Do you need a permit to replace a roof in Frankenmuth, MI?
Adopted code
City of Frankenmuth - Construction Codes Group
No, Frankenmuth, MI does not require a permit for like-for-like roof replacement (City of Frankenmuth - Construction Codes Group). In the City of Frankenmuth a reroof that only removes and replaces shingles needs no permit in the Construction Codes Group's own words: "If you are merely removing and replacing shingles, you do not need a permit. If the work involves replacing any portion of the structure or replacing the support structures or wood underneath you most likely need a permit. Call 989-652-9901." A tear-off that reaches the structure or the wood underneath most likely needs one. The permit rules were read before this answer was published: Michigan's list of work exempt from permit (Section R105.2 of the residential code, as Michigan amends it) names no roof work; Chapter 98 of the City Code designates the enforcing agency and adds no permit section or local amendment; the Group's building permit application (updated July 2026) lists New Building, Alteration, Demolition, Foundation Only, Relocation, Addition, Repair, Premanufacture, Special Inspection and Other as types of improvement, with no roofing type, and its fee schedule for "remodels/alterations" has no roofing line (up to $1,000, $85.00; $1,001 to $10,000, $85.00 base fee plus $7.00 per $1,000 of construction; $10,001 to $50,000, $155.00 base fee plus $6.00 per $1,000). In an area of special flood hazard, Section 8.80 of the City Code (Chapter 100) says "A Development Permit shall be obtained before construction or development begins within any area of special flood hazard", and the chapter defines "Development" as "any manmade change to improved or unimproved real estate"; it names no roof work, so ask the Group before a reroof on a flood-zone parcel. The Group's FAQ also says "Siding, exchange of same size doors & windows, landscaping, paving your drive, and an accessory building of 160 square feet or less" and, for the Historic Preservation District, "you should check for additional guidance"; its application says "Plans are not required for alterations & repair work determined by the building official to be of a minor nature", and the FAQ says "Once issued, the project must commence within 6 months of that date." The Group says "Please call 989-652-9901 to verify if permits and plans are needed". Its office, at 240 W Genesee St, Frankenmuth, MI 48734, is open Monday to Friday, 8:30AM to 5:00PM, and permits can be paid online through the Group's site, where credit card fees apply.

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 Construction Codes Group registers contractors itself. Its Contractor Registration Form carries a "Fee: $15.00", asks for the licensee's occupational license number, workers' compensation insurance carrier or exemption, federal employer identification number and Michigan employment security number, and says "TO BE PROVIDED: 1.) COPY OF STATE LICENSE 2.) COPY OF DRIVER'S LICENSE"; the building permit application lists a "Contractor Registration Fee" of $15.00.

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 Frankenmuth as its own building code enforcer. Section 8.15 of the City Code says "the Building, Electrical, Mechanical and Plumbing Officials of the City of Frankenmuth are hereby designated as the enforcing agency" and names no code edition. The Construction Codes Group's code list, revised 03/2025, says "CODES IN EFFECT (03/2024)" and lists the state construction codes as the 2015 MBC and the 2015 MRC with the Michigan Energy Code.
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 Frankenmuth's Title VIII building regulations (Chapters 97, 98 and 100) and Chapter 61 (Housing Regulations) of the City Code, and the Construction Codes Group's permit pages, forms and FAQs, 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 Frankenmuth's Title VIII building regulations (Chapters 97, 98 and 100) and Chapter 61 (Housing Regulations) of the City Code, and the Construction Codes Group's permit pages, forms and FAQs, 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 Frankenmuth's Title VIII building regulations (Chapters 97, 98 and 100) and Chapter 61 (Housing Regulations) of the City Code, and the Construction Codes Group's permit pages, forms and FAQs, were read for a local rule and state nothing further on impact resistance.
Repair permit threshold
The Construction Codes Group's FAQ, read October 12, 2026, answers "Do I need a permit to roof my house?" with "If you are merely removing and replacing shingles, you do not need a permit. If the work involves replacing any portion of the structure or replacing the support structures or wood underneath you most likely need a permit. Call 989-652-9901." The enacted text names no roof work either way: the state construction code act says "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" and "A building permit is not required for ordinary repairs of a building or structure." (MCL 125.1510), without defining ordinary repairs or capping them by size or cost. Michigan's list of work exempt from permit (Section R105.2 of the residential code, as Michigan amends it) names no roof work. The City Code's Chapter 98 (General Building Regulations) only designates the enforcing agency and the Group's permit application lists no roofing type, so the no-permit line is the Group's stated practice for a shingle replacement, and this record does not decide whether it is the Group's reading of the state relief. In an area of special flood hazard, Section 8.80 of the City Code (Chapter 100) says "A Development Permit shall be obtained before construction or development begins within any area of special flood hazard", and the chapter defines "Development" as "any manmade change to improved or unimproved real estate"; it names no roof work, so ask the Group before a reroof on a flood-zone parcel.
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 of Frankenmuth's own building instruments were read: Title VIII (Building Regulations) of the City Code, Chapters 97 (Wrecking and Demolition), 98 (General Building Regulations) and 100 (Flood Damage Prevention), and Chapter 61 (Housing Regulations), which adopts a property maintenance code. None has a reroofing provision, and none amends anything in Section R908. The Construction Codes Group's pages, forms and FAQs 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 Frankenmuth's Title VIII building regulations (Chapters 97, 98 and 100) and Chapter 61 (Housing Regulations) of the City Code, and the Construction Codes Group's permit pages, forms and FAQs, 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 Construction Codes Group's pages or forms changes this.
