From plan-stage to certificate of occupancy: dry-in, tile or shingle install, and code-compliant ventilation for San Francisco new builds and additions.
New-construction and addition roofing in San Francisco 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 San Francisco County final without a punch list.
San Francisco's wind exposure drives the fastening schedule and edge detailing on a new install — we build the wind resistance in at framing, where it's permanent and invisible.
Every roof in San Francisco answers to the same forces: a Coastal fog, cool summers (55–65°F), wet winters with 20" annual rainfall, and an aging housing stock dominated by Victorian, Edwardian, Mid-Century Modern, high-density flat-roof condos. The specific local stressors that decide how long a roof actually lasts here: Persistent marine fog and moisture accelerate granule loss on asphalt shingles. High winds in exposed neighborhoods like Twin Peaks and the Outer Sunset require secure fastening patterns. Salt air near the bay accelerates metal corrosion without protective coatings. We've spent enough time on San Francisco 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 San Francisco 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 San Francisco 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 San Francisco County permit ourselves.
