Adopted code
City of Allegan - Building Department (Professional Code Inspections of Michigan, Dorr office)
Yes, a permit is required to replace a roof in Allegan, MI, issued by City of Allegan - Building Department (Professional Code Inspections of Michigan, Dorr office). The City of Allegan has published nothing that names roof work, and neither has Professional Code Inspections, the firm that runs its building department, so the state's general permit rule supplies the requirement and the city's referral is quoted: "Call the PCI office for questions relating to this." Under that rule, "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 city's Guide to Development says "Professional Code Inspections of Michigan handles all building permitting actions for the City of Allegan. All building permit applications and associated fees must be submitted to PCI of Michigan", and that applicants "will be contacted within 10 days of submittal." PCI's Dorr office is at 1575 142nd Street, Dorr, MI 49323, phone 616-877-2000, and the city's own Forms and Applications page links its Building Department to PCI's Dorr office forms page. PCI's BS&A Online page says building permit applications can be submitted online and that contractors "can use the system to request inspections for issued permits". No building fee schedule for the City of Allegan is posted on the city's or PCI's pages read for this record, so ask PCI for the current fee; the Guide says only "fees may apply". City Hall, which does not issue building permits, is at 231 Trowbridge Street, Allegan, MI 49010, phone 269-673-5511.

Registration details
- state_level: Michigan licenses residential maintenance and alteration contractors under the Occupational Code, and that licence "includes the following crafts and trades" among which it names roofing (MCL 339.2404(3)); "A person shall not engage in or attempt to engage in the practice of an occupation regulated under this act" without the licence (MCL 339.601(1)). MCL 339.2403 lists who may work without one, including a project whose "aggregate contract price for the labor, material, and any other items for the undertaking or project is less than $600.00". This record does not decide whether a given roofer falls inside an exemption.
- city_level: The application for a building permit that Professional Code Inspections uses for the City of Allegan asks for the contractor's "BUILDERS LICENSE NO.", federal employer ID number, workers' compensation insurance carrier and MESC employer number; the city and PCI publish no registration of their own.

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 City of Allegan as its own building code enforcer. The city's Guide to Development and the permit pages and forms of Professional Code Inspections, its building department, name no residential code edition; the city's codified ordinances are published on a code host that this record could not open, so they were not read, and the city has published no statement of which edition it enforces.
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 City of Allegan's Guide to Development and the building permit application and requirements sheet of Professional Code Inspections of Michigan, its building department, 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 City of Allegan's Guide to Development and the building permit application and requirements sheet of Professional Code Inspections of Michigan, its building department, 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 City of Allegan's Guide to Development and the building permit application and requirements sheet of Professional Code Inspections of Michigan, its building department, were read for a local rule and state nothing further on impact resistance.
Repair permit threshold
No size or cost threshold for roof work is published. The City of Allegan's Guide to Development, which names no roofing, says "Please note that not all projects will need a building permit." and "In addition, there are many types of projects that may be considered maintenance. Call the PCI office for questions relating to this." The Building Permit Requirements sheet of Professional Code Inspections, the city's building department, asks that "ALL BUILDING PERMIT APPLICATIONS" come with "A COMPLETED BUILDING PERMIT APPLICATION" and plans, and its Application for Building Permit lists new building, addition, alteration, demolition, relocation and sign among the project types, with no roof type, and asks for a "PROJECT VALUATION". Under state law, "A building permit is not required for ordinary repairs of a building or structure." (MCL 125.1510), without a definition of ordinary repairs, and the city has published nothing applying that relief to roof work. For a small patch, ask PCI at 616-877-2000 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 city's building ordinances were not read because its codified ordinances are published only on a code host that this record could not open, so this record states no layer classification. The city's Guide to Development and the permit pages and forms of Professional Code Inspections, its building department, state no layer rule.
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 City of Allegan's Guide to Development and the building permit application and requirements sheet of Professional Code Inspections of Michigan, its building department, 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 in the City of Allegan's Guide to Development or on the permit pages of Professional Code Inspections changes this.
