As a Frankfort commercial roof leak repair contractor, we trace water from the stain inside back to the failed detail on the roof and rebuild it.
Frankfort commercial roof leak repair starts with the roof type, because each system has its own weak points and that narrows the search before anyone cuts.
| Roof Type | Usual Leak Sources | First Detail Checked |
|---|---|---|
| TPO and PVC | Seam edges, curb corners, pipe boots | Welded laps near the stain |
| EPDM | Seam tape edges, shrinkage at walls, flashing corners | Tape edges and wall terminations |
| Modified bitumen | Lap edges, blisters, torch-applied wall flashing | Wall base and lap lines |
| Built-up | Cracked flashing, blisters, pitch pans | Pitch pan filler and wall flashing |
| Metal panel | Fastener washers, end laps, ridge caps, wall trim | Screw lines upslope of the drip |
Most leaks come from a short list of details where the roof meets something that moves, vibrates, or ages at a different rate than the membrane.
Steel deck flutes carry water downslope toward walls, purlins move it sideways to a low point, and insulation joints spread it under the membrane. Pipes and conduit then drop it at hangers, so the drip can sit many feet from the hole.
Usually Means: the search starts above the stain and works upslope, one seam, curb, and penetration at a time.
Sealant fails at curb corners and under the unit flange as equipment vibrates.
Filler pulls away from the pipe and leaves a gap that lets water in with every rain.
Leaves in the strainer push water over the flashing and into the wall.
Leaks that show only in wind-driven rain often trace to coping or wall flashing above.
Once the source is found, the fix matches the detail that failed. These four repairs close most commercial roof leaks.
Rooftop unit curbs get new membrane flashing up the curb face, with counterflashing reset where the old fasteners rusted out.
Pitch pans are swapped for prefabricated pipe boots, or refilled sealant pockets where a boot cannot fit the roof penetration.
Membrane is reset into the drain bowl with new clamping ring bolts, and rusted scupper sleeves are replaced with new flanges.
Open seams found during tracing get patched with membrane matched to the roof, extended past the opening on every side.
Fixing the detail that let water in, rather than the spot where it dripped, is what keeps the same leak from coming back.
Tracing upslope finds the opening on the first visit, so the ceiling stain stops growing and nobody patches dry membrane by mistake.
New flashing at unit curbs holds up to the vibration that cracked the old sealant at the corners.
A reset drain bowl and a clean strainer keep water from climbing the flashing during heavy storms.
Moisture readings during tracing show wet board before it spreads, so the repair stays small.
Leaks that appear only with wind-driven rain often start at coping or wall flashing. Note the wind direction next time and call us to trace it.
Call UsLeak tracing moves from inside to the roof, then tests one detail at a time so the source is clear.
Stains, drips, and wet ceiling tiles are mapped inside first, then the roof above gets walked at every flashing, lap, curb, and drain upslope of them.
Meters and probes read the membrane, and an infrared scan at dusk can show where wet insulation holds the day's heat.
Controlled water testing starts low and moves up, so each curb, boot, or lap gets tested alone and the leak shows itself.
The failed detail is rebuilt with matching membrane or flashing, then checked again during the next heavy rain.
Tracing often points to a larger repair on one part of the roof. These services pick up from there.
Seams opening along whole runs or ponding near the leak lead to flat roof repair across that section.

Drips tracing back to a purlin line or end lap lead to fastener and lap work on the metal panels.

Plant roofs with exhaust fans and long drain lines need repairs scheduled around production.
Industrial roof repairBy matching interior stains to roof features above them and checking every seam, curb, and penetration upslope. Moisture meters, probes, and dusk infrared scans narrow it down, and controlled water testing confirms the source one detail at a time. Leaks that appear only in wind-driven rain often trace to wall flashing or coping.
TPO and PVC leak at seam edges, curb corners, and pipe boots. EPDM fails at tape edges and walls where it shrinks, modified bitumen at laps and torch-applied wall flashing, built-up roofs at cracked flashing and pitch pans, and metal roofs at fastener washers and end laps. Clogged drains cause leaks on every low-slope type.
They join the roof to things that move, vibrate, or age at a different rate than the membrane. Curb corners lose sealant, pitch pan filler shrinks away from the pipe, boots split at the upper band, and counterflashing pulls off walls when its fasteners rust. Each one gets reflashed, refilled, or replaced.
The membrane is reset into the drain bowl or scupper sleeve and cracked or rusted parts are replaced. That means new clamping ring bolts, a drain insert where the bowl is cracked, new metal flanges for rusted scupper sleeves, stripped-in flashing, and strainers that keep leaves out. Fall cleanouts prevent much of the trouble.
Only temporarily. Wet-surface sealants, rated tapes, and weighted plastic sheeting can slow the water, and clearing a backed-up drain helps right away. The permanent repair waits for a dry roof, because primers, tapes, and welds bond only to clean, dry surfaces. Lightning and high wind keep everyone off the roof.
Mark where the water shows up inside, note the weather when it happened, and call us. We will trace it from there.
