Flat Roof & Shingle
Roofing Contractor in NJ
Gaby Roofing is a licensed roofing 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 Firestone 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. We're a family operation through and through — Damian's on every roof we build, start to finish, making sure it's done right.
Torch-Down & Silicone Systems for North Jersey Flat Roofs
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 engineered for our freeze-thaw cycles, summer rain, and ponding water.
Firestone · Modified Bitumen
Torch-Down Roofing
A multi-ply SBS modified bitumen system heat-welded directly to the substrate. Creates a fully bonded, monolithic membrane that resists tearing, punctures, and foot traffic — ideal for urban roofs that double as access surfaces.
- 20+ year service life
- Multi-ply puncture resistance
- Walkable surface
- Heat-welded watertight seams
Tri-Built 985 · Silicone Coating
Silicone Roof Coating
High-solids silicone seals leaks, reflects heat, and adds a decade of waterproof service life — with renewable surface technology. Holds up where acrylics fail: doesn't wash off in standing water, doesn't chalk in UV.
- Renewable surface system
- Reflective Energy Star finish
- Ponding-water resistant
- Restores roofs without tear-off
Architectural Shingle Replacement Done Right
On pitched roofs, we install premium architectural shingles from the manufacturers homeowners know. Every shingle replacement is full tear-off — no overlays, no shortcuts, no nail-gun cheats.
Every replacement includes the full system — not just the visible shingles:
- Full tear-off to decking
- Rotted sheathing replacement
- Ice and water shield (eaves & valleys)
- Synthetic underlayment
- New drip edge & ridge ventilation
- Matching ridge cap shingles
A shingle roof installed properly should last 25–30 years — and ours do. Every install includes a written workmanship warranty on top of the manufacturer’s coverage, plus a final inspection Damian walks personally.
Serving Hudson County, NJ
We serve homeowners, landlords, and business owners across Hudson County and the surrounding North Jersey area. We know these neighborhoods — the row-house flat roofs, the older shingled two-families, the mixed-use commercial buildings — and we price every project honestly based on what the roof actually needs.
Free Roof Evaluation · No Pressure, No Obligation
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 — which makes sense for your roof
- Full shingle replacement vs. targeted repair
- What your insurance should or should not cover
- Written estimate with scope, materials, and warranty spelled out
