New construction and remodel installs across Union City — we coordinate with your GC, hit framing inspection windows, and finish to architect-spec.
New-construction and addition roofing in Union City 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 Alameda County final without a punch list.
Union City'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 Union City answers to the same forces: a Mediterranean, bay-moderated, 18" annual rainfall, and an aging housing stock dominated by Suburban tract homes, newer planned communities. The specific local stressors that decide how long a roof actually lasts here: Bay influence moderates temperatures. Many 1980s–90s homes are reaching reroof time. Some hillside exposure to bay winds. We've spent enough time on Union City 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 Union City 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 Union City 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 Alameda County permit ourselves.
