Roofing questions: Township of Prairieville, MI

Do you need a permit to replace a roof in Township of Prairieville, MI?

Yes, a permit is required to replace a roof in Township of Prairieville, MI. Prairieville Township has published nothing on reroofs. Its website has no building permit page, application or fee schedule, and its Zoning Ordinance (current through Ordinance No. 171, December 23, 2020) says only that a "Building Permit" is "A permit issued by the Building Inspector as required by the Building Code regulations" and that "A Building Permit is not a Zoning Permit." The Zoning Ordinance also says "Roofing, siding, insulation, etc. shall not be construed to be a change in the exterior dimension", a zoning definition of "alter" that says nothing about building permits. The township states no size, square or dollar point below which roof work needs no permit. 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, and the township has published nothing applying that relief to roof work.

Is ice & water shield required in Township of Prairieville, MI?

Yes. 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 Prairieville Township website, its Zoning Ordinance and its Ordinances Nos. 8, 9, 30 and 32 were read for a local rule and state nothing further on ice barrier. Prairieville Township's codified building ordinance, Ordinance No. 32 (adopted January 11, 1984), adopts by reference "BOCA Basic Building Code, 1984 Edition"; this field states the 2015 Michigan Residential Code, which the state act applies throughout the state; Prairieville Township has published no statement naming the edition it enforces; the BOCA code text was not read (see adopted_code).

Is drip edge required in Township of Prairieville, MI?

Yes. 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 Prairieville Township website, its Zoning Ordinance and its Ordinances Nos. 8, 9, 30 and 32 were read for a local rule and state nothing further on drip edge. Prairieville Township's codified building ordinance, Ordinance No. 32 (adopted January 11, 1984), adopts by reference "BOCA Basic Building Code, 1984 Edition"; this field states the 2015 Michigan Residential Code, which the state act applies throughout the state; Prairieville Township has published no statement naming the edition it enforces; the BOCA code text was not read (see adopted_code).

Can you roof over an existing roof in Township of Prairieville, MI?

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 ordinances were read: Ordinance No. 8 (1974 Building Code), No. 9 (its first amendment), No. 30 (dangerous buildings) and No. 32 (Building Code). None states a reroofing rule of its own, but Ordinance No. 9 amends and repeals sections of the 1970 BOCA code whose text was not read, and the BOCA codes the ordinances adopt were not read, so this record declares no layer classification. The township's Zoning Ordinance was searched for roof text and has no rule on roof coverings. Prairieville Township's codified Ordinance No. 32 adopts "BOCA Basic Building Code, 1984 Edition"; this field states the 2015 Michigan Residential Code, which the state act applies throughout the state; Prairieville Township has published no statement naming the edition it enforces; the BOCA code text was not read (see adopted_code).

Do roofing contractors need a license or registration in Township of Prairieville, MI?

Yes.

What building code does Township of Prairieville, MI use?

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." Locally, the township's Ordinance No. 32 (adopted January 11, 1984) adopts by reference "BOCA Basic Building Code, 1984 Edition", and its Ordinance No. 8 (adopted September 16, 1974) adopted "The BOCA Basic Building Code, 1970 Edition," as amended by a 1973 cumulative supplement, which Ordinance No. 9 (adopted October 21, 1974) then amends; none of the three names a Michigan residential code edition. The township's Zoning Ordinance (current through December 23, 2020) defines "Building Code" as "The building or construction code in effect in Prairieville Township" and names no edition. LARA's Statewide Jurisdiction List names the Township of Prairieville as its own building code enforcer. This record states the 2015 Michigan Residential Code, which the state construction code act applies throughout the state ("This act and the code apply throughout the state," MCL 125.1508a) and which LARA says remains in effect while the Court of Claims order of July 7, 2025 stands. Prairieville Township has published no statement naming the edition it enforces, and the BOCA code text was not read.
