Which roofing materials are Class A?
Per the CDI, most asphalt shingle roofs, concrete, brick or masonry tile, and metal shingles or sheets qualify as Class A. Wood shake shingles do not. Confirm the specific product's listing.
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?
Three more details: soffits over open eaves (CDI), gutters cleared of leaves and needles (or noncombustible guards), and the legal floor, Class A on qualifying reroofs in very high hazard zones (HSC 13132.7; find your zone).
What's specific to the East Bay?
Berkeley adopted a Wildland-Urban Interface chapter in 2025 for homes in its fire zones (Berkeley WUI code), and the Oakland hills, where the 1991 firestorm destroyed thousands of homes, remain one of the region's best-known fire areas. Hill homes in Orinda, Lafayette and Moraga along open space face similar ember exposure.

Do ember-resistant vents reduce airflow?
Fine mesh can, so roofers may add vent area. Ask how they keep ventilation adequate.
Should I enclose my eaves?
The CDI recommends it, with noncombustible or ignition-resistant materials.
