Does my Marin home need a Class A roof?

Short answerIf it's in a mapped very high fire hazard severity zone, a replacement covering more than half the roof must be a Class A assembly under state law. Many Marin hill and wildland-edge addresses are mapped. Check the 2025 state map, read FIRESafe MARIN's guidance, and confirm with your town or the County.

Every roofer we work with is licensed, insured and highly reviewed by Bay Area homeowners.

Is all of Mill Valley a fire zone?

Zone lines follow terrain, not town limits. Check your exact address on the 2025 map.

Is a shake roof allowed on a Marin reroof?

Wood shake isn't Class A. In mapped very high zones, a majority replacement must be Class A.
