Fire-Resistant Siding in Stinson Beach, CA

Two fire realities in one small town

Most cities we serve have a single fire profile; Stinson has two. Out on the sandspit and at Seadrift, surrounded by sand, surf, and the lagoon, the direct wildland fire threat is low — there is simply little vegetation upwind to carry a fire to the wall. We say that plainly rather than overselling a fire upgrade those homes do not need. The hillside homes are the opposite: the steep, vegetated Mt. Tam slope rises right behind them, and a wind-driven ember run off that wildland edge is a credible event. For those lots, non-combustible Class A cladding and a hardened envelope are a sound, measured response. Matching the fire spec to the actual lot is the whole discipline here.

On the Mt. Tam slope, the wall is a system not a face

For the hillside houses, choosing a Class A cladding is only the start, because embers do not respect the wall plane. Non-combustible board paired with open eaves, unscreened vents, or a wood-to-grade transition leaves the obvious gaps that ember intrusion exploits. So on a slope lot near the wildland edge we treat eaves, soffit and foundation vents, and the ground-contact zone as part of the same scope — closing the underside of eaves, fitting ember-resistant venting, and detailing the spots where siding meets soffit, deck ledger, and foundation as ignition points rather than trim. On the older cottages climbing the hill those transitions were often left vented or loosely flashed, so a re-side is the moment to correct them and make the finished exterior read as one continuous defensive layer.

Defensible space and ember basics for the beach flats

For the sandspit and Seadrift homes where direct wildland threat is low, the honest advice is not a heavy fire-rated re-side but the inexpensive basics that matter even in lower-exposure settings. Embers travel, and a non-combustible cladding still adds value as a wall that will not contribute fuel if a neighboring structure ignites in a dense beach-cottage cluster. We focus those projects on the cheap, high-value moves: keeping combustible debris off decks and out of the zone right against the wall, screening vents, and choosing a Class A board so the house is not the weak link in a tightly packed row. That is a measured, proportionate position — we do not dress up a flat beach lot as if it sat in the canyons of Mill Valley.

Fire-rated and salt-proof have to be the same wall

What makes Stinson different from a dry inland fire town is that the fire-resistant assembly still has to survive extreme oceanfront salt and marine damp. A Class A non-combustible surface resists fire, but it is not the corrosion-control or moisture-control layer, and a fire upgrade that ignores the salt simply trades a wildfire risk for a rust-and-rot one. So even the hardened hillside walls get marine-grade fasteners, corrosion-rated flashing, and a drained, back-ventilated rainscreen so the assembly can dry between fog cycles. The goal on a Stinson home is a single wall that does both jobs at once — sheds embers on the outside and manages open-Pacific salt moisture behind it — rather than a fire spec that quietly corrodes its way to a short life on the coast.
