Repair the Section or Replace the Roof?
An Owensboro commercial roof repair contractor sorts each leak into one of these two answers, based on how much of the roof is still dry.
Roof Replacement
- Fits When
- Wet boards and splits across the field
- Core Cuts
- Wet in many areas
- Materials
- New assembly from deck to edge
- On Site
- Crane, chutes, daily tie-ins
- Next Step
- Permit check with the local office
When the answer is replacement, the system choice moves to TPO, EPDM, or metal panels.
Commercial Roof Repair Calls We Get in Owensboro
These five leaks make up most repair calls, and each one has a usual source on the roof.
Drip under a roof drain
Likely CauseLoose clamping rings or a cracked drain bowl let water slip under the membrane right at the outlet.
What We DoWe reset or replace the clamping ring and strainer, then weld or tape a target patch around the drain.
Wet ceiling tile beside a rooftop unit
Likely CauseCurb flashing splits at the corners, and old pitch pans dry out and pull away from pipes.
What We DoCorners get reflashed with the membrane maker’s parts, and pitch pans are swapped for boots that fit the pipe.
Bubbles rising in the membrane
Likely CauseMoisture or air trapped between layers expands in summer heat and lifts the sheet into blisters.
What We DoBlisters are cut, dried, and patched, and a core cut nearby shows whether the boards underneath are wet.
Water running down a parapet wall
Likely CauseCoping joints open up and counterflashing works loose, so rain gets behind the wall flashing.
What We DoCounterflashing is refastened, coping joints resealed, and the wall flashing terminated under the cap again.
Leaks only during wind-driven rain
Likely CausePerimeter edge metal and open laps near corners catch rain that blows sideways under them.
What We DoEdge metal is refastened at a tighter spacing and the laps along the perimeter are cleaned and resealed.
Commercial Roof Repair Options for Owensboro Buildings
Repairs are matched to the roof that is already there, so the patch and the old sheet bond or weld as one.
Membrane Seam Repair
Open TPO and PVC seams are cleaned and rewelded with hot air; EPDM laps get primer, new seam tape, and lap sealant at the cut edges.
Flashing And Penetration Repair
Curbs, pipe boots, skylight frames, and wall flashing are reflashed with matching material so the repair turns up and seals at full height.
Drain And Scupper Repair
Clamping rings, strainers, and scupper linings are reset or replaced, and clogged outlets are cleared before any patch goes down.
Metal Fastener And Lap Repair
Backed-out screws give way to larger ones with new washers, and open side or end laps get butyl tape and stitch screws.
Benefits of Repairing Your Roof Early
A small leak left alone spreads through the assembly. Fixing it early keeps the damage to one spot.
Water spreading through insulation
Each rain pushes water farther along the deck and soaks more boards around the original leak.
What The Repair DoesSealing the entry point keeps the wet area small enough to cut out and replace during the repair.
Rust starting on the steel deck
Wet boards hold water against the deck flutes until the steel softens and needs replacing.
What The Repair DoesDry boards and a sealed membrane stop the rust before deck sections have to be cut out.
Damage to stock and ceilings below
Drips land on racking, equipment, and ceiling tile long before the roof itself looks bad.
What The Repair DoesStopping the drip protects what sits under the roof while a longer plan is worked out.
Seams opening wider each winter
Water in a small gap freezes on cold nights, expands, and pries the lap open a little more.
What The Repair DoesA welded or taped repair closes the gap before freeze-thaw cycles can widen it.
Water Dripping Near a Roof Drain?
Call and tell us which drain or which bay. Drain leaks often trace to a loose clamping ring that is quick to find on the first visit.
How an Owensboro Commercial Roof Repair Contractor Works a Leak
Five steps, in order, from the stain inside to the dry roof above it.
Inspect Your Roof
The whole roof gets walked, not only the leak area, because a second weak seam or a clogged drain nearby will cause the next call.
Trace It To The Source
Interior stains are matched to roof locations, then seams are probed and flashings checked uphill of the stain, since water travels along the deck.
Repair Or Replace The Section?
Core cuts show whether the insulation around the leak is dry. Wet boards are cut out and replaced before the membrane is closed.
Match The Material
TPO is welded to TPO, EPDM is taped to EPDM, and metal panels are swapped for the same profile and gauge.
Test And Record
Welded seams are probed, drains are run with water where safe, and dated photos of each repair go into your roof file.
When a Repair Turns Into a New Roof
If the roof walk finds more wet area than dry, these are the next pages to read.
Flat Roofing
Ponding behind units and around drains usually needs tapered insulation or new outlets, which a patch cannot add.
TPO Roofing
Large low-slope roofs with failing seams across the field often move to a new welded white membrane.
Metal Roofing
Rust holes across many panels or sagging purlins call for framing repair and new panels on the whole slope.
Roof Leak Questions From Building Owners
How do you find a commercial roof leak?
By working backward from the stain. Water enters at a seam, flashing, or drain and then runs along the deck, so the drip inside is often several feet downhill from the opening.
We mark the stain by bay or column line, walk the roof above it, probe seams, check curbs and drains uphill, and use core cuts to see how far the water spread.
Can one section be repaired while the rest of the roof waits?
Yes, when the rest of the roof is dry. Many owners repair the worst section now and plan replacement of the remaining roof for a later budget year. Dated photos from each visit show whether the waiting sections are holding or starting to slip.
How much does commercial roof repair cost?
The price follows what the roof walk finds: how many leak points, whether insulation underneath is wet, the membrane or panel type, and how hard the area is to reach. A single drain reset costs far less than cutting out wet boards around a curb. The free estimate lists each repair separately.
Do you repair metal roofs as well as membranes?
Both. Metal roof repairs cover backed-out screws, dried washers, open laps, rusted panels, and loose curb or wall flashing. Membrane repairs cover TPO, PVC, and EPDM seams, blisters, and flashings. Details for steel roofs are on the metal roofing page.
Can a roof leak be repaired in winter?
Often, with the right products. Cold-weather adhesives and primers exist for EPDM, and TPO welds well when the surface is dry and test welds pass. Frost, dew, and snow on the membrane are the real limits, so winter repairs wait for a dry afternoon.
