  • license: The City of Topeka maintains and publishes a list of contractors licensed under a distinct "Roofing Contractors" specialty category (alongside categories such as Demolition, Fire Alarm, Fire Sprinkler, and Swimming Pool Contractors), separate from its general contractor license list.
Permit process note
Construction permitting begins at the Building Permit office on the 3rd floor of the Holliday Building, where "plans and/or specifications of the proposed project must be submitted." Residential exterior alteration work, including roof-mounted solar panels, is processed through the city's online application portal under a "Residential Exterior Alteration" project type. By city ordinance (Topeka Municipal Code Chapter 14, Section 10.020), an owner-occupant may pull a homeowner's permit to perform work themselves on their own residence; otherwise work must be done by a licensed contractor in that trade. The city's permit guidance does not list roofing among its examples of repair or replacement work exempt from a permit, and does not state a roofing-specific permit rule either way.
Adopted code
2021 International Residential Code (IRC), Chapters 1 through 10 and Appendix F, plus the 2009 International Energy Conservation Code (IECC) for new residential construction, both with local amendments per the Topeka Municipal Code (TMC). Commercial construction is under the 2021 International Building Code (IBC), 2021 International Existing Building Code (IEBC), and 2021 IECC (building envelope only), also with local amendments.
Drip edge
Required — Drip edge is required at eaves and rake edges of shingle roofs (IRC R905.2.8.5). The jurisdiction adopted the 2021 International Residential Code via Ordinance No. 20467 (12-5-2023, TMC 14.55.010); that instrument, read in full, does not amend R905.2.8.5, so the code's drip-edge requirement stands as enacted local law. Notably, the same ordinance (§ 34) REPEALED the city's prior local drip-edge amendment (TMC 14.55.610), deliberately returning to the unamended IRC text. About drip edge
Ice & water shield
Not required — IRC Table R301.2(1) as substituted by the City of Topeka lists "NO" in the "Ice Barrier Underlayment Required" column. Footnote h to the table states: "In accordance with Sections R905.2.7.1, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'YES.' Otherwise, the jurisdiction shall fill in this part of the table with 'NO.'" (Topeka Municipal Code 14.55.230, IRC Table R301.2(1), enacted by Ord. 20467 § 9, 12-5-23.) About ice & water barrier
Impact-resistant roofing
Not required — Ordinance No. 20467 of the City of Topeka, Kansas (passed and approved by the Governing Body December 5, 2023; published in the Topeka Metro News December 11, 2023), "concerning adoption of the 2021 International Residential Code, amending and repealing several sections of Chapter 14.55 of the Topeka Municipal Code," was read in full: 39 sections, amending or repealing TMC 14.55.010 through 14.55.640. Section 1 (TMC 14.55.010) adopts the 2021 IRC, Chapters 1 through 10 (which includes Chapter 9, Roof Assemblies) and Appendix AF (Radon Control Methods), by reference except as amended in Article II. Of the 35 numbered local amendments that follow, only two touch roofing: Section 9 (TMC 14.55.230, substituting Table R301.2(1), whose footnote h cross-references the ice-barrier sections R905.2.7.1 through R905.8.3.1) and Section 34 (TMC 14.55.610, repealing the city's prior local drip-edge amendment so Section R905.2.8.5, Drip edge, reverts to unamended IRC text). No other Chapter 9 section -- R902 Roof Classification, R903, R904, R906, R907, or R908 -- is named or amended anywhere in the ordinance, so Chapter 9 stands as adopted base 2021 IRC text apart from those two items. No UL 2218, Class 4, or impact-resistance provision appears.
Wind design criteria
114 mph ultimate design wind speed (3-second gust), topographic effects No. Wind exposure category is not filled in on the table and is instead determined on a site-specific basis per Section R301.2.1.4. The substituted table contains no separate special wind region or windborne debris zone columns/entries (Table R301.2(1) as substituted in its entirety by TMC 14.55.230, Ord. 20467 § 9, adopted 12-5-23).
Sales & use tax
Topeka's combined sales tax rate is 9.35% (KS state 6.5% + Shawnee County 1.35% + City of Topeka 1.5%). KDOR Pub. 1700 lists 12 special districts, ranging from the Heartland Park STAR Bond (no rate increase, 9.35%) to several CIDs (Cyrus Hotel, Downtown Ramada Inn, South Topeka, Wheatfield Village) at 11.35%. Per Kansas DOR Pub. KS-1525 "Sales & Use Tax for Contractors, Subcontractors, and Repairmen" (Rev. 7-29-25): "Services performed to install or apply tangible personal property are exempt from sales tax when the services involve the original construction, reconstruction, restoration, remodeling, renovation, repair or replacement of a residence" -- so residential re-roof LABOR is exempt, but materials are not: contractors "are considered to be the final user or consumer of the materials they install for others, and must pay Kansas sales or use tax on them" at the time of purchase (or self-assessed compensating use tax on out-of-state materials, via Form CT-10U, per the same publication's Compensating Use Tax section). Commercial re-roof labor is taxable ("roofing, siding and guttering" is listed as a taxable labor service on commercial projects). Pub. KS-1525 describes only two collection points for contractor materials tax -- retailer sale or self-assessed use tax -- with no mechanism tied to building-permit issuance anywhere in the publication; Kansas sales/use tax is administered centrally by KDOR, not self-collected by home-rule cities as in Colorado.
