Leak Sources on Jeffersontown Commercial Roofs
Each roof type has its own short list of places where leaks begin.
TPO and PVC
Unwelded Seam Edges
Seam edges that never fully welded, curb corners, and pipe boots are where single-ply roofs start leaking. Water follows the lap until it finds the gap.
EPDM
Failing Seam Tape
Rubber roofs leak where seam tape lets go, where the sheet shrinks away from the walls, and where flashing cracks at penetrations.
Metal Panel
Laps and Fasteners
Panel roofs leak at screw washers, end laps, ridge caps, and skylight panels. A straight line of drips usually follows one fastener row.
Every Roof
Curbs, Drains, and Edges
Rooftop unit curbs, roof drains, and parapet edges rank among the most frequent sources on every roof type around Jeffersontown.
How Commercial Roof Leak Repair Works in Jeffersontown
Tracing comes before patching, because the stain inside rarely sits directly under the opening.
Mark the Drip
Drip spots inside are marked and measured from the walls, then matched to the roof area above and upslope from them.
Check the Usual Suspects
Curbs, pipe flashings, seams, and drains near that area get checked first, since most leaks start at one of them.
Read the Moisture
A moisture meter or infrared scan shows where insulation is wet, which outlines how far water has traveled under the membrane.
Test With Water
When the source stays hidden, a controlled water test on one suspect area at a time confirms it before any repair.
What Fixing the Real Source Changes in a Jeffersontown Building
A repair at the true opening ends the cycle of patches that miss and stains that come back.
One Repair Instead of Three
Finding the opening first puts the patch where water enters, rather than over the spot that looked guilty from below.
Wet Insulation Mapped
Moisture readings show which boards are wet, so they get replaced instead of sealed in under a new patch.
Stock and Equipment Protected
Inventory, records, and electrical gear under the drip stay dry once the curb or seam above them is sealed.
Storm Patterns Explained
Tying each leak to rain, wind, or snowmelt shows whether the next fix belongs at a drain, a wall, or a gutter.
Condensation Ruled Out
Separating condensation from a true leak keeps money off the roof when the fix belongs in ventilation or insulation.

Our Leak Tracing and Repair Sequence
Leak work moves back and forth between the roof and the rooms under it until the source is confirmed.
- On The Roof
Inspect Your Roof
The crew walks the roof above and upslope of the reported drip, checking curbs, pipe flashings, seams, and drains, and photographs what it finds.
- Around The Building
Trace Water Marks Inside
Water marks on the deck, purlins, and ceiling are followed back toward the high side, since water often runs several feet before it falls.
- On The Roof
Confirm With Readings or a Water Test
Moisture readings outline the wet area. If the source stays hidden, a controlled water test on one suspect area confirms it.
- On The Roof
Seal the True Opening
A temporary seal goes on first if rain is coming. The permanent repair uses matching materials on a clean, dry surface.
- Around The Building
Watch the Next Rain
Photos and roof-plan notes go to the facility manager, who reports whether the spot stays dry through the next storm.

Questions facility managers ask while they wait for the roofer.
How do crews find the source of a commercial roof leak?
Crews start inside under the stain, trace water marks back along the deck or purlins, then search the roof above for a matching opening. Curbs, pipe flashings, seams, and drains come first, with a moisture meter, an infrared scan, or a controlled water test when the source stays hidden. Water often runs several feet before it falls.
Where do leaks usually start on each type of commercial roof?
TPO and PVC leak at unwelded seam edges, curb corners, and pipe boots. EPDM leaks at seam tape, walls where the sheet shrinks, and cracked flashing. Modified bitumen fails at laps, blisters, and base flashing; built-up roofs at ply splits, pitch pans, and drain flashing; metal at fasteners, end laps, ridge caps, and skylights.
Why does my roof leak in some storms but stay dry in others?
The opening is one that water reaches only under certain wind directions or rain depths. Wind-driven rain pushes water sideways into wall flashing, counterflashing joints, and parapet caps. Heavy-rain-only leaks suggest a drain that backs up, and drips after snowmelt suggest ice at gutters or blocked drains. Logging date, wind, and rain for each leak narrows the search.
Is the water inside a roof leak or condensation?
Timing and pattern tell them apart. A leak follows rain or snowmelt and drips from one spot or a short line under a curb, seam, or lap. Condensation shows up on cool, dry mornings, spread across a large area as beads under bare metal or cold spots, and calls for ventilation or insulation work rather than a roof repair.
What can a facility manager do while a leak waits for repair?
Protect what sits under the drip and keep people safe. Move stock and records, set buckets or tarps, mark the floor for slip hazards, and shut off power to nearby fixtures if needed. Photograph the stain and note the time, weather, and wind direction when it started. Leave roof access to the roofing crew, especially during storms.
Why does the stain sit away from the actual leak?
Water that gets through the membrane runs along the top of the insulation, the deck flutes, or a purlin until it finds a seam or low spot to drip through. On a large roof that path can be several feet long, so the opening often sits upslope of the stain.
