Ember-Resistant Retrofits

Home Hardening for Wildfire in Colorado

Most Colorado homes lost to wildfire don't burn from the wall of flame, they burn hours later from wind-driven embers that slip into a vent, pile up in a gutter, or ignite a bark-mulch bed against the siding. Home hardening closes those gaps. We match you with a vetted, fully-qualified crew to harden the structure itself, and document the work for funding, so an ember-resistant home can survive an ember storm even when the fire never reaches the front door.

The Home Ignition Zone

Where embers attack, and how each point gets hardened

A home is only as strong as its weakest opening. The plan we build addresses every entry point in the home ignition zone, from the roofline down to the first five feet of ground, and your matched crew handles the work.

Vents & openings

Open or large-mesh vents are one of the most common ways embers enter an attic and burn a home from the inside out.

  • Retrofit attic, soffit, gable and crawlspace vents to 1/8" noncombustible metal mesh
  • Install listed ember-resistant (wildland-urban interface-rated) vents where required
  • Seal gaps at fascia, dormers and pipe penetrations

Roof & gutters

Embers collect in valleys, edges and gutters, the places where roof debris ignites and carries fire to the structure.

  • Confirm or upgrade to a Class A roof assembly
  • Clear and protect valleys, edges and roof-to-wall intersections
  • Install noncombustible metal gutter guards to stop debris ignition

Decks & under-deck

The space beneath a deck traps embers and stored combustibles, turning an outdoor feature into an ignition trap.

  • Enclose or screen the under-deck area where embers collect
  • Recommend ignition-resistant decking and noncombustible deck-to-wall details
  • Remove stored combustibles beneath and around decks

Siding & walls

Lower siding courses and combustible trim give surface fire a foothold against the structure.

  • Inspect and seal siding gaps, especially the lower courses
  • Recommend noncombustible or ignition-resistant siding at vulnerable walls
  • Address combustible trim and corner details

Windows & glazing

Single-pane and large-pane windows can fail under radiant heat, opening the interior to flame and embers.

  • Identify single-pane and large-pane windows at risk of radiant failure
  • Recommend dual-pane / tempered glazing upgrades
  • Address combustible window framing and screens

Zone 0, the first 5 feet

The noncombustible five feet against the wall is the single highest-impact area, because most homes ignite from embers landing close to the structure.

  • Create a noncombustible 5-foot ember-resistant zone at the foundation
  • Remove bark mulch, woodpiles and combustible plants against the wall
  • Replace combustible fencing that connects directly to the house

Why It Matters Here

Colorado conditions make ember intrusion worse

Research from post-fire investigations across the wildland-urban interface consistently shows that the great majority of homes destroyed in wildfires ignite from embers and surface fire near the house, not from the radiant heat of the main fire front. That's good news: ember vulnerabilities are physical, specific and fixable. A house with screened vents, a clean Class A roof, a noncombustible five-foot perimeter and protected decks is dramatically more likely to be standing when you return.

Decades of bark-beetle mortality have left stands of dead, resin-rich timber across Colorado's high country. These fuels throw enormous volumes of embers far ahead of the main fire, sometimes more than a mile, which is exactly why the structure itself must be hardened. The same downslope wind events that drive Front Range fires also drive embers horizontally into soffit vents, deck gaps and gutters. And in Colorado Springs, Boulder County, El Paso County and the foothills, homes sit close together within the wildland-urban interface, so one ignited home throws embers at the next and neighborhood-scale hardening multiplies everyone's odds. We work to NFPA 1144 and Colorado State Forest Service guidance, and we align upgrades to the IBHS Wildfire Prepared Home standard so your work counts toward recognition, insurance discounts and grant reimbursement. Home hardening pairs best with defensible space around the property and a wildfire risk assessment to prioritize the highest-impact upgrades.

Our Process

How a home hardening project runs

1

Assess

We walk the full home ignition zone, score vulnerabilities against NFPA 1144 and Wildfire Prepared Home criteria, and photograph every finding.

2

Prioritize

You get a written, prioritized plan that puts the highest-impact, lowest-cost items first, usually vents, Zone 0 and gutters before larger retrofits.

3

Harden

Your matched crew retrofits vents, installs gutter guards, addresses decks and siding, and clears the noncombustible perimeter to spec.

4

Document

We deliver before/after photo documentation formatted for insurers, the Colorado tax credit and Wildfire Partners certification.

Funding

Most of this can be reimbursed

Colorado homeowners can claim a 25% state wildfire mitigation tax credit (up to $625 per year), and many qualify for CSFS cost-share grants and Wildfire Partners rebates. We itemize and document your project so it qualifies.

FAQ

Home hardening questions

What is home hardening for wildfire?

Home hardening is upgrading the most ignition-prone parts of a house, vents, roof, gutters, decks, siding and the first five feet around it, so that wind-driven embers cannot find a way in. Embers, not direct flame, destroy the majority of homes lost in Colorado wildfires, so hardening targets those ember entry points.

What is Zone 0 and why does it matter?

Zone 0 is the noncombustible five-foot ember-resistant zone immediately around your home. Keeping it free of bark mulch, woodpiles, plants and combustible fencing within five feet of the wall is the single highest-impact step you can take, because most homes ignite from embers landing close to the structure rather than from the flame front itself.

Do I need to replace my whole roof?

Not always. Many Colorado homes already have a Class A roof covering. We assess the roof, the edges, valleys and gutters where embers collect, and recommend the most cost-effective path, which is often gutter guards, metal edge details and debris removal rather than a full replacement.

Will home hardening help with insurance?

Yes. Insurers increasingly recognize ember-resistant retrofits and programs such as Wildfire Prepared Home. We photo-document every upgrade so you can submit it for non-renewal disputes, premium discounts, the Colorado wildfire mitigation tax credit and Wildfire Partners certification.

What does ember-resistant vent screening involve?

The crew we match you with replaces or retrofits attic, soffit, gable and crawlspace vents with 1/8-inch noncombustible metal mesh or listed ember-resistant vents. Open or large-mesh vents are one of the most common ways embers enter an attic and burn a home from the inside out.
