Inspection requirements
A final inspection is required after a re-roof permit is issued to verify compliance with the building code.
Adopted code
Lee's Summit adopted the 2018 International Building Code, 2018 International Residential Code, 2018 International Plumbing Code, 2018 International Mechanical Code, 2018 International Fuel Gas Code, 2018 International Fire Code, 2017 National Electrical Code, and ICC/ANSI A117.1-2009, effective January 8, 2019. The city states it is in the process of adopting the 2024 Codes, tentatively effective by mid-summer 2026.
Drip edge
Required — Drip edge is required at eaves and rake edges of shingle roofs (IRC R905.2.8.5). The jurisdiction adopted the 2018 International Residential Code via Ordinance No. 8584, § 1 (3-19-2019, eff. 4-1-2019; Article IX, Secs. 7-900 through 7-945); that instrument, read in full, does not amend R905.2.8.5, so the code's drip-edge requirement stands as enacted local law. About drip edge
Ice & water shield
Required — The city's own Table R301.2(1) data entry, codified in Sec. 7-902 of the Lee's Summit Building Code (Ord. No. 8584, § 1, adopted 3-19-2019, effective 4-1-2019), lists "Ice Barrier Underlayment Requirement ... Yes." Section R905.1.2 (Ice barriers), which supplies the trigger language for that "Yes" -- "an ice barrier ... shall be installed ... and shall extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building" -- is adopted as part of the 2018 IRC (Sec. 7-900) and is not amended or altered anywhere in Article IX. About ice & water barrier
Mid-roof inspection
Not required — The code's Required Inspections list (Sec. 7-160, subsections A-K) names footing/foundation, suspended-slab/under-floor, elevation-survey, framing (new construction only, when "the roof deck or sheathing, all framing ... are in place"), lath/gypsum, fire-resistant-penetration, special, fire-protection, final, and reinspection -- no distinct mid-roof, deck, or dry-in inspection stage is listed for re-roof work. The city's residential permits page states re-roof permits require only that "A final inspection is required after a re-roof permit is issued to verify compliance with the building code."
Impact-resistant roofing
Not required — As of July 2026 the City of Lee's Summit's own Building Codes and Amendments page still carries the notice "The City of Lee's Summit is in the process of adopting the 2024 Codes, which will tentatively go into effect by mid-summer 2026," and the codes shown as adopted remain the 2018 International Building Code and 2018 International Residential Code (Ordinance #8536, building; #8537, fire; council action January 8, 2019); the 2024 codes have not yet landed. The operative local amendment instrument is Chapter 7 of the Code of Ordinances, "Lee's Summit Building Code" (Ord. No. 8584, § 1, adopted 3-19-2019, effective 4-1-2019), read in full across Articles I through XIV (Sec. 7-100 through 7-1412). Article IX, "Residential Code" (Sec. 7-900 through 7-945), adopts the 2018 IRC and amends only three IRC Chapter 9 (Roof Assemblies) items: Sec. 7-922 (Section R801.3, roof drainage), Sec. 7-923 (Section R902.1, roof covering materials -- a fire classification amendment requiring a Class C minimum roof covering tested to UL 790 or ASTM E 108, with Class A, B, or C required near property lines), and Sec. 7-924 (Section R908.1, re-roofing/repair threshold). No other IRC Chapter 9 section is touched, and none of these three items addresses impact resistance. Article II, "Building Code" (Sec. 7-200 through 7-229), separately amends the 2018 IBC's commercial roof-covering provisions at Table 1505.1, Section 1505.5 (non-classified roofing), and Section 1511.1 (reroofing), all of which are likewise fire-classification or repair-threshold rules. No UL 2218, Class 4, or impact-resistance provision appears anywhere in the instrument.
Repair permit threshold
"Re-roofing includes any repairs of more than 10% of the total roof covering in any three year period. A repair of 10% or less of the total roof covering in any three year period may utilize approved roofing materials comparable to the existing roofing materials." (Sec. 7-924, amending IRC Section R908.1; parallel language at Sec. 7-226, amending IBC Section 1511.1, and Sec. 7-225, amending IBC Section 1505.5, which caps non-classified-material repairs at "ten (10) percent or less of the total roof covering in any three-year period.")
Wind design criteria
90 mph wind design speed, topographic effects No, special wind region No, windborne debris zone No (Sec. 7-902, "International Residential Code Data Entry; Table R301.2(1)," Ord. No. 8584, § 1, adopted 3-19-2019, effective 4-1-2019, amending the 2018 IRC): "Wind Design Speed (mph): Ninety (90) miles per hour. Topographic effects: No. Special wind region: No. Windborne debris zone: No."
Sales & use tax
Lee's Summit spans two counties, and the Missouri DOR publishes two different base combined rates for it. The Cass County portion has a base combined rate of 8.6000% (jurisdiction code 41330-037-000, no zoo district tax). The Jackson County portion has a base combined rate of 8.4750% (jurisdiction code 41330-095-000, includes the Kansas City Metropolitan Zoological District tax) -- lower than the Cass County portion despite the added zoo tax, because the underlying county tax differs; a roofer should confirm which county a given Lee's Summit address sits in. Within the Jackson County portion, more than a dozen stacked CIDs and TDDs push the combined rate higher on specific parcels, e.g. Summit Fair CID and the Downtown Lee's Summit CID (41330-095-012, -014) both raise it to 9.4750%. Source: DOR statewide Sales/Use Tax Rate Table for July 2026. Missouri's own Contractors Tax Matrix (DOR Audit Services, Industry Guidance, eff. 10-24-2022, https://dor.mo.gov/taxation/business/documents/Contractors_000.pdf) treats a roofing contractor as the final consumer of materials incorporated into real property: "Contractor sales of tangible personal property where title passed to the customer after installation" is listed Exempt, while "Tangible personal property to be sold as an attachment to real property" is listed Taxable -- meaning the contractor owes sales/use tax on shingles, underlayment, etc. at the point of purchase from the supplier, and does not separately charge the homeowner sales tax on the installed roof or on labor. Lee's Summit does not collect a construction use tax at building-permit issuance (the Colorado home-rule pattern does not apply here); the DOR's own Sales/Use Tax page (https://dor.mo.gov/taxation/business/tax-types/sales-use/) describes local use tax as a self-reported obligation -- "Use tax is imposed directly upon the person that stores, uses, or consumes tangible personal property in Missouri," with "a purchaser ... required to file a use tax return if the cumulative purchases subject to use tax exceed two thousand dollars in a calendar year" -- not a sum collected at the permit counter.
