Permit process note
Building permits must be posted and visible from the street prior to work beginning. Permits are valid for 180 days, with extensions requiring a written request and justifiable cause. Repair or replacement of less than one square (100 square feet) of shingles does not require a building permit.
Inspection requirements
The permit holder must call for a Final Roof inspection; a mid-roof inspection may also be required depending on the project, per the Building Department. A ladder must be set and secured for all roof inspections prior to the inspection taking place, and the permit card must be available for signing at the time of inspection.
Adopted code
The Town of Wellington's 2021 roofing regulations are based on the 2018 International Residential Code with local amendments, the 2020 National Electrical Code, and the 2018 International Energy Conservation Code.
Drip edge
Required — Not separately amended by the Town of Wellington. Wellington Municipal Code § 18-2-30 (current 2024 IRC amendments, Ord. No. 15-2025, ending cleanly on its own history note) does not delete or modify R905.2.8.5, so the base IRC drip-edge requirement stands as adopted code. The town's own 2021 Roofing Regulations handout corroborates: "*Ice Barrier is required per section R905.1.2. Drip Edge per section R905.2.8.5."
About drip edgeIce & water shield
Required — IRC Table R301.2 as filled in by Wellington Municipal Code § 18-2-30 lists "ICE BARRIER UNDERLAYMENT REQUIRED Yes". Corroborated by the town's older 2021 Roofing Regulations handout: "*Ice Barrier is required per section R905.1.2."
About ice & water barrierImpact-resistant roofing
Not required — Wellington Municipal Code § 18-2-30's current 2024-IRC amendment list was read in full (ending cleanly on its own history note "(Ord. No. 15-2025, § 2, 11-12-25, eff. 1-1-26)") and contains no UL 2218 or Class 4 impact-resistant-shingle mandate.
Wind design criteria
IRC Table R301.2 as filled in by Wellington Municipal Code § 18-2-30 (Amendments to the International Residential Code, current 2024 IRC adoption per Ord. No. 15-2025, eff. 1-1-2026): "GROUND SNOW LOAD * 35 PSF" / "Speed*(MPH) 115 / Topographic effects No / Special wind region Yes / Windborne Debris No" / "SEISMIC DESIGN CATEGORY B". Footnote *: "The design ground snow load pg. shall 35 psf for the Town of Wellington per the Colorado Design Snow Loads, published by the Structural Engineers Association of Colorado (dated April 2016.)" The town's older 2021 Roofing Regulations handout (2018-IRC edition, superseded by the current 2024 IRC adoption) had printed a 30 psf / 115 mph table; the current codified 2024 IRC table above governs.
Roof layer limit / recover
The Town's Residential Re-roofing handout ("2021 Roofing Regulations"): "Roof Replacement: Roof replacement shall include the removal of existing layers of roof coverings down to the roof deck R908.3 Exception: Existing Ice barrier to remain in place with addition of an additional new layer. Maximum two layers of asphalt roof covering." The same handout's FAQ page restates: "How many layers of roofing are allowed? No more than two (2) layers are allowed upon completion of installation." Wellington Municipal Code § 18-2-30's current, exhaustive 2024-IRC amendment list does not separately amend R908, so this practice guidance is not contradicted by the current code.
Sales & use tax
6.95% combined (state 2.9% + Larimer County 1.05% + Town of Wellington 3%). The Town's 3% use tax applies to Motor Vehicles and Building Materials specifically, the roofing-relevant figure. 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.
