The Town of Oak Creek's own website (townofoakcreek.colorado.gov) has no Building Department page of its own; its "Resources" navigation menu links out to "Routt County Building Dept." The Routt County Regional Building Department's Town of Oak Creek page states: "Routt County Regional Building Department provides Building Department services for the Town of Oak Creek Colorado for all Residential and Commercial Buildings and Structures," and lists a "Town of Oak Creek Building Code Ordinance ICC 2021 Editions" and a "Town of Oak Creek Permit Application Plan Review Processes and Time-Frames" document among its linked forms. All permit applications for Oak Creek go through the county's process (CityView portal, per Routt County's building services description), with plan review and inspections performed by county staff. A "Roofing Permit- Required Inspection and Fee Policy" document and a "Residential Commercial Building Roofing and Window Door Replacement Permit Fee Policy" are both published on the county Building Codes & Policies page and list a maximum $300 residential / $500 commercial roof-replacement permit fee plus a $25 plan review fee, indicating roof replacement is permitted work under the county's fee schedule; the full text of those two scanned/image PDFs could not be read to quote exemption language directly, so no definite yes/no roofing-permit answer is stated here. The county's Building Codes & Policies page also references a "Contractor Registration & Certification" section, but no explicit registration criteria applicable to Oak Creek were found on the pages reviewed.

Routt County (which administers building permitting for Oak Creek) states it "adopted the 2021 ICC Series effective January 1, 2024," including the IBC, IRC, IECC, IEBC, IFGC, IPC, IMC, and IPMC, plus portions of the 2021 IWUIC and the Colorado Model State Electric and Solar Ready Code. The county's Town of Oak Creek permitting page separately lists a "Town of Oak Creek Building Code Ordinance ICC 2021 Editions" as a town-specific adopting ordinance.

Required — Required. The Town of Oak Creek amends the climatic and geographic design criteria table and answers "Ice Shield Underlayment Required" with "Yes per IRC Section R905.1.2 Ice Barriers", so the ice barrier provisions of the adopted residential code apply to every roof in town.

Not required — The Town of Oak Creek's Ordinance No. 667, introduced, read, approved and ordered published on October 26, 2023 and effective January 1, 2024, was read in full. It adopts the 2021 editions of the International Building Code with Appendix Chapters C, E and J, the International Residential Code with Appendix Chapters B, C, E, F and Q, the International Existing Building, Mechanical, Energy Conservation, Plumbing, Fuel Gas and Property Maintenance Codes and the International Wildland-Urban Interface Code, together with the National Electrical Code as adopted by the State Electrical Board and the Colorado Model Electric and Solar Ready Code, superseding the codes adopted by Ordinance No. 656. Its amendment schedule was read in full. Of the Wildland-Urban Interface Code the Town adopts only listed sections of Chapter 5, deleting Chapters 3, 4 and 6 and every appendix, and it amends Section 504.2, Roof Assembly, to read that "All Roofs in both residential and commercial buildings for new construction, additions, alterations, repairs, or replacements under permit must have Class A Roofing Materials Installed," excepting historic registered properties where the preservation authorities disallow a fire-retardant-treated or composite wood shake roof. Section 504.2.1 requires valley flashing of not less than 26 gage corrosion-resistant metal over a 36-inch-wide mineral- surfaced cap sheet, and Section 504.10 requires roof, soffit and wall vents to be covered with non-combustible corrosion-resistant mesh against ember penetration. Those are fire classifications and ember-resistance details, independent of impact rating. The Residential Code amendments add an ice barrier at Section R905.1.2. Neither the adopted codes nor any Town amendment requires impact-resistant roof coverings or names a UL 2218 or Class 4 standard. The only statewide instrument reaching reroofing is the Colorado Wildfire Resiliency Code, 8 CCR 1507-39, effective July 1, 2026 in areas designated wildland-urban interface under that code, which requires a Class A roof covering tested to ASTM E108 or UL 790 where 25 percent or more of the roof surface is replaced, at Sections 101.6 and 403.2; that is a fire classification independent of impact rating, and the code sets no impact-resistance requirement.

An ultimate design wind speed of 115 mph with no topographic effects, in Seismic Design Category C for one- and two-family dwellings and townhouses under the residential code. The Town of Oak Creek amends the climatic and geographic design criteria table, which also sets climate zone 7, severe weathering, a frost line depth of 48 inches and a termite hazard of none to slight. Ground snow load is deliberately not a single figure: the table designates the Town a case study area and directs that site-specific ground snow values be taken from the Routt County Regional Building Department, and gives altitude correction factors stepping from 0.77 at 7,000 feet to 0.63 at 12,000 feet.

4.9 percent combined: 2.9 percent state, 1 percent Routt County and 1 percent Town of Oak Creek. The Town is state-collected. Routt County levies a 1 percent use tax that reaches building materials; whether it is deposited at permit issuance rather than remitted afterwards is not established here.
