Fiber Cement Siding in Kentfield, CA

Why wood fails on these wooded slopes

The original wood siding on Kentfield's mid-century and custom homes was never matched to the climate it sits in. Fog settling under the tree canopy keeps the shaded elevations damp for hours each cool-season morning, and wood that stays wet that long swells, splits at the fasteners, and rots from the back face inward where no one sees it until the sheathing goes soft. Fiber cement is dimensionally stable through that wetting and drying, holds paint far longer in the shade, and will not feed a fire on the parcels nearer the mountain. It reproduces the lap, board, and shingle profiles these homes were built with, so the durable material carries no aesthetic penalty against Kentfield's established character.

The system, not just the board

Fiber cement only earns its reputation in Kentfield when it is installed as a drying assembly. On a slope where moisture comes down with the fog and lingers in the canopy shade, we back the board with a continuous weather-resistive barrier and a vented rainscreen gap so air circulates and the rear face releases what it absorbs. Clearances at grade keep the bottom course off damp soil and leaf litter; kickout and head flashing route roof runoff away from the wall rather than into it. The board itself is inert to the damp, but a tight, unvented install on a fog-shaded north elevation can still trap water against the framing. The detailing is where the longevity lives, and it is what we scope to each elevation's exposure.

Fiber cement on mid-century proportions

Kentfield's mid-century homes lean on horizontal lines, wide reveals, and clean deep-eave geometry, and fiber cement suits that vocabulary well. We can run smooth wide-lap or panel profiles that hold the era's calm, uninterrupted face rather than chopping it up with busy detailing. On the custom homes, the same product range lets us mix lap, board-and-batten, and shingle deliberately to compose more modern elevations against the tree backdrop. Because so many of these lots are viewed through filtered canopy light, the matte, factory-finished surface reads more refined than glossy vinyl ever could. Matching the existing exposure and trim proportion keeps a re-clad Kentfield home looking intentional rather than re-wrapped, while quietly removing the wood's vulnerability to the slope damp underneath.

Cutting and staging fiber cement on a canopy lot

Installing fiber cement on a Kentfield hillside parcel is a logistics exercise as much as a carpentry one. The boards are heavy and ship in long bundles, and many of these lots sit off narrow lanes with short driveways and a real carry up to the wall through trees. We plan the delivery drop, scaffold footing on the grade, and the cut-station location before the first board comes down. That cutting station matters here: silica dust has to be kept out of adjacent windows and away from the mature oak and bay canopy that defines the lot, so we position and shroud it deliberately. On a downhill elevation we sequence the work to dry-in the most exposed faces first, because the fog and slope-driven weather give little margin for an open wall.
