Siding in Santa Rosa, CA

Rebuild standard vs. hardening older stock

Post-fire Santa Rosa rebuilds are frequently already non-combustible. The biggest gains now are on surviving and older hillside and tract homes still wearing wood, T1-11, or hardboard — where re-cladding delivers both the hardening and the moisture-durability upgrade in one project.

Fire and moisture, designed together

We don't trade one risk against the other. Santa Rosa assemblies pair Class A non-combustible cladding with a rigorously detailed, drying-capable drainage plane — the hillside fire strategy and the North Bay moisture strategy resolved in a single envelope.

Working a re-side on the Fountaingrove ridgelines

The grade is half the job on the eastern hills. Fountaingrove and the slopes climbing toward the Rincon Valley line put crews on cut-and-fill lots where one elevation faces a downhill drop and the wind funnels uphill through the canyon in the afternoon. That changes how a Santa Rosa re-side is staged. Scaffold has to be tied and leveled on a slope rather than set flat, material gets walked rather than craned to the high gables, and the downslope wall is usually the most exposed face we detail first. Established in-town and east-side homes off Sonoma Avenue are gentler ground, but the older lots come with mature oaks crowding the eaves and tight side yards that limit how much board can be staged at once. We size the staging plan to the lot before quoting, because a steep Fountaingrove parcel and a flat Rincon Valley street are genuinely different days of labor even when the wall area matches on paper.

What the WUI map does to your wall assembly

Much of Santa Rosa east and north of Highway 12 sits inside a mapped wildfire-urban-interface zone, and that designation drives the siding spec long before anyone picks a color. In those areas we build toward an ignition-resistant exterior: non-combustible cladding such as fiber cement or mineral-faced board, backed by attention to the parts that actually catch a fire, the soffits, the open eaves, and the vent screens where embers collect during a wind-driven event like the one that crossed the city in 2017. A re-side here is really a chance to close those gaps while the wall is already open. We also keep the bottom course detailed away from bark mulch and fence returns so a ground ember has nowhere to climb. Neighboring communities like Sonoma and Sebastopol share the same interface logic on their hill edges, so the approach is consistent across the area, but Santa Rosa's recent burn history means homeowners here tend to want the hardening done thoroughly rather than to the minimum the map allows.
