Drips Along A Straight Line
An open lap where the seam weld or seam tape let go, common on older TPO and EPDM.
Clean and prime the lap, then weld a TPO patch or apply EPDM cover tape well past the open length.

Low-Slope Membrane Roofs
As a Noblesville flat roof repair contractor, we fix split seams, leaking drains, cracked flashing, and blisters on TPO, EPDM, and built-up roofs.
Noblesville flat roof repair works best while the membrane still flexes and the insulation reads dry outside the leak area.
| Roof Condition | Good Fit For Repair | Points Past Repair |
|---|---|---|
| Membrane | Flexible, seams mostly bonded | Brittle, shrinking, pulling at walls |
| Insulation | Dry beyond the leak spot | Wet across large areas |
| Leaks | Traced to a seam, drain, or flashing | Recurring across many tenant spaces |
| Ponding | One low area near a drain | Water held over much of the roof |
| Past patches | A few, still bonded | Layers of patches over patches |
Each row pairs what you see with the roof detail behind it and the repair that closes it.

A loose clamping ring, a cracked membrane at the bowl, or a strainer packed with debris.
Reset the clamping ring with new flashing into the bowl, clear the leader, and fit a new strainer.
Wet insulation that lost its bond, usually beside an old leak that ran for months.
Cut out the wet board, install dry insulation and cover board, and tie new membrane into the field.
Trapped moisture or air between plies that expands on hot days and splits in winter.
Open the blister, dry and re-adhere the plies, and cap it with matching modified bitumen.
Base flashing that slid or cracked where the membrane turns up the wall or parapet.
Strip the failed flashing, run new membrane up the wall, and secure it under a termination bar.
Flat roofs sit over the most tenant space per square foot, so one repair reaches many people below.
Water that stays two days after rain points to a drain or deck problem. Call and we will check it before it finds a seam.
Membrane repairs follow a set order, because a patch over a wet or dirty surface lets go within a season.
Seams, drains, wall flashing, and curbs get checked across the whole roof, with each soft spot and open lap marked on a roof sketch and photographed.
A moisture meter maps wet insulation around each leak, and a small core cut confirms the reading and shows the layers under the membrane.
Wet board and torn membrane come out to dry, solid edges. Nearby laps get cleaned with the primer or cleaner made for that membrane.
TPO patches are heat-welded and probed; EPDM patches use primer and cover tape; built-up areas get matching modified bitumen.
Where it is safe, water poured near the repair shows it flows to the drain. Photos of the finished patch go into your repair record.
Many flat roofs carry metal sections, curbs, and equipment, so these services often share a visit.

Question about your own roof?
Call UsFix the entry point and the damage it caused. That means removing wet insulation, patching with the same membrane as the roof, and correcting the drainage that sent water there. Sealant brushed over wet material holds for a few weeks at most.
Patches fit a puncture, one split seam, or a single failed flashing on membrane that still flexes. Replacing a section or the roof fits when leaks repeat across tenant spaces or moisture readings show wet board over large areas.
Drain work can mean a new clamping ring or strainer, fresh membrane flashed into the drain bowl, a cleared leader pipe, or tapered insulation so water stops pooling short of the drain. Ice around drains often cracks that flashing over winter.
Membrane type, the size of the damaged area, how much insulation is wet, the number of drains and penetrations involved, and roof access set the price. Every repair gets priced after a free roof walk.
Many repairs can. TPO welding works on a dry, clean surface in cold air, while some adhesives and primers need warmer temperatures. On a cold, wet day we make a temporary seal and return for the permanent patch.
A seam patch or drain reflash usually takes part of a day. Repairs that involve cutting out wet insulation over a larger area take longer, and the repair list tells you the expected length before work begins.
Send the address and where water shows. We will walk the membrane and return photos with the repair list.
