The township's published permit material says nothing specific about roof work: the Building Permits page, the Requirements for Obtaining Building Permits sheet and the building permit application name no roofing line and no reroof exemption. With the township silent on reroofs, the general rules apply. Section 19.3(a) of the township's zoning ordinance makes it "unlawful for any person to commence excavation for, construction of any building or structure, structural changes, or repairs in any existing building or structure, or moving of an existing building, without first obtaining a Building Permit from the Building Inspector" and excepts "minor repairs or changes not involving any of the aforesaid provisions", and the state's permit rule says "A building permit is not required for ordinary repairs of a building or structure," without defining ordinary repairs; the township has published nothing applying either relief to roof work. The Building Permits page says "All permit applications and payments may be paid either by mail or in person to the Building Inspector" and "Each permit requires separate payment", and its heading reads "Building Permits Cannot Be Submitted By Email". Fees are not posted: the township says "Building permit fees may be obtained from the LaSalle Building Department, by calling the Building Division, (734) 241-4344", and asks for the total square footage, the use group and the type of construction when calling.

Permit process note
The township's published permit material says nothing specific about roof work: the Building Permits page, the Requirements for Obtaining Building Permits sheet and the building permit application name no roofing line and no reroof exemption. With the township silent on reroofs, the general rules apply. Section 19.3(a) of the township's zoning ordinance makes it "unlawful for any person to commence excavation for, construction of any building or structure, structural changes, or repairs in any existing building or structure, or moving of an existing building, without first obtaining a Building Permit from the Building Inspector" and excepts "minor repairs or changes not involving any of the aforesaid provisions", and the state's permit rule says "A building permit is not required for ordinary repairs of a building or structure," without defining ordinary repairs; the township has published nothing applying either relief to roof work.

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 Township of La Salle as its own building code enforcer. The township's building permit application is a state form that cites "Authority: 1972 PA 230", offers "Buildings Regulated by the Michigan Residential Code" and "Buildings Regulated by the Michigan Building Code" as plan review categories, and asks for a method of compliance with the "Michigan Uniform Energy Code", and none of these names an edition. The township's zoning ordinance, Ordinance No. 55 as amended through November 2024, refers to "the LaSalle Township Building Code" and "the Township Building Code" without an edition, and the ordinance adopting that building code is not among the documents posted on the township's website, so its text was not read. The township has published no statement of which residential code edition it enforces. 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.
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 La Salle Township Building Permits page, its permit forms and its zoning ordinance were checked for a local rule and state nothing further on drip edge.
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 La Salle Township Building Permits page, its permit forms and its zoning ordinance were checked for a local rule and state nothing further on ice barrier.
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 La Salle Township Building Permits page, its permit forms and its zoning ordinance were checked for a local rule and state nothing further on impact resistance.
Repair permit threshold
La Salle Township has published nothing that applies a permit or an exemption to roof work: its Building Permits page, its Requirements for Obtaining Building Permits sheet and its building permit application name no roofing line, no reroof exemption and no size or dollar point below which a repair needs no permit, and the application offers "ALTERATION" and "REPAIR" among its types of improvement without defining either. Its zoning ordinance, Ordinance No. 55, says "It shall be unlawful for any person to commence excavation for, construction of any building or structure, structural changes, or repairs in any existing building or structure, or moving of an existing building, without first obtaining a Building Permit from the Building Inspector", and defines repair to include "any other changes affecting or regulated by the Building Code, the Housing Law of the State of Michigan, or this Ordinance, except for minor repairs or changes not involving any of the aforesaid provisions", without defining minor repairs. 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. The township's fee instructions say "Building permit fees may be obtained from the LaSalle Building Department, by calling the Building Division, (734) 241-4344", so for any roof work, large or small, call the township at 734-241-4344, extension 306, before starting.
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, no building ordinance or building code is posted: the township's website lists no ordinances page, the zoning ordinance (Ordinance No. 55, amended through November 2024) refers to a "Township Building Code" whose text is not posted, and the zoning ordinance itself was searched for roofing text and uses "roof" only in definitions, height and setback provisions and its solar provisions. No classification is declared here. The Building Permits page, the requirements sheet and the permit application state no layer rule.
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 La Salle Township Building Permits page, its permit forms and its zoning ordinance were checked for a local rule and state nothing further on roof sheathing.
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 La Salle Township Building Permits page or in its permit forms changes this.
