If you are hiring a roofer in Michigan, start with the license check. Michigan licenses residential roofing at the state level, so an unlicensed roofer is not legally allowed to do the work for compensation. After that, the job is to verify what you can verify: insurance, local track record, references, manufacturer certifications, and a written scope that tells you exactly what will happen on your roof. In Michigan, that matters because roofs get hit from both sides of the calendar. Heavy snow, lake-effect bands, freeze-thaw cycling, and ice dams stress the roof in winter. Then summer storms bring straight-line winds and hail that bruise shingles and strip granules.

Do roofers need a license in Michigan?

Yes. Michigan licenses residential roofing at the state level. Under Article 24 of Public Act 299 of 1980, a contractor doing roofing on homes must hold either a Residential Builder license or a Maintenance and Alteration (M&A) Contractor license carrying the roofing classification, trade code "M", issued by the Bureau of Construction Codes under the Department of Licensing and Regulatory Affairs, LARA. If someone says they do not need a license for residential roofing work, move on.

Ask for the contractor's license type and number, then confirm it is active through LARA's license lookup. This is the first screening step, not the last one. A license tells you they are legally allowed to do the work. It does not replace checking the scope, the crew plan, or the protection details that matter on a Michigan roof.

What should you verify besides the license?

Verify the things you can document before any materials are dropped off. In Michigan, a good hiring process is simple: confirm the active state license, ask for current general-liability and workers'-compensation insurance, review a real local track record and references, and look at the exact product and installation scope. If a roofer gets vague when you ask for paperwork, that is your answer.

• Ask for a Residential Builder license or an M&A Contractor license with the roofing classification.
• Confirm the license is active through LARA.
• Ask for current general-liability and workers'-compensation insurance.
• Ask for local references from recent roof jobs like yours.
• Ask whether the proposal includes manufacturer-certified products or installation requirements, and get the exact product names in writing.
• Make sure the written scope covers tear-off, decking, underlayment, ice-and-water shield at the eaves and valleys, flashing, ventilation, and cleanup.

What belongs in a written roofing scope in Michigan?

The written scope should answer how your roofer will keep water out, how they will handle hidden wood issues, and how they will leave the property when they are done. Michigan roofs fail where winter hits hardest, and the biggest cold-weather threat is ice dams. That means your scope should not just name a shingle. It should spell out the water-management parts of the system.

• Tear-off details: whether the roof will be fully torn off and what gets removed.
• Decking plan: how damaged decking is identified and handled if found.
• Underlayment details: what goes over the deck before shingles or metal.
• Ice-and-water shield at the eaves and valleys.
• Flashing details at chimneys, walls, valleys, skylights, and pipe penetrations.
• Ventilation details, including how intake and exhaust are balanced.
• Cleanup details, including debris removal and magnetic nail sweep.
• Material list with exact product names and shingle class, if applicable.
• Who handles permits, if needed, and what inspections are part of the job.
• Start conditions and on-site timeline expectations. For roofing contractor rules in Michigan, ask the contractor to put the expected working days and weather plan in writing; timing depends on roof size, material, access, crew scheduling, and conditions found after tear-off.

Ask one more Michigan-specific question: how does the proposal handle eaves, valleys, penetrations, air sealing, insulation, and balanced ventilation? In this climate, attic conditions and water protection matter as much as the shingle classification. A cheaper bid that skimps on these details can cost you more when freeze-thaw movement and ice dam backup start pushing water under the shingles.

How much should a new roof cost in Michigan?

Use 2026 market pricing as your baseline, then compare the scope line by line. For current Michigan planning prices related to roofing contractor rules, use the cost guide and calculator, then compare the contractor's property-specific written scope. For roofing contractor rules in Michigan, treat a steep or difficult-to-access roof as a scope variable that the contractor should measure and price explicitly.

Those numbers only help if you are comparing the same work. One estimate may include better flashing replacement, more ice-and-water protection, or ventilation changes, while another may leave those items vague. If you want a broader price check for your area, full local pricing lives on the Michigan cost page and the calculator. Use those as a baseline, then bring every quote back to the written scope.

Will Class 4 shingles lower your insurance premium in Michigan?

Sometimes, but do not build your budget around a discount until you have it in writing from your carrier. For roofing contractor rules in Michigan, any insurance credit depends on the carrier, policy, address, and exact product; get the amount and documentation requirements from the insurer in writing. The exact product and insurer treatment still need to be verified. In Michigan, hail is a concern in parts of the state, especially in the southern and southeastern counties, but impact resistance is only part of the picture.

Ask your roofer for the exact Class 4 product being proposed, then ask your carrier what documentation they require and whether your policy recognizes that product for a credit. Also ask whether your roof is insured at replacement cost or actual cash value, because payout rules can matter more than a possible premium change on an older roof.

What insurance rules should Michigan homeowners know before storm roof work?

Know your deductible before you file, and never sign a deal built around dodging it. For roofing contractor rules in Michigan, review the declarations and endorsements for any wind, hail, hurricane, or named-storm deductible. Ask the insurer to show the policy-specific calculation in writing instead of relying on a generic percentage. On a an amount that must be confirmed for the written scope home that can be an amount that must be confirmed for the written scope to an amount that must be confirmed for the written scope out of pocket before the insurer pays anything. Coverage also depends on whether your roof is insured at replacement cost or actual cash value. Some policies exclude purely cosmetic hail dents.

For roofing contractor rules in Michigan, do not assume a contractor can remove or hide the deductible required by the policy. Verify current state law and the written proposal with the insurer or state insurance regulator before signing. If someone pitches a free roof by covering your deductible, that is not a deal to chase. It is a contract to avoid. If a contractor solicited the job at your home, the Home Solicitation Sales Act gives you three days to cancel in writing. If a storm claim is wrongly denied or delayed, you can file a complaint with the Department of Insurance and Financial Services, DIFS, at michigan.gov/difs or 877-999-6442.

What are the biggest red flags when hiring a roofer in Michigan?

The biggest red flags are simple: no active state license, no clear paperwork, and no clear scope. In Michigan, a lot of roofing problems start before the first shingle comes off, when the homeowner agrees to vague promises instead of documented work. If the roofer will not slow down and put it in writing, you should slow down and keep shopping.

• They cannot show a Residential Builder license or M&A Contractor license with the roofing classification, or the license is not active through LARA.
• They offer to waive, rebate, or absorb your insurance deductible.
• They push you to sign before you read your declarations page and understand your wind/hail deductible.
• Their estimate does not spell out tear-off, decking, underlayment, ice-and-water shield, flashing, ventilation, and cleanup.
• They talk only about shingle brand or class, but not attic conditions, eaves, valleys, and penetrations.
• They will not provide current general-liability and workers'-compensation insurance information.
• They rely on verbal promises instead of a written scope and material list.
• They cannot point to a real local track record or recent references.

What is the smartest way to choose a roofer in Michigan?

Start with the legal check, then choose the clearest scope. Verify the active Michigan license through LARA. Confirm current general-liability and workers'-compensation insurance. Compare written scopes, not just prices. Make sure the proposal explains the water-management details that matter in this climate, especially ice-and-water protection, flashing, and ventilation. Then make sure you understand your deductible and policy terms before storm work begins.

If you want a faster way to compare your options, use 2026 market pricing as your baseline, review the full local pricing on the Michigan cost page, and pressure-test the scope with the calculator. The right roofer for your home is the one who can show the legal right to do the work, explain the system in plain English, and put every important detail in writing before the job starts.
