometimes called oil-canning, is a separate matter that can arise from several material, handling, substrate, design, and installation factors, so it is not by itself proof of poor workmanship. That is why “who installs it” carries more weight here than with a commodity roof. If you want a deeper look at how these systems are built, our page on standing seam metal roofing explains the components in plain language.
Step 1: Verify the license through Michigan LARA
In Michigan, residential construction licensing is handled by the Department of Licensing and Regulatory Affairs, known as LARA, through its Bureau of Construction Codes. LARA maintains a public license-verification tool, so you never have to take a contractor’s word for their credentials. You can search by company name or by the individual licensee and confirm the license is active and in good standing.
Here is the part many homeowners find confusing. Roofing work can fall under one of two license types in Michigan, depending on how the contractor is classified:
- Residential Builder license. This covers contractors who build or substantially improve residential structures. A full-service company that handles roofing along with other structural work often holds this license.
- Maintenance & Alteration (M&A) Contractor license. This is issued for specific trade categories, and roofing is one of the categories a contractor can be licensed for. A company focused on roofing may hold an M&A license in the roofing classification rather than a full builder’s license.
Either can be legitimate for a roofing project. What matters is that the company you hire holds an active, appropriate license and that roofing is within the scope of what that license covers. If you are unsure which applies, ask the contractor directly which license they hold and then confirm it yourself on the LARA portal.
One important clarification: the license is held by the company or its qualifying officer, not by every worker on your roof. It is normal and expected that a licensed company sends crews who work under that company’s license. So the question is not “is each installer personally licensed,” it is “is the company properly licensed and standing behind this crew.”
Step 2: Confirm insurance with a Certificate of Insurance
A license tells you a contractor is authorized to work. Insurance protects you if something goes wrong on your property. Before you sign anything, ask for a Certificate of Insurance, often called a COI, issued directly from the contractor’s insurance provider.
You are looking for two things on that certificate:
- General liability coverage. This responds if the contractor damages your home or a neighbor’s property during the job.
- Workers’ compensation coverage, where the contractor has employees. This matters because it helps protect you from liability if a worker is injured on your property.
Rather than fixating on a specific dollar figure, focus on whether the coverage is current and issued by a real carrier. A trustworthy contractor will have the certificate sent to you without hesitation. If you get pushback or delays on a simple insurance request, treat that as information.
Step 3: Judge metal-specific experience and local references
Plenty of metal roofing companies in Michigan can quote a job. Fewer can show you a portfolio of completed metal roofs in your area. Ask to see recent metal projects, ideally standing seam or the specific system you are considering, and ask where they are located. Local references are worth more than photos from another state, because you can drive by and, in some cases, talk to the homeowner.
When you check references, ask practical questions: Did the crew show up when they said they would? Was the site clean at the end of each day? How did the company handle any surprises found during the tear-off? Whether the project was a full roof replacement or a targeted metal roof repair, you want a track record you can actually verify.
The right questions to ask a metal roofer
Bring the same list to every estimate so you are comparing companies on equal footing. Strong questions to ask a metal roofer include:
- Which Michigan license do you hold, and can I verify it on the LARA portal?
- Can you send me a current Certificate of Insurance?
- How many metal roofs like mine have you installed in the last few years, and where?
- Which metal system and panel profile are you recommending for my home, and why?
- How will you handle flashing at the valleys, chimney, and any roof penetrations?
- What underlayment and ventilation approach do you use under metal in our climate?
- Who is the manufacturer, and what does the material warranty actually cover versus your workmanship warranty?
- Will your own crew do the work, or is any of it subcontracted?
- What does the written estimate include, line by line?
The answers matter, but so does the manner. A specialist will welcome these questions and explain their reasoning. Vague or dismissive answers are a signal.
Red flags to watch for
Most contractors are honest, but a few patterns should slow you down before you sign:
- Pressure to decide today, especially paired with a discount that “expires” immediately.
- Large upfront deposits for the full or near-full project cost before any material arrives.
- Reluctance to provide license or insurance details when asked plainly.
- No written, itemized estimate, or a quote scribbled on the back of a business card.
- A price far below every other bid. With metal, a rock-bottom number often means thinner material, a shortcut on flashing, or an inexperienced crew.
- Cash-only demands, or requests to pull the permit in your name so the contractor avoids accountability.
None of these alone proves bad intent, but two or three together is a reason to keep looking.
Why local, cold-climate competence matters
Metro Detroit roofs live through freeze-thaw cycles, heavy snow loads, and wind off the lakes. A contractor who works here every winter understands how snow behaves on metal, where ice tends to form, and how ventilation and underlayment choices affect performance in our climate. That regional knowledge is hard to fake and easy to verify by asking specific questions about local conditions.
A licensed metal roofing contractor in Michigan who works locally is also easier to reach if you ever need service. An out-of-town crew that installed your roof and drove home is not much help three years later.

Frequently Asked Questions
How do I verify a metal roofing contractor’s license in Michigan?
Use the public license-verification tool from Michigan LARA (Department of Licensing and Regulatory Affairs) through its Bureau of Construction Codes. Search by the company or licensee name and confirm the license is active and covers roofing. It takes a few minutes and costs nothing.
What license does a roofing contractor need in Michigan?
Roofing can fall under either a Residential Builder license or a Maintenance & Alteration (M&A) Contractor license in the roofing classification, depending on how the contractor is set up. Both can be valid. Ask which one the company holds, then confirm it on the LARA portal.
Does every installer on the crew need to be licensed?
No. In Michigan the license is held by the company or its qualifying officer, and crews work under that company’s license. Your job is to confirm the company is properly licensed and stands behind the crew doing your work.
What insurance should a metal roofing company carry?
Ask for a current Certificate of Insurance showing general liability coverage, and workers’ compensation where the contractor has employees. General liability protects your property, and workers’ comp helps shield you from liability if a worker is injured on the job.
How many metal roofs should a contractor have installed before I hire them?
There is no magic number, but you want a verifiable local track record with the specific system you are considering, such as standing seam. Ask to see recent Metro Detroit projects and speak with a reference or two rather than relying on a single number.
