Tyrone Township has published nothing that names roof work, so plan on a building permit for a reroof and ask first. The Township's permit packet (the "Zoning Building Permit" document on its Forms & Permits page) holds a one-page "Application for Tyrone Township Building Permit" and says the building permit fee is "Base fee" of $75.00 and $3.50 "per $1000 of cost"; the Township's fee ordinance (Section 145.001) sets "Base fee" $75.00, $10.00 on the first $1,000.00 of cost and $3.50 "Per $1,000.00 of cost or fraction thereof", with $30.00 for examination of plans and specifications, and has no roofing line; Section 145.007 says "The total permit fee is doubled if work is started before application for a permit is made", and Section 145.009 lets the Township Board change the fees by resolution. The packet says the zoning application "must be approved before a building permit will be issued" (zoning application "Under 999 sq ft $40.00 Over 1000 sq ft $130.00") and its checklist says "Permit is issued by the Building Inspector" and "Please call 48 hours before you need the inspection". The Township's contractor registration sheet says "Only registered licensed contractors can obtain permits" and "Homeowners can obtain a Homeowner Permit for a single-family dwelling in which he lives or is about to occupy for not less than one (1) year." The Township office is open Monday to Thursday, 9 a.m. to 4 p.m., and closed Friday, at 616-678-4779; its page lists the Building Inspector's office hours as "By appointment" at 616 437 7201.

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 Tyrone, Kent County, as its own building code enforcer. The Township's codified Section 146.001 adopts "the State (Building, Electrical, Plumbing & Mechanical) Codes prepared and promulgated by the State Construction Code Commission" together with "any amendments made hereafter to that Code by the State Construction Code Commission", and names no code edition; the Township's building permit packet carries a worksheet headed "2015 Michigan Residential Code" for the energy provisions of new single-family buildings.

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). Tyrone Township's codified building ordinances (Parts 131, 145, 146 and 147) and its permit pages and forms were read for a local rule and state nothing further on drip edge. About drip edge

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). Tyrone Township's codified building ordinances (Parts 131, 145, 146 and 147) and its permit pages and forms were read for a local rule and state nothing further on ice barrier.

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." Tyrone Township's codified building ordinances (Parts 131, 145, 146 and 147) and its permit pages and forms were read for a local rule and state nothing further on impact resistance.

Tyrone Township has published no size, cost or repair threshold for roof work, and no page, form or fee schedule that the Township publishes names roofing or reroofing. Its sheet "To All Contractors Working in Tyrone Township" says "Permit is required prior to commencement of work", and its building permit checklist says "You must have your permit before any construction begins"; neither names roof work either way. 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. Ask the Township office (616-678-4779) before starting a roof job.

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 own building instruments were read in full through the Municode compilation of Tyrone Township's general ordinances (codified through Ordinance No. 45[B], enacted January 21, 2020): Part 146 (State Codes), Part 145 (State Construction Code fee schedule), Part 147 (Miscellaneous fees) and Part 131 (Dangerous Buildings), with the compilation's listing of ordinances. None has a reroofing provision, and none amends anything in Section R908. The Township's permit pages and forms state no layer rule.

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). Tyrone Township's codified building ordinances (Parts 131, 145, 146 and 147) and its permit pages and forms were read for a local rule and state nothing further on roof sheathing.

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 Tyrone Township permit pages or in its fee ordinances changes this.
