From plan-stage to certificate of occupancy: dry-in, tile or shingle install, and code-compliant ventilation for Sunnyvale new builds and additions.
New-construction and addition roofing in Sunnyvale lives or dies on coordination. We work to the architect's spec and the GC's schedule — dry-in at the right framing stage so the trades behind us aren't waiting, then the finished system once the building is ready. That means hitting framing-inspection windows, getting ventilation and flashing details right the first time, and leaving a roof that passes Santa Clara County final without a punch list.
Sunnyvale's hot inland summers shape the new-roof spec — proper attic ventilation and heat-tolerant materials so the roof isn't aging from day one under the UV that bakes the region.
Every roof in Sunnyvale answers to the same forces: a Mediterranean, warm and sunny, 15" annual rainfall, and an aging housing stock dominated by Ranch-style, Eichler, tech campus, newer planned communities. The specific local stressors that decide how long a roof actually lasts here: South Bay heat accelerates shingle aging. High UV exposure in this sunnier inland location. Many homeowners combining reroofing with solar panel installation. We've spent enough time on Sunnyvale roofs to know which failure modes show up first, and we plan new roof installation around them rather than discovering them halfway through the job.
That's how we prefer to work on Sunnyvale new builds — we slot into your GC's schedule, dry-in at the right stage, and come back for the finished roof so the project keeps moving.
Yes — additions, ADUs, and dormers are common Sunnyvale jobs. The tricky part is tying the new roof into the existing one watertight; that transition is where we spend the most care.
On a ground-up build the GC usually holds the master permit and we work under it, owning the roofing inspection. On a standalone re-roof or addition we pull the Santa Clara County permit ourselves.
