Roofing questions: Fond du Lac, WI

Do you need a permit to replace a roof in Fond du Lac, WI?

Yes, a permit is required to replace a roof in Fond du Lac, WI. There is no dollar figure and no square-footage figure in Fond du Lac; the test is what the work does to the building. The City's Inspection Division states plainly that a permit is required for but not limited to new buildings, additions, interior and exterior alterations, siding, roofing, garages, decks, windows, swimming pools, sheds, patios, fences, electrical work, water heater replacements, furnace replacements, plumbing work, signs and all other improvement and/or repairs - roofing is named on the list. The municipal code says the same thing in section 255-4A(1), which requires a building permit from the Building Inspector before anyone may improve, alter, convert, repair or extend any building. The only exemption is section 255-4A(2): this article shall not be construed to require a permit for any repairs or minor alterations which do not change the occupancy, area, structural strength, fire protection, exits, lights or ventilation of a building. On top of that the Division publishes an administrative waiver - permits for minor alterations or maintenance repairs may be waived by the City Building Inspector - and asks that you call (920) 322-3570 to verify whether a permit is needed. Treat a reroof as permitted work and call before assuming a patch is not. Fees run off job cost rather than roof area: the 2026 adopted fee schedule prices residential alterations from $39 for a job of $1,000 or less up to $97 plus $4.00 per each $1,000 over $10,000, every permit carries a $30 minimum, and starting work without a permit doubles the fee for a first offence and triples it for a repeat within a year.

Is ice & water shield required in Fond du Lac, WI?

Yes. Required on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage and that have a slope of 4:12 or less. The protection must be sheet metal or a product labeled as meeting the requirements of ASTM D1970, and it 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. Wisconsin's trigger is the roof slope, not the climate zone, so this is materially narrower than the International Residential Code's ice-barrier rule: a steeper Fond du Lac roof is not caught by it, even though the city gets the ice-dam winters that make one worthwhile. Wisconsin also measures the extent differently from the IRC, so do not substitute IRC ice-barrier language on a Fond du Lac job. The shingle manufacturer's own installation instructions may still require an ice barrier on a steeper roof, and the state code makes those instructions binding for asphalt shingles. Fond du Lac has not added a local ice-barrier requirement of its own: its building code carries no ice or ice-barrier provision anywhere in the building article. 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. In Fond du Lac the first of those two branches is answered by the City's own building code rather than left open. Chapter 255, section 255-2A(1)(a) of the Fond du Lac municipal code adopts chs. SPS 320 through 325 of the Wisconsin Administrative Code and incorporates them into the City's building article by reference, and section 255-2C then provides that every alteration or repair to any part of any existing building shall be made to conform to the requirements of that article for new buildings, except if technically infeasible. So the City has extended these state construction standards to work on existing buildings, including dwellings older than June 1, 1980. The technically-infeasible allowance is the Building Inspector's call on the particular house, so on an older Fond du Lac home confirm the point with the Inspection Division before pricing the work.

Can you roof over an existing roof in Fond du Lac, WI?

Fond du Lac is one of the few Wisconsin cities that writes its own reroofing rule as well as enforcing the state one, so read both. The City's own building code, section 255-9H, headed Reroofing, reads in full: "A new roof covering may be applied on top of an existing roof covering. Not more than two layers of roof covering shall be allowed. Where additional layers of roof materials are requested, calculations shall be submitted to the Building Inspector to demonstrate that the additional layer(s) will not exceed the design load of the roof framing." The Wisconsin Uniform Dwelling Code, which the City has also adopted, bars an overlay in three situations rather than counting layers alone: where the existing roof or roof covering is water-soaked or has deteriorated such 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 has two or more applications of any type of permanent roof covering. Two of those bar a recover over even a single existing layer. Read together, both instruments put the ceiling at two layers: at most two total applications, and fewer than that on a wet or deteriorated deck or over any of the listed materials. The City's calculations sentence runs one way only: it can let a third layer go on where design-load calculations for the roof framing are submitted to the Building Inspector, and it never bars a recover the two-layer count would allow. The state reroofing rule, SPS 321.28(6), itself states no route past two layers. Neither instrument restricts a complete tear-off to the deck. The City's building article also provides, in section 255-1C, that it supplements the laws of the state and the rules of the Department of Safety and Professional Services relating to buildings, and that "Where requirements conflict, the stricter requirements shall govern." This record reports the City subsection, the state rule and that sentence as published and does not decide how they apply to a third layer; ask the Inspection Division before pricing one. 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.

Do roofing contractors need a license or registration in Fond du Lac, WI?

Yes. 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 - proof of financial responsibility, meaning 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 in an approved course in dwelling construction within the year before application, covering construction laws, construction codes and construction business practices. A restricted version of the certification is issued to an applicant bonding under $25,000; 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. The certification requirement is written as a condition on obtaining a building permit rather than on performing the work, and it reaches a dwelling of any vintage, including one built before December 1978, so the age carve-out that narrows the construction standards does not narrow this. City level: Fond du Lac issues no roofing or general-contractor licence of its own. Its permit application states that all contractors shall possess an appropriate contractor credential issued by the Wisconsin Department of Safety and Professional Services and that contractors are also required to only subcontract with contractors that hold appropriate contractor credentials, and the form has fields for the Dwelling Contractor number and Dwelling Qualifier number. The only licence the City issues under its building chapter is an electrical one - a facilities maintenance wiring licence obtained from the Electrical Inspector - which does not reach roofing.

What building code does Fond du Lac, WI use?

One- and two-family dwellings in Fond du Lac are built to the Wisconsin Uniform Dwelling Code, chs. SPS 320 through 325 of the Wisconsin Administrative Code, which is Wisconsin's own text rather than an adoption of the International Residential Code - which is why its roofing rules differ from the IRC's. Do not look for an IRC edition year here; there is not one. The City has adopted that code by ordinance: Fond du Lac municipal code section 255-2A(1)(a) provides that SPS 320 (Administration and Enforcement), SPS 321 (Construction Standards), SPS 322 (Energy Conservation), SPS 323 (Heating, Ventilation and Air Conditioning), SPS 324 (Electrical Standards), SPS 325 (Plumbing), SPS 361 to 365 (Commercial Building Code), SPS 366 (Existing Buildings) and SPS 375 to 379 (Buildings Constructed Prior to 1914) are hereby adopted and incorporated into this article by reference. Section 255-2A(1)(b) makes that a floating adoption rather than a frozen one: any future amendments, revisions, renumberings, or modifications of the Wisconsin Administrative Code incorporated herein are intended to be made part of this article in order to secure uniform statewide regulation of these matters. So the edition in force in Fond du Lac is whatever the state has in force at the time of the work. The adopting subsection was amended by Ordinance No. 2946 on 23 September 1998 and Ordinance No. 3036 on 14 March 2001, and the municipal code as published includes legislation through 25 March 2026. A municipality that exercises jurisdiction adopts the state code in its entirety and may not add requirements within its scope without the Department of Safety and Professional Services' approval. Commercial buildings run on a different chapter set, and Fond du Lac has been delegated to perform commercial plan review only within stated size limits - new buildings under 50,000 cubic feet, additions leaving a total under 50,000 cubic feet, additions of no more than 2,500 square feet with one floor level, an 18 foot maximum roof span and a 12 foot maximum exterior wall height, and alterations of less than 10,000 cubic feet - with all other plans going to the State of Wisconsin.

Is a mid-roof inspection required in Fond du Lac, WI?

No. Fond du Lac publishes its full inspection roster under the heading Required Inspections for work being completed, and it contains no roof-deck, roof-sheathing, tear-off or other mid-roof stage. The listed stages are the water and sewer lateral inspection; building and deck footings; building foundation; building drain tile; under basement floor plumbing; under basement floor vapor barrier; building electric service; the building rough inspections for framing, electrical, HVAC and plumbing; insulation; shower and tub safing on site-built showers and tubs; and the final inspections for occupancy covering framing, electrical, HVAC, insulation, plumbing, engineering final grade and fire protection where applicable. A reroof pulled under a Fond du Lac building permit is therefore inspected at the end rather than at an interim point during the work. The applicant who signed the permit is the one responsible for calling the inspection in.
