From the loft
Where there is access, the sheathing is read from below. Old staining is grey and dry at the edges; active staining is dark and damp, and the difference tells you whether you are chasing something live.
Roof Leak Repair in Gibbsboro, NJ
A stain on a ceiling is where water stopped, not where it started. The job is working back up the path before anybody opens a tube of sealant.
In short
Water travels before it drips
It runs down a rafter, along a wire, across the top of a ceiling joist, and comes through wherever the plaster gives up first. A metre of horizontal travel is ordinary. Sealing the slope directly above a stain is how a leak gets fixed three times and keeps coming back.
How it is traced
Inside first, then out
From the slope
The suspected area is examined for the usual culprits: a lifted nail, a split boot around a pipe, a flashing that has pulled away from a sidewall.
With water, where it is needed
A hose run on one section at a time, with somebody inside, when the path is genuinely unclear. It is slow and it is the only method that proves anything.
Fixed and written up
The repair, plus a note on anything nearby heading the same way, so the next one is not a surprise.
Worth knowing
Not every ceiling stain is the roof
Condensation in a poorly ventilated loft, a bathroom fan venting into the attic instead of out of it, and a leaking pipe in a ceiling void all produce a mark that looks exactly like a roof leak. All three are worth ruling out before anybody climbs a ladder, which is why the first part of the visit happens indoors.

A full tear-off planned around the frontage first, so four tons of old covering leaves the street without closing it.
