Flat Roofing Is What We Do

Hudson County is dominated by flat-roof housing — Hoboken brownstones, Union City row homes, Jersey City multifamilies, North Bergen hilltop properties, and the warehouses of Bayonne and the Tonnelle corridor. We’re a flat-roof specialist, which means flat roofs aren’t a sideline for us — they’re the bulk of every week’s work, every month, every year for the last 20+ years.

Replace or Restore?

Two Flat Roof Systems We Install

Most Hudson County flat roofs end up choosing between full torch-down replacement and silicone restoration. The right answer depends on the existing roof’s condition, age, and ponding patterns. Here’s how each system compares.

Modified Bitumen Torch-Down

Full Replacement System

SBS-modified asphalt membrane heat-welded to the deck with propane torches. The full-replacement choice when an existing roof has reached end-of-life, has substrate damage, or has too many existing layers.

  • Long-term service life
  • 10-year Gaby Roofing-backed warranty
  • Class A fire rating
  • Best for end-of-life roofs

Silicone Restoration Coating

Restoration Without Tear-Off

High-solids silicone coating bonded directly over an existing modified bitumen, EPDM, or BUR roof. Roughly half the cost of full replacement, with a seamless waterproof finish that handles ponding water.

  • 10–15 year service life
  • Reflective Energy Star finish
  • Seamless waterproofing
  • Best for sound aging roofs

25% Rule

Repair, Restore, or Replace? The 25% Rule.

NJ’s reroofing code limits how many roofing layers can stack — and how much repair work you can do before the entire roof must come up to current code. The 25% rule is the threshold where small repairs cross over into a full-replacement obligation.

For Hudson County flat roof owners this matters because patchwork repairs on aging modified bitumen quickly add up. A few small leaks today, a parapet flashing repair next year, a torch-down section the year after — once those total exceed 25% within a 12-month window, code requires a full re-roof to current standards (ice-and-water shield, drip edge, full underlayment).

We assess every flat roof up-front and tell you exactly where you stand: small repair, silicone restoration, or full torch-down replacement. Read more on the 25% rule →

How It Works

Our Flat Roofing Process

Five steps from first call to final inspection. We diagnose every flat roof on-site before quoting — no over-the-phone estimates.

Site Assessment

On-site inspection within 48 hours. We core-sample, photograph, check parapets and drains, and document the existing system.

System Recommendation

Based on roof condition we recommend repair, silicone restoration, or full torch-down — and explain the cost-life tradeoffs.

Permits & Quote

Line-item written estimate, permit filing with the local building department, dumpster scheduling, and a weather-friendly install date.

Installation

Manufacturer-trained crew, daily site cleanup, weather contingencies. We pull off when conditions can’t support a clean install.

Frequently Asked

Flat Roofing FAQ

Torch-down roofing is a full replacement system used when the existing flat roof is failing, saturated, or no longer a good candidate for restoration. Silicone coating is a restoration system designed to waterproof and extend the life of an existing roof that is still structurally sound. In simple terms, torch-down is usually the right choice when the roof needs to be replaced, while silicone can be a strong alternative when the current roof has good structure, proper adhesion, and manageable drainage conditions.
Flat roof pricing in Hudson County depends on roof size, access, existing layers, decking condition, drainage needs, insulation requirements, and whether the best system is full torch-down replacement or silicone restoration. Dense towns like Union City, Hoboken, West New York, and Jersey City often add staging and access considerations that affect the final scope. Gaby Roofing provides an on-site inspection and written line-item estimate so the property owner understands the recommended system and why it is being proposed.
Most professionally installed modified bitumen flat roofs in Hudson County last around 15-25 years depending on drainage, ponding water, weather exposure, roof maintenance, and installation quality. Gaby Roofing backs full roof replacement systems with a 10-year workmanship warranty. A silicone restoration system may extend the useful life of a roof when applied before the existing membrane reaches the end of its service life.
