Fast, Reliable Roofing Across Union City
When your roof starts leaking on a windy January night off San Francisco Bay, you don’t want a call center in another state. You want someone who knows that Union City’s flatland homes face a different set of problems than the hill homes in Fremont. We’ve been answering our own phone since 1998, and a live person picks up 24/7 at (877) 610-1318. Tom Barrett and his sons run the crews that serve our Union City service area directly, not a rotating cast of subcontractors. We’re here for everything from a small leak near Decoto to a full tear-off on a 1960s tract home near Alvarado.
Why Barrett & Sons Construction Is Union City’s Preferred Roofing Company
Most Union City homeowners we meet have already been burned once by a national outfit that quoted one price on the phone and handed them a different bill at the door. That’s not how we work here. Every price change at Barrett & Sons arrives as a written change order before a single nail moves. We pull permits and schedule inspections on every eligible job because we know Union City’s building department requires them. And when the job’s done, the 90-Day Done Right Promise is written on your contract: if something isn’t right, Tom comes back and fixes it, one call.
Our Roofing team works throughout Union City, from the older Decoto and Alvarado districts to the newer subdivisions east of Union City Boulevard. We know which homes were built on bay fill and need extra attention to flashing and underlayment. We know which ones predate modern seismic codes and may need sheathing upgrades once we pull back the old shingles. That local knowledge means our estimates are realistic from day one, not optimistic guesses meant to win a deposit.
We’ve been owner-operated from day one. You’ll see Tom or one of his sons on your roof, not someone who showed up from three counties away. Our crew members are background-checked and carry the Barrett & Sons name on their shirts. If you want to check us out before you call, Tom’s name, address, and license number are published for anyone to verify.
Our Roofing Services in Union City
Roof Repair
Union City’s delta winds off the bay drive moisture hard into exterior assemblies. We regularly find failing flashing at chimneys, pipe boots, and valley transitions on 1960s and 70s tract homes. A typical roof leak repair in Union City runs $400-$1,800 depending on what we find once we open it up. We’ll show you photos of the damage before we touch anything, and the fix gets a written scope before work starts.

Roof Replacement & Installation
Most Union City single-story stucco homes built between 1959 and the mid-1970s are approaching the end of their second or third roof’s life. A full roof replacement in Union City typically falls between $8,000-$20,000, with material choice and decking condition driving much of that range. We install GAF and CertainTeed shingle systems backed by manufacturer warranties, and we handle the Union City permit and inspection process from start to finish.

Metal Roofing
For Union City homeowners looking to stop the replacement cycle once and for all, standing seam metal roofing is a serious option. It handles the bay-driven wind and rain better than anything else we install, and it sheds the kind of wind-blown debris that bangs around flatland yards during fall storms. Expect a metal roof installation in Union City to run $15,000-$40,000. It’s not cheap, but it’s often the last roof you’ll ever buy.

Tile Roofing
Tile roofs are less common in Union City’s mid-century tract stock, but we do see them on newer custom homes and on repairs for barrel tile installations in the hillside transition zones toward the Hayward border. Tile roof repair in Union City typically lands between $600-$2,500 depending on the number of broken or slipped tiles. Walking a tile roof wrong causes more damage than it fixes, which is why we lay out our access plan before anyone goes up.

Trusted Brands We Service in Union City
We install and service roofing systems from GAF and CertainTeed because those are names you can verify without taking our word for it. When your Union City home needs a repair that matches existing Simonton windows or doors in the envelope, we coordinate that work too, including Driveway & Pavers in Union City. The point is simple: we don’t put mystery materials off a van on your roof. If a brand has a documented performance record, we’ll stand behind it. If it doesn’t, it doesn’t go on your house.
Common Roofing Problems We See in Union City Homes
- Wind-driven leaking at eaves and rakes. Diablo winds off the bay push rain sideways, which finds every gap in aging fascia and drip edge. We see this most often on the 1960s-era subdivisions west of Union City Boulevard where original flashing has thinned and pulled away.
- Moisture intrusion at penetrations. Pipe boots, vents, and chimney flashing degrade faster here because of year-round bay humidity and salt air. On older Decoto-area homes, we regularly find decking rot hidden under shingles that looked fine from the ground.
- Premature shingle granule loss. Flatland Union City homes catch full bay wind without hillside tree cover to slow it down. That constant abrasion strips granules off shingles faster than you’d see in Fremont’s sheltered canyons, shortening the effective life of a standard architectural shingle.
- Seismic-related stress at roof-to-wall connections. Pre-1970s tract homes weren’t built with the hold-down hardware modern codes require. Movement during the Alameda County seismic events we occasionally feel can open hairline cracks that let water in slowly, which is why we check the roof-to-wall transition on every older Union City home we walk.
