Blendon Township - Building Permits (Professional Code Inspections)
Yes, a permit is required to replace a roof in Township of Blendon, MI, issued by Blendon Township - Building Permits (Professional Code Inspections). Blendon Township's Forms & Ordinances page, read October 11, 2026, links a Building Permit application and separate Electrical, Mechanical and Plumbing permit applications, and its Planning & Zoning page lists its Zoning Administrator, whose contact details point to Professional Code Inspections. Neither page mentions roofing or reroofing, and no fee schedule is posted, so ask Professional Code Inspections for the current fee. The firm's Jenison office, at 1913 Baldwin Street, Jenison, lists Blendon Township among the municipalities it serves and posts a Blendon Township permit folder. That folder's sheet says "THE FOLLOWING INFORMATION IS REQUIRED TO BE SUBMITTED WITH ALL BUILDING PERMIT APPLICATIONS" and lists a completed application, three sets of plans for building projects, a site diagram, the legal description, and septic or well and driveway and soil erosion permits where they apply. The application asks for the project description and valuation, the contractor's builders licence number and its federal employer ID, workers compensation and MESC employer number or the reason for exemption. The firm accepts building permit applications online through its BS&A Online portal for the Jenison office, which also schedules inspections, and says only building permit applications can be submitted there; the other permit types are processed by its traditional methods. The township office is open Monday to Thursday, 9:00 AM to 5:00 PM, at (616) 875-7707. Neither the township nor the firm states anything on whether a reroof needs a permit, so call the firm at (616) 667-8803 before starting.

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: Blendon Township's Planning & Zoning page and Forms & Ordinances page, the Ordinances posted there and its Building Permit forms name no township contractor registration. The permit application asks for the contractor's state builders licence number and workers compensation and employer details. This record does not decide whether a given roofer falls inside a state exemption.

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 Blendon as its own building code enforcer. Township Ordinance No. 94-2012 designates "the Building Inspector/Zoning Administrator of the Township of Blendon" as the enforcing agency under the state construction code act and provides that Appendix G of the Michigan Building Code is enforced, and it names no residential code edition. The township's zoning ordinance refers to "the adopted Township Building Code" and to the "Blendon Township Building Code" without naming an edition, and the township's Forms & Ordinances page posts no building code ordinance. Professional Code Inspections' sheet for Blendon Township mentions a 2015 energy code and no residential code edition. 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). Blendon Township's Ordinance No. 94-2012, its zoning ordinance and its posted Building Permit forms were read for a local rule on drip edge and state nothing further on it.
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). Blendon Township's Ordinance No. 94-2012, its zoning ordinance and its posted Building Permit forms were read for a local rule on ice barrier and state nothing further on it.
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." Blendon Township's Ordinance No. 94-2012, its zoning ordinance and its posted Building Permit forms were read for a local rule on impact resistance and state nothing further on it.
Repair permit threshold
No size or cost threshold is published. Blendon Township's Planning & Zoning page, its Forms & Ordinances page and the Building Permit application it links name no roofing, reroofing or re-shingling, and the township posts no building permit fee schedule. Professional Code Inspections' sheet for Blendon Township says only that "THE FOLLOWING INFORMATION IS REQUIRED TO BE SUBMITTED WITH ALL BUILDING PERMIT APPLICATIONS." The township has published nothing on reroofs. 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.
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 building-related ordinance posted on its Forms & Ordinances page, Ordinance No. 94-2012, was read in full: it designates the enforcing agency and flood hazard areas and has no reroofing provision. The township's zoning ordinance, amended through February 2025, was searched and its roof provisions concern commercial building design, roof signs and accessory buildings, with no reroofing or layer rule. The zoning ordinance refers to a "Township Building Code" that the township does not post, so that text was not read and this record does not classify the township's own text.
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). Blendon Township's Ordinance No. 94-2012, its zoning ordinance and its posted Building Permit forms were read for a local rule on roof sheathing and state nothing further on it.
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 Blendon Township pages or the Professional Code Inspections pages changes this.
