About This Service

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.

Got Questions?

New Addition Trusses FAQs

01 Can you match trusses to my existing roof pitch?

Yes. We design addition trusses to match your existing roof pitch, overhang, and bearing conditions. The result is a seamless roofline that looks like the addition was part of the original build.

02 Do I need trusses for a small addition?

Even small additions benefit from engineered trusses. They install faster than stick-framing, provide stamped engineering for permits, and ensure structural consistency. For very small projects, we can advise whether trusses or stick-framing makes more sense.

03 How do you handle second-story additions?

Second-story additions require careful engineering to ensure the new trusses properly distribute loads through the existing structure. Our team designs floor and roof truss systems for second-story pop-ups that work with the existing foundation and wall framing.
