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 Windsor Charter Township Building Department asks licensed contractors to register: "In order to effectively and efficiently process permit applications for licensed contractors, we ask that licensed individuals register with the Township." It adds "This is not required and no fee is associated with the registration." and says "Non-registered applicants will be asked to produce evidence of appropriate license held for each permit application completed prior to issuance." The department's licensing sheet states "A RESIDENTIAL BUILDERS LICENSE IS REQUIRED FOR RESIDENTIAL BUILDERS DOING WORK ON ANY HOME THAT IS NOT THEIR OWN FOR REMODELS, REPAIRS AND NEW BUILDS", citing the state construction code act and the Occupational Code. This record does not decide whether a given roofer falls inside a state exemption.
Permit process note
In Windsor Charter Township the Building Department takes permit applications on its Building Permit Application, which asks the contractor for a state of Michigan licence number and expiration date, a federal employer ID number (or reason for exemption), and a workers' compensation carrier (or reason for exemption), and says "Building work shall not be started until the permit has been issued". The department's page says "Structural, electrical, plumbing and mechanical work covered under the Michigan Building Code is not to be commenced without approval of permit and inspection of work performed under said permit." Fees are set by a township board fee schedule: the application's office-use block shows an "Administration Fee: $65.00" and the fee schedule charges "$60.00 per required inspection and reinspection." The page says the department is "available in person from 9:00 A.M. to 4:00 P.M. on Tuesday and Thursday" at 300 W. Jefferson St. (rear entrance) and can be reached at 517.919.1566, option 5, with mail to P.O. Box 518, Dimondale, MI 48821. To schedule an inspection for an approved permit, leave the property address and permit number, and the page says "You will receive a return telephone call confirming what day the inspection is anticipated to occur." The page says the township's jurisdiction "DOES NOT include the Village of Dimondale". No online permit portal is posted on the page.
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 Windsor Township as its own building code enforcer. The township's Ordinance No. 50, the Michigan Construction Code Ordinance adopted May 14, 2024, says "the Township hereby assumes responsibility for the administration and enforcement of the international residential code" and the other state construction codes, and names no edition. The department's page says it reviews and inspects work "defined under the Michigan Building Code" and names no edition of the residential code, and the township has published no statement of which edition it enforces. The township's zoning ordinance is the only code of ordinances it posts on Municode.
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 Windsor Charter Township Building Department's page, Building Permit Application, permitting and inspections sheet and fee schedule, and Ordinance No. 50, were read for a local rule and state nothing further on drip edge. About 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 Windsor Charter Township Building Department's page, Building Permit Application, permitting and inspections sheet and fee schedule, and Ordinance No. 50, 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 Windsor Charter Township Building Department's page, Building Permit Application, permitting and inspections sheet and fee schedule, and Ordinance No. 50, were read for a local rule and state nothing further on impact resistance.
Repair permit threshold
No size or cost threshold for roof work is published. The Windsor Charter Township Building Department's page, its Building Permit Application, its permitting and inspections sheet and its fee schedule say nothing about reroofing. The department's page says "Structural, electrical, plumbing and mechanical work covered under the Michigan Building Code is not to be commenced without approval of permit and inspection of work performed under said permit." The application's Purpose of Project choices include alteration and repair, and the fee schedule prices "Alterations (based on written contract cost)" at "$8.00 per $1,000.00 cost"; it has no roofing line. 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 a reroof, call the Building Department at 517-919-1566, option 5, 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, no layer rule was found. Windsor Charter Township's Ordinance No. 50, its construction code ordinance, was read in full: it assumes responsibility for enforcing the state construction codes, appoints a building official, issues permits under a township fee schedule, creates a construction code board of appeals and sets penalties, and it has no reroofing provision and amends nothing in Section R908. The township's other posted ordinances on dangerous buildings, public nuisance, civil infractions and the earlier fire code are scanned pages that were not read in full, so this record states no layer classification. The Building Department's page, Building Permit Application and fee schedule 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 Windsor Charter Township Building Department's page, Building Permit Application, permitting and inspections sheet and fee schedule, and Ordinance No. 50, 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 Windsor Charter Township Building Department's page or Building Permit Application changes this.
