Inspection Services & Zoning is a City department at Brookfield City Hall, 2000 N. Calhoun Road, open Monday to Friday 7:30 am to 4:00 pm, reachable at 262-796-6646. It publishes its services as building, plumbing, electrical and sign work, permit plan reviews and inspections, and code compliance inspections. INSPECTION IS IN HOUSE, NOT CONTRACTED: the department's own staff directory lists a Zoning & Building Administrator, an Inspection Services Manager, a Plumbing Inspector, an Electrical Inspector, a Code Compliance Inspector, a Building Inspector for commercial work and a Building Inspector for residential work, all as City staff. Re-roofing a one- or two-family house is filed on the City's Residential Building Permit, which the permit page lists as covering re-roofing among the residential improvements for one- or two-dwelling structures; the same page carries a separate Commercial Building Permit that covers re-roofing for commercial, office and industrial buildings and for any multi-family structure of more than two units. Applications moved online effective January 2, 2026 and are filed through the City's OpenGov permitting portal. Municipal Code section 15.04.150 requires the department to use the standard building permit form prescribed by the Department of Safety and Professional Services and to file a copy of every permit issued for a one- or two-family dwelling with that department, as Wis. Stat. 101.65(3) requires. Fees are set in the City of Brookfield Fee Schedule under section 15.04.200; note that section 15.04.440(A) still points at section 15.04.780 for the reroofing fee and that section was repealed in 2025, so the published fee schedule is the live figure. One extra step applies to commercial work only: section 15.04.440(D) requires plan commission approval, or approval by its designee, before applying for a commercial reroofing permit, and Zoning Code section 17.100.020(B) lets the Director of Community Development administratively approve replacing a roof on an existing development.

STATE CODE, ADOPTED BY THE CITY AND EXTENDED TO OLDER HOUSES. One- and two-family dwellings in Brookfield 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. Brookfield Municipal Code section 15.04.050 adopts it in these words: "The Wisconsin Uniform Dwelling Code, SPS 320 through 325, inclusive, and all amendments thereto (the UDC) are made a part of this chapter by reference and shall apply to all one- and two-family dwellings, the initial construction of which was commenced on or after the effective date of the UDC, and to additions, alterations, repairs and maintenance of such dwellings, whether initially constructed before or after the effective date of the UDC." Section 15.04.070(B) says the same thing from the other side: "the UDC shall apply to dwellings which would have been subject to the UDC by its terms but for the fact that construction of such dwelling was commenced prior to the effective date of the UDC." Read section 15.04.050 together with that savings clause and not against the definitions section, where "Dwelling" is defined as a building "the initial construction of which is commenced on or after the effective date of the UDC" - the two operative sections are what extend the code to an older house. That matters more than it looks, because the state code by its own terms stops at dwellings begun before June 1, 1980 and at alterations to them unless the municipality adopts chs. SPS 320 to 325 for that purpose, and Brookfield has done exactly that. Commercial buildings, and three-family and larger buildings, run on a different code set: section 15.04.060 adopts the Wisconsin Commercial Building Code, SPS 360 to 366. That is a separate track and is not the subject of the residential fields recorded here. Chapter 15.04 of the Municipal Code was read in full and the only roof-assembly requirement the City writes for itself is the two-layer rule at section 15.04.440.

Not required — No drip edge is required by code on a Brookfield 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 chimney cap rule, which is not a roof edge requirement. On the City side, the whole Brookfield Municipal Code was read, all seventeen titles, and it contains no drip edge requirement; the only roofing provisions the City writes for itself are the permit and two-layer rules at section 15.04.440. Brookfield could not add one for a one- or two-family dwelling in any event, because Wisconsin bars a municipality from enforcing a dwelling ordinance that does not conform to the state code. 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.

Required — 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) requires ice dam protection 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 in 12 or less. It must be sheet metal or a product labelled as meeting ASTM D1970, and it must 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 Brookfield 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. Brookfield adds nothing to this: the Brookfield Municipal Code was read and carries no ice barrier or ice dam provision anywhere. 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. On the age half of that, Brookfield has acted: Municipal Code section 15.04.050 applies chs. SPS 320 to 325 to additions, alterations, repairs and maintenance of one- and two-family dwellings "whether initially constructed before or after the effective date of the UDC," and section 15.04.070(B) repeats that the code reaches dwellings that would have been subject to it but for having been built before its effective date. So an older Brookfield house is not outside the state code. About ice & water barrier

Not required — No mid-roof or roof-deck inspection stage is set by the City. Municipal Code section 15.04.280(C) lists the progress inspections a building permit holder must call for, and they are: location against the approved plot plan; footings and foundation walls; framing, after all framing and mechanicals are in place and before the work is covered; subgrade, drain tile and forms before the basement floor is poured; plumbing; electrical; a final inspection on completion and before occupancy; and a fire department inspection where required. No roof, roof-deck, tear-off or in-progress roofing stage appears anywhere in that list. Two qualifications a roofer should still price in. Section 15.04.270(A) lets the director inspect permitted work "with or without notice or invitation, from time to time and at any time" at intervals the director judges sufficient, so an inspector may appear mid-job even though no mid-roof stage is scheduled. And section 15.04.270(B) provides that where a required inspection cannot be made because the work has been covered or concealed, the permit holder must uncover it as directed - which is what bites if deck repair or framing work on a reroof is closed up before it is seen. Ask Inspection Services which stages a particular permit will carry rather than assuming the reroof is inspected only at the end.

Not required — No impact-resistance or hail-rating mandate applies in Brookfield. The statewide Wisconsin uniform dwelling code contains no UL 2218 requirement, no Class 4 or Class IV impact rating and no FM 4473 reference anywhere in the chapters that govern one- and two-family dwellings, including the roof coverings section; its catch-all for coverings not otherwise addressed sends the installer to the manufacturer instructions or a national standard recognised by the department, which sets no impact class. On the City side, the whole Brookfield Municipal Code was read and no UL 2218, Class 4 or FM 4473 requirement appears in it; the City reroofing ordinance at section 15.04.440 addresses the permit and the layer count only. Impact-resistant shingles are an insurer-driven upgrade in this market, not a code obligation. One caution for reading paperwork on a Brookfield job: a Class A, B or C designation, or a reference to ASTM E108 or UL 790, is a FIRE rating and says nothing about hail, and ASTM D3161 or D7158 is a WIND rating. Only UL 2218 or FM 4473 answers impact.

NO DOLLAR THRESHOLD AND NO SQUARE-FOOTAGE THRESHOLD - a reroof takes a permit and a flat fee. The City's Residential Building Permit Fees schedule, dated as of January 1, 2026, carries the line "Permit Fee - Re-Roofing" at 80 dollars per permit, with the minimum and maximum amount columns blank, so the fee does not band by valuation. The only no-permit-below-this-size line anywhere on that schedule is for accessory structures under 30 square feet, and there is no equivalent for roofing. On the code side, Municipal Code section 15.04.440(A) requires a permit before anyone may "construct, install or replace a roof covering on top of any existing roof covering of any dwelling, or other building or structure," and the general building permit requirement at section 15.04.280(A) reaches anyone who improves, alters, converts or extends a building. Three further provisions decide how much of the roof has to be brought up to code, and they are the ones a partial repair runs into. Section 15.04.070(B)(3) provides that "If more than twenty-five (25) percent of the roof covering of a dwelling or other building or structure is replaced in any twelve (12) month period, then all such roof covering shall comply with the provisions of this chapter and the other applicable legal requirements" - so patching past a quarter of the roof in a year pulls the whole roof covering into compliance, and the twelve-month window means two small repairs can add up to it. Section 15.04.070(B)(1) pulls an entire building into compliance where the cost of alterations or repairs over the life of the building exceeds fifty percent of its assessed value. And section 15.04.280(D) lets the director waive requirements where the permit is for minor alterations or repairs sufficiently described in the application, which is a discretionary relaxation and not a standing exemption. Confirm scope with Inspection Services at 262-796-6646 before treating a particular job as exempt.

STATE-SET, AND EXPRESSED AS A PRESSURE RATHER THAN A DESIGN WIND SPEED IN MILES PER HOUR. Wis. Admin. Code SPS 321.02(1)(c) provides that dwellings "shall be designed and constructed to withstand either a horizontal and uplift pressure of 20 pounds per square foot acting over the surface area or the wind loads determined in accordance with ASCE 7-05, Minimum Design Loads for Buildings and Other Structures," with a published note that ASCE 7-05 allows for substantial reduction from the 20 pounds per square foot figure. The general load rule at SPS 321.02(1) requires a complete load path capable of transferring all loads from point of origin through the load-resisting elements to the foundation, and SPS 321.02(3)(h) requires all building components to be fastened to withstand the dead load, live load, snow load and wind load. Snow is the one input that varies geographically: SPS 321.02(1)(b)2. provides that roofs "shall be designed and constructed to support the minimum snow loads listed on the zone map," which is Figure 321.02, a statewide zone map, so a Brookfield ground snow figure is read off that map rather than stated as a single statewide number. IMPORTANT for anyone used to International Residential Code jurisdictions: because Wisconsin works in pounds per square foot and a zone map, there is no ultimate design wind speed in miles per hour for Brookfield, and the 20 pounds per square foot figure must not be converted into one. Brookfield adds nothing of its own - the Brookfield Municipal Code was read and its only uses of the word wind are the wind energy system provisions at section 15.04.435, which are about turbines and not about roof loading.

TWO SETS OF RULES APPLY IN BROOKFIELD AND A ROOFER SHOULD KNOW BOTH. The City has its own reroofing ordinance. Brookfield Municipal Code section 15.04.440(B), headed "Limit on Layers," reads in full: "No more than two layers of roof covering shall be permitted on any dwelling or other building or structure unless the director approves additional layers." On top of that, 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 more 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 permanent roof covering. So at most two total layers, and less than that where the deck is wet or deteriorated or the existing roof is one of the listed materials. The two extra state conditions are not repeated in the City ordinance, and the City ordinance contemplates the director approving additional layers while the state rule contains no such route; both are published here as they are written and neither is chosen over the other, so ask Inspection Services which it will apply before quoting a third layer. A complete tear-off to the deck is not restricted by either rule. 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. On the age half of that, Brookfield has acted, which sets it apart from most Wisconsin municipalities: Municipal Code section 15.04.050 applies chs. SPS 320 to 325 to additions, alterations, repairs and maintenance of one- and two-family dwellings "whether initially constructed before or after the effective date of the UDC," so the age of the house does not put a Brookfield job outside the state code. The City ordinance goes further than the state code's own opt-in note, which speaks only of additions and alterations, by naming repairs and maintenance as well; this record states the City text and the state text as each is written and does not decide how they fit together. The City reroofing ordinance at section 15.04.440 carries no age limit of its own either.

STATE-SET. Brookfield adds nothing of its own - the entire Brookfield Municipal Code was read and it contains no roof sheathing, decking or nailing provision - so the Wisconsin uniform dwelling code governs. Wis. Admin. Code SPS 321.27(9) sets the deck standard for one- and two-family dwellings in three parts. For structural sheathing, "The allowable loads and spans for structural sheathing shall be in accordance with the grade stamp on the panel." For roof boards, where the rafter spacing is 24 inches on center or less, "roof boards may be used that have a minimum thickness of 5/8-inch for solid sheathing and 3/4-inch for spaced sheathing," and where the rafter spacing is greater than 24 inches on center, "roof boards shall be tongue and groove, at least 1.5 inches thick." For roof planks, they "shall be tongue and groove or splined and at least 2 inches, nominal, in thickness," shall "terminate over beams unless the joints are end matched," shall be "laid so that no continuous line of joints will occur except at points of support," and "shall be nailed or fastened to each beam." Wisconsin expresses this as a panel grade-stamp and board-thickness rule keyed to rafter spacing rather than the International Residential Code formulation used in IRC states, so do not carry an IRC sheathing specification onto a Brookfield job. One local point: replacing deck is a structural alteration, and Municipal Code section 15.04.070(C) pulls an entire building into compliance where repairs touch nonconforming construction of structural members of roofs, beams or girders.

5.0% on materials - the Wisconsin state sales and use tax of 5% and nothing else. WAUKESHA COUNTY IMPOSES NO COUNTY SALES AND USE TAX, which makes Brookfield one of the places where the familiar 5.5% Wisconsin figure is wrong: the Department of Revenue sales tax rate chart lists Waukesha, county code 67, with a 5% state rate and an empty county tax column. The City of Brookfield lies in Waukesha County and imposes no municipal sales tax; the Department of Revenue states that "The city of Milwaukee is the only municipality that imposes a city sales and use tax," and no premier resort area tax applies here. How the tax actually falls on a roofing job matters more than the rate. Wisconsin treats a roof as real property - the Department of Revenue contractor guidance answers it by name, listing roofs as real property for residential installation, residential repair, commercial installation and commercial repair alike - so the roofing contractor is the consumer of what it installs. The contractor pays sales or use tax when buying shingles, underlayment and other materials, and "is not permitted to collect sales tax from its customers on its sales price from sales of real property construction activities," meaning neither labour nor materials are taxed on the reroofing contract. The exception runs the other way: selling lumber, roofing materials or other tangible personal property WITHOUT installation is a retail sale and is taxable. So the rate is a cost input on the material purchase rather than a line on the homeowner invoice.
