Protect Your Home from Wildfires
The most effective home safety actions occure within 100 feet of your home
Luckily, it is possible to retrofit your home to be ember and flame resistant. And some of the most effective modifications only cost a few dollars. Read on to find out what you can do.
The best time to prepare is long before fire season.
Think of Fire Safety in Zones
This is the most important zone where any ember that lands on flammable material could be deadly. This zone is so important, we break this down in its own section below. Scroll down to see the most effective fire risk reduction actions.
ZONE 0: 0-5 feet
This area immediately surrounding the home should be 100% non-flammable material such as a concrete pathway or a rock garden. Instead of growing plants or garden beds where flames can easily ignite the house if they become dry, move them a few feet from the house. Also, a wood or plastic fence can act as a wick, bringing fire from neighboring homes or vegetation right to your doorstep! Make sure the 5 feet of fence connected to your house is a non-combustible material like metal.
ZONE 1: 5-30 feet
Defensible space is most important in this zone. Imagine giving firefighters a more open area to work. Reduce continuous tree cover so that the fire cannot easily jump from one treetop to the next. Trim any branches that overhang the house. In a wind event, they will drop burnable leaves and needles on your roof and in your gutters, creating a perfect bed for an ember to ignite.
ZONE 2: 30-100 feet
Research shows that this zone is less important but still wise to keep irrigated and shady when possible. Large trees can be left to grow here but trimming branches that touch neighboring trees is advised. Clearing vegetation farther than 100 feet from your house can have a negative effect on fire safety as it can allow sunlight to dry shrubs and grass, making them more flammable. So, don’t overdo it!
ZONE HOME – How To Prepare Your House
Here are the most important steps to take in order of importance based on the work of Dr. Alexandra Syphard:
1. Roof – Ensure your roof is non-flammable. Generally, this means that if you have a wood roof, you must replace it with asphalt, metal, or another non-flammable material.
2. Windows – Heat and debris blown by strong wind can crack single window panes and allow embers to burn the home from the inside out. Replace single-pane windows with double or tripple paned windows where the outside pane is tempered glass. This is not cheap but comes with the added benefit of increased energy efficiency for heating and cooling.
3. Air Vents – Most houses have vents into the attic and/or crawl space below the house. If these are not covered, embers can blow in on a strong wind and burn the house from the inside out. Cover these vents using wire mesh with 1/8th inch openings or smaller. This can cost just a few dollars per vent and could prevent your home from burning down.
4. Gutters – Keep your gutters clean! Don’t give embers a place to grow. Replace vinyl cutters with metal. Consider covering your gutters.
5. Siding – If flames come within 30-60 feet of your house, a non-flammable siding material such as hardy plank or even brick is advised. This is especially important if you have wood shingle siding.
