As an Indianapolis flat roof repair contractor, we weld, tape, and reflash low-slope membranes where water gets in, then check the drains that feed it.
Indianapolis flat roof repair fits when the membrane is still attached and the wet area has an edge. Here is how the two cases compare.
One or a few problems on a membrane that still bends without cracking.
A membrane that fails faster than it can be patched.
Low-slope roofs give plenty of warning before a ceiling comes down. These are the ones we see most on Indianapolis offices and warehouses.
Probing the lap with a seam tool finds a gap where the weld or tape let go.
Dirt rings show where ponds stood for days and wore the membrane surface thin.
Trapped moisture pushes the plies apart into soft bubbles that split under foot traffic.
Debris enters the drain body, and water slips under a loose clamping ring.
Flashing that pulls down from the wall leaves an open top edge for rain.
Spongy areas mean the insulation below has soaked up water and lost strength.
Each problem gets the repair that matches the membrane on the roof. We confirm the membrane type before ordering material.
| Problem | What We Repair | Material |
|---|---|---|
| Split or lifted seam | Clean, prime, and weld or tape a cover strip over the lap | Matching TPO, EPDM, or mod bit |
| Ponding water | Clear drains, replace crushed boards, add tapered crickets | Tapered insulation and new membrane |
| Leaking drain | Reset the clamping ring and flash the membrane into the bowl | New drain parts and target patch |
| Puncture or blister | Cut out the damaged area and patch with overlap on dry roof | Same membrane as the field |
| Wall flashing | Reattach flashing, add termination bar, seal the top edge | Termination bar and counterflashing |
A good flat roof repair closes the leak and stops the damage that follows it.
Cutting out wet insulation keeps rot and rust off the deck below the patch.
Cleared drains and crickets move rain off before it can stand in rings.
Welded cover strips tie into the field membrane instead of sitting on top of it.
Moisture readings mark the edge of the repair so the patch covers the full wet area.
Standing water on a flat roof usually traces back to one drain or one low spot. We find which, then repair it.
Schedule Your Free InspectionA flat roof repair follows the water from the drip to the detail that let it in.
Drains, scuppers, and strainers get cleared and inspected, since a backed-up drain causes many flat roof leaks.
Laps near the leak and the wall flashing above it get probed for gaps and loose termination bar.
Moisture readings set the edges of the patch so no soaked insulation stays under new membrane.
Wet boards come out, new insulation goes in, and a matching membrane patch is welded or adhered over it.
The new seams get checked and photographed, and you receive the photos with a note on any other weak spots.
Flat roofs often share a building with metal sections, rooftop units, and plant equipment.
An office with a flat roof may have a metal canopy or warehouse wing whose screws and laps need attention too.
Typical Repairs
When the drip inside sits far from any obvious seam, the leak tracing service follows the water to its entry point.
Typical Repairs
Plant roofs with exhaust fans and grease need curb flashing chosen for what the fans discharge.
Typical RepairsWhat owners ask about flat and low-slope roofs before we start a repair.
Heavy rain raises the water level on the roof until it reaches a weak spot that light rain never touches. That spot is often a split seam low on the roof, open wall flashing, or a drain clogged enough to let water stack up. We check those three places first.
It starts with finding why the water stays. A blocked drain gets cleared and reset; crushed or wet insulation gets replaced; a low area gets tapered insulation or a cricket to push water toward the drain. The membrane over the repaired area is then patched to match the field.
A patch fits a puncture, a split seam, or one failed flashing on membrane that still bends and stays attached. When patches keep multiplying and the moisture scan shows wet insulation across large areas, a section replacement makes more sense. The scan decides it, and you see the readings.
Ice in a drain bowl can lift the clamping ring and crack the flashing around it. We replace cracked drain parts, reset the clamping ring, flash the membrane back into the bowl, and clear the line. Repairs that need adhesive are timed for days warm enough for it to bond.
We repair TPO, EPDM, PVC, modified bitumen, and built-up roofs. Each one takes its own patch material: hot-air welding for TPO and PVC, seam tape and primer for EPDM, and torch-free cold or heat-applied patches for asphalt roofs. Matching the membrane keeps the repair from peeling at its edges.
Tell us where the water shows and what the roof is made of. We inspect it and price the repair before starting.
