Two fire standards, one hillside: which one applies to your roof
Kensington's fire district says the community lies in a Very High Fire Hazard Severity Zone and asks for a minimum Class B roof when you build or re-roof. State law reads more strictly: a Class A covering is called for when more than half the roof is replaced within a year in such a zone. The two do not line up, so a Class B choice can fail the state test.
We recommend asking the fire district and Contra Costa County which standard they enforce at your address, and pricing Class A either way. A Class A rating describes the whole assembly, covering and underlayment together, and we name the assembly in the quote. CAL FIRE's viewer shows the parcel's zone.


Roofing services for Kensington hillside homes
- Roof Repair
Hillside roofs from the mid-century decades usually fail at flashing and vents first, and a repair can hold a sound covering, with a safe-access plan made before the crew climbs.
- Roof Replacement
A Kensington replacement starts with the fire-rating question, then layers, decking and slope access, with Contra Costa County confirming the permit for this unincorporated address.
- Gutters
Steep roofs shed water quickly, and gutters on a bay-view slope need strong hangers and a downspout path that does not undercut the lot below the house.
- Emergency Roof Repair
A hillside leak gets temporary protection with a safe-access plan first, because the fall risk is higher than on flat ground, and the permanent fix waits for a dry roof.
- Storm Damage Roofing
Wind and branch damage hit exposed slopes first in winter, and storm repairs are photographed and written up in a scope that the Kensington owner or an insurer can follow.
- Roof Flashing Repair
The Hayward Fault runs along these hills, so chimney bases, step flashing and ridge lines are checked for cracks after a notable shake, before the next storm tests them.
- Roof Inspection
Because two fire standards apply to a Kensington roof, an inspection with photos records the current covering and layers before you ask the fire district and the county what they enforce.
Steep lots and bay-view slopes
Kensington's lots climb steeply, and many houses sit well above the street. Access shapes the schedule: where the truck stops, how bundles get up the driveway, and where debris is caught. Workers use fall protection, and we haul debris daily.


The Hayward Fault runs along these hills, so after a notable quake check chimney bases, flashing and ridge lines for cracks. Our storm damage page covers wind and branch damage, which hit exposed slopes first.
County permits above a city
Contra Costa County issues permits in Kensington, while the lower city of El Cerrito runs its own building office. The line is easy to miss, so give us the street address and we help sort out who files. Nearby pages cover El Sobrante, San Pablo, Albany and Berkeley. The estimate states who pulls the permit.
Visiting from Alameda
The office lines up the visit, and Wayne or Pedro often handles the inspection. It is about 27 minutes in light traffic. A detailed written quote comes first, texts and emails with photos arrive during the work, and a site supervisor does the last walkthrough.
We claim no Kensington job. Read the warranty terms in your contract before signing, and ask us anything unclear.
Call before the first rains if the roof is due, because hillside access takes extra planning.
