Colorado's roofing contract law (C.R.S. 6-22), the no-deductible-waiver rule, the new Strengthen Colorado Homes resilient-roof grants, the Colorado Wildfire Resiliency Code's Class A roof rules, local re-roof permits and licenses, Class 4 cities, and mechanic's lien deadlines.

1 · Product approvals

Product approvals

Colorado has no statewide roofing product approval system. Local building departments rely on the code's labeling rules and evaluation reports; Class A fire ratings (ASTM E108/UL 790) and Class 4 hail ratings (UL 2218) are proven by the product's listing.

Code evaluation reports (ICC-ES, UL, IAPMO): 48 roofing reports

2 · Permit forms

City re-roof permits

There's no statewide re-roof permit rule. Cities, counties and regional building departments issue roofing permits and most also license contractors.

Colorado Springs (Pikes Peak Regional Building Department)A permit is required for roof replacement; the roofing contractor must be licensed with PPRBD and must request inspections, and a homeowner can pull a permit only for work they do themselves.Fort CollinsA permit is required for roof repair or replacement over one square (100 sq ft), including sheds and detached garages; anyone hired to replace a roof must be licensed.LakewoodA permit is required for any re-roof and for repairs of 100 sq ft or more; existing coverings must be torn off to the deck, hired roofers need Lakewood contractor registration, and inspections are by uploaded photos.

3 · Code rules

Code rules

No statewide residential building code; cities and counties adopt their own IRC edition. State law does require jurisdictions that update any building code to adopt the state model energy code, and the 2025 Colorado Wildfire Resiliency Code sets roof rules in wildfire areas. Official adoption page ↗

Energy code with every local code updateFrom July 1, 2026, a jurisdiction that updates any building code must adopt the Model Low Energy and Carbon Code (based on the 2024 IECC) or stricter; from 2023 to mid-2026 the floor was the 2021 or 2024 IECC with electric- and solar-ready rules.Wildfire code: Class A roof coveringThe 2025 Colorado Wildfire Resiliency Code requires a Class A roof covering or assembly (ASTM E108/UL 790) in mapped wildfire areas, with gaps under the covering blocked against flames and embers.Wildfire code: valleys and the 25% re-roof ruleValleys need at least 0.019-inch corrosion-resistant metal over a 36-inch cap sheet. Replacing 25% or more of an existing roof means the whole roof covering must meet the new-construction rules unless it already complies.Wildfire code: Class 2 areas add eave protectionIn higher-hazard (Class 2) areas the Class A roof rules still apply, plus the exposed underside of eaves and soffits must be noncombustible, ignition-resistant or another approved material; gutters and downspouts must be noncombustible.Class 4 shingles required in Fort CollinsAsphalt shingle re-roofs must use Class 4 (UL 2218) impact-resistant shingles when 50% or more of a roof is replaced; smaller repairs may match the existing material.Fort Collins: two layers max, ice barrier at eavesNo more than two roof layers; with two or more, tear off to the deck. Ice barrier runs at least 24 inches past the inside of the exterior wall, and at least 36 inches up-slope on 8:12 or steeper roofs.

4 · Wind, fire and storm programs

Wind, fire and storm programs

Hail is the big one. SB26-155 created a state grant program for wind- and hail-certified roofs and pushes insurers to pass roof savings to homeowners; the deductible-waiver ban also applies to grant jobs.

Strengthen Colorado Homes grants (SB26-155)Signed June 2026. A new enterprise in the Division of Insurance will fund grants for 'resilient roof systems' with a verified wind and hail certification such as IBHS FORTIFIED; primary homes get priority. Board appointments are due by January 1, 2027.Grant jobs: permits, code and contractor rulesGrant homeowners must pull permits, meet code and pass inspections. Contractors paid with grant money may not waive deductibles, and the board may set installer training standards and a roofing contractor code of conduct.Insurer rate filings must show resilient-roof savingsFor rate filings on or after January 1, 2027, home insurers must show that savings from resilient roofs reach policyholders as discounts or lower premiums, and must report claims data for homes with and without such roofs.No deductible waivers (C.R.S. 6-22-105)On insurance-paid jobs a roofing contractor may not advertise or promise to pay, waive or rebate any part of the deductible. If it does, the insurer can ignore its estimate and the owner or insurer can sue for damages.Roofers can't act as public adjustersA roofing contractor soliciting work may not claim to be or act as a public adjuster, but with a valid contract it may discuss the repair scope with the insurer for the owner.

5 · License and insurance

License and insurance

Colorado has no state roofing license. Cities, counties and regional building departments license roofing contractors locally, so check each jurisdiction before pulling a permit.

Pikes Peak Regional Building: Building Contractor D (Specialty)Covers Colorado Springs and El Paso County. Roofing is one of the single-trade specialties under the B-D license, and homeowners are told to make sure their roofer is licensed with PPRBD.Fort Collins contractor licenseAnyone hired to replace a roof must be licensed. Workers the licensed contractor brings in must be listed on the permit and be licensed or registered as exempt workers, with the licensed contractor supervising on site.

6 · Lien and contract forms

Lien and contract rules

C.R.S. 6-22 sets what a residential roofing contract must say and gives owners 72-hour cancel rights. Colorado's mechanic's lien law needs a 10-day notice of intent, a lien statement within 4 months, and a suit within 6 months.
