Walnut Creek's Trusted Truss Manufacturer for Rossmoor & Beyond
Walnut Creek is anchored by Rossmoor — one of the West Coast's largest 55+ communities and a near-perfect analog to the Sun City work Walker Lumber runs in Sacramento metro. Truss replacement, re-roofing, aging-in-place ADU additions, and 1960s-70s stock upgrades make up the bulk of Walnut Creek work, and our 65-mile run down I-680 is a same-day delivery from North Highlands.
Who Walker Lumber serves in Walnut Creek
Walker Lumber has been supplying truss packages to Walnut Creek builders, framers, GCs, and developers for years. Rossmoor and the surrounding Rossmoor (55+), Northgate, Saranap, Parkmead neighborhoods generate steady re-roof, ADU, and aging-in-place work — many on the exact same 1960s-70s truss profiles Walker has been engineering and replacing in Sun City Sacramento for decades. Every package ships on one truck with one driver and an engineering stamp that's known to your local plan-check.
Walnut Creek building conditions that affect truss design
Diablo wind events on the east flank of Mt. Diablo create localized high-wind exposure, especially in upper Saranap and the Mt. Diablo edges. Truss-to-wall hold-downs and uplift detailing on those sites reflect ASCE 7 wind requirements. Seismic Design Category D/E applies in Walnut Creek — both the Calaveras and Concord faults run through Contra Costa and Alameda counties, and we spec lateral connectors, bracing, and hold-downs to ASCE 7 code accordingly.
Why Walnut Creek builders pick Walker Lumber
Rossmoor 55+ community parallels Sun City Sacramento, aging-in-place ADU work, Diablo wind exposure. That's the short version.

Truss types we supply for Walnut Creek projects
Every Walnut Creek project gets a truss package engineered from scratch — span, pitch, lumber grade, plate sizing, and connector schedule all reviewed against the loads your jobsite actually sees. Here's what we manufacture and ship to Walnut Creek:
Residential roof trusses
Common gable, hip, scissor, and vaulted roof profiles for single-family homes in Walnut Creek. Our shop fabricates the full range — from standard production trusses for tract subdivisions to one-off engineered profiles for custom builds. Engineered to the ASCE 7 wind and seismic loads Walnut Creek plan-check expects.
Floor trusses
Our floor trusses ship in standard or custom depths, with the open-web design framers prefer for fast trade rough-in.

Rossmoor and the surrounding 55+ community generates steady aging-in-place ADU work, often paired with single-story re-roof projects on the main home. We engineer ADU truss packages from garage conversions to detached two-story units on lot splits, with standard residential pricing — no premium for ADU-scale jobs.
