What should Kentfield homeowners know before replacing a roof?

What's the lay of the land in Kentfield?

Kentfield is unincorporated, so Marin County, not a town, handles its permits. It runs from the flats around College of Marin up wooded slopes toward Mount Tamalpais, and much of the hillside is State Responsibility Area, where CAL FIRE rather than a city sets the fire hazard zone.

What do wildfire maps mean for a Kentfield roof?

CAL FIRE's 2025 recommended Local Responsibility Area map and its 2024 State Responsibility Area map rates parts of Kentfield Moderate, with no High or Very High ground inside the boundary by our overlay. Check your exact address on CAL FIRE's hazard map; boundaries can split a street.

What housing does a Kentfield roofer work on?

Kentfield's median home was built in 1956, and at typical shingle lifespans a house that age may be on its second or third roof. Census estimates count about 2,187 owner-occupied homes (81% of occupied homes), and 89% of all homes are detached single-family houses (ACS 2024 5-year: B25035, B25003, B25024).

What surprises turn up on older Kentfield 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).

How does Kentfield's weather wear on a roof?

The California Energy Commission puts Kentfield in climate zone 2 (CEC climate zones).

How wet does Kentfield get?

Kentfield is home to a long-running NOAA weather station, and it is one of the wettest in the Bay Area: 44.4 inches of precipitation a year on the 1991-2020 normals, about 61% of it falling in December, January and February. Roofs here get long soaking stretches, so underlayment, valley metal and gutter capacity matter as much as the shingle.

Do Title 24 cool-roof rules apply in Kentfield?

No, not as a prescriptive rule. The Energy Commission puts Kentfield 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.

Do I need a permit to replace a roof in Kentfield?

For unincorporated addresses, Marin County treats a reroof as a self-service maintenance permit on its online portal. Your roofer applies and books the inspections; confirm your parcel is unincorporated before assuming the County is the right office.

Should I wait for summer to reroof in Kentfield?

In Kentfield, the dry season does most of the scheduling for you: summer rainfall at the Kentfield station totals roughly 0.41 inches across June, July and August (NOAA normals). If your roof is leaking now, a temporary repair can carry it to the dry months, but don't wait until the first fall storm to call.
