Allen Park particulars
Nineteen of every twenty Allen Park homes predate 1980: the Census ACS 2023 five-year estimates give 95.0 percent, with a median home value of $174,500. Ask any roofer what is under the top layer before work starts. Michigan's tear-off and re-cover rules are in our layers guide. Allen Park runs its own building-code enforcement according to the LARA Statewide Jurisdiction List (revised Oct 6, 2026), so the city issues roofing permits where one applies.
We did not read the city's roofing permit rule and the List does not say whether a re-roof needs one: the building department decides. For Wayne County, Michigan's Table R301.2(5) lists 20 psf of ground snow load (Northville is 25). NCEI's storm reports for Jul 2024 to Jun 2026 count 4 hail reports of 1 inch or larger on 3 days (largest 1.25 in), 29 wind reports of 50 knots or more on 13 days (largest 66 kt) and 2 tornado reports, and one storm can account for several of these reports. Lincoln Park is 1.9 miles away and Melvindale 2.0.
Roof replacement in Allen Park: what to know
Under the 2015 code's tear-off rule, a replacement removes existing layers of roof covering down to the roof deck. At the eaves the barrier extends at least 24 inches inside the exterior wall line, and we found no Michigan amendment that changes it. The 20 psf figure is the state table's value for Wayne County, measured as snow lying on the ground.
Nineteen in twenty homes here were built before 1980, so a tear-off may reveal several old applications, and the code bars covering a roof that already has two or more. The city's permit office was not read, so fees and inspections are open questions. Get the building department's answer first, and let the contract say who files.
Permits for roof replacement in Allen Park
Roofing is not on the state's exemption list, enforcement is local, and cities answer differently.
Many cities run their own building department, so start by asking the City of Allen Park building department who issues roofing permits.
When a replacement cannot wait for the calendar
- The old covering is off and the deck is open to rain or snow with no cover on it. Ask the company in writing what it will do tonight.
- Water is entering the house during the job.
- An aging roof with no leaks: compare written estimates and read your policy first.
What to gather before you ask for estimates
Try this first: ask the company how many layers it expects to find and what it does if the answer changes.
- Find your declarations page and note whether roof losses settle at actual cash value or replacement cost, and whether you have ordinance and law coverage.
- Get written estimates, as DIFS advises, and ask each company what it will do about tear-off to the deck, the ice barrier, underlayment, flashing and the permit.
- Check each license number on LARA before you sign.
What roof replacement costs
The estimate below is the Michigan-wide one, adjusted for Michigan wages and not for Allen Park in particular. The same table is on the roof replacement page. How we estimate costs. Prices as of Oct 19, 2026.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $6,225 to $15,400 per roof, tear-off included | Built from two national published ranges, adjusted by the Michigan roofer median wage ratio (1.07) plus a typical permit fee ($100). No Michigan roofing company price is shown, because none of the companies we looked at published a price we could count. |
| Estimated range per square, not a quote | $275 to $740 per square (100 square feet), installed | 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 helper wage, Michigan median | $20.07 an hour | 25th to 75th percentile $18.50 to $23.86. A wage, not a price. Medium confidence. |
| Residential re-roofing permit, Grand Rapids | $66 | FY2027 fee schedule. |
| Roof or re-roof permit, Sterling Heights | $78, plus $56 application | Building permit application, 2026-27. |
| Roof permit, East Lansing | $60 application, plus $140 residential | Unclear whether the $140 includes the $60. |
| Re-roofing permit, Kalamazoo | $52 | 2026 fee schedule; other fees may add to it. |
| Roofing permit, Midland | Valuation is squares times $300; table starts at $78 for the first $1,000 | Whether the roofing fee uses this table is our inference. |
How we estimate costs: the Estimated range row is a model, not a quote. It takes two published national ranges for this job (cost guides from third-party sites that we have not verified and do not cite) and multiplies them by Michigan's roofer median wage ratio to the US (1.07, BLS May 2025 data read through O*NET OnLine) and adds a typical permit fee ($100). 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 replacement
How many layers of shingles can a Michigan roof have?
Under the 2015 code, a re-cover is barred where the existing roof already has two or more applications of roof covering, so a second layer in total is the limit. A replacement includes tear-off to the deck. Re-cover is also barred over a water-soaked or deteriorated roof.
Does Michigan require an ice barrier on a new roof?
Michigan's table says yes, along the eaves: from the lowest edge to at least 24 inches inside the exterior wall line. Slopes of 8:12 or steeper also need at least 36 inches along the slope. We rate the distances medium confidence.
Do I need a permit to replace my roof in Michigan?
It depends on your city: Grand Rapids and Sterling Heights require one, and Portage requires none for shingles only. Ask the building department before you sign.
