What's the lay of the land in Ross?
Ross is a small, almost entirely residential town between San Anselmo and Kentfield, with Corte Madera Creek running along its east side and large lots under mature trees. Nearly every home is a detached single-family house.
Does Ross need a Class A roof?
Barely. Our overlay of CAL FIRE's 2025 recommended Local Responsibility Area map on the Census boundary shows Moderate at most inside Ross. Zones change at the parcel level, so confirm yours on the state map before choosing material.
Why are so many Ross roofs coming due?
With a median build year of 1939 or earlier, at typical shingle lifespans a house that age may be on its third or fourth roof. Ross has roughly 728 owner-occupied homes (87% of occupied units), and 98% of its homes are detached houses, according to the Census Bureau's 2024 5-year estimates (Census Reporter).
What kinds of roofs are common in Ross?
Many Ross homes are early-20th-century estates and shingle-style houses with steep, complex rooflines, dormers and chimneys. Those roofs take more flashing, more ridge and valley work and more care with old sheathing than a simple gable, and some are slate or tile that can't be overlaid.
Will Ross's energy code limit my shingle color?
Ross falls in climate zone 2 on the Energy Commission's map (CEC climate zones). Prescriptive cool-roof rules cover steep-slope reroofs only in zones 4 and 8 to 15 and low-slope reroofs in zones 4 and 6 to 15, so they don't apply here. A lighter, reflective product is still an option (CEC).
How does Ross's weather wear on a roof?
The California Energy Commission puts Ross in climate zone 2 (CEC climate zones). At the Kentfield station, NOAA's 1991-2020 normals come to about 44.4 inches of rain a year; 61% of it falls in the three winter months. Heat is moderate, with about 27 days a year at 90 degrees or more. (NOAA normals)
How do Ross's seasons affect scheduling?
June through August average only about 0.41 inches of precipitation combined at the Kentfield station (NOAA), so late spring through early fall is the easy window. Roofers' calendars fill early for that stretch; asking for quotes in late winter or spring gives you the best choice of dates. Winter jobs are possible if the crew dries in each section the same day.
Do I need a permit to replace a roof in Ross?
The Town of Ross lists reroofing as an over-the-counter permit (Town of Ross permit services). If you plan to change the roof material rather than replace it in kind, ask the building department whether design review applies.

Can I get a reroof permit the same day in Ross?
The town lists reroofing among its over-the-counter permits. Your roofer normally applies; a change in roof material may need extra review, so ask before you sign.
Can I get a firm price for a Ross roof without an inspection?
No. A roofer needs to measure the roof, count layers, check the pitch and look at the deck from the attic before a price is firm.
