Roofing questions: Township of Locke, MI

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

Yes, a permit is required to replace a roof in Township of Locke, MI. Locke Township's Building Permit application for accessory buildings and demolition lists "Re-Roofing" among the types of work, and its list of what to submit has a "Roof Repair" entry: "Drawings of Work to be Performed that includes but not limited to: Roof covering materials, Number of layers, Decking, Roof venting, Flashing, other structural / construction, ETC." The township publishes no exemption for reroofing and no dollar threshold below which a roof job needs no permit. State law also says "A building permit is not required for ordinary repairs of a building or structure." (MCL 125.1510), without defining ordinary repairs; the township's own form box and submittal list treat re-roofing and roof repair as permit work.

Is ice & water shield required in Township of Locke, 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 Building Permit applications, the Minimum Requirements sheet and the township's ordinances were read for a local rule and state nothing further on ice barrier.

Is drip edge required in Township of Locke, 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 Building Permit applications, the Minimum Requirements sheet and the township's ordinances were read for a local rule and state nothing further on drip edge.

Can you roof over an existing roof in Township of Locke, 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 ordinance index was read: it lists the Locke Township Zoning Ordinance (a file named for 2015), a new zoning ordinance posted as "2026 Zoning Ordinance - DRAFT" whose cover reads "Adopted October 13, 2026", an off-road vehicle ordinance, a cemetery ordinance, solar, wind, marijuana, gas franchise and rezoning ordinances and their amendments, and no building or construction code ordinance. The 2026 draft was searched in full and has no reroofing provision and nothing that amends Section R908; the 2015 Zoning Ordinance was not read, so this record sets no layer classification. The Building Permit application asks for the "Number of layers" with a Roof Repair submittal and states no layer limit.

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

Yes.

What building code does Township of Locke, 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." LARA's Statewide Jurisdiction List names the Township of Locke as its own building code enforcer. The township's Building Permit applications, its Minimum Requirements sheet and the new zoning ordinance it posts as "2026 Zoning Ordinance - DRAFT" (whose cover reads "Adopted October 13, 2026"), read October 15, 2026, name no edition of any residential code; its 2015 Zoning Ordinance was not read.
