Roofing questions: Muskego, WI

Do you need a permit to replace a roof in Muskego, WI?

Yes, a permit is required to replace a roof in Muskego, WI. ROOFING IS NAMED IN THE ORDINANCE, ON THE PERMIT PAGE, ON THE FEE SCHEDULE AND ON THE APPLICATION FORM - THIS IS NOT AN INFERENCE. Municipal Code section 164-6A provides that "No building or structure, or any part thereof, shall hereafter be built, enlarged, altered or demolished within the municipality or moved into, within or out of the municipality except as hereinafter provided, unless a permit therefor shall first be obtained by the owner or his agent from the Building Inspector," and its list of permits required includes, as item (6), "Re-roofing and re-siding." The City permit page carries the same item on its list of work for which "Building Permits are required," in these words: "Re-Roofing and Re-Siding - Minor repairs may not require permits, contact inspector to discuss your specific project." The building permit application prints Re-Roofing as one of the tick-boxes for type of project. So the threshold question in Muskego is not whether a reroof needs a permit but where a small repair stops being one, and the City answers that with a phone call rather than a number: there is no square-footage or dollar threshold published, and the instruction is to contact the inspector on (262) 679-4037. READ THE ORDINANCE'S MINOR-REPAIR CLAUSE CAREFULLY, BECAUSE IT IS NOT A PERMIT EXEMPTION. Section 164-3C(4)(b) defines repairs that do not involve structural portions or affect room arrangement, light and ventilation, exits, fire protection, heating or air conditioning, insulation or energy efficiency, plumbing, electrical, or exterior aesthetic appearance, and which do not increase occupancy and use, as "minor repairs, exempt from plan submittal requirements" - an exemption from submitting plans, not from the permit. Two further local rules bear on a reroof. Section 164-3C(3)(b)[1] provides that the code applies to "An existing structure that is repaired, when the cost of such repairs during the life of the structure exceeds 50% of the equalized value of the structure," and notes that repair work below that threshold "shall be required to comply with the code that was in effect when the component or work was originally constructed." Section 164-3C(3)(b)[2] then says what counts toward that cost: "only structural work which extends the life of the structure shall be included, such as rafters, decking, headers, foundations, studs, etc.," while doors, windows, plumbing, electrical, carpet, paint and trim do not. Roof decking is on the counting side of that line. The fee is value-based: "Re-Roofing, Re-Siding, Foundation Repair, Projects Where a Square Footage Cannot be Determined - Building Permit fee - $10 per $1,000 of value (minimum of $125)," on top of a minimum base fee of $70, under the fee updates the Common Council approved on January 14, 2025 and made effective April 18, 2025. And the penalty for skipping it is steeper than most: the City states that "Triple permit fees will be assessed if work is started without a valid permit."

Is ice & water shield required in Muskego, WI?

Yes. STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Muskego adds nothing to this: Chapter 164 Article I of the Municipal Code was read in full and contains no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose - ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Muskego has closed the older-house branch of that scope question, and it did it in an unusual way that a roofer should see in the City's own words rather than in a summary. Municipal Code section 164-3B provides that "The Wisconsin Uniform Dwelling Code, Chs. SPS 320 through 325, Wis. Adm. Code, inclusive, and all amendments thereto and the Wisconsin Uniform Building Code are hereby made a part of this code by reference and shall apply to all one- and two-family dwellings and alterations and additions thereto," with no cut-off by the age of the house, and then adds: "For purposes of this code, the Wisconsin Uniform Building Code shall apply to alterations and additions to all one- and two-family dwellings constructed prior to the effective date of the Wisconsin Uniform Dwelling Code." Both sentences are reproduced here as enacted, and which body of rules the second one points to on a particular older house is a question for the Building Inspector, not for this record. Section 164-3C(3)(d) then answers the roofing side of it by name: "Roof coverings. Whenever more than 25% of the roof covering of a building is replaced in any twelve-month period, all roof covering shall be in conformity with applicable sections of this code." So on any reroof past a quarter of the roof, the City's code is engaged whatever the age of the house.

Is drip edge required in Muskego, WI?

No. No drip edge is required by code on a Muskego roof, at either level of government. The statewide Wisconsin uniform dwelling code, unlike the International Residential Code, carries no drip edge requirement: SPS 321.28, "Weather protection for roofs," was read in full - general drainage and fasteners, underlayment for shingles, asphalt shingles, ice dam protection, other roof coverings, reroofing, and every flashing paragraph - and no provision requires a drip edge at an eave or a rake. The only drip edge language anywhere in the Wisconsin dwelling chapter is a masonry chimney cap rule, which is not a roof edge requirement. On the City side, Chapter 164 Article I of the Municipal Code was read in full and the words drip edge do not appear in it, and neither does any other roof-edge or roof-flashing requirement. Practical point for a bid: drip edge may still be required as a matter of the shingle manufacturer installation instructions, which SPS 321.28(3)(a) makes binding for asphalt shingles, so read the wrapper before leaving it off.

Can you roof over an existing roof in Muskego, WI?

STATE-SET. Muskego writes no reroofing layer rule of its own - Chapter 164 Article I of the Municipal Code, all twenty-three sections, was read in full and contains no layer limit, no recover rule and no shingle provision - so the statewide rule governs unmodified. The statewide Wisconsin uniform dwelling code bars installing a new roof covering over the existing covering in three situations: where the existing roof or covering is water-soaked or has deteriorated so that it is inadequate as a base for additional roofing; where the existing roof is wood shake, slate, clay, cement or asbestos-cement tile; or where the existing roof already has two or more applications of any type of permanent roof covering. So at most two total layers, and fewer than that where the deck is wet or deteriorated or the existing roof is one of the listed materials. A complete tear-off to the deck is not restricted by that rule at any layer count. There is no local route past two layers here of the kind some other Wisconsin municipalities publish on calculations submitted to the inspector, so a roof already carrying two applications is a tear-off in Muskego. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose - ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Muskego has closed the older-house branch of that scope question, and it did it in an unusual way that a roofer should see in the City's own words rather than in a summary. Municipal Code section 164-3B provides that "The Wisconsin Uniform Dwelling Code, Chs. SPS 320 through 325, Wis. Adm. Code, inclusive, and all amendments thereto and the Wisconsin Uniform Building Code are hereby made a part of this code by reference and shall apply to all one- and two-family dwellings and alterations and additions thereto," with no cut-off by the age of the house, and then adds: "For purposes of this code, the Wisconsin Uniform Building Code shall apply to alterations and additions to all one- and two-family dwellings constructed prior to the effective date of the Wisconsin Uniform Dwelling Code." Both sentences are reproduced here as enacted, and which body of rules the second one points to on a particular older house is a question for the Building Inspector, not for this record.

Whenever more than 25% of the roof covering of a building is replaced in any twelve-month period, all roof covering shall be in conformity with applicable sections of this code." So on any reroof past a quarter of the roof, the City's code is engaged whatever the age of the house.

Do roofing contractors need a license or registration in Muskego, WI?

Yes. A PAIR OF STATE CREDENTIALS, AND MUSKEGO WILL NOT TAKE THE PERMIT WITHOUT BOTH. State level: Wisconsin requires a contractor credential to obtain a building permit for a one- or two-family dwelling. The contracting business must hold a Dwelling Contractor certification from the Department of Safety and Professional Services, which rests on proof of financial responsibility - a bond or liability insurance, plus worker's compensation and unemployment insurance statements - and must hold or employ someone holding a Dwelling Contractor Qualifier certification, which requires at least 12 hours of approved coursework in construction law, construction codes and construction business practices. A restricted version of the certification is issued to an applicant bonding under 25,000 dollars; that is a bond-size distinction, not a narrower scope of work. There is no separate roofing licence in Wisconsin - a roofer holds the same dwelling contractor credential a framer or a siding contractor holds. An owner who resides or will reside in the dwelling and pulls the permit personally is exempt. Note that the state requirement is written as a condition on obtaining a building permit, and Wisconsin has not settled whether a like-for-like reroof needs a uniform dwelling code permit at all, so ask before assuming it is triggered on a job the municipality does not permit. The certification reaches houses of every vintage: Wis. Stat. 101.615(3) applies the certification sections to a permit application to perform work on a dwelling whose initial construction commenced before, on or after December 1, 1978, so the age carve-out that limits the construction standards does not limit the credential. City level: Muskego enforces the state scheme and issues no roofing credential of its own, but it states the rule more bluntly than most Wisconsin cities. Its Licenses page says: "if a contractor is going to be submitting a permit for building work/construction they need to have a Dwelling Contractor Certification (or Building Contractor Registration) and a Dwelling Contractor Qualification Certification. If they do not have both of these, then they cannot submit for the permit." It also draws the line on who may pull a permit at all: "A non-licensed contractor CANNOT apply for a permit for someone else's property/home," while a homeowner who lives in the home, or is going to, may submit for a building, HVAC or plumbing permit without a licence - with the single exception that "any electrical work has to have the permit submitted by a state licensed electrician." The building permit application prints fields for the contractor's License Number and Qualifier Number with their expiry dates. There is no local roofing licence, no local contractor registration and no local bond for a roofer: Chapter 164 Article I of the Municipal Code was read in full and creates none. Note that a job crossing into electrical, plumbing or HVAC work brings a separate permit and that trade's own state credential with it.

What building code does Muskego, WI use?

STATE CODE, ADOPTED BY THE CITY INSIDE ITS OWN BUILDING CODE. One- and two-family dwellings in Muskego are built to the Wisconsin Uniform Dwelling Code, chs. SPS 320 to 325 of the Wisconsin Administrative Code. That code is Wisconsin's own text rather than an adoption of the International Residential Code, which is why its roofing rules read differently from the IRC and why no IRC edition year applies to a house here. The local instrument is the Muskego Municipal Building Code, Chapter 164 Article I of the City Code. Section 164-3B adopts the dwelling code: "The Wisconsin Uniform Dwelling Code, Chs. SPS 320 through 325, Wis. Adm. Code, inclusive, and all amendments thereto and the Wisconsin Uniform Building Code are hereby made a part of this code by reference and shall apply to all one- and two-family dwellings and alterations and additions thereto." The adoption floats rather than freezing an edition, since it takes "all amendments thereto." Definitions run on the state text as well: section 164-4A applies the definitions in Wis. Admin. Code SPS 320.07 and extends them to non-dwelling structures in the City. Commercial work runs on a different code set - section 164-3A adopts chs. SPS 361 to 366, the Wisconsin Commercial Building Code - and that track is not the subject of the residential fields recorded here. Chapter 164 Article I was read in full, all twenty-three sections, and it adds no roof-assembly requirement of its own; what it does add is local detail on garages, decks, accessory buildings, foundation repairs and permit procedure. The article was adopted 4-20-2006 by Ordinance No. 1222 and its adoption section was last amended 2-4-2010 by Ordinance No. 1312; the codification includes legislation through March 10, 2026.
