Composition shingle, concrete tile, standing-seam metal, and low-slope flat assemblies — installed to the manufacturer's spec, not improvised on the roof.
Every roofing system has a right way to go on a Union City roof and a dozen wrong ones. Composition shingle, concrete and clay tile, standing-seam metal, and TPO/EPDM flat assemblies each need a specific substrate, fastener pattern, and ventilation profile to actually earn the manufacturer warranty. We install the system you choose the way the spec — not the shortcut — requires, which is the difference between a roof that hits its rated life and one that fails early.
On Union City roofs the conditions that matter most — Bay influence moderates temperatures. Many 1980s–90s homes are reaching reroof time. Some hillside exposure to bay winds. — are what we plan the work around, not an afterthought.
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 shingle, tile, metal & flat roof systems around them rather than discovering them halfway through the job.
All the major ones — composition/asphalt shingle, concrete and clay tile, standing-seam metal, and flat-roof membranes (TPO, EPDM). The right pick for your Union City home depends on pitch, exposure, structure, and how long you plan to keep the house.
Asphalt is lighter, cheaper, and fine for most Union City homes at 25–30 years on an architectural shingle. Tile lasts 40–50 but needs the structure to carry the weight. We'll tell you honestly which your home is built for.
Yes. If your Union City property sits in a Wildland-Urban Interface zone, the assembly has to be Class A fire-rated — that narrows the material choices, and we build to that standard where code requires it.
