What are the most fire-resistant roofing materials and vents in the North Bay?

Short answerStart with a Class A roof (most asphalt shingles, concrete or clay tile, and metal qualify; wood shake doesn't), then block embers: vents with 1/16- to 1/8-inch noncombustible metal mesh, enclosed eaves and clean gutters. These steps qualify for insurance discounts under California's Safer from Wildfires program. Get a free estimate.

What makes a vent ember-resistant?

CDI's guidance is noncombustible, corrosion-resistant metal mesh with openings of 1/16 to 1/8 inch over exterior vents, to keep wind-blown embers out (CDI). Listed ember- and flame-resistant vents are another option.

What else on the roof matters?

  • Eaves: enclosing them with soffits keeps heat and embers from getting trapped (CDI).
  • Gutters: keep them clear; leaves and needles ignite from embers.
  • State law: in a very high fire hazard severity zone, replacing more than half the roof requires Class A (HSC 13132.7). Check your zone on CAL FIRE's map.

What's specific to the North Bay?

In unincorporated Sonoma County, Permit Sonoma bulletin B-07 sets Class A roof requirements (Permit Sonoma B-07). The 2017 Tubbs Fire and later fires showed how embers find gaps: vents, gutters full of leaves and old wood shake. A reroof is the natural time to replace eave and ridge vents with ember-resistant ones.
