What should Fairfax homeowners know before replacing a roof?

What's the lay of the land in Fairfax?

Fairfax is the last town up the Ross Valley before open space takes over toward White's Hill and the Mount Tamalpais watershed. Many streets wind up narrow canyons, and the town's housing is among the oldest in Marin.

How does Fairfax's weather wear on a roof?

The California Energy Commission puts Fairfax in climate zone 2 (CEC climate zones). NOAA's 1991-2020 normals for the Kentfield station show about 44.4 inches of precipitation a year, 61% of it in December, January and February. Heat is moderate, with about 27 days a year at 90 degrees or more. (NOAA normals)

What surprises turn up on older Fairfax roofs?

Houses this age often hide surprises. California's code doesn't allow a new roof over two or more existing layers (CRC R908), so many jobs start with a full tear-off. On homes built before 1978, contractors who disturb painted trim or fascia must follow EPA's lead-safe rules (EPA RRP), and old roofing that tests positive for asbestos falls under Bay Area Air District notification rules (BAAQMD).

Do Fairfax's trees affect my roof?

Fairfax roofs live under bay laurel, oak and redwood. Leaf litter holds moisture, so expect moss, rotten fascia and soft decking where valleys stay wet. On a wood shake roof, that wetness speeds decay, and a replacement is also the moment to move to a Class A product.

How do roofers work on Fairfax's hillside lots?

Narrow, steep streets with little parking are normal in Fairfax's canyons. Before quoting, a roofer should look at where a dumpster can legally sit, whether material has to be carried or hoisted from the street, and how the crew will protect a neighbor's driveway. Ask the town whether the bin needs an encroachment permit if it goes on the street.

What do wildfire maps mean for a Fairfax roof?

CAL FIRE's 2025 recommended Local Responsibility Area map shows High as the top class inside Fairfax, with no Very High ground, by our overlay on Census boundaries. The state's Class A reroof rule is tied to Very High zones (HSC 13132.7), but your town can set stricter local rules. Look up your parcel on CAL FIRE's map.

Do Title 24 cool-roof rules apply in Fairfax?

No, not as a prescriptive rule. The Energy Commission puts Fairfax in climate zone 2 (CEC climate zones), outside the zones where a home reroof must use a rated cool-roof product (steep-slope zones 4 and 8 to 15, low-slope zones 4 and 6 to 15). You can still choose a reflective product; see the CEC cool-roof guide.
