Low-Slope Roofs
Our Fort Wayne flat roof repair work fixes the drains, seams, and blisters that let water into membrane roofs.
Fort Wayne flat roof repair makes sense when the wet area is contained. These five checks tell the two cases apart.
This Service
The membrane holds across most of the roof and the leak comes from a detail.
Larger Project
Water has worked under a large share of the membrane and keeps finding new paths.
Low-slope membrane roofs fail at a short list of places. These six bring most of the calls.
A loose clamping ring or cracked bowl lets water slip between the drain and the membrane flashing.
Low spots near drains hold water for days, wearing the surface and freezing in winter.
Welds and taped laps open along their edges, often where people walk to rooftop units.
Trapped moisture swells under the top plies in summer heat until the blister cracks open.
Wind gets under a loose edge strip and starts peeling the membrane back from the roof edge.
Flashing at unit curbs cracks at the corners, sending water straight down the curb wall.
What the roof looks like when we arrive, and what it looks like when the repair is finished.
Before The Repair
After The Repair
Call before the next freeze. Standing water around a drain is easier to repair before ice forms in it.
A flat roof repair is only as good as the dry insulation under it, so moisture comes first.
Each drain is opened, each seam along the main walkways is probed, and every curb gets a close look. Blisters and patches are marked on a sketch of the roof.
Meter readings across the suspect area, confirmed with a core cut, show where the boards hold water. That outline becomes the cut-out line for the repair.
Saturated insulation comes out down to the deck, and the deck is checked for rust or rot before anything goes back.
New board goes in, then TPO is welded, EPDM is taped and primed, or built-up plies are laid to tie into the old roof. Drains get new flashing and clamping rings.
Every new weld is probed, and drains get water run through them where we can. Photos of the finished repair go to you with the list.
Flat roof calls often turn up a second problem. These are the usual neighbors.
Loose fasteners, open laps, and rusted panels on metal buildings.

Industrial Roof Repair detailsThe strainer comes off, debris is cleared, and the old flashing is cut back. Then the clamping ring is reset or replaced and new membrane is flashed into the bowl. If water collects around the drain, tapered insulation builds up the low spot.
Membrane type, the amount of wet insulation to replace, how many curbs and drains sit in the repair area, and access to the roof. Detail work at parapets and units takes longer than open field areas. The price is set on site after moisture readings.
Find the water path, remove whatever is wet, and repair with the same family of material as the roof. A heat-welded TPO patch on TPO, primed tape on EPDM, and compatible plies on built-up roofs hold far longer than mastic over a mismatched sheet.
Small blisters that stay closed are watched and noted. Large ones, cracked ones, and blisters in walkways get cut open, dried, and covered. A roof covered in blisters points to wet insulation or weak adhesion, which a moisture survey sorts out.
Long runs with few drains hold water, which wears the membrane and fills drains with debris. Dock canopies and wall transitions leak at the flashing, and foot traffic punctures single-ply near units. Details get fixed first, then drainage.
A frozen drain stops meltwater, so it spreads and rises over flashing edges or sits on seams. Repairs target the drain flashing and the low spot around it, and some owners add heat trace to drains that freeze every winter.
Part of it can. Heat-welded TPO patches and mechanically fastened details go on in the cold, while adhesives, primers, and some tapes need warmer surfaces. Active leaks get a temporary cover first, and the adhesive work follows on a milder day.
Most failed patches sit on wet insulation or use the wrong material. Mastic smeared on TPO, or EPDM tape over a dirty seam, loses its grip within a season. Cutting out the wet board and matching the membrane fixes both causes.
