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.

Disaster resources available to prepare for heat, wildfire, power outages, quakes

September is National Preparedness Month, designated to encourage disaster and emergency readiness. To help Californians prepare for extreme heat, earthquakes, public safety power shutoffs and wildfire, University of California Cooperative Extension has created a disaster preparedness website organized for quick access to critical information.

The website https://ucanr.edu/Disaster contains fact sheets with tips for getting prepared.

“Unfortunately, with a warming climate, we are facing more and more extreme climate-related events such as heat waves, wildfires, power shutoffs and storms. All Californians need to step up their preparedness efforts to be ready to meet this more uncertain future,” said Susan Kocher, UC Cooperative Extension forestry advisor, who co-authored the disaster preparedness resources for the website.

Extreme heat

The fact sheet for extreme heat events offers suggestions for avoiding heat exposure, such as identifying nearby cooling centers and covering windows to keep heat out. It also suggests things to do during hot weather such as staying hydrated, taking cool showers and keeping pets indoors. It describes symptoms of heat-related illnesses, which can have serious health effects.

Public Safety Power Shutoff

During extreme weather events, electrical power in high fire-threat areas may be shut off to prevent sparking. This precaution is known as a Public Safety Power Shutoff. A PSPS is most likely to occur from May to November, when conditions are the hottest and driest.

UC Cooperative Extension recommends signing up to receive PSPS alerts from your energy company. Experts also advise making a plan for medications that need to be refrigerated or medical devices that require power. To prevent foodborne illness, they offer suggestions for ensuring food safety during and after a power outage.

Wildfire and smoke

Wildfire smoke can harm your health. During wildfires, UC Cooperative Extension recommends wearing an N95 outdoors to reduce smoke exposure and taking steps to prevent smoke from entering buildings. To reduce wildfire risk, the website describes methods of removing flammable vegetation around homes.

Earthquakes

UC Cooperative Extension offers safety tips for before, during and after an earthquake. Identifying the safest place in your home during an earthquake in advance is helpful. For example, doorways are not the safest place to be in modern homes. Experts recommend crawling under a sturdy desk or table, while avoiding areas next to windows, beneath ceiling fixtures or near large items that may fall during an earthquake.

The website also offers resources on drought, food safety after a fire, and wildfire preparedness and recovery.

In 2020 and 2021, Cooperative Extension researchers from around the country held listening sessions with community members who had experienced extreme weather events and other types of disasters to learn what had worked well, what had not, and how communities could be strengthened. 

In response, these disaster resources were developed by Kocher, UC Davis undergraduate student Caydee Schweitzer, Tracy Schohr, UC Cooperative Extension livestock and natural resource advisor, and Vikram Koundinya, UC Cooperative Extension evaluation specialist. The group plans to add fact sheets on more disaster topics in the future.

This project was funded by a USDA National Institute of Food and Agriculture Renewable Resources Extension Act grant.
