Flat Roof Specialist in Bayonne, NJ

Gaby Roofing is the flat roof specialist trusted across Bayonne. From the row homes and brownstones along Broadway, Avenue C, and 22nd Street to the mid-rise walk-ups, two- and three-family properties, and small commercial buildings that fill the neighborhood, our crews have installed, repaired, and recoated flat roofs on nearly every block. We know how Bayonne’s wind-driven rain off the Hudson, brutal summer heat on dark membranes, and freeze-thaw cycles attack a flat roof. We do one thing: flat roofs. That focus is why Bayonne property owners call us when a leak, a full replacement, or a 25-year torch down install is on the line.

Why Flat Roofs Dominate Bayonne

Bayonne sits in the most densely built stretch of Hudson County. The row homes, three-family walk-ups, Victorian-era brownstones, and mid-rise apartment buildings that define the skyline almost all carry flat or low-slope roofs. Zero-lot-line construction, shared parapet walls, and the need to maximize interior height made flat roofing the standard long before modern codes. That density is why modified bitumen torch down, silicone coatings, EPDM, and TPO are the systems that actually perform here — pitched shingles are not an option on most Bayonne buildings.

Bayonne Flat Roof Permits, Inspections & the Building Department

Bayonne requires permits for flat roof replacement and for repairs affecting more than 25% of the roof area per the New Jersey Uniform Construction Code and IBC §1511. Permits are issued through the Bayonne Division of Construction, located at 630 Avenue C, Bayonne, NJ. Reach the office at 201-858-6076 to confirm submission requirements or schedule an inspection.

We pull every permit ourselves. Because we have worked with Bayonne inspectors on dozens of flat roof projects, we know exactly what they check at inspection — drainage slope to scuppers and internal drains, parapet wall flashing and counter-flashing details, torch down seam overlap of at least 3 inches, and proper termination around HVAC curbs and skylights. That familiarity expedites approval and prevents costly re-inspection fees.

Homeowners who hire unlicensed roofers in Bayonne regularly get red-tagged, which means a forced tear-off and restart at the owner’s expense. Our permit track record means your flat roof job passes inspection the first time.

The 25% Rule in Bayonne

New Jersey code applies the 25% rule to every flat roof in Bayonne. If more than 25% of the roof area is damaged or being replaced, the code requires full replacement rather than a patch. We give you a straight answer on which side of that line your roof falls. Read the full breakdown on our 25% Rule: Repair or Replace guide.
