The scope documents leak sources, repair boundaries, photos, and priorities so Evansville owners can separate immediate stabilization from longer-term capital work. A ceiling stain almost never sits right under the leak that caused it. Water travels along deck flutes, insulation joints, and structural members before it finds a spot to drip through, sometimes twenty or thirty feet from where the roof membrane actually failed. Chasing the wrong spot wastes a maintenance crew's time and leaves the real breach open to get worse.
On a metal deck building, water that gets under the membrane runs along the flute pattern until it hits a low point, a seam in the deck, or a penetration where it can drop straight down. That's why we start every leak call by getting up on the roof and working outward from the interior stain location, rather than assuming the leak is directly above it. Flashing details, curb seams, and old pitch pockets near the general area are checked first, since those account for a large share of the leak calls we run.
Humidity works against us on this kind of diagnosis. In the Ohio Valley, a roof deck can stay damp for days after a rain event, which sometimes masks exactly where the active moisture is entering versus where it's just lingering from the last storm. We use moisture meters and, when needed, infrared scanning to separate old damp insulation from a live entry point before cutting anything open.
Rooftop unit curbs are one of the most common failure points we find, especially on buildings where HVAC equipment has been serviced or replaced without the flashing being properly re-terminated afterward. Pipe boots crack and split from UV exposure over a hot Indiana summer. Parapet wall coping that's come loose lets wind-driven rain behind the wall system during the spring storm line that regularly moves through the Tri-State. Seam failures on older single-ply membranes show up most often on the south and west exposures, where sun load is heaviest through the day.
On buildings near the river with heavier equipment traffic on the roof, distribution centers, manufacturing plants with rooftop-mounted process equipment, punctures from dropped tools or dragged equipment account for a real share of leaks too. Those are usually the fastest repairs once located, but finding the actual puncture among a field of foot traffic marks takes a careful walk.
That sequence keeps us from cutting into a roof based on a guess. A test cut in the wrong spot adds a repair point that didn't need to exist, which is the opposite of what a leak call should accomplish.
Once the source is confirmed, the repair method depends on the membrane type and how much of the surrounding area is affected. A single failed seam on TPO gets heat-welded and tested. A cracked pipe boot gets replaced outright rather than caulked over, since caulk on a boot is a temporary fix at best in this climate. If moisture has spread into the insulation beyond a small area, we'll cut back further than the visible damage to make sure we're not sealing wet board under a new patch, which would just cause the same leak to reappear months later.
We photograph the repair area before and after, so the facility manager has a record of what was found and what was done, instead of an invoice line that reads “leak repaired.”
A building that calls for the same general leak twice usually has a root cause that wasn't fully addressed the first time, or a second failure point nearby that got missed. We flag any additional wear we see near the repair area during a leak call, a flashing edge starting to lift, a drain strainer that's partially clogged, even if it's not what triggered the current leak, because catching it now is cheaper than a second emergency call after the next storm.
Water usually runs along the deck or insulation before it drops through the ceiling, so the actual breach in the membrane can be well away from where the stain shows up inside the building.
Active leaks get prioritized, especially during spring and summer storm season when a compromised roof can take on significant water in a single event.
Yes. A roof deck that stays damp after rain can mask exactly where new water is entering, which is why we use moisture meters and infrared scanning rather than relying on a visual check alone.
It depends on the manufacturer and who performs the work. We document every repair with photos and materials used so it stays consistent with warranty requirements where applicable.
Rooftop unit curbs and pipe boots account for a large share of the calls we run, particularly on roofs where equipment has been serviced without the flashing being properly restored afterward.
