Ponding Around Drains
Water that rings a drain for days means the drain sits higher than the deck around it, or the strainer is packed with leaves and grit. The membrane under that ring wears out first.

Is Lafayette Flat Roof Repair Right for Your Roof?
Use this table to see where Lafayette flat roof repair fits and where the cores point toward a bigger job.

| Seams | One or two lifted laps | Laps opening along whole runs |
| Membrane | Flexible, takes a weld or bond | Brittle, cracked, or shrinking from the edges |

| Drains | Clogged strainer or loose clamping ring | Drain sitting high with wide ponding around it |
| Leak pattern | One source you can point to | Stains appearing in several rooms at once |
Flat Roof Repair Calls From Lafayette Offices and Warehouses
Six conditions account for most of the flat roof work we do in town.
Lifted Lap Edges
Heat-welded and taped laps both open with age. A lifted edge lets wind drive rain under the sheet, and the wet spreads along the insulation board before it ever drips.
Blisters In Built-Up Layers
Trapped moisture turns to vapor on sunny days and pushes up bubbles in modified bitumen and older built-up roofs. A blister that cracks open becomes a direct path for water.
Loose Edge Metal
Gravel stops and coping strips hold the membrane edge down. Once the nails back out or the metal bends in wind, the perimeter flaps and the first row of seams starts to fail.
Old Patches Letting Go
Mastic patches and tape fixes from years past dry out and curl. Water slips under their edges, and a patch made from the wrong material seldom bonds to the roof beneath it.
Split Flashing At Walls
Base flashing climbs walls, curbs, and parapets. Shrinking membrane pulls it away at the corners, opening a gap that heavy rain fills faster than the drains can empty it.
Benefits of Flat Roof Repair for Lafayette Building Owners
Repairing the flat roof you have keeps the dry parts working and spends money only where the leak is.
Smaller Openings In The Roof
Moisture readings outline the wet board, so the cut stays tight to the damage. A smaller opening means less exposure to rain during the work and less new material to buy.
Matched Material, Lasting Bond
TPO is welded to TPO, and EPDM is joined with EPDM primer and seam tape. Matching the system lets each new seam bond the way the original roof did.
Drains That Carry Water Again
Resetting a clamping ring, replacing a broken strainer, and lowering a high drain sends water off the roof instead of leaving a pond that ages the membrane.
A Clear Record For Planning
Photos of each seam, drain, and wall flashing show what was fixed and what to watch, so the next roof budget starts from facts on the roof.

How Flat Roof Repair Runs on a Lafayette Roof
Each flat roof repair follows the same four steps, sized to the damage the cores show.
Check Moisture First
Before cutting anything, we take meter readings across the roof and pull a few cores near the leak. The readings mark how far wet board runs under the membrane.
Cut Out The Wet Area
Damaged membrane and wet insulation come out in a clean rectangle. New board goes in at the same thickness, so the patch sits flush with the roof around it.
Weld Or Bond The Patch
New membrane overlaps dry, firm roof by several inches on every side and is welded, taped, or torched to match the system already in place.
Water-Test The Repair
Seams are probed with a hand tool, drains are run with a hose, and photos of the finished patch go into the report you keep.
Other Repairs on the Same Building
Flat roofs often share a building with metal sections, rooftop units, and process equipment.
Commercial Metal Roof Repair
Metal additions, canopies, and sheds next to a flat roof leak at screws and laps. We reseal those laps and swap rusted panels to match.

Commercial Roof Leak Repair
If a stain inside lines up with nothing you can see on the membrane, we trace the water from the ceiling back to its opening.

Flat plant roofs with fans, stacks, and long curb runs get flashing and residue repairs planned around production shifts.

Choosing The Repair
Flat Roof Patch vs Replacement: Which Do I Need?
A patch handles one puncture, one open seam, or one failed flashing on a roof that is otherwise dry. Brittle or shrinking membrane, leaks in many rooms, or wet board across large areas point to replacement. A moisture survey and a few cores show how much of the roof is still dry.
What Is the Best Way to Repair a Flat Roof?
Match the roof that is there. TPO gets heat-welded TPO, EPDM gets EPDM with seam tape, and modified bitumen gets compatible torch or cold-process material. The area is cleaned and primed, wet board is replaced, and the patch runs well past the damage. Mixed materials cause many repeat leaks.
Drains And Ponding
How Does Flat Roof Drain Repair Work?
We work on the strainer, the clamping ring, the drain bowl, and the membrane flashing around it: broken strainers replaced, rings reset or replaced, membrane re-flashed into the bowl, and clogged lines cleared. A drain sitting above the roof around it is lowered, or the area is built up, so water reaches it.
How Is Ponding Fixed on Research Park Roofs?
First we find the cause: a high drain, insulation crushed by foot traffic, or a deflected deck. Then drains are lowered or cleared, crushed board is replaced, and tapered insulation or crickets steer water to the drains. Over labs and offices, only a small area is opened at a time.
Cost And Seasons
What Changes Flat Roof Repair Cost?
The roof system, the size of the damaged area, how much wet insulation comes out, the number of drains, curbs, and flashings involved, roof height and access, and whether the old membrane still accepts a patch. Grouping repairs into one visit lowers the trip cost. The free estimate follows a roof inspection.
How Do Freeze-Thaw and Heat Damage Flat Roofs?
Water in a seam or flashing freezes and expands in winter, so small gaps grow into leaks by spring. Summer heat softens and blisters older membranes and dries out sealant at penetrations. Both hit seams, flashings, and drains, which is why spring and fall checks catch damage early.
