Roofing questions: Charter Township of Hampton, MI

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

Yes, a permit is required to replace a roof in Charter Township of Hampton, MI. Hampton Township publishes no size or dollar line below which roof work needs no permit, and no statement that a reroof is exempt. State law requires that "before construction of a building or structure, the owner, or the owner's builder, architect, engineer, or agent, shall submit an application in writing to the appropriate enforcing agency for a building permit" (MCL 125.1510(1)), defines construction to mean "the construction, erection, reconstruction, alteration, conversion, demolition, repair, moving, or equipping of buildings or structures" (MCL 125.1502a(n)), and says "A building permit is not required for ordinary repairs of a building or structure." (MCL 125.1510(7)) without defining ordinary repairs; the permit exemptions in the Michigan Residential Code name no roofing. The township's building permit application offers "Alteration" and "Repair" as work types and prices permits by estimated building cost, starting at $30.00 for work valued from $1.00 to $500.00; its 2025 fee schedule has no roofing line. Plan on a permit for a reroof in Hampton Township and confirm with the building inspector.

Is ice & water shield required in Charter Township of Hampton, 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). Hampton Township Uniform Codes Ordinance No. 31-13 (read in full) states nothing further on ice barrier. Hampton Township's codified Ordinance No. 31-13 Sec. II adopts the 2003 Michigan Residential Code; this field states the 2015 Michigan Residential Code, which the state act applies throughout the state and which Hampton Township's Building Inspection page says it enforces by reference to the state codes "as promulgated and adopted by the Bureau of Construction Codes"; the 2003 Michigan Residential Code text was not read (see adopted_code).

Is drip edge required in Charter Township of Hampton, 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). Hampton Township Uniform Codes Ordinance No. 31-13 (read in full) states nothing further on drip edge. Hampton Township's codified Ordinance No. 31-13 Sec. II adopts the 2003 Michigan Residential Code; this field states the 2015 Michigan Residential Code, which the state act applies throughout the state and which Hampton Township's Building Inspection page says it enforces by reference to the state codes "as promulgated and adopted by the Bureau of Construction Codes"; the 2003 Michigan Residential Code text was not read (see adopted_code).

Can you roof over an existing roof in Charter Township of Hampton, 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." The township's own building ordinance, Hampton Township Uniform Codes Ordinance No. 31-13, was read in full: it adopts the state residential code by reference, amends only sections of the International Fire Code, and touches nothing in the reroofing section, so the state limit applies unchanged. Hampton Township's codified Ordinance No. 31-13 Sec. II adopts the 2003 Michigan Residential Code; this field states the 2015 Michigan Residential Code, which the state act applies throughout the state and which Hampton Township's Building Inspection page says it enforces by reference to the state codes "as promulgated and adopted by the Bureau of Construction Codes"; the 2003 Michigan Residential Code text was not read (see adopted_code).

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

Yes.

What building code does Charter Township of Hampton, 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 Hampton as its own building code enforcer. Hampton Township's codified Uniform Codes Ordinance Sec. II (Ordinance No. 31-13; the posted copy prints no adoption date) adopts "the 2003 Michigan Residential Code"; this directory has not read that text, and whether the codified reference has any effect today is not decided here. 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. Hampton Township's Building Inspection page, read October 3, 2026, says "The Township enforces the State Building, Plumbing, Mechanical and Electrical Codes as promulgated and adopted by the Bureau of Construction Codes."
