Ann Arbor particulars
The state's snow table lists Washtenaw County at 25 psf of ground snow, with Ann Arbor, Ypsilanti and Saline at 20. That is snow on the ground, not the load on a roof. Ann Arbor also has 15 local historic districts, where the city says work is reviewed by the Historic District Commission and by city staff, and building permit applications in a district get a staff review with a $35 fee on the fee schedule.
The city's page does not name roofs, so whether a re-roof triggers that review is something to ask before you sign. Building and Construction Services is at 301 E. Huron St, 734-794-6263, and applications go through STREAM. Housing in Ann Arbor is 64.3 percent pre-1980 with a median home value of $435,100, the highest in our first group of cities. For storms, Washtenaw County had 1 hail report of 1 inch or larger and 12 wind reports of 50 knots or more on 6 days (largest 61 kt) in Jul 2024 to Jun 2026, plus 1 tornado report.
Reports naming Ann Arbor itself give 7 wind and 1 tornado, a minimum. Roofer pay in the Ann Arbor metro has a median of $29.68 an hour (medium confidence, via O*NET): pay, not price. See Ypsilanti and Novi too.
Roof repair in Ann Arbor: what to know
Building and Construction Services at 301 E. Huron St takes applications through STREAM and answers at 734-794-6263. We found no roofing-specific page for the city, so whether a repair needs a permit is for that office to say. In a local historic district, the city says work is reviewed by the Historic District Commission and by city staff; the page does not name roofs, so ask whether your repair is caught.
Under state law, roofing jobs of $600 or more on a single project need a residential maintenance and alteration license, with an exemption for an owner on their own home. The Census puts 64.3 percent of Ann Arbor homes before 1980, with a median home value of $435,100, so the house under the repair may be newer than in most of our cities but is worth more.
Permits for roof repair in Ann Arbor
Michigan's own list of permit exemptions does not include roofing or roof repair, and enforcement is local.
Many cities run their own building department, so start by asking the City of Ann Arbor building department who issues roofing permits.
Which roof repairs cannot wait
- Water is coming through the ceiling now. See emergency roof repair for what to do first.
- A section of roof deck is exposed or sagging.
- A few missing shingles over a dry attic: photograph them and call your insurer.
- A loose flashing edge or a stain that has not grown after rain.
What you can check without going on the roof
Try this first: look up your address on the city's historic district map before you request a repair estimate.
- Look at the roof from the ground, with binoculars if you have them, for missing or curled shingles and gaps near chimneys and vents.
- Check ceilings and the attic from the hatch for stains and damp, and photograph them with the date.
- Stay off the roof, especially when it is wet, icy or covered in snow.
What roof repair costs
The estimate below is the Michigan-wide one, adjusted for Michigan wages and not for Ann Arbor in particular. The same table is on the roof repair page. How we estimate costs. Prices as of Oct 19, 2026.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $135 to $3,700 per repair, minor to moderate | Built from one national published range, adjusted by the Michigan roofer median wage ratio (1.07). No Michigan roofing company price is shown, because none of the companies we looked at published a price we could count. |
| Roofer wage, Michigan median | $28.62 an hour | 25th to 75th percentile $23.02 to $37.56. What Michigan roofers are paid (BLS May 2025, read through O*NET OnLine), not what a company charges you. Medium confidence. |
| Roofer wage, Detroit-Warren-Dearborn median | $30.48 an hour | 25th to 75th percentile $23.60 to $37.97. A wage, not a price. Medium confidence. |
| Residential re-roofing permit, Grand Rapids | $66 | FY2027 fee schedule; no repair fee is listed there that we can cite. |
| Re-roofing permit, Kalamazoo | $52 | 2026 fee schedule; other application fees may add to it. |
| Reroofing or residing permit, Flint, value under $5,000 | $140 | FY27 master fee schedule; the table is flattened, so confirm the split with the city. |
How we estimate costs: the Estimated range row is a model, not a quote. It takes one published national range for this job (a cost guide from a third-party site that we have not verified and do not cite) and multiplies it by Michigan's roofer median wage ratio to the US (1.07, BLS May 2025 data read through O*NET OnLine). The wage and permit rows in the table are what roofing workers are paid and what a city's own schedule charges, and neither is a price. We have not collected quotes, and we found no Michigan roofing company that publishes a price we could count. Full method.
Questions about roof repair
Can you repair just part of a roof?
Yes, and DIFS says that after hail or wind a homeowners policy covers only the damaged portion of the roof. The base under the repair matters; see the section above.
Is it cheaper to repair or replace a roof?
A repair is the smaller job: our estimate is $135 to $3,700 for a repair and $6,225 to $15,400 for a replacement. Those ranges are modeled estimates, not collected Michigan prices, so they cannot tell you which costs less over the years. The better question is what the deck and underlayment look like under the damage.
What is the average price of a roof repair in Michigan?
Our estimate is $135 to $3,700 per repair, minor to moderate. It comes from one published national range adjusted for what Michigan roofers are paid (the median is $28.62 an hour, BLS May 2025, medium confidence), so use it to judge a written quote, not as one. We found no Michigan roofing company that publishes a repair price.
