Michigan pairs a low $600 license threshold with a two-track LARA contractor system and one of the strictest ice-barrier codes in the country. Pick your region below for 2026 pricing, then read the rules that actually matter here: the LARA Residential Builder vs. M&A Trade Group Code R licenses, the MRC R905.1.2 ice-barrier rule, the MCL 500.4503 insurance-fraud felonies, the 2015 Michigan Residential Code, and the MBPIA FAIR Plan.
Michigan is one of the few states that licenses roofers, but it does it in an unusual way: there are two different state licenses that legally let a contractor re-roof a home, and they are not interchangeable. Any home-improvement or roofing job worth more than $600 in combined labor and materials — one of the lowest, near-lowest license thresholds in the nation — requires the contractor to hold one of them, issued by the Michigan Department of Licensing and Regulatory Affairs (LARA). Both require 60-hour approved pre-licensure education, a passing PSI exam score, and a physical MI address on file — out-of-state storm chasers cannot legally hold either one.
Whichever license your contractor holds, Michigan law requires the 7-digit LARA license number to appear in three places before you ever pay a deposit: on the contractor’s wallet card, printed on the contract, and on the mandatory 3-day cancel notice attached to any contract you sign at your residence. A roofer who cannot show a current wallet card with a 7-digit number, or who leaves the license number off the contract, is operating outside the law — and you have a 3-day cancel right at the residence to walk away. Both license types also require a physical MI address on file with LARA.
Verify any Michigan license number at the LARA license search at michigan.gov/lara before signing.
Under MCL 339.601, performing residential building or roofing work over the $600 threshold without the required LARA license is a Misdemeanor. A first offense carries a fine of $5K-$25K; a repeat offense raises exposure to $50K and up to 2 years of imprisonment. Just as important for homeowners: an unlicensed contractor cannot sue you to collect on the contract or enforce a lien, and may have to refund money already paid.
After a storm, the biggest legal danger in Michigan is not a missing permit — it is a roofer who offers to “handle the insurance” by padding the scope, inventing damage, or eating your deductible. Michigan treats insurance fraud as a serious felony, and the homeowner who goes along with it can be charged as a co-conspirator. The governing statutes are MCL 500.4503 and MCL 500.4511 of the Insurance Code.
Under MCL 500.4503, knowingly presenting a false or fraudulent property-insurance claim — or helping prepare one — is a Felony. Under MCL 500.4511, the penalty is up to 4 years in prison and a $50K fine for a fraudulent claim. Conspiracy to commit insurance fraud raises that to 10 years and $50K, and for a licensed contractor it triggers mandatory license loss. A “free roof” or “we will waive your deductible” pitch is the front end of exactly this crime.

On the civil side, the Michigan Consumer Protection Act (MCPA) gives homeowners a private right of action against deceptive roofing practices. Under MCL 445.911, a homeowner harmed by an unfair or deceptive act — a misrepresented scope, a bait-and-switch on materials, or a phantom warranty — can recover the greater of $250 or actual damages, plus reasonable attorney fees. That attorney-fee provision is what makes a small roofing dispute worth a lawyer’s time and keeps reputable Michigan contractors documenting their work.
The MCPA lets a court award the homeowner the greater of $250 or actual damages for a deceptive act, and — critically — it shifts attorney fees onto the offending contractor. That fee-shift converts an otherwise too-small claim into one a lawyer will take on contingency, which is precisely why a Michigan roofer who pads a scope or misstates the license is exposed well beyond the dollar value of the job itself.

Unlike states that let each city adopt its own code, Michigan enforces a single mandatory statewide building code through LARA’s Bureau of Construction Codes. For one- and two-family homes, that is the 2015 Michigan Residential Code (2015 MRC) — and as of 2026 the residential code is still the 2015 MRC, even though the commercial side moved to the 2021 MBC in May 2025. Knowing which edition applies matters, because the 2015 MRC carries Michigan’s defining ice-barrier requirement.
The same residential code applies in Detroit, Grand Rapids, Traverse City, and the most remote township in the Upper Peninsula — there is no patchwork of local roof codes to research. As of 2026, residential re-roofs follow the 2015 MRC; commercial buildings follow the 2021 MBC, which took effect in May 2025. A contractor who claims a different residential edition applies to your house is either mistaken or improvising.
This is the single most important roofing line in the Michigan code, and the one out-of-state crews get wrong. Because nearly the entire state is an ice-dam zone, MRC R905.1.2 requires a self-adhering ASTM D1970 ice-barrier membrane at the eaves — and it must extend from the eave to a point at least 24 inches past the interior warm-wall line of the exterior wall. On a low-slope, deep-overhang Michigan home that can mean three or even four feet of membrane up the deck, far more than a single starter course.
Under MRC R905.1.2, in areas where there has been a history of ice forming along the eaves, an ice barrier of ASTM D1970 self-adhering polymer-modified bitumen sheet (or two layers of underlayment cemented together) shall be applied from the lowest edge of the roof to a point at least 24 inches inside the exterior wall line of the building — that is, 24 inches past the interior warm-wall line. Because virtually all of Michigan qualifies, this membrane is effectively mandatory statewide. Expect it to add a $500-$1,200 material premium over a basic synthetic underlayment.
How a compliant Michigan ice-barrier install goes:
Although Michigan’s building code is statewide, permit fees and the office that issues them are local. The two largest metros run re-roof permits through separate systems with very different fee structures — knowing the number keeps your contractor honest about what the city actually charges.
The Upper Peninsula (UP) is a different roofing climate from the rest of Michigan, and pricing reflects it. Lake-effect snow off Lake Superior buries the western UP under 140-200+ inches a year, producing ground-snow loads of 60-100+ psf — loads that quietly overwhelm decks and rafters sized for downstate. Asphalt shingles that last 25 years in Detroit are often spent in 10-14 yrs up north, which is why standing seam metal dominates serious UP re-roofs.
At 60-100+ psf ground-snow load, the structure under the roof matters as much as the covering. A compliant UP re-roof frequently calls for sister-rafter reinforcement or a re-deck to 7/16" OSB minimum to carry the load, and the covering trends to standing seam metal that sheds snow and outlasts asphalt. Budget for the structure, not just the shingles.
What a serious UP re-roof includes: a structural check for sister-rafter reinforcement, a re-deck to 7/16" OSB where sheathing is undersized or rotted, standing seam metal as the default covering, and full R905.1.2 ice-barrier coverage at every eave and valley. Skip the structure and the snow finds the weakness first.
Snow load is the dominant cost driver across Michigan, and it climbs sharply from the southeast corner to the Lake Superior shore. These ranges show why a Traverse City or UP roof is engineered for ice and load while a Detroit roof is detailed mainly for the eave ice barrier.
Average seasonal snowfall varies enormously across the state — the spread is what drives ice-barrier coverage, ventilation, and structural decisions region by region.
The through-line: every region of Michigan qualifies as an ice-dam zone under R905.1.2, so the ASTM D1970 ice barrier is in play statewide. What changes north and west is the structural load — which is where sister-rafter work, 7/16" OSB re-decking, and standing seam metal start showing up on quotes.
Michigan’s long roof-aging climate collides with how insurers pay claims. If your policy settles on an Actual Cash Value (ACV) basis rather than replacement cost, the carrier depreciates the roof for age before paying — and an aging asphalt roof depreciates fast.
Consider a $300K home with a 15-yr ACV asphalt roof. A full replacement might cost $14,000, but after 15 years of depreciation on a 25-year shingle the carrier may value the roof at little more than $6K — leaving the homeowner to cover the gap out of pocket. Confirm whether your policy is ACV or replacement-cost before a storm, because in Michigan’s climate the depreciation clock runs faster than most homeowners expect.
If a standard carrier non-renews or declines your Michigan home — for age, prior claims, or roof condition — the state has a safety net. The Michigan Basic Property Insurance Association (MBPIA) is the FAIR Plan and insurer of last resort, providing basic property coverage so a hard-to-insure home does not go completely uninsured.
The MBPIA writes HO-2 and HO-3 style coverage on occupied, code-compliant homes that cannot find a policy in the standard market. A new roof that meets the 2015 MRC — including the R905.1.2 ice barrier — properly documented, is one of the fastest ways to qualify for the plan and, later, to move back into the standard market.

All-in full asphalt-shingle replacement pricing for a typical single-family home, expressed per finished square foot of living area. Across the four regions, a 2,000 sq ft re-roof spans roughly $8,400 in West Michigan to $16,400 in the Upper Peninsula. Standing seam metal, structural reinforcement, and the R905.1.2 ice barrier run higher.
| Region | Major Metros | Cost / Sq Ft | Key Cost Driver |
|---|---|---|---|
| Detroit / SE | Detroit, Ann Arbor, Warren | $4.40 – $7.30 | BSEED $215 permit, older urban decks |
| West MI | Grand Rapids, Kalamazoo, Holland | $4.20 – $7.00 | Lake-effect snow, $130-$195 permits |
| Northern Lower | Traverse City, Petoskey, Gaylord | $4.60 – $7.70 | Heavy snow load, resort-market labor |
| Upper Peninsula | Marquette, Sault Ste. Marie | $4.80 – $8.20 | 140-200+ in snow, metal + sister-rafter |
Drill into a specific metro for localized labor rates, permit notes, and city-level cost data:
A typical 2,000 sq ft Michigan home runs roughly $8,400 to $16,400 for a full asphalt-shingle replacement in 2026. The Upper Peninsula prices highest because 140-200+ inches of annual snow and 60-100+ psf loads force structural upgrades and standing seam metal, while West Michigan around Grand Rapids is the most affordable major region.

Yes, on jobs over $600. LARA requires either an unrestricted Residential Builder license (PSI exam, $117, series #2101) or a Maintenance & Alteration license with M&A Trade Group Code R for roofing (PSI exam, $114, series #2102). Both need 60-hour pre-licensure education and a physical MI address. The 7-digit LARA number must appear on the wallet card, the contract, and the 3-day cancel notice. Working unlicensed violates MCL 339.601 — a Misdemeanor with a $5K-$25K fine first offense and up to $50K + 2 years for repeats.
Under MRC R905.1.2, the ice barrier must be a self-adhering ASTM D1970 membrane and must extend from the eave to a point at least 24 inches past the interior wall line of the exterior wall. Because nearly all of Michigan is an ice-dam zone, this membrane is effectively mandatory statewide and typically adds a $500-$1,200 material premium over basic underlayment. The residential code is the 2015 MRC as of 2026; commercial buildings moved to the 2021 MBC in May 2025.
Yes. Under MCL 500.4503 and MCL 500.4511, knowingly presenting a false or inflated property-insurance claim is a Felony punishable by up to 4 years and a $50K fine. Conspiracy with a contractor raises exposure to 10 years and $50K plus mandatory license loss. A homeowner can also recover under the Michigan Consumer Protection Act, MCPA MCL 445.911, for the greater of $250 or actual damages, plus attorney fees. A “free roof” or deductible-waiver pitch is the front end of this crime — report it to michigan.gov/difs.
