Living in a High Fire Hazard Severity Zone (HFHSZ) means taking proactive steps to protect your home from wildfires. Fire-resistant design elements can help prevent embers and flames from causing significant damage. Below are key improvements homeowners can make to fortify their homes against fire threats.
1. Upgrade to Vulcan Eave Vents

Eave vents are necessary for attic ventilation, but standard vents can allow embers to enter and ignite the roof structure. Replacing traditional eave vents with Vulcan eave vents significantly reduces this risk. These specially designed vents use fire-resistant mesh and an intumescent coating that expands when exposed to heat, effectively sealing off ember entry points.
2. Protect Your Eaves with Non-Combustible Soffits

Many homes built in the 1950s and earlier have exposed wood decking on the eaves, which is highly flammable. Adding a non-combustible soffit can protect these vulnerable areas. Consider using stucco or fiber cement siding, such as James Hardie products, to enclose and fireproof your eaves.
3. Install Class A Fire-Rated Roofing

Your roof is one of the most vulnerable parts of your home during a wildfire. Installing a Class A fire-rated roof provides the highest level of fire resistance. Many asphalt shingles meet this rating and are an affordable option. Additionally, standing seam metal roofing is another excellent choice, offering superior fire resistance and durability.
4. Replace Flammable Siding with Fire-Resistant Materials

Older homes often feature wood shingles or siding, which can ignite easily. Upgrading to non-combustible materials such as fiber cement siding from James Hardie or applying stucco can significantly reduce fire risk. These materials not only improve fire resistance but also enhance the longevity and durability of your home’s exterior.
5. Upgrade to Dual-Pane Tempered Windows

Single-pane windows found in many older homes are highly vulnerable to heat and can shatter quickly during a wildfire, allowing flames and embers inside. Replacing them with dual-pane tempered glass windows and doors provides better insulation and greater fire resistance. Consider vinyl, metal-clad, or metal-framed options for added durability.
There was a study done about the fires in California between 2013 – 2018 in counties that were most affected to look at the damages of the structures and the different aspects of them. Stay tuned for next week’s blog to see what key elements we think are important for you to be aware of!
