Adopted code
Leadville adopts the 2018 I-Codes by reference and, critically for roofing, adopts the IRC as a separate residential code alongside the IBC. Leadville Municipal Code Sec. 15.04.010 (Codes adopted) states, verbatim, at (a): "The International Building Code (IBC), 2018 Edition, as published by the International Code Council, Inc., ... is hereby adopted by reference as the City of Leadville Building Code as if fully set out in this section with the additions, deletions, insertions, and changes as set forth in Section 15.04.020 of this code." And at (b): "The International Residential Code (IRC), 2018 Edition, as published by the International Code Council, Inc, ... is hereby adopted by reference as the City of Leadville Residential Building Code ("IRC") as if fully set out in this section with the additions, deletions, insertions, and changes as set forth in Section 15.04.030 of this code." The IRC is therefore the operative code for one- and two-family dwelling roofing in Leadville, and Sec. 15.04.030 carries the City's substantial residential amendments - including a replaced Table R301.2(1) and rewritten ice-barrier provisions across IRC Sections R905.2.7 through R905.8.3.1 (see wind_design_criteria, ice_water_shield_required and drip_edge_required). Sec. 15.04.020(3) also adds an IBC Section 101.2.3 (Preemption) providing that "Whenever State law or State regulation imposes higher standards than are required by this code, the State law or State regulation providing the higher standard shall govern." The City's Building Department page separately notes that the City of Leadville and Lake County have both adopted the 2018 International Building Code; the codified Chapter 15.04 above is the authoritative and more complete statement, and is what this record relies on. (Ord. No. 2022-7, § 2, 9-6-22)
Drip edge
Required — Not separately amended by the City of Leadville. Municode § 15.04.030, the full 2018 IRC amendments list (54 numbered items, R101.1 through the E3703 EV-charging addition), was read in its entirety and does not delete or modify R905.2.8.5, so the base 2018 IRC drip-edge requirement stands as adopted code. About drip edge
Ice & water shield
Required — Leadville's printed Table R301.2(1) (§ 15.04.030(19)) carries "Ice Barrier Underlayment Required: Yes." Separately, § 15.04.030 items (35)-(41) amend IRC Sections R905.2.7, R905.3.3, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1, and R905.8.3.1 (the material-specific ice-barrier clauses) in identical, universally-applicable language: "In lieu of normal underlayment, an ice barrier that consists of at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet, shall extend from the edge of the eave to a point at least seventy-two (72) inches inside the interior wall line of the building. All valleys shall have at least one (1) thirty-six (36) inch-wide layer applied and shall extend eighteen (18) inches from centerline each way." About ice & water barrier
Impact-resistant roofing
Not required — Leadville Municipal Code § 15.04.030, the full 54-item 2018 IRC amendments list, was read in its entirety and contains no UL 2218, Class 4, or impact-resistance provision anywhere.
Wind design criteria
Leadville Municipal Code § 15.04.030(19) repeals and replaces Table R301.2(1) of the 2018 IRC with a printed table reading: Ground Snow Load "R301.2.3" (footnoted, per item (20)'s companion amendment to R301.2.3: "Snow load values shall be determined by the data in Appendix E"); Wind Speed 115 mph; Topographic effects No; Special wind region No; Windborne debris zone No; Seismic Design Category C; Weathering Severe; Frost line depth 48"; Termite No; Winter Design Temp -15 degrees F; Ice Barrier Underlayment Required Yes; Flood Hazards "9/15/97" and "3/1/06"; Air Freezing Index 3000; Mean Annual Temp 32 degrees F. (Ord. No. 2022-7, § 2, 9-6-22)
Sales & use tax
7.4% combined (state 2.9% + Lake County 4% + City of Leadville 0.5%; no RTD/SCFD/RTA district). Leadville Municipal Code § 3.40.040 (Citywide Sales Tax) states: "There is hereby imposed and there shall be collected a tax on all sales of tangible personal property and services described in this chapter... The sales tax shall be set at a rate one-half percent of the amount of each sale" (Ord. No. 2024-8, § 3, 10-15-24, passed at election of 11-5-24). Leadville does not appear in Colorado Department of Revenue form DR 1002 (rev. 06/19/19) under either the state-collected-city or the self-collecting-home-rule-city tables, so the city-portion figure is sourced to the Municipal Code itself rather than DR 1002; the Lake County component (4%) is per DR 1002. Re-verified 2026-08-27 against the January 2026 edition of Colorado Department of Revenue form DR 1002, read from a rendered image of its tables rather than from extracted text: the state, county and city figures above match that edition exactly. Where the text above names the June 19, 2019 revision of DR 1002, that describes the edition the figure was originally taken from and is not a current citation.
