Living with wildfire

Steps you can take to “Harden your home”

Looking back at the wildfires of 2018, it is hard to imagine there is anything a homeowner could do to prepare for a wildfire the magnitude of the Carr, the Camp Fire and others in northern California. Combined with exceptionally dry fuels, these fires occurred during extreme fire weather conditions that lined up for the perfect firestorm.

Firefighters know that embers are the most important cause of home ignition. Research shows that two out of three homes destroyed during wildfires are ignited by wind-blown embers, and not from the actual flames of the fire. These embers can ignite and burn your home in several ways, and can travel as far as a mile from the main fire. By taking one hour today to clean your roof and gutters, you’ll have taken the first, and possibly the most significant step, towards protecting your home. Photo submitted

Fortunately, these events are not the norm and do not make up the largest percentage of conditions that firefighters are faced with during initial attack of the thousands of wildfires that occur each year in northern California.

As we watch the news and read articles about the home destruction, there are homes that survived a wildfire. Was it luck or faith? No one knows for sure, but one thing many had in common was that homeowners were aware that they lived in a wildfire environment and took steps to prepare for it.

Give your home a chance, Understanding wildfires and embers


Embers are the most significant cause of home ignition. Research indicates that many homes destroyed are ignited by wind-blown embers- not from the actual flames of the fire! These embers are capable of igniting and burning your home in several ways. In order to have a wildfire-safe home, two equally important steps must be implemented: 1) the selection of building materials and designs that will help the home resist the wildfire; and 2) the creation of adequate defensible space, based on the selection, placement, and maintenance of vegetation within 100′ of all structures or more on steep slopes.

As we head into spring, here are some tips to “Harden your Home” from the wildfire researchers at the Insurance Institute of Building and Safety (IBHS). It is a good time to take a look at your roof, your vents and the 5-foot non-combustion zone around your home and see how you’re looking and get ahead of it before fire season is upon us.

Look at your roof, the most vulnerable part of your home

Block any spaces between roof decking and covering to prevent embers from getting in those vulnerable areas. Embers can land in the smallest areas and start a fire and you or firefighters may not even be at your home when it happens. Homes with wood or shingle roofs are at high risk of being destroyed during a wildfire. If you still have a wood roof, this should be number one on your priority list to re-roof your home a fire resistant roof. This truly is your number one defense for wildfire. Your roof on fire means every neighbor in your area is at risk due to burning wood shakes being carried by the wind throughout your neighborhood and starting new fires.


Eaves and soffits

Open eaves are more vulnerable to both ember entry and direct flame contact exposures in comparison to soffited eaves. Eaves and soffits should be protected with ignition-resistant or non-combustible materials. The IBHS research center suggests that if you have open eaves, use a sealant (such as caulking) to cover gaps, or enclose the underside of the roof overhang. It is yet another spot embers can land in and start burning.

Check your vents

Remember many homes actually ignite from the inside during a wildfire when powerful winds blow embers into the home through attic, crawlspace or dryer vents. IBHS recommends that 1⁄4-inch. (6 mm) mesh screening should not be used to cover any vent. Finer mesh sizes of 1/8-inch. (3 mm) or 1/16-inch (1.5 mm) would be preferred. The finer 1/16-inch mesh screen will require more cleaning-related maintenance to remove the debris that can accumulate on the screen surface. Do not use fiberglass or plastic mesh because they can melt and burn. Use manufactured and California approved vents to retrofit existing attic, soffit, basement, foundation and gable vents where possible. Consult with a building contractor, architect or engineer to ensure that adequate ventilation exists when installing ember resistant vents, which may restrict airflow.


Rain gutters

This is a very vulnerable place for a fire to start. Imagine an ember landing in your gutter filled with dry leaves and pine needles from the windstorm that happened just the day before. How many times a year do you get on a ladder and clean your gutters? You just cleaned them and they are full again! The best option for homeowners is to screen with gutter guards or covers. There are a variety of manufacturers and contractors available to do this.

What about the garage?

Install weather stripping around and under the garage door to prevent embers from blowing in. Install a battery backup to your garage door opener to ensure you can open and CLOSE it when evacuating, especially in the dark. Practice opening the door manually if you do not have a battery backup, since the power may be out when a wildfire approaches.


Have a fire extinguisher and tools such as a shovel, rake, bucket and hoe available for fire emergencies in your garage.

Create a no-burn zone closest to home

Homeowners should also create a “non-combustible” zone within 3-5 feet of the house. This includes the entire footprint of the deck and 6 inches vertically upward from the ground to the start of your siding. Swap out any bark mulch use rock mulch (gravel) in that location. That also includes the vertical space around your house; make sure tree limbs and shrubs are trimmed back with zero dead vegetation in this area.

Your home’s siding also matters. There are many flame-resistant siding materials on the market. Take a look and make sure your siding doesn’t directly touch the ground. If your siding reaches all the way to the ground, embers can accumulate at the base of the wall and ignite the siding. One idea is to expose 5-6 inches of concrete at the base of the wall. You can also install metal flashing to protect it, making sure it’s tucked under the siding so water doesn’t accumulate inside it. Fiber cement boards are also an option. Be sure to keep the area underneath your deck free of anything that could possibly catch fire. Think embers — they can get in to the smallest spaces. A stack of wood, a pile of leaves or pine needles, your cardboard that you were going to recycle … remember wind likes to funnel underneath your deck and it is a very vulnerable spot.
