Adopted code

Town of Ridgway - Building Department

Yes, a permit is required to replace a roof in Ridgway, CO, issued by Town of Ridgway - Building Department. The Town's Building Department page states: "The Building Official is responsible for building permit review, inspections and code enforcement. The Town of Ridgway has adopted the 2018 International Codes, as amended in RMC 6-1. Please call the building office to confirm permit requirements before starting any work. All plumbing and electrical permits are handled by the State of Colorado." The town's 2018 IRC amendments (Ridgway Municipal Code Section 6-1-1, Section R105.2 "Work exempt from [building] permit") add: "11. Re-roofing less than 200 square feet. 12. Re-siding with similar materials less than 200 square feet," meaning re-roofing at or above 200 square feet requires a building permit under the town's own code language; roofing_permit_ required is set true on that basis for typical whole-roof jobs. The same amendments require a $75 town site permit for the enlarged 150-sq-ft accessory-structure exemption, a $75 site permit for exempt fences under 6 feet, and a $75 site permit for exempt low decks, and state permit fees generally follow Appendix L of the 2018 IRC (plan review fees at 65% of the building permit fee). Work must commence within 180 days of permit issuance. A Building Permit Application & Applicant Checklist, Demolition, Encroachment, Fire Suppression Tap, Flood Plain Development, Sign, Site, Stove, and Water & Sewer Tap applications are published on the Building Department page; there is no separate re-roofing-specific application form. No wildfire/ignition-resistant or "Class A" roofing material requirement was found in RMC Chapter 6, Section 1.

Registration details
  • license: Ridgway Municipal Code Chapter 8 - Licensing was read in full and contains only license/permit regimes for manufactured/travel home parks (Section 1), outdoor concerts (Section 2), transient merchants (Section 3), marijuana (Section 4), and short-term rentals (Section 5) — no general business license or contractor-registration provision. The Town's own Administrative Information and Forms page lists only "State Sales Tax & Business License Links" (Colorado Business Express and Colorado.gov/RevenueOnline) under that heading, pointing applicants to state-level resources rather than a town license. RMC Section 3-2-3 requires a Sales Tax License for any retailer "engaging in the business of selling at retail," a tax-administration license distinct from a contractor registration.
Permit process note

Inspection requirements
"A Certificate of Occupancy (CO) must be obtained before any building can be occupied."

All plumbing and electrical permits/inspections are handled by the State of Colorado, not the town.
Adopted code
Ridgway Municipal Code Section 6-1-1(A)-(B) (amended by Ord. 9-2019): "There is hereby adopted... The International Building Code, 2018 Edition, including Appendices E, I and J... There is hereby adopted... The International Residential Code, 2018 Edition, including Appendices E, F, G, H, J, L, M, Q, R and S..." both as published by the International Code Council, with local amendments to sections including 101.4.3 (Plumbing, per the state-adopted IPC), 101.4.8 (Electrical, per the state-adopted Electrical Code), 104.10.1 (Flood Hazard Areas per RMC 6-2), 105.2/R105.2 (work exempt from permit, described above), 107.1 (architectural/structural documents must be prepared by a Colorado-licensed architect/engineer), and 109.2 (permit fees per Appendix L of the 2018 IRC).
Drip edge
Required — Not separately amended by the Town of Ridgway. Municode § 6-1-3(A), the full IRC amendments list (numbered items covering Sections R101 through the definitions article), 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 — Ridgway Municipal Code § 6-1-3(A)(12)'s Table R301.2(1) amendment prints "Ice Barrier Underlayment Required: Yes" as an added row alongside the town's other climatic design values. About ice & water barrier
Impact-resistant roofing
Not required — Ridgway Municipal Code § 6-1-3(A), the full IRC/IBC amendments list, was read in its entirety and contains no UL 2218, Class 4, or impact-resistance provision anywhere.
Wind design criteria
Ridgway Municipal Code § 6-1-3(A)(12) amends Table R301.2(1) Climatic and Geographic Design Criteria of the 2018 IRC: "The following values shall be added to the table: Ground Snow Load: 65 lbs/Sq. Ft. Wind Speed: 115 Ultimate/Exposure C. Topographic Effects: No. Special Wind Region: No. Windborne debris zone: No. Seismic Design Category: C. Weathering: Severe. Frost Line Depth: 36 inches. Termite: Slight. Winter Design Temperature: 0 degrees F. Ice Barrier Underlayment Required: Yes. Flood Hazards: Ridgway Municipal Code Subsection 6-2-6. Air Freezing Index: 2000. Mean Annual Temperature: 43 degrees F."
Roof layer limit / recover
Ridgway Municipal Code § 6-1-3(A)(19) amends IRC Section R908.3.1.1 "Roof recover not allowed," item #3, to read: "Where the existing roof has two or more applications of any type of roof covering unless the third covering is metal panels and appropriate length fasteners are used" — i.e. a maximum of two existing roof-covering layers before a recover is disallowed and tear-off is required, with an exception permitting a third layer specifically for metal panel roofing installed with appropriate length fasteners.
Sales & use tax
9.05% combined (state 2.9% + Ouray County 2.55% + Town of Ridgway 3.6%; no RTD/SCFD/RTA district — Ouray County is outside the San Miguel Authority for Regional Transportation boundary). Ridgway is a home-rule municipality and self-collects its own sales tax; Ridgway Municipal Code § 3-2-4(B)(1) states: "There is imposed upon all sales of commodities and services specified in Subsection 3-2-4 a tax at the rate of 3.6 percent of the amount of the sale." The Ouray County component is per Colorado Department of Revenue form DR 1002 (rev. 06/19/19; updated semi-annually), which separately lists Ridgway's own rate informationally as 3.60%, consistent with the town's own code. 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.
