The Flat Roof Repairs We Handle Most
Hudson County’s housing stock is overwhelmingly flat-roofed — row homes, brownstones, multifamilies, and mixed-use buildings, most with modified bitumen (torch-down) membranes. After 23+ years on these exact roofs, the failure points are predictable, and so are the correct fixes.
Active Leaks & Water Stains
A ceiling stain rarely sits directly below the entry point — water travels along the deck before it drips. We trace the leak on the roof, not by guessing from the ceiling, and repair the actual entry point with a torch-down patch heat-welded into the existing membrane — not a smear of roof cement that fails next season.
Parapet Walls & Flashing
The most common leak source on Hudson County row homes isn’t the field of the roof — it’s the parapet walls and the flashing where the membrane turns up against them. We re-flash parapets with modified bitumen turned up and terminated correctly, and re-seal or replace coping where it’s the real culprit.
Ponding Water
Water still standing 48 hours after rain shortens any membrane’s life. Depending on severity we correct ponding with drainage improvements, tapered patching, or a silicone restoration system rated for ponding water.
Silicone coating →Seams, Blisters & Splits
Torch-down seams open with age and thermal movement; trapped moisture forms blisters that eventually crack. We cut out and re-weld failed sections with matching Firestone SBS-modified bitumen so the repair moves with the roof instead of against it.
Drains, Scuppers & Gutters
Clogged or rusted-out drains and scuppers back water up under the membrane. We clear, re-flash, or replace roof drains and through-wall scuppers — a small repair that prevents a full-roof failure.
Skylights, Pipes & HVAC Curbs
Every penetration is a potential leak. Pipe boots, skylight curbs, HVAC stands, and roof-deck posts all need flashing that’s tied into the membrane, not caulked over. We re-flash penetrations with the same heat-welded modified bitumen as the field of the roof.
Torch-Down, Silicone, EPDM — We Repair Them All
Torch-down (modified bitumen) is our specialty — heat-welded patches and re-flashing with Firestone SBS-modified bitumen. We also repair silicone-coated roofs (spot repair, seam reinforcement, and re-coating with Tri-Built 985), EPDM rubber membranes, built-up tar-and-gravel roofs, and commercial flat roofs on warehouses, mixed-use, and multifamily buildings — and we tell you honestly when a roof is past the point of repair.

Flat Roof Repair & Torch-Down Replacement
We’ll Tell You Straight
Not every leak needs a new roof — and not every roof should keep absorbing repairs. NJ’s reroofing code has a threshold (the 25% rule) where accumulated repair work triggers a full-replacement obligation. We inspect on-site, photograph what we find, and tell you exactly where your roof stands: a targeted repair, a silicone restoration at roughly half the cost of replacement, or a full torch-down replacement.
