Town of Columbine Valley Building Department

Yes, a permit is required to replace a roof in Columbine Valley, CO, issued by Town of Columbine Valley Building Department. A building permit is required any time there is an addition, alteration, repair or conversion to a home, and the Town's example list of permit-requiring work explicitly includes reroofing (along with water heater replacement, kitchen remodels, basement finishes, and deck construction). Permits are not required for painting, drain cleaning, new floor coverings, gutters, or other cosmetic improvements. The Building Department publishes three permit application types: a Non-Structural Building Permit (e.g., siding, like-for-like windows, AC/water heater swaps), a Building Permit with Plan Review (structural changes, new homes), and a dedicated Roofing Permit Application for standard roof replacement (asphalt shingles, shake shingles, ceramic tiles); a stamped engineer letter is required if the reroof involves structural modification, and the Building Department may request a Mid-Roof Waiver from the homeowner on some projects. Homeowners may pull their own permits as DIY, but any subcontractor they employ must hold a Town contractor license, and the Town will not issue a permit to a homeowner for work performed by unlicensed contractors. Every building permit application must be accompanied by a copy of the signed contractor-homeowner contract and, for any project altering the building exterior (including roofs and windows), HOA approval. Small projects are typically permitted within a few days; larger projects such as home additions may take up to a week. The building permit fee is based on the estimated value of the work, and Town of Columbine Valley Sales & Use Tax (valuation x 50% x 3%) plus Arapahoe County Open Space Tax (valuation x 50% x 0.25%) are assessed on top of it, with a Plan Review Fee (permit fee x 65%) added when plans require code-compliance review.

Permit process note
A building permit is required any time there is an addition, alteration, repair or conversion to a home, and the Town's example list of permit-requiring work explicitly includes reroofing (along with water heater replacement, kitchen remodels, basement finishes, and deck construction). Permits are not required for painting, drain cleaning, new floor coverings, gutters, or other cosmetic improvements.

Homeowners may pull their own permits as DIY, but any subcontractor they employ must hold a Town contractor license, and the Town will not issue a permit to a homeowner for work performed by unlicensed contractors. Every building permit application must be accompanied by a copy of the signed contractor-homeowner contract and, for any project altering the building exterior (including roofs and windows), HOA approval. Small projects are typically permitted within a few days; larger projects such as home additions may take up to a week.

Inspection requirements
Inspections are performed by the Town's own Building Department, not a delegated county or contract inspector. To request an inspection, call Town Hall at 303-795-1434 between 8 a.m. and noon, Monday through Friday; inspections requested before noon are completed the following business day on a first-come, first-served basis, and the Town can typically accommodate four to six inspections per day. The Building Department recommends a contractor or homeowner be present at the inspection; a failed or incomplete inspection may carry a $45 re-inspection fee. Certificates of Occupancy are issued following final inspection once a structure is complete.
Adopted code
The Town of Columbine Valley has adopted the 2024 International Building Code and International Residential Code, and the 2023 National Electrical Code. The Town additionally publishes its own roofing-specific requirements: an ice barrier is required on eave edges for all new roof tear-offs, extending 24 inches from the exterior wall; drip edge metal is required at eaves and gable ends, extending a minimum of 2 inches onto the roof surface and 1.5 inches over the exposed decking edge; total net free roof-vent area must be at least 1 square foot per 150 square feet of roof area; nail-down mineral surfaced roll roofing is not allowed (adhered or torch-down only, per manufacturer instructions); deformed neoprene plumbing vent flashings and rusted/damaged flashing, attic vents, and furnace-to-fireplace vents must be replaced; open-valley flashing must be a minimum 24-inch-wide, 26-gauge galvanized steel; wall-to-roof flashing and counter-flashing are required (counter-flashing may be omitted if the wall flashing's top edge is covered by approved exterior siding); and asphalt shingles must be fastened to solidly sheathed decks, with solid sheathing required if spaced decking gaps are 0.25 inch or greater.
Drip edge
Required — The Town's own building-codes webpage states: "Provide drip edge metal at eaves and gable ends. Eave and gable drip edge metal shall extend a minimum of 2 inches onto the roof surface and 1.5 inches over the exposed decking edge." The codified § 15.08.020(b) IRC amendments (Ord. No. 2, Series 2023 recodification) do not separately address R905.2.8.5/drip edge. About drip edge
Ice & water shield
Required — § 15.08.020(b)(3)'s design-criteria fill-in prints "Ice shield underlayment requires Yes (see Sec. 1507.2.8.2)." This corroborates the Town's own building-codes webpage, which independently states: "Ice barrier shall be used on the eave edge for all new roof tear-offs. The ice barrier shall extend 24 inches from the exterior wall." About ice & water barrier
Impact-resistant roofing
Not required — Columbine Valley Municipal Code § 15.08.020, Amendments (subsections (a) through (j), covering the IBC, IRC, Plumbing, Fuel Gas, Mechanical, Property Maintenance, Energy Conservation, Fire, and Swimming Pool and Spa Codes), was read in full and contains no UL 2218, Class 4, or impact-resistance provision anywhere.
Wind design criteria
Columbine Valley Municipal Code § 15.08.020(b)(3) amends "Section R301.1... by the following paragraph: Design criteria": "Roof snow load 30 psf; Nominal wind speed 110 mph; Ultimate wind speed 120 mph; Frost depth 36 inches; Seismic design category B; Termite Slight to moderate; Decay None to slight; Weathering Severe; Winter design temperature 1 degree; Degree heating days 6,200; 100-year hourly rainfall 2.67 inches per hour." (Printed under the section citation "R301.1" as drafted by the Town, functioning as its Table R301.2(1)-equivalent climatic design criteria fill-in.)
Sales & use tax
7.25% combined (Town of Columbine Valley 3% + State of Colorado 2.9% + RTD 1.0% + Cultural Arts Tax (SCFD) 0.1% + Arapahoe County Open Space Tax 0.25%), per the Town's own Tax Rate page. The Town separately levies a 3% Use Tax, "identical to the Sales Tax except that it is assessed on taxable purchases made in other jurisdictions where the 'taxable merchandise' is 'used' in Columbine Valley. The most common incidence of the Use Tax being levied and collected is when a homeowner builds or makes home improvements. The Use Tax is assessed when the homeowner obtains a Building Permit for the project, and it is based on the estimated taxable materials to be used in the project. Evidence of payment of this tax is confirmed in the Building Permit, which can be presented to a vendor (such as The Home Depot) to eliminate a duplicate city sales tax being assessed."
