Roof Replacement Permit in Ann Arbor, Michigan
It depends
Sometimes, depending on the project
Before reroofing or recovering an existing flat roof. Not needed to replace a sloped asphalt shingle or metal roof.
By Mario Bailey, verified against official sources
Quick answer
Ann Arbor draws the roofing permit line by roof type rather than by area or cost. The city's expedited residential permits handout states that sloped asphalt shingled and metal roofs do not require a permit, while reroofing or recovering an existing flat roof does and is one of the work types eligible for expedited plan review. A flat roof submittal must show the location of work plus the membrane specification, the parapet condition where applicable, the slope and direction of drainage, and the replacement insulation R value. Structural changes to a roof, as opposed to a like for like covering replacement, still fall under the ordinary building permit rules.

How to apply in Ann Arbor
A residential reroof permit application is lighter than for structural work: you state whether the scope is a full tear-off (roof replacement) or an overlay (roof recover), describe the covering material and its manufacturer instructions, and note the condition of the existing deck, since those facts determine which code path applies.
What most roof replacement permit applications include:
- State on the application whether the job is a roof replacement, which strips all existing layers down to the bare deck, or a roof recover, which leaves the old covering in place under specific conditions, since the two scopes are governed differently (IRC R908.3).
- A recover is only an option where the new covering follows the roof covering manufacturer's approved instructions or is a self-supporting system, such as standing-seam metal, that does not rely on the existing roof for support (IRC R908.3.1).
- Full tear-off must be scoped on the application instead of a recover when the existing roof is water soaked or deteriorated, is slate, clay, cement, or asbestos-cement tile, or already carries two or more layers of roof covering (IRC R908.3.1.1).
- The materials and installation methods described on the application must comply with the reroofing requirements of the roof-assemblies chapter (IRC R908.1).
- If the scope reuses existing slate, clay, or cement tile, damaged or broken pieces cannot be listed for reinstallation, and any rusted or deteriorated flashings, edgings, outlets, or vents uncovered during tear-off must be scoped for replacement (IRC R908.5).

Inspections and closing out your permit
Most residential reroofs get two to three field inspections keyed to the scope of work: a deck or nailing check when sheathing is exposed or replaced, a final on the completed covering and flashings, and in some high-wind regions a dedicated check of mitigation measures added during tear-off.
- Where the covering is fully removed and the sheathing is exposed, replaced, or added, inspectors check the deck and its nailing before any new roofing goes down, since the structural framework must be able to carry the new covering's loads (IRC R908.2).
- An overlay is only approved where it meets one of the code's listed recover conditions, such as installation in accordance with the covering manufacturer's approved instructions (IRC R908.3.1).
- Flashings disturbed or replaced during the job are checked against the approved manufacturer's installation instructions, and metal flashing that will receive bituminous material must be primed before installation (IRC R908.6).
- A final inspection confirms the completed roof covering and its fasteners were installed as required for that material and per manufacturer instructions before the permit is closed (IRC R905).
- In some regions with strengthened wind provisions, reroofing an older single-family home also triggers inspection of supplemental deck-nailing and a secondary water barrier added during tear-off, on top of the base reroofing requirements (Florida Building Code, Residential R908.7 Mitigation).
- Reinstalled existing slate, clay, or cement tile is checked against reuse limits at inspection, and any rusted, damaged, or deteriorated flashings, edgings, outlets, or vents found during tear-off must be replaced rather than reinstalled (IRC R908.5).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Ann Arbor permit portal or by phone at 734.794.6263 ext. 0.

- Where do you apply for a roof replacement permit in Ann Arbor?
- You can apply through the Ann Arbor permit portal or contact the City of Ann Arbor Building, Rental and Inspection Services (Construction and Building), with zoning review by Planning and Development Services directly. The links are listed on this page.
- Can a homeowner pull a roof replacement permit themselves in Ann Arbor?
- Under Michigan law (MCL 339.2403(b), (c); MCL 339.2401(a)(iii), (b)(ii)(A); MCL 339.5737(3)(g); MCL 339.6107(2)(d); MCL 339.5819): Yes. A Michigan homeowner may pull the building permit and do the work on their own home without a residential builder license, because the licensing article both defines the trade to exclude them and exempts them outright. MCL 339.2401(a)(iii) says a residential builder is a person that erects a residential structure except for the person's own use and occupancy on the person's property, and MCL 339.2403(b) exempts an owner of property with reference to a structure on the property for the owner's own use and occupancy. Own use and occupancy is the condition, so the exemption does not cover building to sell, and MCL 339.2403(c) limits owners of rental property to maintenance and alteration of that property. The statute sets no cap on how many times a homeowner may use the exemption; the only frequency rule in the article catches purchase, substantial rehabilitation, and resale of the same structure more than twice in 1 calendar year, and MCL 339.2401(b)(ii)(A) exempts work for the person's own use and occupancy from even that. Homeowners can also pull their own trade permits: electrical work in a single family home and accompanying outbuildings owned and occupied or to be occupied by the person doing the work (MCL 339.5737(3)(g)), their own plumbing, building sewer, or private sewer in their single-family dwelling if a permit is secured (MCL 339.6107(2)(d)), and a heating or refrigerating system if the owner affirms in the permit application that they are or will become the owner and occupant (MCL 339.5819). Confirm how Ann Arbor applies this before you apply.
