Charter Township of Caledonia - Building and Code Enforcement
Yes, a permit is required to replace a roof in Charter Township of Caledonia, MI, issued by Charter Township of Caledonia - Building and Code Enforcement. The township's published permit material says nothing specific about roof work: the Building & Code Enforcement page, the Documents & Permits page, the building permit application, the zoning permit application and Chapter 10 of the Code of Ordinances name no roofing line and no reroof exemption. With the township silent on reroofs, the state's general permit rule 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 township has published nothing applying that relief to roof work. The Building & Code Enforcement page says "The Building Department reviews permit applications for code compliance, issues permits for residential, commercial, and industrial projects, conducts inspections throughout all phases of construction", and for electrical, plumbing and mechanical work it lists the township at "(989) 743-5300 Ext. 230". The township's building permit application is the state-format form "APPLICATION FOR BUILDING PERMIT AND PLAN EXAMINATION", and it says "Checks shall be made payable to: Caledonia Township". The township posts no building permit fee schedule. Its zoning permit application says "Complete application must be RECEIVED BY THE ZONING ADMINISTRATOR at least 10 days prior to the issuance of the zoning permit" and lists the "Zoning Permit Application" fee at "$ 50.00". The Building & Code Enforcement page sends well, septic and soil erosion questions to the Shiawassee County Health Department, at (989) 743-2390.

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 Charter Township of Caledonia, in Shiawassee County, as its own building code enforcer; it is a different unit from the Township of Caledonia in Kent County. Section 10-1 of the township's Code of Ordinances designates "the building official of the township" as the enforcing agency under the state act and names no code edition, and the township's Ordinance No. 2024-01 adopts "the NFPA Fire Code, 2021 edition", a fire code rather than a dwelling code. The township's Building & Code Enforcement page and its building permit application name no residential code edition.
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). Chapter 10 of the township's Code of Ordinances (Buildings and Building Regulations) and the township's Building & Code Enforcement page, building permit application and zoning 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). Chapter 10 of the township's Code of Ordinances (Buildings and Building Regulations) and the township's Building & Code Enforcement page, building permit application and zoning 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." Chapter 10 of the township's Code of Ordinances (Buildings and Building Regulations) and the township's Building & Code Enforcement page, building permit application and zoning permit application were read for a local rule and state nothing further on impact resistance.
Repair permit threshold
Caledonia Charter Township has published nothing that applies a permit or an exemption to roof work: its Building & Code Enforcement page, its Documents & Permits page, its Application for Building Permit and Plan Examination, its Application for Zoning Permit and its Code of Ordinances (Chapter 10, Buildings and Building Regulations) name no roofing line, no reroof exemption and no size or dollar point below which a repair needs no permit, and the township posts no building permit fee schedule; the Permit Fee Schedule on its Documents & Permits page is a zoning fee and escrow memorandum. 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. For any roof work, large or small, call the township office at 989-743-5300, the number the township's home page gives, 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 Code of Ordinances (codified through Ordinance No. 20030505C) was read for its building chapter: Chapter 10, Buildings and Building Regulations, designates the enforcing agency, sets permit fees by board resolution and creates the construction board of appeals, has no reroofing provision and amends nothing in Section R908. The other instruments listed on the township's Ordinances page, the Zoning Ordinance (amended October 1, 2015), the Solar Ordinance (adopted January 23, 2023), Ordinance No. 2024-01 (Fire Code) and the Sign Ordinance (a scan of Chapter 24 of the same Code of Ordinances), were searched and have no reroofing provision either. The Building & Code Enforcement page and the building permit application 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). Chapter 10 of the township's Code of Ordinances (Buildings and Building Regulations) and the township's Building & Code Enforcement page, building permit application and zoning 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 Caledonia Charter Township Building & Code Enforcement page changes this.
