Fast, Reliable Roofing Company Across Union City
Roofing work in Union City usually runs between $8,500 and $22,000 for a full replacement, while repairs on original 3-tab shingles typically cost $425 to $1,100 depending on how far moisture has traveled under the decking. Those numbers come from the homes we see every week in Decoto, Alvarado, and the Ranch-style tracts east of Alvarado-Niles Road. If you’re reading this because a leak is dripping into a bedroom or because you spotted curling shingles from the sidewalk, call (945) 303-9821 and we’ll give you a written quote before any work begins.
What makes a Roofing Company in Union City different from an inland operation is knowing the bay. This city sits low, close to the water, with salt-laden marine air pushing in from the South Bay. That changes everything about how shingles age, what fails first, and what should go back on the roof. We plan for it. Our crews work the same streets you drive, and we scope every job based on what Union City’s climate actually does to a roof, not a generic checklist from somewhere drier.
Why Tilehurst Roofing Is Union City’s Preferred Roofing Company
Tilehurst Roofing is a Kingswell family company, founded in 2000, and independently owned and operated under the Kingswell Guarantee. Greg Holloway leads the team that serves Union City, and the rules he runs on are simple: say the price before the work, show up in the window we gave, leave the property cleaner than we found it, put the guarantee in writing, and come back if it fails. Those five practices make up what we call The Kingswell Way, and they’re why homeowners who have been burned by no-shows or door pricing call us instead.
Every repair carries a written guarantee, delivered before the crew leaves, not mailed later. That guarantee sits inside the 365-Day Done Right Promise, which covers a full year of documented accountability. If a repair fails within that year, we return and correct it at no charge. No fine print about “normal wear.” No “that’s not covered.” The guarantee states exactly what is covered and for how long, in plain language, on the day the work finishes.
Our Roofing Company team fields calls from Union City homeowners who have dealt with a roofer who never showed, or who showed, looked around, and added $1,800 to the number before opening the truck. That does not happen here. We hand you a written price before any work starts, and we do not negotiate away the line items that protect the roof. You know the cost of the decking, the underlayment, the flashing, and the shingles before the tear-off begins. That is not a premium feature. It is the floor.
Background-checked, uniformed technicians work on your roof. You know who is on the property, and you know they are accountable to a local operation that will answer the phone without a callback queue or voicemail. A live person answers every call, 24 hours a day, 7 days a week, including evenings and weekends.
Commercial Roofing in Union City
Commercial Roofing in Union City means protecting low-slope buildings lining Alvarado-Niles Road, the light-industrial perimeter east of Union City Boulevard, and the strip centers scattered among the residential tracts. A commercial roof here fails by ponding water and hidden seam separations, not by shingle curling. Water sits longer on low-slope decks in this marine-influenced climate, and once it finds a path through a failed seam, it travels sideways under the membrane before anyone sees a stain on a ceiling tile. Most flat and low-slope commercial repairs in Union City run $1,200 to $4,800, depending on the membrane type and how far the water has spread beneath it.
We scope commercial work differently than residential. We start with the drainage, because a roof that holds water will fail again no matter what membrane goes on top. We check the condition of the edge metal, the penetrations, and the transitions from roof to parapet, then we give a written number for the repair before any work starts. The Kingswell Guarantee applies here exactly as it does on a home: if the repair fails inside the guarantee period, we return at no charge.
Low-Slope Restoration and Coating
Older built-up and modified-bitumen roofs on Union City strip centers often reach a point where full replacement is not necessary, but the aging membrane needs reinforcement before rainy season. A restoration coating over a structurally sound deck can add 10 to 15 years of service at roughly $6 to $9 per square foot. We inspect first, document what is sound and what is not, and quote honestly whether a coating will hold or just postpone the inevitable.
Tenant Improvement and Roof Access
When a retail or office tenant replaces HVAC units or adds exhaust fans, the roof penetrations need to be sealed correctly or the building leaks within months. We handle the roof-side portion of these upgrades, making sure new curbs, flashings, and pipe boots are installed to manufacturer spec and tied into the existing membrane. The goal on a commercial job is the same as residential: a written price, a documented scope, and a roof that stays dry past the warranty date.
Metal Roof Installation in Union City
Metal Roof Installation in Union City answers the city’s most persistent roof problem: moisture. Standing seam and metal shingle systems shed water and resist the algae and moss that colonize composition shingles in bay humidity. A metal roof here typically runs $18,000 to $38,000 for an average tract home, with the final number driven by roof complexity, panel profile, and whether the existing roof layer comes off first. Metal is not the budget choice, but for a homeowner planning to stay in the house for 20 years, it is often the last roof they buy.
We install standing seam and metal shingle systems, always over the correct underlayment for a marine climate. Salt in the air is hard on fasteners and exposed metal edges, so we spec marine-grade or coated fasteners and never cut corners on trim. The roof needs to breathe and drain, and metal does both well when the details are right. That is the kind of thing a Union City homeowner gets by working with a local team that has done this work on the same housing stock for years.
Standing Seam vs. Metal Shingle
Standing seam panels run vertically from eave to ridge and hide all fasteners behind raised seams. They are the best choice for low-slope and medium-slope roofs common on 1960s ranch homes. Metal shingles look more like traditional roofing from the street but still carry the corrosion resistance and longevity of steel. We walk through both options before quoting, and the written price covers whichever system you select, with no change order for a standard roof shape.
Underlayment and Marine Air Protection
Union City’s salt-laden air corrodes ordinary exposed fasteners faster than inland cities see. We use high-temp ice and water shield in valleys and eaves, a synthetic underlayment rated for coastal environments, and fasteners with a corrosion-resistant coating. On a roof that stays damp from fog and condensation long after rain stops, these choices add years of service. They are not optional upgrades on a metal roof in this city.
Trusted Brands We Service in Union City
We carry and install systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That is seven manufacturers, which means the roof we quote is selected to fit your home and Union City’s climate, not whatever happens to be sitting in the truck. For homeowners here dealing with algae streaking on north- and east-facing planes, GAF’s Timberline HDZ and CertainTeed’s algae-resistant lines perform well in bay humidity. For those asking about heavier tile, Boral and Atlas both manufacture concrete tile profiles that we can quote once the structure passes a dead-load check. Local parts procurement for Union City customers keeps replacement materials close by when a storm damages a roof and a fast repair is needed.
Common Roofing Company Problems We See in Union City Homes
- Algae colonization on north and east planes. Year-round bay humidity, not rainfall, feeds the dark streaking that spreads across composition shingles on the shaded sides of Union City homes. It is cosmetic at first, but the same moisture attacks the shingle mat and shortens the roof’s functional life.
- Hidden rot on original tract-home decking. Homes built from the 1960s through the early 1980s often have first-generation composition shingles still hanging on over plywood decking that has been wet longer than the homeowner realizes. A tear-off frequently reveals soft spots that cannot be seen until the shingles come off.
- Undersized or missing drip edge on low-slope gables. The low-slope gable roofs common in Union City’s post-incorporation tracts often lack proper drip edge, which lets water wick under the shingle edge and into the fascia. We see the rot pattern at the eave repeatedly in neighborhoods like Decoto and the tracts off Smith Street.
- Flat additions over Alvarado and Decoto bungalows. Older, pre-WWII homes in the historic neighborhoods carry low-slope built-up sections over later additions that often have no underlayment and failing seams. Water hides there for years, and the damage shows up as a stain on an interior wall long after the active leak started.
Pricing for Roofing Company in Union City, CA
A typical asphalt shingle roof replacement on a 1,200 to 1,800 square-foot Union City tract home runs $9,500 to $16,000. The lower end covers a straightforward tear-off and replacement with a dimensional shingle over structurally sound decking. The higher end covers rotten decking replacement, added ice and water shield in low-slope valleys, upgraded drip edge, and ridge vent installation. Metal roofing starts around $18,000 and climbs into the $30,000s for complex roof shapes, and concrete or clay tile runs $22,000 to $42,000 once the structure passes a dead-load check. What changes the price most in Union City is the condition of what is under the shingles, and that is why we inspect before we quote, not after. Call (945) 303-9821 for a free written estimate, no obligation and no number that changes at the door.
We also pull permits and ensure the work passes inspection before we call the job done. The Kingswell Guarantee covers the work in writing, and the 365-Day Done Right Promise holds us to it for a full year. That is how Greg Holloway and the team operate, and it is the reason homeowners in Union City call.

FAQs About Roofing Company in Union City
Union City roofs fail from moisture, not heat. The city’s low-lying bay-front position keeps relative humidity high year-round, producing persistent algae streaking and moss growth on north- and east-facing planes even when it rarely rains. Inland cities like Fremont’s Warm Springs corridor and the Tri-Valley see more thermal cracking and curling from summer heat. Here, moisture infiltration and biological growth attack the shingle mat and the decking beneath, which is why our inspections prioritize ventilation, underlayment condition, and algae-resistant product selection over heat-related shingle failure.
The consequence is that a roof that looks simply “old” in Union City often has hidden rot below the shingles, especially on original 3-tab systems installed in the 1960s and 1970s. When we quote a replacement, we include decking inspection in the written scope because we know what lives under these roofs. Call (945) 303-9821 and we will explain what is happening on your specific roof.
Maybe, but the structure must be checked first. Concrete and clay tile add significantly more weight than the lightweight composition shingles originally installed on Union City’s tract homes, and the Hayward Fault trace runs along the base of the hills directly east of the city. That puts most of the city’s housing in a seismically sensitive zone, which makes the dead-load question more urgent here than in cities farther from an active fault. We walk through the structural verification before any tile project starts, and the written quote includes what the roof can support, not just what the homeowner wants installed.
If the structure checks out, we quote tile from Boral or Atlas. If it does not, we tell the homeowner straight and offer options like architectural shingles or standing seam metal that deliver long life without the structural strain. For an exact number on tile for your Union City home, call (945) 303-9821.
Dark algae streaking that returns after cleaning, curling or lifting shingle edges at the eave, soft or stained decking visible in the attic, and granules collecting in gutters and downspouts. On the low-slope gable roofs common to Union City’s post-incorporation housing wave, persistent streaking on the north and east planes is an early warning. The same moisture that feeds the algae is attacking the shingle mat, and by the time the shingles look clearly failed, the decking underneath usually needs attention too. We offer a free inspection that ends with a written report and a written price for any work needed. Call (945) 303-9821 to schedule one.
Yes. We handle full roof replacements, repairs, inspections, metal roofing, tile roofing, and flat roofing for Union City homes, and we also handle commercial low-slope and flat roof work along Alvarado-Niles Road, Union City Boulevard, and the light-industrial perimeter. Commercial roofing here involves membrane systems, edge metal, drainage corrections, and penetration sealing, and the same written pricing and Kingswell Guarantee apply. If you own a building or manage a property in Union City, call (945) 303-9821 and ask for a scoping visit. We will give you a written number before any work starts.
Metal roofing shrugs off the moisture that destroys composition shingles. Standing seam and metal shingle systems do not support the algae and moss growth that Union City’s year-round humidity feeds, and properly coated steel panels resist the salt in the marine air far longer than asphalt shingles hold their granules. Metal also sheds water fast on the low-slope rooflines common to 1960s and 1970s tract homes, where runoff is already working against the homeowner. It costs more up front, usually $18,000 to $38,000 for an average Union City home, but for a buyer planning to stay 20 years, it is often the last roof that home needs. We quote standing seam and metal shingle systems with underlayment and fasteners rated for coastal exposure. Call (945) 303-9821 for a number specific to your roof.
