During recent wildfires, 90% of homes and buildings were first ignited by embers, not the actual fire. Embers are carried on winds ahead of a fire, eventually causing a fire to “spot” ahead of itself. Spotting can occur several miles ahead of the main fire! Once these embers land on or near your home, it’ll depend on the building materials and the landscaping (or lack thereof) around the structure how well your house will fare.

Ignition during a wildfire is the result of:

Retrofitting your home with a Class A fire-rated roof, replacing vent screens with 1/8th mesh screens or slatted screens, enclosing eaves, replacing single-pane windows with double pane and screened windows are well worth the investment.

The roof of your home plays an important part in the defense against ember cast. Major wildfires can “spot ahead” miles from the fire front, igniting vegetation and homes well ahead of the main fire.

Cleaning your roof and keeping it free from debris and leaves is a recurring chore. Keep in mind, safety first. A sturdy ladder to access your roof and a person to hold the ladder are a must. The ladder can also be used by firefighters if they are attempting to defend your home from an approaching fire.

Wait until the roof is dry, slipping on a wet or icy roof – even a relatively flat one –  can lead to a fall and injury. Use a leafblower if available, or a broom. Using a garden hose to clean off a roof wastes water and increases the risk of a fall.

If your gutters don’t have debris guards (mesh or solid) installed, make sure to remove all leaves and debris accumulated. In case of embers falling on your house, any leaves in the gutters will ignite and set the roof on fire faster.

According to the Nevada County Building Department, new roofs building guidelines include:

Roofing vents must be made out of ignition-resistant materials and have openings of 1/8”-1/16” only. Your favorite hardware store has these vents in stock, replacing them is an inexpensive way to reduce ember intrusion into the attic.

Exposed and closed eaves need to be built with non-combustible or ignition-resistant materials. If your home has open eaves, removing spiderwebs and other debris goes on your chore list when cleaning your roof.

Don’t forget the shed

Carports, barns, sheds and any other structure on your property (think well house) need to be kept free of leaves, just like your home.

The Nevada County Building Department has resources available to help you upgrade any aspect of your home. Start by downloading their WUI brochure or the WUI Homeowner checklist for an overview of the latest building standards.

The State Fire Marshal has issued Wildfire (“CBC Chapter 7A”) Code Compliance Policies and Accepted Products. A searchable database of WUI building materials is available on the Office of the State Fire Marshal’s website.

Wood stoves, chimneys and proper ash disposal

Wood stoves are popular in the area, be that as a primary or backup heat source. Burning safely not only reduces health risks but also reduces the chance of chimney fires.

Be a good neighbor, build small hot fires rather than large smoldering ones. Using seasoned hardwoods produces much less smoke. Install smoke detectors/carbon monoxide sensors in your home or check the batteries of existing smoke detectors.

The Northern Sierra Air Quality Management District provides these three Burn Wise Tips:

1. Save money and time. Burn only dry, seasoned wood and maintain a hot fire.

2. Keep your appliance properly maintained.

3. Keep your home healthy by upgrading to an efficient, EPA-approved wood-burning appliance.

Can your ashes, have stoves and chimneys inspected and maintained

Proper disposal of ashes reduces fire danger for you and your neighborhood, especially during the Fall shoulder season. Firefighters regularly respond to vegetation fires caused by still hot ashes or BBQ coals improperly disposed of. Embers from hot ashes easily reignite!

Next week we’ll repack Go Bags – for humans and pets – and talk about pet and animal evacuation preparedness.
