Adopted code
Township of Hanover (Jackson County) - Building Department
Yes, a permit is required to replace a roof in Township of Hanover, MI, issued by Township of Hanover (Jackson County) - Building Department. A reroof in Hanover Township goes through the Building Department's own roofing permit. The Building Department page lists "Roof/Re-Roof Permit" with its own "BUILDING PERMIT APPLICATION-ROOF", and the application is headed "ROOFING PERMIT APPLICATION FEE: $170" (revised 08/2024); it asks for the contractor's business name, license numbers, insurance carrier and policy number, and the estimated square footage and construction value. The department states no exemption for roof work. The state's general permit rule also applies: "before construction of a building or structure, the owner, or the owner's builder, architect, engineer, or agent, shall submit an application in writing to the appropriate enforcing agency for a building permit." The same section says "A building permit is not required for ordinary repairs of a building or structure," without defining ordinary repairs, and the department has published nothing applying that relief to roof work. The Building Department page says "Permits will be issued within 72 hours of receiving completed application and fees." and "BUILDING PERMITS WILL ONLY BE ISSUED ON MONDAYS, WEDNESDAYS, AND THURSDAYS." It adds "As of April 1, 2024 Inspection Fees for all Permits are now: $85 per Inspection ($70 Inspection fee, $15 Administrative Fee)", and "A Site Inspection is required for any new structures, additions, or any other project that covers ground area." The roof application lists the Building Inspector at (517) 513-7330, and its homeowner's affidavit says work "will not be enclosed, covered up, or put into use until it has been inspected and approved by the Building Inspector." The office, at 311 Farview Street, Horton, MI 49246, is "Open Monday-Thursday, 8 AM-12 PM and 1 PM-4 PM. Closed Friday."; its number is 517-563-2791.

Adopted code
2015 Michigan Residential Code. This is state law and it is the same in every Michigan city, village, township and county: the state construction code act says "This act and the code apply throughout the state," and the Michigan Residential Code rule adopts "the international residential code, 2015 edition" with the state amendments in R 408.30500 to R 408.30547g. A 2021 edition was filed with the secretary of state in 2025 but has not taken effect. On July 7, 2025 the Michigan Court of Claims entered a stipulated order in Home Builders Assoc et al. v LARA et al., and the Michigan Department of Licensing and Regulatory Affairs (LARA) says that while that order remains in place "the 2015 versions of the IRC and residential provisions of the IECC standards currently adopted, in part, by each rule set will remain valid and in effect." LARA's Statewide Jurisdiction List names the Township of Hanover in Jackson County as its own building code enforcer. Locally, the township's permit applications say in the homeowner's affidavit that work will be installed "in accordance with the building code adopted by the Township", and the township's Ordinances page posts a Zoning Ordinance and a Public Property Safety Policy and no building code ordinance. None of these names an edition year or an older residential code edition, so this record states the 2015 Michigan Residential Code for the reasons above.
Drip edge
Required — Required on asphalt shingle roofs by state law. Michigan makes no amendment to the drip edge rule of the 2015 International Residential Code, Section R905.2.8.5, which applies as published: "A drip edge shall be provided at eaves and rake edges of shingle roofs." Segments overlap by at least 2 inches, the drip edge extends at least 1/4 inch below the roof sheathing and at least 2 inches back onto the deck, it is fastened at no more than 12 inches on center, and underlayment goes over it at the eaves and under it at the rakes. A reroof is held to the same rule, because "Materials and methods of application used for re-covering or replacing an existing roof covering shall comply with the requirements of Chapter 9" (R908.1). The Hanover Township Building Department page, roofing permit application and short building permit application were read for a local rule and state nothing further on drip edge.
About drip edgeIce & water shield
Required — Required everywhere in Michigan by state law. Michigan fills in the climatic design table of the 2015 code once for the whole state (Rule 516, Table R301.2(1)), and its ice barrier underlayment column reads Yes. The state footnote calls for Yes "for areas where the average daily temperature in January is 25 degrees Fahrenheit" or less, or where ice damming has caused damage. The base code then requires an ice barrier "for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes," running "from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building" (R905.1.2). Detached accessory structures without conditioned floor area are exempt. On a tear-off, an existing ice barrier that is adhered to the deck may stay and be covered with an additional layer (R908.3, Exception). The Hanover Township Building Department page, roofing permit application and short building permit application were read for a local rule and state nothing further on ice barrier.
About ice & water barrierImpact-resistant roofing
Not required — No impact-resistance requirement under state law. The 2015 Michigan Residential Code was searched in full and has no hail or impact rating rule for roof coverings: the words hail, impact and UL 2218 do not appear in it, and none of them appears in the roof assemblies chapter of the base 2015 International Residential Code either. Michigan applies one code statewide ("This act and the code apply throughout the state."), and the act gives the power to amend it to the state director, who adopts the model codes "with amendments, additions, or deletions as the director determines appropriate." The Hanover Township Building Department page, roofing permit application and short building permit application were read for a local rule and state nothing further on impact resistance.
Repair permit threshold
Hanover Township's Building Department has its own roofing permit. Its Building Department page lists "Roof/Re-Roof Permit" with a "BUILDING PERMIT APPLICATION-ROOF" as a separate application from its short application for "Add/Alter/Repair/Accessory Structure Building Project", and the roof application is headed "ROOFING PERMIT APPLICATION FEE: $170" (revised 08/2024). It states no size, square or dollar point below which roof work needs no permit; the application asks for the structure "WHERE ROOFING IS BEING INSTALLED" ("House", "Shed", "Garage, Attached", "Garage, Detached", "New Construction" or other), the estimated square footage and the estimated construction value. The state part: Michigan's construction code act says "A building permit is not required for ordinary repairs of a building or structure" and does not define ordinary repairs. For a small roof repair, call the Building Department at 517-563-2791 before starting.
Roof layer limit / recover
Two layers at most, under state law. Michigan builds one- and two-family homes to the 2015 Michigan Residential Code, which adopts the 2015 International Residential Code and makes no amendment to its reroofing section, Section R908; the Michigan rule set was searched in full and R908 does not appear in it. The base section therefore applies as the International Code Council publishes it. Section R908.3.1.1 lists the conditions under which a new roof may not be laid over an existing one, and the third is "Where the existing roof has two or more applications of any type of roof covering." One existing layer may be covered once; a roof that already carries two layers is torn off to the deck. The same section also bars covering a roof that is water soaked or too deteriorated to serve as a base, and covering "slate, clay, cement or asbestos-cement tile." Locally, the township's Ordinances page posts a Zoning Ordinance and a Public Property Safety Policy and no building ordinance, and the Building Department page, the roofing permit application and the short building permit application state no layer rule; no local building ordinance was found to read for Section R908.
Deck & sheathing requirements
State law, from the base code. Michigan makes no amendment to the roof sheathing section of the 2015 International Residential Code, Section R803, which does not appear in the Michigan rule set, so it applies as published. Lumber roof sheathing follows Table R803.1: over rafters or beams 24 inches apart it must be at least 5/8 inch net thick. Wood structural panels must be identified "for grade, bond classification and performance category by a grade mark or certificate of inspection issued by an approved agency," and their spans may not exceed "the values set forth in Table R503.2.1.1(1), or APA E30." For a shingle roof the base code adds that "Asphalt shingles shall be fastened to solidly sheathed decks" (R905.2.1), and on any reroof "The structural roof components shall be capable of supporting the roof covering system" (R908.2). The Hanover Township Building Department page, roofing permit application and short building permit application were read for a local rule and state nothing further on roof sheathing.
Sales & use tax
6%, statewide, with no local add-on. This is state law: the General Sales Tax Act sets the tax "equal to 6% of the gross proceeds of the business," the Use Tax Act sets "a total combined rate equal to 6%," and the Michigan Department of Treasury says "Michigan does not allow city or local units to impose sales tax." On a roofing job the roofer is the taxpayer on materials, because the Use Tax Act counts as a consumer "A person acquiring tangible personal property if engaged in the business of constructing, altering, repairing, or improving the real estate of others." Nothing on the Hanover Township Building Department page or in its roofing permit application changes this.
