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: Mayfield Township posts a Contractor Registration form that asks for the contractor's licence type (building, plumbing, mechanical or electrical), licence number and expiration date, and says "Please enclose a copy of Contractor License and Driver's License with this application." The form's registration fee is blank and the pages read do not say whether the township requires it before a building permit is issued.
Permit process note
Mayfield Township's Building & Zoning Department publishes nothing specific on reroofs. Its page says "In most cases, a Zoning Permit must be obtained from the Planning & Zoning Department prior to the issuance of a Building Permit." and "Please provide 24-hour notice for an inspection." It lists Building Department hours of Monday, Wednesday & Friday 9:00 a.m. - 4:00 p.m., and a 24-hour recorded inspection request line at (810) 664-2158; "Call the Township Offices at (810) 664-0821 to speak directly with Building Department personnel during the Department's regular hours." The Residential Building Permit Fees list is headed "Effective July 7, 2009" and prices new homes, additions, decks, pools, demolition and a "HOME REMODELING" line, with no roofing line, so confirm the current fee with the department. The Building Permit Information sheet says "Permits are available at the Township Hall during regular business hours".
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 Mayfield as its own building code enforcer. The township's Building Permit Application has the property owner certify that the work "shall be installed in accordance with the State Code". The township's pages and forms name no residential code edition, and no township building ordinance was found on its website (its Forms & Publications page lists a zoning ordinance and a master plan), so none was read for this record.
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 Mayfield Township Building & Zoning Department page, building permit application, permit information sheet and residential fee list were read for a local rule and were read for a local rule and state nothing further on drip edge.

Ice & 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 Mayfield Township Building & Zoning Department page, building permit application, permit information sheet and residential fee list were read for a local rule and were read for a local rule and state nothing further on ice barrier.
About ice & water barrier
Impact-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 Mayfield Township Building & Zoning Department page, building permit application, permit information sheet and residential fee list were read for a local rule and were read for a local rule and state nothing further on impact resistance.
Repair permit threshold
Mayfield Township publishes no size or cost point below which roof work needs no permit, and its Building & Zoning Department page, building permit application, permit information sheet and fee list name no roofing work and no repair exemption. The application lists "Alter/Remodel" among the things a permit can be for, and the residential fee list has a "HOME REMODELING" line and no roofing line. State law supplies the general rule: "Except as otherwise provided in the code, 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." (MCL 125.1510(1)), and "A building permit is not required for ordinary repairs of a building or structure." (MCL 125.1510(7)), without a definition of ordinary repairs. For a roof repair of any size, ask the Building Department at 810-664-0821 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." The Mayfield Township Building & Zoning Department page, building permit application, permit information sheet and fee list state no layer rule of their own. No township building ordinance was found on the township's website, so none was read for this record.
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 Mayfield Township Building & Zoning Department page, building permit application, permit information sheet and residential fee list were read for a local rule and were read for a local rule and state nothing further on roof decks or 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 Mayfield Township Building & Zoning Department page, building permit application, permit information sheet and residential fee list were read for a local rule and changes this.
