Township of Summerfield - Zoning and Building Inspection

Yes, a permit is required to replace a roof in Township of Summerfield, MI, issued by Township of Summerfield - Zoning and Building Inspection. In Summerfield Township a reroof is applied for on the township's Application for Plan Examination and Building Permit, which lists "Tearoff/Reroof" among its Type of Improvement boxes and asks for the cost of improvement, a description of the work, and the contractor's "Builders License number" and "Workers Comp. Ins. Carrier or Reason for Exemption". The form says the application is returned to Summerfield Township at 15 E. Center Street, PO Box 98, Petersburg MI 49270, with a check payable to Summerfield Township, and its header names the Building Inspector and Zoning Administrator. The township's residential permit and inspection fee schedule, dated 06/15/2015, is keyed to the valuation of the work (from $60.00 for a valuation of $1 to $2,000), lists a "Re-Inspection Fee" of $60.00, and has no roofing line; confirm the current fee with the township hall. The Building, Electric & Plumbing page lists a building inspector, an electrical inspector and a mechanical and plumbing inspector by title, each with a cell number, and the township hall at 15 E. Center St., Petersburg, is open "Monday - Thursday 9AM - 12PM", office telephone 734-279-1214. The Zoning Ordinance, Section 18.50, requires a building permit from the Township Clerk or designate for structural changes or repairs. No online permit portal is posted.

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: Summerfield Township publishes no contractor registration or licence of its own: its building permit application asks for the contractor's "Builders License number" and expiration date and for the contractor's workers compensation carrier or the reason for exemption, and its Building, Electric & Plumbing, Forms & Ordinances and Zoning Ordinance pages name no township registration.
Permit process note
In Summerfield Township a reroof is applied for on the township's Application for Plan Examination and Building Permit, which lists "Tearoff/Reroof" among its Type of Improvement boxes and asks for the cost of improvement, a description of the work, and the contractor's "Builders License number" and "Workers Comp. Ins. Carrier or Reason for Exemption". The form says the application is returned to Summerfield Township at 15 E. Center Street, PO Box 98, Petersburg MI 49270, with a check payable to Summerfield Township, and its header names the Building Inspector and Zoning Administrator. The township's residential permit and inspection fee schedule, dated 06/15/2015, is keyed to the valuation of the work (from $60.00 for a valuation of $1 to $2,000), lists a "Re-Inspection Fee" of $60.00, and has no roofing line; confirm the current fee with the township hall. The Building, Electric & Plumbing page lists a building inspector, an electrical inspector and a mechanical and plumbing inspector by title, each with a cell number, and the township hall at 15 E. Center St., Petersburg, is open "Monday - Thursday 9AM - 12PM", office telephone 734-279-1214. The Zoning Ordinance, Section 18.50, requires a building permit from the Township Clerk or designate for structural changes or repairs. No online permit portal is posted.
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 Summerfield, Monroe County, as a local building code enforcer for building, electrical, mechanical and plumbing, and lists a different Township of Summerfield, in Clare County, separately. The township's Zoning Ordinance (amended through July 4, 2023) refers to "the adopted building code of the Township" and "the Township Building Code" and names no edition; its building permit application names none either. The township has posted no building ordinance, so no codified building text was read.
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). Summerfield Township's Building, Electric & Plumbing page, its Forms & Ordinances page, its building permit application and fee schedule and its Zoning Ordinance (amended through July 4, 2023) 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). Summerfield Township's Building, Electric & Plumbing page, its Forms & Ordinances page, its building permit application and fee schedule and its Zoning Ordinance (amended through July 4, 2023) 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." Summerfield Township's Building, Electric & Plumbing page, its Forms & Ordinances page, its building permit application and fee schedule and its Zoning Ordinance (amended through July 4, 2023) were read for a local rule and state nothing further on impact resistance.
Repair permit threshold
Summerfield Township treats a tear-off or reroof as its own category of building permit work. Its Application for Plan Examination and Building Permit, posted under Permits on its Forms & Ordinances page, lists "Tearoff/Reroof" as a separate Type of Improvement (box 6), beside New Building, Addition, Alteration and "Repair, replacement", and the township has published no size, area or dollar point below which a reroof needs no permit. The township's Zoning Ordinance, Section 18.50, says it is unlawful to begin "structural changes, or repairs in any existing building, without first obtaining a building permit from the Township Clerk, or designate", and defines repair to exclude "minor repairs or changes not involving any of the aforesaid provisions". 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, no township building ordinance or ordinance list entry for a building code is posted on the township's Forms & Ordinances page (its listed ordinances cover blight, burning, cemeteries, drug paraphernalia, the fire department, marihuana, noise and public nuisance, traffic, truck routes, waste, land division and zoning), so no local building ordinance was read and no layer classification is declared here. The township's permit application states no layer limit.
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). Summerfield Township's Building, Electric & Plumbing page, its Forms & Ordinances page, its building permit application and fee schedule and its Zoning Ordinance (amended through July 4, 2023) 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 Summerfield Township's permit application or pages changes this.

Center Street in Petersburg, issues building permits through a building inspector who is also the zoning administrator, and the township lists separate electrical and mechanical/plumbing inspectors. The State of Michigan's jurisdiction list names the Township of Summerfield, Monroe County, as its own building code enforcer. This record is not Summerfield Township in Clare County.
