Roofing Permit (Re-Roof) in Aspen, Colorado

Required for all re-roofing projects in Aspen (patching less than one square, 10'x10', does not require a permit). Governed by the Roof Assembly sections of the currently adopted codes; roof work involving changes to height, slope, footprint, structural framing, or insulation requires a full building permit instead of a roofing permit. Ground snow load design criterion is 100 psf.

When you need this permit

  • All re-roofing projects require a Roofing Permit; roof work changing height, slope, footprint, structural framing, or cavity insulation requires a Building Permit instead
  • Patching less than 1 square (10 ft x 10 ft) does not require any permit
  • UL or ICC-ES report required for the listed Class A roof assembly specific to the roofing product and installation (per Ordinance 1, 2023)
  • Ground snow load of 100 psf: if adding insulation above the roof deck and the building was not constructed to this snow load, a Letter of Structural Integrity from a Structural Engineer is required
  • If insulation is present above the roof deck, required minimum values are R-40 above deck (Commercial) or R-49 above deck (Residential), or an alternate design approved by the Building Department for justified infeasibility
  • Snowguards/stops required on roofs that shed onto neighboring properties or occupied areas (walkways, stairways, alleys, decks, pedestrian/vehicular exits, or areas above gas/electric utility meters)
  • If heat tape is installed (new or existing) exceeding 1,000 watts, REMP fees apply, and a sub-electrical permit is required for any roof with heat tape
  • If the address is on the City's Inventory of Historic Sites and Structures or within a Historic District, HPC Approval is required before the roofing permit
  • Two photographs of existing conditions required (one showing the overall structure, one close-up of the existing roof)
  • An asbestos test is NOT required if all materials to be removed are asphaltic/tar-impregnated/non-friable, removed by hand (no circular saws), and disposed of rather than recycled — all three conditions must be met

Tips

  • Aspen's 100 psf ground snow load is a serious design constraint for re-roofs adding insulation — if your building wasn't built to that load, you need a Structural Engineer's Letter of Structural Integrity before proceeding.
  • Check the three asbestos-exemption conditions carefully (asphaltic/non-friable materials, hand removal only, disposal not recycling) — if you can't satisfy all three, a full asbestos test is required, adding time and cost.
  • Any roof with heat tape needs a sub-electrical permit in addition to the roofing permit, and heat tape over 1,000 watts triggers REMP fees and control requirements (automatic shutoff above 40°F plus a moisture/daylight sensor or timer).

Aspen, Colorado has adopted: 2021 International Building Code (IBC) — adopted by Ordinance #1, 2023 (January 24, 2023), effective for permits submitted March 31, 2023 and later; the IRC has NOT been adopted by the City of Aspen and is not applied — single-family, duplex, and townhouse projects are reviewed under the 2021 IBC as locally amended, per the City's own 'Building Permit Application Checklist for Singlefamily, Duplex, and Townhouse Projects (2021 IBC)'; 2021 International Existing Building Code (IEBC); 2021 International Mechanical Code (IMC); 2021 International Fuel Gas Code (IFGC); 2021 International Plumbing Code (IPC); 2021 International Fire Code (IFC); 2021 International Swimming Pool and Spa Code (ISPSC); 2021 Aspen Energy Code (local amendment/supplement to the IECC); 2023 National Electrical Code (NEC), effective August 1, 2023; 2024 Colorado Wildfire Resiliency Code with local amendments — adopted by Ordinance 6, 2026 (March 25, 2026), effective April 23, 2026; referenced directly in the current Fence Permit Application Checklist (fences within 8 feet of a structure must be noncombustible/ignition-resistant; hedges within 5 feet must use ignition-resistant vegetation); Prior code cycle: 2015-edition IBC/IEBC/IMC/IFGC/IPC/IFC applied to permits submitted between February 2017 and March 2023, with local amendments in Ordinance 40, 2016 (superseded, listed for reference only); Local amendments to all adopted codes are codified in Title 8 (Building and Building Regulations) of the Aspen Municipal Code; Municode's Aspen library is a JavaScript-rendered application that could not be scraped directly in this or the prior session (confirmed again 2026-07-23: raw curl returns only the Angular SPA shell, and the shared browser environment used for the re-chase attempt this session was too unstable to reliably render deep-linked Title pages). However, the City's own 'Currently Adopted Building & Energy Codes' page (aspen.gov/197) directly publishes a 'Climate & Geographical Design Criteria' table (2026-07-23, live-confirmed): Ground snow load 100 psf; Wind Speed/Exposure Category 89 mph / B; Seismic Design Category C; Weathering Severe; Frost line depth 36 inches; Termite None to slight; Decay None to slight; Winter design temp -15°F; Summer design temp 82°F; Ice shield underlayment required Yes; Air Freezing Index 2000; Mean annual temperature 40°F. This resolves the design-criteria gap without needing Title 8/Municode.. Local amendments apply — see the Aspen overview page for the full list.

100 psf, per the City's published Roof/Re-Roof Application Checklist. If a re-roof adds insulation and the building was not originally constructed to this snow load, a Structural Engineer's Letter of Structural Integrity is required.
