Defensible Space

Roof Saver Sprinklers System

Defensible space is an area around a structure where fuels and vegetation are treated, cleared or reduced to slow the spread of wildfire towards the structure. It also reduces the chance of a structure fire moving from the building to the surrounding forest. Defensible space provides room for firefighters to do their jobs. Your house is more likely to withstand a wildfire if grasses, brush, trees and other common forest fuels are managed to reduce a fire’s intensity.

Quick Facts on Defensible Space:

  • Wildfire will find the weakest links in the defense measures you have taken on your property.
  • The primary determinants of a home’s ability to survive wildfire are its roofing material and the quality of the “defensible space” surrounding it.
  • Even small steps to protect your home and property will make them more able to withstand fire.
  • Consider these measures for all areas of your property, not just the immediate vicinity of the house.
  • Quite often during a wildfire threat, fire agencies will pre-deem a home a “casualty” because of bad defensible space. This decision is made before the fire gets there!! This means the agency will use resources on a home with a better chance of survival.
  • Check with your fire agency for local requirements
