City of Flushing - Building Department

Yes, a permit is required to replace a roof in Flushing, MI, issued by City of Flushing - Building Department. In the City of Flushing a reroof goes through a building permit: the Building Inspector page says "As of July 1, 2017, the City of Flushing will require a building permit to install new/replacement windows, siding and or shingles/new roof." and "Application forms for building permits may be obtained through this web site or at Flushing City Hall located at 725 East Main Street, Flushing, Michigan 48433." The city's Residential Re-roofing guide, a handout published by SAFEbuilt and dated July 1, 2017, says the owner may do the re-roof ("May I, as the owner, do the re-roof myself?" "Yes."), says "Yes, the permit holder must call for a Final Roof inspection. There may be a mid-roof inspection required, please consult the Building Department when you receive your permit.", and says to schedule an inspection by calling the number listed on the permit card. The building permit application asks for a builder's license number, a federal employer ID number or reason for exemption, a workers compensation carrier and a UIA number or reason for exemption, and says "Separate Applications Must be Completed for Plumbing, Mechanical and Electrical Work Permits"; the Building Inspector page says "All trade permits (Plumbing / Electrical / Mechanical) are handled by the State of Michigan". Fees are set by the city's construction permit fee schedule effective October 1, 2019, which the city's December 8, 2025 schedule of fees still cites for building permits: "Miscellaneous Construction/Repairs" is "$39.00 +1B" and, where zoning review is required, "$27.00" is added, with "1B" set at "$9.50 per $1000 dollars in construction value" measured from the ICC Building Valuation Data. The schedule has no roofing line, so confirm the fee for a reroof with the department. The Building Inspector page lists a Building Inspector at (810) 262-0623 and a Permit Clerk at (810) 347-0435, and City Hall, (810) 659-5665, is open Monday through Friday, 9am to 4:30pm.

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 City of Flushing Building Inspector page and building permit application were read and describe no city contractor registration; the application asks for the contractor's builder's license number, federal employer ID number or reason for exemption, workers compensation carrier and UIA number or reason for exemption.
Permit process note
In the City of Flushing a reroof goes through a building permit: the Building Inspector page says "As of July 1, 2017, the City of Flushing will require a building permit to install new/replacement windows, siding and or shingles/new roof." and "Application forms for building permits may be obtained through this web site or at Flushing City Hall located at 725 East Main Street, Flushing, Michigan 48433."

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 City of Flushing as its own building code enforcer. Chapter 150 of the city's Code of Ordinances designates the building official as the enforcing agency under the state construction code act and names no edition of the residential code, and the city's building permit application heads its residential section "BUILDINGS REGULATED BY THE MICHIGAN RESIDENTIAL CODE" without naming an edition. The city's Property Maintenance Code, Sec. 150.65, adopts the International Property Maintenance Code, 2021 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). The city's Residential Re-roofing guide, a SAFEbuilt handout dated July 1, 2017, says "Drip edge is required around entire perimeter of roof.", which matches the state rule. The City of Flushing Building Inspector page, its Residential Re-roofing guide, its construction permit fee schedule and Chapter 150 of its Code of Ordinances were read for a local rule and state nothing further on drip edge beyond that guide. 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 city's Residential Re-roofing guide lists underlayment for complete tear-offs without mentioning an ice barrier. The City of Flushing Building Inspector page, its Residential Re-roofing guide, its construction permit fee schedule and Chapter 150 of its Code of Ordinances 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 City of Flushing Building Inspector page, its Residential Re-roofing guide, its construction permit fee schedule and Chapter 150 of its Code of Ordinances were read for a local rule and state nothing further on impact resistance.
Repair permit threshold
The City of Flushing's Building Inspector page says "As of July 1, 2017, the City of Flushing will require a building permit to install new/replacement windows, siding and or shingles/new roof." and its Residential Re-roofing guide asks "Why do I need a permit to re-roof my house?" The city publishes no size or cost point below which roof work needs no permit. Its building permit application, in its section for alteration, repairs and additions, gives "20,000 sq. ft. roof covering" as an example of work to be covered by the building permit, and its construction fee schedule has a "Miscellaneous Construction/Repairs" line for work requiring no structural changes, with 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 small roof repair, ask the Building Inspector (810-262-0623) 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, Chapter 150 of the City of Flushing Code of Ordinances (Building Regulations) was read in full: it designates the enforcing agency, sets fees by council resolution, designates flood hazard areas and adopts a property maintenance code; it has no reroofing provision and amends nothing in Section R908. The city's Residential Re-roofing guide, a SAFEbuilt handout dated July 1, 2017, answers "How many layers of roofing are allowed?" with "A maximum of two layers.", which matches the state rule, and lists four conditions for removing the old roof before re-covering, the fourth being "Asphalt shingles subject to moderate or severe hail exposure."; that item is not among the conditions in Section R908.3.1.1 of the 2015 code, and no local ordinance adopting it was found, so ask the Building Department whether it applies to a given roof.
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 city's Residential Re-roofing guide says, for complete tear-offs, "The roof sheathing must provide a rigid surface." and "Repair or replace all boards or sheathing which are warped, cracked or delaminated between supports.", which fits the state rule. The City of Flushing Building Inspector page, its Residential Re-roofing guide, its construction permit fee schedule and Chapter 150 of its Code of Ordinances were read for a local rule and state nothing further on roof decks or sheathing beyond that guide.
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 City of Flushing Building Inspector page changes this.
