Why siding is the wildfire problem

Wood siding is the largest continuous combustible surface on the house. Embers don't need flame contact. They lodge at the base of the wall, in vents, and at roof-to-wall corners, and the siding carries the fire.


Replacing it with fiber cement removes the fuel. But new siding alone leaves the entry points open. This system closes them.

Meets Boulder County ignition-resistant construction requirements

The completed scope meets Boulder County's ignition-resistant construction requirements for the wildland-urban interface. Fire Ready Exteriors pulls and manages the building permit, plan review, and inspections. Read the county's requirements in Building Publication B-37: Ignition Resistant Construction.

What's included on every job

None of this is an upgrade. The wildfire details are the system.

Close-up of fiber-cement lap siding and trim

Noncombustible cladding

James Hardie fiber cement (ASTM E136 noncombustible), panel-and-batten or lap, ColorPlus® factory finish or primed-and-painted.

Removes the fuel at the wall.

Fiber-cement siding with flashed window openings

New weather barrier and flashing

House wrap, flashing tape at every opening, Z-flashing at panel joints, corrosion-resistant fasteners.

Keeps water out for the life of the siding.

Stainless steel mesh ember-resistant attic vent

WUI-listed ember-resistant vents

1/8" stainless mesh with intumescent baffle at soffit and gable vents.

Standard aluminum vents let embers into the attic. These are the listed replacement.

Noncombustible trim at the base of a sided wall

Noncombustible base-of-wall

Fiber-cement trim at grade, decks, and hardscape.

The most common ignition point on a sided wall.

Kickout and roof-to-wall flashing

Metal kickout flashing where the eave meets the wall, plus roof-to-wall flashing behind the siding.

Diverts runoff into the gutter and closes the corner where embers and debris collect.

Fiber-cement soffit and fascia

James Hardie soffit panels and fascia trim, replacing wood or vinyl.

Encloses eaves so embers can't reach the attic framing.

Metal gutter guard installed on a seamless gutter

Seamless gutters with metal guards

New seamless gutters with metal gutter guards at every run.

Keeps needles and leaves out of the gutter, where debris against the roof edge ignites.

Who this is for

Questions we get

Does fiber cement burn?

No. James Hardie fiber cement is recognized as noncombustible under ASTM E136. It does not ignite from ember contact or radiant heat the way wood or vinyl does. Panels, trim, soffit, and fascia are all fiber cement, so no combustible cladding is left on the wall.

Will this lower my insurance?

It gives you a documented case. Under Colorado HB25-1182, insurers must consider property-level wildfire mitigation and let you appeal your wildfire risk score with evidence. The Mitigation Documentation Package is built for that appeal. Whether a carrier applies a discount, and how much, is the carrier's decision.

Do you handle the permit?

Yes. Fire Ready Exteriors is a licensed Boulder County general contractor. We pull the building permit, submit for plan review, and schedule the inspections.

How long does it take?

You get a proposal within 5 business days of the assessment. ColorPlus orders carry a 2 to 4 week factory lead time. Install duration depends on the size and condition of the house, and you get a schedule at signing.

What about my deck?

The re-side includes noncombustible trim where the wall meets the deck. The deck itself is a separate scope: under-deck screening is part of Ember Control, and fire-rated deck work is its own project. Both can be assessed in the same visit.
