The most effective wildfire home-hardening steps, in order of impact-per-dollar, are: (1) ember-resistant vents, soffits, and gutter guards; (2) a noncombustible 0–5 ft defensible-space zone; (3) a Class A roof; (4) fire-resistant siding and decks; and (5) multi-pane or tempered windows.
In Colorado, hardening work must comply with the Colorado Wildfire Resiliency Code (CWRC). State and county incentives may offset costs, and documented mitigation can affect insurance availability and premiums.
Understand your risk and the rules
Colorado's wildland-urban interface is among the highest-risk in the country. The CWRC sets statewide standards for fire-resistant construction in high-hazard areas, governing roofing, siding, decks, vents, and windows. Research from the IBHS and NFPA 1144 shows hardening can cut a home's ignition vulnerability dramatically.
The five upgrades that matter most
1. Ember entry points
Vents, soffits, and gutters are the #1 cause of home loss. Sealing them is the cheapest high-impact step.
2. The first five feet
A noncombustible 0–5 ft zone stops embers collecting against the home.
3. A Class A roof
The largest ember target; a Class A assembly is often required and insurer-recognized.
4. Siding & decks
Noncombustible cladding and fire-rated decks resist radiant heat and ember beds.
Incentives and insurance
Wildfire mitigation in Colorado is supported by state and county programs, and qualifying expenses may be eligible under a state income-tax measure. Programs and eligibility change over time and differ by county, so we help you find the current, applicable resources during your assessment.
If your insurer has flagged wildfire risk, documented hardening can help. We prioritize the upgrades insurers look for and provide completion certificates and IBHS program guidance you can submit for review. See our FAQ for details on insurer notices.
