TPO Repairs
Weathered sheet is cleaned with a membrane cleaner, then a heat-welded TPO patch goes on, reaching past the damage on every side. Old TPO that refuses a weld gets a cover strip.

Is This Flat Roof Ready for Repair?
An Owensboro flat roof repair contractor starts by sorting what a patch can fix from what needs a bigger plan. This table shows where that line falls.
| Condition | Repair Fits | Plan For More |
|---|---|---|
| Seams | A few open laps or T-joints | Seams failing across the whole field |
| Insulation | Dry, or a small wet area cut out | Wet readings across several bays |
| Ponding | A clogged drain or one low spot | Deck sag across a wide area |
| Blisters and splits | Isolated, with bonded membrane around them | Clusters across the field or repeat splits on deck joints |
| Old TPO | Takes a weld after cleaning | Resists welding and needs cover strips or a larger section |
Flat Roof Repair Problems Owensboro Owners See
Flat roofs give warning signs in three places before a small leak turns into wet insulation.
From The Parking Lot
Overflowing Scuppers
Sheeting water over a scupper box means the drain line behind it is blocked or too small.
Loose Edge Strips
Edge metal lifted by wind leaves the membrane edge open along the parapet.
Inside The Building
Stains Away From Drains
Water travels under single-ply sheets and along deck flutes, so drips land well away from the opening.
Cold Ceiling Spots
An area that stays colder than the rest in winter can sit under soaked insulation.
On The Roof
Lifted Seam Edges
A probe slides under laps that have lost their bond, most often at T-joints.
Rings After Rain
Dirt rings mark water that sat for days, which speeds seam wear and adds weight.
Blisters And Splits
Raised bubbles show trapped air or moisture, while straight splits tend to follow deck joints.
Commercial Roof Repair Options for Owensboro
Each membrane takes its own repair method. Mixing materials is what makes patches fail, so the membrane type is confirmed with a small cut first.
EPDM Repairs
Rubber is scrubbed and primed before seam tape or an EPDM patch is rolled in. Shrinkage pulling the sheet away from walls is fixed with new base flashing.
Modified Bitumen Repairs
Loose granules are removed, then a torch-down or cold-applied patch is set over the lap or blister so it sheds water downslope.
Built-Up Roof Repairs
Gravel is pushed back, blisters are cut and dried, and felt layers with asphalt or cold-process material rebuild the spot before the gravel returns.
Benefits of Repairing Your Roof
Fixing a flat roof at the seam keeps the rest of the system working for everyone who uses the building.
Owner
- Dry insulation around a repaired lap keeps restoration on the table later.
- Crickets and cleared drains cut the ponding that wears seams early.
- Each patch is logged, so repeat problems at one curb show up in the record.
Facility Manager
- Walkway pads to each rooftop unit stop service traffic from crushing insulation.
- Marked roof plans show which ponds come back after rain.
- Temporary patches are flagged and replaced once the membrane is dry.
Tenants And Staff
- Drips over desks and shelving stop once the entry seam is closed.
- Musty air above offices clears once wet boards under the membrane come out.
- Patch work near air intakes uses low-odor products where available.
Water Standing on Your Flat Roof?
Call with the spots where water sits after rain and where it shows up inside. Clearing a drain is often the first fix.
Flat Roof Repair Steps for Owensboro Buildings
Five steps, from the first probe of a seam to a dry, sealed patch at the end.
Inspect Your Roof
We check seams, laps, and flashing edges upslope of the stain, then take moisture readings across the suspect area to see how far water has spread.
Confirm The Membrane
A small cut tells the crew whether the roof is TPO, EPDM, modified bitumen, or built-up, so the right patch material is ordered.
Cut Out Wet Material
Damaged membrane is cut back and soaked insulation comes out. New boards and cover board go in at the same height as the old.
Patch And Seal
Heat welds, primed tape, or torch-down cap sheet close the opening, with the patch running past the damage on all sides.
Check For Ponding
Drains are cleared and low spots marked. If water returns to the same place after rain, crickets or a lowered drain ring come next.

Answers on finding, patching, and drying out flat commercial roofs.
Finding Leaks
How do you find a leak on a flat commercial roof?
Work starts at the interior stain and moves up to the roof, checking every seam, flashing, and penetration upslope of that spot. Probing laps, moisture meter readings, and water tests on one detail at a time narrow it down, since water travels under membranes and along deck flutes.
What causes ponding on a flat roof and can it be repaired?
Sagging deck, clogged drains, crushed insulation, or drains set higher than the roof around them. Clearing strainers, lowering drain rings with a new sump, adding tapered crickets, replacing crushed boards under walkways, or adding a drain at a chronic low point all reduce it. Deck sag over a wide area is structural work.
Membranes
How are TPO, EPDM and modified bitumen roofs repaired differently?
TPO takes a heat-welded patch after cleaning, EPDM takes primer with seam tape or an EPDM patch, and modified bitumen takes a torch-down or cold-applied patch once loose granules are gone. Built-up roofs get felt and asphalt or cold-process layers. Mixing materials is what makes patches fail.
Can blisters and splits in a flat roof be repaired?
Yes, when the membrane around them is still bonded and the insulation below is dry. A blister is cut open in an X, dried, checked underneath, then re-adhered or trimmed and covered with matching material. Splits get cleaned and sealed with a reinforced strip. Repeat splits along deck joints show movement that needs its own fix.
Insulation
How is wet insulation under a flat roof handled during repair?
It comes out. Soaked boards hold water against the deck and stop insulating, so the crew marks the wet area with readings, cuts the membrane, removes the boards, checks the steel deck for rust, installs new insulation and cover board, and seals the opening. Large wet areas raise the replacement question.
Does a flat roof repair need dry weather?
The permanent patch does. Welds, primers, and adhesives need a clean, dry surface to bond. During rain the crew can set a temporary patch to stop water, then marks it and removes it once the roof dries, so mastic never sits under the finished weld.
