What We Do

Roofing Services
in Union City

As Union City’s hometown roofer — we’re headquartered on JFK Boulevard — we know every roof along Bergenline Avenue, Summit Ave, and the dense walkup grid down to Palisade. Most are flat: Firestone torch-down modified bitumen, Tri-Built 985 silicone restorations, and emergency leak repair. Shingle work shows up on the few freestanding single-families and exterior siding rounds out the whole-exterior projects. Our 23+ year relationship with Union City’s Construction Code Office on Palisade Avenue means Damian knows the inspectors by first name and permit pulls move in days, not weeks.

Union City Was Built on Flat Roofs

This is Gaby Roofing’s home turf — our shop sits at 4404 Kennedy Blvd — so we’ll say it plainly: Union City is a flat-roof town. One of the densest cities in America fits its people into attached row homes and walkup apartment buildings, shoulder to shoulder from Bergenline Avenue across to Palisade, and nearly every one of those buildings tops out in a low-slope membrane roof. Walk far enough, though, and the pitched roofs appear — and when a Union City homeowner needs shingles, we install the same architectural systems we put on houses across Hudson County: Owens Corning, GAF, CertainTeed, full tear-off every time. Flat roof repair and replacement in Union City, NJ is the core of the business and has been for 23 years, with shingle roofing a strong second. We know these roofs from the inside — the layered old membranes, the tired scuppers, the parapets shared with the neighbor on each side.

Row Homes Wall to Wall: Roofing Logistics and Drainage in Union City

In Union City, the roof work is often the easy part — getting to the roof is the challenge. Buildings here touch on both sides. Side-yard access is rare, rear access rarer, and on plenty of jobs every roll of membrane goes up through the building or over the front face. We plan tear-offs around those constraints: dumpster placement on tight streets, debris chuted instead of carried, neighbors notified before the first torch lights.

Drainage deserves equal attention, because most Union City, NJ flat roofs have almost no pitch. Water that can’t find a scupper finds your ceiling instead. We clear and resize scuppers, add drains where the roof needs them, and use tapered insulation to push water where it should go rather than letting it pond where it shouldn’t.

Shared parapet walls get new flashing tied cleanly into the neighbor’s side, because half the leaks on attached buildings start at that wall. Gaby Roofing has repeated this process on hundreds of local row homes — it’s a system now, not an experiment.

Union City’s tightly-packed row homes share parapet walls with neighbors on both sides, which means staging, scheduling, and tear-off logistics matter as much as the actual roof work. We’ve done several hundred of them. Side-yard access is rare, rear-yard access is rarer, and the freight elevator approach we developed for Bergenline Avenue 4-unit walkups saves at least a half-day per project.

The 25% Rule in Union City

Because Union City’s row homes are old and tightly packed, most of the roofs we open up have a history — layer over layer, patch over patch. That history is exactly what New Jersey’s 25% rule polices.

25%

Once repairs exceed 25% of the roof area in any 12-month period, you’re no longer repairing; you’re replacing — and the full roof must be brought to current code with ice-and-water shield, drip edge, and proper underlayment. The code also limits how many layers can sit on a roof before tear-off is required. A landlord patching a Union City, NJ walkup leak by leak can cross that line without realizing it. We track the math on every estimate and give you the honest call: contained repair, code-compliant replacement, or a silicone restoration in between. Guessing wrong invites failed inspections, pulled permits, and trouble at closing.

For Union City homeowners, this matters because patchwork repairs on an aging flat roof can quickly cross the 25% line. We assess every job up-front and tell you exactly where you stand: small repair, full replacement, or a silicone restoration that rides between the two.

Why it matters: doing this wrong opens you up to permit revocation, failed inspections, and insurance issues at sale time.

Frequently Asked

Roofing FAQ — Union City

A professionally installed torch-down flat roof in Union City will typically last anywhere from 15-25 years depending on drainage, ponding water, sun exposure, and long-term maintenance. Gaby Roofing backs full roof replacement systems with a 10-year workmanship warranty. Since many Union City flat roofs have minimal slope and attached-building conditions, proper drains, scuppers, flashing, and edge details are critical for getting the longest life out of the roof.
Yes. Most full roof replacements and major roofing repairs in Union City require permits through the Union City Department of Building & Construction located at 3715 Palisade Avenue, Union City, NJ (201-348-5753). Gaby Roofing is based in Union City and is very familiar with the local permitting process, inspection scheduling, and township requirements. We handle the permit paperwork, documentation, inspections, and project coordination so homeowners do not have to manage the process themselves.
Flat roof replacement costs in Union City depend on roof size, existing roof layers, access conditions, plywood decking, drainage corrections, and whether insulation upgrades are needed. Many Union City row homes have older roof assemblies, tight access, and minimal slope, so the final scope depends heavily on what is found during the roof inspection. Gaby Roofing provides a detailed written estimate after evaluating the roof in person.
Because Gaby Roofing is located in Union City, emergency leak response can often be very fast for local property owners. We can typically respond the same day or within 24 hours depending on weather conditions and emergency call volume. Emergency service may include leak tracing, drain clearing, temporary waterproofing, and tarping until a permanent repair or replacement can be scheduled. Call 201-638-8556 for emergency roof leak service in Union City.
Attached row homes are one of the most common roofing layouts in Union City. Gaby Roofing plans these projects around tight property lines, front-only access, neighboring buildings, shared parapet walls, and safe material staging. During the roof replacement, extra attention is given to the flashing transitions on both sides of the property so the new roof ties in cleanly without creating water issues at the shared walls.
Many Union City flat roofs have very little slope, which makes ponding water one of the biggest factors in roof life. Before installing a new roof system, Gaby Roofing evaluates existing drains, scuppers, low spots, and water flow direction to determine whether drainage improvements are needed. When necessary, we may recommend tapered insulation, additional drains, larger scuppers, or targeted re-sloping so the new roof is not installed over the same drainage problem that caused the previous roof to fail.
