Gaby Roofing is a licensed flat roof contractor NJ homeowners and businesses trust for durable, leak-free roofing across North Jersey. We specialize in flat roof installation and repair, full shingle roof replacements, and commercial roofing projects throughout Hudson County. Whether you need a new torch down roof on a brownstone in Jersey City or a full architectural shingle replacement in North Bergen, our team delivers tight workmanship, clean job sites, and warranties that actually hold up.
Family-owned and fully insured under NJ Home Improvement Contractor license #13VH11705800, we have spent years building a reputation for honest quotes and long-lasting roofs. Every project — from a small flat roof patch to a full tear-off — gets the same attention to detail, the same quality materials, and the same direct communication from start to finish.
Flat Roofing Specialists — Torch Down and Silicone Systems
Flat roofing is where we built our name. For North Jersey’s row houses, multi-family buildings, and low-slope commercial roofs, we install two proven systems: torch down modified bitumen and silicone roof coatings. Both are engineered for the freeze-thaw cycles, heavy summer rain, and ponding water that North Jersey roofs face every year.
Torch down roofing is a multi-ply SBS modified bitumen system heat-welded directly to the substrate. It creates a fully bonded, monolithic membrane that resists tearing, punctures, and foot traffic — ideal for urban roofs that double as access surfaces. Torch down roofs routinely last 20+ years when properly installed with the right base sheet and flashing detail.
Silicone roof coatings are the smart choice for restoring aging flat roofs without a full tear-off. A high-solids silicone system seals leaks, reflects heat, and adds a decade or more of waterproof service life at a fraction of replacement cost. Silicone holds up where acrylics fail — it does not wash off in standing water and does not chalk out in UV. For owners trying to extend roof life and cut cooling bills, this is the system we recommend.
Shingle Roofing & Full Roof Replacement
On pitched roofs, we install premium architectural shingles from the manufacturers homeowners know: GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark. Every shingle roof replacement includes full tear-off to the decking, inspection and replacement of any rotted sheathing, ice and water shield at eaves and valleys, synthetic underlayment, new drip edge, proper ridge ventilation, and matching ridge cap shingles.
We do not cut corners with overlays, re-used flashings, or nail-gun shortcuts. A shingle roof installed properly should last 25–30 years — and ours do. Ask about manufacturer system warranties when you book your free evaluation.

Gaby Roofing serves homeowners, landlords, and business owners across Hudson County and the surrounding North Jersey area. Our core service areas include Jersey City, Hoboken, Union City, North Bergen, and West New York, and Bayonne.

Free Roof Evaluation — Call 201-638-8556
Every roofing project starts with a free, no-pressure evaluation. We climb the roof, photograph what we see, and walk you through options in plain English — torch down vs. silicone recoat, full shingle replacement vs. targeted repair, what your insurance should or should not cover. You get a written estimate with scope, materials, and warranty spelled out. No hidden add-ons. Call 201-638-8556 or request your evaluation online to get on the schedule.
