Charter Township of Port Huron - Building Department
Yes, a permit is required to replace a roof in Charter Township of Port Huron, MI, issued by Charter Township of Port Huron - Building Department. In Port Huron Charter Township a permit is applied for before work starts: the Building Department says "Permits must be delivered, faxed or emailed to the Township Building Department prior to work starting." and that "Municipal Civil Infraction fines will be issued when a permit has not been submitted to and approved by the Building Department prior to the start of work." The 2026 Building Permit Application asks for the estimated project cost and says "The first $100.00 of an application is non-refundable"; it charges $75.00 to re-open an expired permit and $50.00 for a re-inspection. It says "Building work shall not be started until the permit has been issued by the Charter Township of Port Huron." and "No work shall be concealed until it has been inspected.", and that the inspector will respond to an inspection request "within two (2) business days to schedule the inspection." A permit becomes invalid if work does not start within 180 days of issuance or stops for 180 days. The fee schedule, effective January 1, 2026, prices a building permit for work up to $1,000 at $75.00 and from $1,000 to $10,000 at "75.00 plus $10 per $1,000 over $1,000". The department is at 3800 Lapeer Road, Port Huron Township, MI 48060, 810-987-6600, open Monday to Friday 8:30 to 4:30; the page lists the Building Official at (810) 300-3421.

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 Charter Township of Port Huron as its own building code enforcer. The township's 2026 Building Permit Application says "All installations shall be in compliance with the Michigan Building Codes." and its form for one- and two-family work reads "Residential - Buildings Regulated by the Michigan Residential Code", naming no edition. The township's code of ordinances is published on Code Publishing, which served a browser challenge to this directory's research client, so the township's building code chapter was not read for this record.
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). The township's Building Department page and 2026 Building Permit Application were read for a local rule and state nothing further on drip edge; the township's building code chapter was not read.
About drip edgeIce & 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). The township's Building Department page and 2026 Building Permit Application were read for a local rule and state nothing further on ice barrier; the township's building code chapter was not read.
About ice & water barrierImpact-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." The township's Building Department page and 2026 Building Permit Application were read for a local rule and state nothing further on impact resistance; the township's building code chapter was not read.
Repair permit threshold
Port Huron Charter Township's Building Department says "Please be aware that Permits for Building, Electrical, Plumbing, and Mechanical work are required to be submitted and approved prior to the start of any work." and "Please feel free to call the Township with any questions you may have." Its 2026 Building Permit Application lists "ALTERATION" and "REPAIR" among the purposes of a project, with no roofing choice, and its 2026 fee schedule prices building permits by the cost of the work, starting at "to $1,000 (includes one inspection only)" for $75.00, with no roofing line. The township has published nothing about reroofs and no size, square or dollar point below which roof work needs no permit. 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 township has published nothing applying that relief to roof work.
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, the Building Department page, the 2026 Building Permit Application and the 2026 fee schedule state no layer rule. The township's code of ordinances is published on Code Publishing, which served a browser challenge to this directory's research client, so the township's building code chapter was not read for this record. This record therefore states the state rule and does not say that no local amendment exists.
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). The township's Building Department page and 2026 Building Permit Application were read for a local rule and state nothing further on roof sheathing; the township's building code chapter was not read.
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 the Port Huron Charter Township Building Department page or in its 2026 fee schedule changes this.
