LAKE TAHOE, Calif. / Nev. September 12, 2019 – Devastating wildfires occur year-round and as the air becomes chilly and the leaves begin to fall, residents are urged to prepare even during the Fall season. One of the ways residents can reduce the wildfire threat is by preparing for embers.

Embers, or pieces of burning material, can travel a mile or more ahead of a wildfire. During a wildfire, thousands of embers can rain down on your roof and pelt the side of your home like a hail storm. If these embers come in contact with flammable material on, in or near your house, it can ignite. In 2008, an Australian researcher estimated that 90% of all homes ignited in wildfires were due to embers.

Being prepared for embers involves creating defensible space and ensuring the home has proper building materials. The following is a list of ways residents can prepare:

Recommended building materials:

  • Replace wood shake and shingle roofs with Class “A” fire-rated roofs such as composition, cement tile or metal.
  • Cover attic and foundation vents with one-eighth inch wire mesh or install ember-resistant vents.
  • Replace single-pane windows with windows that are at least double-paned. Close all windows if a wildfire is threatening.
  • Use concrete or mortar to plug roof openings, such as the open ends of barrel tiles and gaps between tiles along the ridge.
  • Do not store combustible materials under the deck. Instead, enclose deck sides with one-quarter inch or smaller wire mesh to prevent debris from accumulating underneath.

Be ember prepared by utilizing the following defensible space recommendations:

  • Keep rain gutters and roofs free of pine needles and other flammable debris.
  • Move your firewood pile at least 30 feet away from the house.
  • Remove pine needles and other plant debris from the cracks between deck boards. Clean flammable debris from the deck surface.
  • Create a noncombustible area at least five feet wide around the base of the house using gravel, rock, concrete, or irrigated lawn / irrigated plants with high moisture content.
  • Avoid planting evergreen shrubs, such as juniper, next to the house, in front or below vent openings or in front of windows.
  • Do not use wood or bark mulches near the home.
  • Remove dead vegetation and weeds from around the home.
