Custom Trusses for Home Additions in Northern California
Trusses Engineered to Match Your Existing Roof
Adding onto a home means your new trusses need to integrate seamlessly with the existing roof structure. Mike Walker Lumber Co Inc's engineering team designs addition trusses that match your current roof pitch, overhang dimensions, and bearing points — so your framer gets a clean tie-in and your homeowner gets a roof that looks like it was always there.
We handle every type of residential addition: single-story room additions, second-story pop-ups, garage expansions, sunroom enclosures, covered patio extensions, and bonus room additions over garages.
Why Additions Need Engineered Trusses
Many contractors try to stick-frame additions to save cost, but engineered trusses actually save time and money on most addition projects. Pre-fabricated trusses arrive ready to install, eliminating hours of on-site cutting and fitting. They're engineered for exact code compliance, which simplifies your permit process. And they provide consistent quality that stick-framing can't match.
Working with Your Contractor
If you're a homeowner planning an addition, we work directly with your general contractor or architect. If you're a contractor, just send us the addition plans and we'll handle engineering, fabrication, and delivery. We can also visit the job site to field-measure existing conditions when needed.
