On a building with shared party walls, water travels before it shows. We trace from the roof down to the true entry point — drains, flashing, coping, seams, penetrations — before anything gets patched.
Patching directly above a stain is the single most common reason a “fixed” leak comes back.
Reliable information, even before an inspection.
The assumptions that lead to a repair that fails again.
Rarely the open field of the membrane — almost always one of these.
The wall around the roof edge and its cap metal. Displaced or cracked coping is the single most common leak source on a Hoboken flat roof.
Where the membrane turns up a shared wall. This detail moves with the building over time and is a frequent failure point on row houses.
A clogged or settled drain holds standing water that finds its way in at the drain bowl itself, not the membrane around it.
Skylights, old chimney stubs, vents and mechanical curbs — anywhere the membrane was cut and detailed around an object.
Where two sheets of membrane join. Age and thermal movement can open a seam years after installation, in the open field of the roof.
On a shared party wall, water entering next door can travel and surface on your side — ruled in or out before anything is repaired.
Tracing a leak properly is most of the job. Once the true entry point is confirmed, the repair itself is usually straightforward.
One square mile. Wherever your building sits, it is the same crew and the same tracing process.
We will trace it to the true source, then send a written estimate. No obligation — and no price quoted over the phone before anyone has seen the roof.

Not necessarily. Water follows the path of least resistance once it’s inside the roof assembly or a party wall, so it can travel several feet before it shows up as a stain. We trace from the roof down to confirm the true entry point rather than patching wherever the ceiling is wet.
Yes, on a shared party wall this happens regularly in Hoboken. Water entering the roof next door can travel along the shared structure and show up on your side. Confirming this before repairing anything saves you from fixing a leak that was never on your roof to begin with.
Most leaks are traced in a single on-site visit — checking drains, flashing, coping, seams and penetrations systematically rather than guessing. Complex or intermittent leaks occasionally need a second look during or right after rain.
A repair done at the true entry point, to the right detail, should hold. Leaks that “come back” are almost always ones that were patched at the visible symptom instead of the actual source — which is the entire reason we trace first.
An inspection, photographs and a confirmed entry point — at no cost and with no obligation.
