Roofing questions: Fenton, MI

Do you need a permit to replace a roof in Fenton, MI?

Yes, a permit is required to replace a roof in Fenton, MI. No size or cost threshold is published. Fenton's Building Information page says "a permit will be required for all roof and siding work done in the City of Fenton", with no exception for small repairs, and Chapter 6 of the Fenton Code of Ordinances (Buildings and Building Regulations), read in full, sets no repair threshold of its own. The state part: Michigan's construction code act says "A building permit is not required for ordinary repairs of a building or structure" and does not define ordinary repairs; the City's "all roof and siding work" line names no exception for them. For a small roof repair, call the department (810-629-2261) before starting.

Is ice & water shield required in Fenton, 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 City of Fenton's building pages, fee schedule and Chapter 6 of its code were read for a local rule and state nothing further on ice barrier; the City's residential permit application asks new-construction drawings to show "Roof construction details, size, and type of sheathing, felt paper, ice and water shield, shingles, drip edge."

Is drip edge required in Fenton, 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 City of Fenton's building pages, fee schedule and Chapter 6 of its code were read for a local rule and state nothing further on drip edge; the City's residential permit application asks new-construction drawings to show "Roof construction details, size, and type of sheathing, felt paper, ice and water shield, shingles, drip edge."

Can you roof over an existing roof in Fenton, 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 City's own building ordinance, Chapter 6 of the Fenton Code of Ordinances (Buildings and Building Regulations, which adopts the 2021 property maintenance code, designates the enforcing agency and sets rental certificates of compliance), was read in full: it has no roofing provision and amends nothing in Section R908, and the City's permit pages and fee schedule state no layer rule.

Do roofing contractors need a license or registration in Fenton, MI?

Yes.

What building code does Fenton, 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 City's Building Codes page lists "Michigan Residential Code 2015" for detached one- and two-family dwellings, and Section 6-17 of the Fenton Code of Ordinances designates the Building Official as the enforcing agency under the state construction code act. The City's older Residential Guidelines handout still names "MICHIGAN RESIDENTIAL CODE 2003" as the City Building Code; the Building Codes page is the City's current statement of the edition it enforces.
