Westlake Village sits in one of California's most fire-prone corridors. The Santa Ana winds, dry chaparral hillsides, and increasingly unpredictable fire weather have turned home hardening from a nice-to-have into a non-negotiable for every serious homeowner in the Conejo Valley. And yet, most homes — even newer ones — have critical vulnerabilities that most owners don't know about until it's too late.
This checklist is based on our team's direct experience performing hundreds of fire-hardening assessments across Westlake Village, North Ranch, Lake Sherwood, and Agoura Hills. Each item is ranked by its potential impact on your home's survivability during a wildfire event.
Why Home Hardening Matters More Than Ever in 2026
CAL FIRE and the Insurance Institute for Business & Home Safety (IBHS) have both confirmed what we see in the field: the vast majority of homes that burn during wildfires ignite not from direct flame contact, but from airborne embers landing in vulnerable spots — vents, gutters, wood decking, and gaps in siding.
The good news is that most of these vulnerabilities can be addressed with targeted, cost-effective upgrades. You don't need to rebuild your entire home. You need to know where the weak points are and fix them strategically.
California Insurance Alert: Several major insurers have exited the California market or significantly raised premiums in fire-risk zones. Documented fire-hardening upgrades are now one of the most effective ways to qualify for coverage and reduce premiums. Ask us about our assessment documentation package.
The 12-Point Fire Hardening Checklist
Work through this list from the top of your home down. The roof and attic are your highest-priority zones — once fire enters your attic, survival odds drop dramatically.
- 01
Upgrade to a Class A Fire-Rated Roof
Your roof is the largest surface area exposed to ember fall. Class A is the highest fire-resistance rating — look for materials like concrete tile, clay tile, or Class A asphalt shingles. Wood shake roofs, even treated ones, do not provide adequate protection and may violate current local fire codes in Westlake Village.
- 02
Install Ember-Resistant Vents (WUI / Vulcan Approved)
Attic vents are the #1 entry point for embers. Standard vents have openings large enough for burning debris to enter and ignite your attic. Replace them with Wildland Urban Interface (WUI) approved vents with 1/16" or finer corrosion-resistant mesh. Brands like Vulcan Vents are CAL FIRE compliant and specifically designed for this purpose.
- 03
Seal All Attic and Eave Gaps
Any gap, crack, or open joint in your eave or attic structure is an ember entry point. Use fire-rated caulk and intumescent materials to seal every gap — including around pipes, wires, and where siding meets the roofline. This is tedious work but extremely high impact.
- 04
Replace Wood Siding with Non-Combustible Alternatives
Fiber cement siding (HardiePlank), stucco, and metal panel systems all offer significantly better fire resistance than wood. If full replacement isn't in the budget, prioritize the areas closest to the roofline, corners, and any section within 10 feet of decking or vegetation.
- 05
Upgrade to Dual-Paned Tempered Glass Windows
Standard single-pane windows can crack and fail within minutes of radiant heat exposure, allowing fire to enter the home. Dual-paned tempered glass provides a significant barrier — and in many cases, your insurer will offer a premium reduction for this documented upgrade.
- 06
Replace Wood Decking with Non-Combustible Materials
Decks are major fire catchers. Embers land, accumulate under the deck, and ignite from below. Replace wood decking with composite, concrete, or metal alternatives. If replacing the deck isn't feasible, at minimum enclose the underside with 1/8" corrosion-resistant mesh to prevent ember accumulation.
- 07
Box In or Screen Your Eaves (Soffits)
Open-beam eaves look beautiful architecturally, but they're a major fire risk. Enclose them with fire-rated materials or at minimum screen them with fine mesh. Closed soffits with non-combustible material are the gold standard.
- 08
Install Multi-Pane Fire-Rated Garage Doors
Garage doors are often the weakest point on a home's facade. A standard garage door can fail quickly under radiant heat, and once the garage ignites, the fire has direct access to the structure. Look for doors with a minimum 20-minute fire rating and insulated steel construction.
- 09
Create Ember-Resistant Zones Around the Foundation
The 0–5 foot zone immediately around your home is the most critical. Remove all combustible materials — mulch, plants, wood furniture, stored materials — and replace with non-combustible ground cover such as gravel, pavers, or concrete. Nothing that burns should touch your home's exterior.
- 10
Clean and Guard Your Gutters
Gutters full of dried leaves are ember catchers. Install gutter guards with fine mesh screening, and clean gutters at minimum twice per year — before and after fire season. Metal gutters are preferable to vinyl, which can melt and pull away from the roofline.
- 11
Assess and Upgrade Fencing Materials
Wood fencing that connects to your home acts as a direct fire pathway. Replace the 5-foot section nearest to your structure with non-combustible metal or masonry. This single change can interrupt a fire's path to your home's exterior.

Get a Professional Fire-Hardening Assessment
Every home is different. A professional assessment identifies your specific vulnerabilities, documents existing upgrades for your insurer, and creates a prioritized upgrade plan tailored to your property's exposure and budget. We offer free assessments for Westlake Village homeowners — use code HARDEN26 at consultation.
True luxury isn't just about the finish on a countertop — it's the peace of mind that comes from knowing your home is structurally resilient, intelligently designed, and built to endure for generations.

California's home insurance crisis has hit Westlake Village hard. But there's a silver lining: insurers who remain in the market are increasingly rewarding documented fire-hardening upgrades with lower premiums and improved policy terms. The key word is documented.
When we complete a fire-hardening project, we provide clients with a comprehensive upgrade report including materials used, installation photos, product certifications, and CAL FIRE compliance references. This documentation has helped clients successfully negotiate with insurers and in some cases secure coverage that was previously unavailable to them.
What to Do Next
If you've read through this checklist and identified gaps — or if you're simply not sure where your home stands — the most important first step is a professional assessment.
