Tri-City Roofing serves Union City — Decoto, Alvarado, and the New Haven areas — with roof repair, reroofing, and maintenance. Much of Union City is 1960s–70s tract housing on the bay flats, where low-slope roofs and wind exposure create their own recurring roofing issues. We know these homes.

Roofing in Union City
Union City sits on open bay flats, so wind is the defining factor — it lifts shingle edges and drives rain under flashing. Many roofs are low-slope, where standing water and blocked drains cause slow leaks that go unnoticed until they reach the ceiling. We check drainage and wind-vulnerable details first. Permits go through the City of Union City.

Union City Roofing FAQ
Why do roofs in Union City lose shingles so often?
The open bay flats leave roofs wind-exposed. We repair and re-secure wind-vulnerable edges and can upgrade to higher wind-rated materials on a reroof.
Do you handle low-slope / flat roofs?
Yes — repair and replacement of low-slope roofs, including drainage fixes that prevent standing water.
