Flat Roofingin Hudson County, NJ
Family-owned flat roofing contractor for 20+ years. Firestone modified bitumen torch-down replacements, Tri-Built 985 silicone restorations, and emergency leak repair for residential and commercial buildings across Hudson County.
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.
Torch-Down Replacement
Firestone SBS-modified bitumen torch-down systems. The many years flat roof solution for full replacements and end-of-life tear-offs.
Torch-down details →Silicone Restoration
Tri-Built 985 high-solids silicone coating that restores aging flat roofs without a tear-off — as a complete restoration system of full replacement.
Silicone details →Leak Repair & Diagnostics
Same-day or next-day emergency tarping and leak diagnosis. Parapet flashings, scuppers, drain replacements, and small-area patches.

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
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 →
