Five things you can do this weekend to help protect your home from wildfire

Despite recent rains, fire remains a danger across California, as there's still plenty of time this fall for grass, woody debris and other flammable material to become dry and ignite.

“The smaller the fuels – pine needles, grass, and small twigs – the faster they can dry out, meaning they will be ready to burn again a few days or weeks after a large rainstorm,” said Susie Kocher, a UC Cooperative Extension forestry and natural resources advisor for the Central Sierra, urging residents to take steps to prevent or limit potential fire damage.

When it comes to “home hardening” and essential wildfire preparations in this age of drought and climate change, not every project requires a bank-breaking budget and an army of contractors.

There are small – but significant – home and landscaping improvements that most people can complete by themselves during a single weekend, with a quick run to the hardware store and some basic planning and safety precautions.

“There are a lot of factors that play into your home's vulnerability to ignition; small changes and upgrades can help reduce some of that risk for people living in high wildfire risk areas,” Kocher explained. “The bigger projects like replacing windows and roofs are very important, but there are definitely smaller projects that people can tackle right away at lower cost that also reduce risk. The main goal of these actions is to reduce the risk that wildfire embers can ignite your home.”

Kocher recommends these five measures as simple but crucial ways to bolster your home's wildfire resiliency.

Clean debris from your roof. Because of its expansive surface, the roof is the most susceptible area of your house to embers. Removing accumulated leaves and needles is especially important if you have a “complex roof” with dormers or other elements – that's where embers gather, too, and could come in contact with flammable siding. (And while you're up there, give those gutters a good swabbing.) Learn more about protecting your roof and gutters.

Install metal flashing in vulnerable spots. Replacing all your siding with noncombustible material can be pricey, but a more manageable task would be adding corrosion-resistant metal flashing to select areas: roof-to-wall intersections, the place where the chimney comes out of the roof, and the edge where the deck meets the house. Learn other ways to shore up your siding.

Remove debris from between the boards of your deck and fence. Embers can ignite leaves and needles stuck between the boards, so be sure to keep those gaps clean and clear. Learn additional steps to harden your deck and prepare your fence.

Take out all vegetation (alive or dead) within five feet of your home. Creating defensible space immediately next to your home is a top priority, so be sure there's nothing combustible within this “Zone Zero.” Plants, mulch, woodpiles, wicker furniture or anything that can catch fire should be removed. Learn what to do in the other “zones” as you move farther from your home. 

Inspect vents and upgrade to finer mesh screens. Install or swap in noncombustible, corrosion-resistant metal mesh screening that is at least 1/8” (1/16” would be even better but requires more frequent maintenance). These screens help prevent embers from entering your attic and crawl space. In addition, put together some vent covers that can be deployed if you have time before a wildfire arrives. Learn other ways to reduce vulnerability of vents.
