Roof Fire Protection Recommendations

03.20.22 08:23 AM By Noe

In the last few years, our county has witnessed wildfires that have caused damage and loss of homes. The Cal fire website is a wonderful resource in ensuring that your home is protected the best it can be. Below is an excerpt from Cal Fire:

Roof: The roof is the most vulnerable part of your home. Homes with wood or shingle roofs are at high risk of being destroyed during a wildfire. 

  • Build your roof or re-roof with materials such as composition, metal, clay or tile. Block any spaces between roof decking and covering to prevent embers from catching. 
  • Remove accumulated vegetative debris from the roof.

Vents: Vents on homes create openings for flying embers. 

  • Cover all vent openings with 1/16-inch to 1/8-inch metal mesh. Do not use fiberglass or plastic mesh because they can melt and burn.
  • Use Ember and flame resistant vents (WUI vents).

Eaves and Soffits: Eaves should be boxed in (soffited-eave design) and protected with ignition-resistant* or non-combustible materials.

Rain Gutters: Keep rain gutters clear or enclose rain gutters to prevent accumulation of plant debris.

  • Install a corrosion-resistant and noncombustible metal drip edge for additional protection of the combustible components on your roof’s edge.
  • Use a noncombustible gutter cover to prevent buildup of debris and vegetation in the gutter.
defensible space zones

Zone 1 – Lean, Clean and Green Zone

Zone 1 extends 30 feet from buildings, structures, decks, etc. or to your property line, whichever is closer.

  • Remove all dead plants, grass and weeds (vegetation).
  • Remove dead or dry leaves and pine needles from your yard, roof and rain gutters.
  • Remove branches that hang over your roof and keep dead branches 10 feet away from your chimney.
  • Trim trees regularly to keep branches a minimum of 10 feet from other trees.
  • Relocate wood piles to Zone 2.
  • Remove or prune flammable plants and shrubs near windows.
  • Remove vegetation and items that could catch fire from around and under decks, balconies and stairs.
  • Create a separation between trees, shrubs and items that could catch fire, such as patio furniture, wood piles, swing sets, etc.

Zone 2 – Reduce Fuel Zone

Zone 2 extends from 30 feet to 100 feet out from buildings, structures, decks, etc. or to your property line, whichever is closer.

  • Cut or mow annual grass down to a maximum height of 4 inches.
  • Create horizontal space between shrubs and trees. 
  • Create vertical space between grass, shrubs and trees. 
  • Remove fallen leaves, needles, twigs, bark, cones, and small branches. However, they may be permitted to a depth of 3 inches.
  • All exposed wood piles must have a minimum of 10 feet of clearance, down to bare mineral soil, in all directions.
