Patch Edges
Patches applied over dirty or wet membrane lift at their edges and let water under. Edges are probed all the way around each patch.

As a Souderton commercial roof repair contractor, we check renewed leaks against earlier patches and fix the true source on plant and shop roofs.

Souderton commercial roof repair on older plant roofs often means reading the roof’s repair history first.
When a leak returns near an old patch, the patch is the obvious suspect. Sometimes it failed at its edge, and sometimes a wall, a curb, or nearby equipment is letting water in instead.
We compare where and when the new leak shows up with the old repair, inspect the patch boundary, and check the details around it. The scope says which one failed. Past repair notes help, if you have them.
Souderton plant and shop roofs with repair history leak from these five places.
Patches applied over dirty or wet membrane lift at their edges and let water under. Edges are probed all the way around each patch.
Layers of mismatched patch material crack where they overlap and trap water between them. Overlaps between mismatched materials are cut out and rebuilt.
Food and manufacturing vents leave residue that breaks down nearby flashing and membrane. Residue is cleaned off before any new flashing goes on.
Walls above older roof sections absorb water and pass it behind the base flashing. Wet masonry above a roof often stains the ceiling near the wall.
Equipment added over the years sits on curbs flashed by different crews to different standards. Curbs flashed with different materials get one consistent detail.

Checking a leak against past repairs keeps money from going into the wrong patch again.
Old patches that lifted are cut out and replaced with matching membrane on clean roof. Patch edges are rolled tight so water cannot creep under them.
Walls, vents, and curbs near the old patch get checked, so a new entry point is caught. Walls are checked even when the old patch looks failed.
Repairs are staged with plant staff around lines, vents, and sanitation needs. Plant sanitation rules are followed for any work above food areas.
Each visit adds to a marked sketch of every repair on the roof. The sketch stays with the building for the next visit.

Answers for Souderton plant and building owners.

Compare where and when the new leak shows up with the earlier repair before assuming the same defect is back. We inspect the patch edge and nearby details, including walls and equipment, to tell a failed repair from a new source.
Whether old patches must come out, how much wet material sits under them, curb and wall work, and access around plant equipment. The written scope locates each item.
Yes. Work near process vents and over production areas is planned with plant staff, including protection below and any cleaning steps the plant requires.
We do, from our Allentown base. Souderton is part of our regular service area for plant, shop, and office roofs.
Dates, locations, and materials of past repairs make the next leak faster to trace and show whether one area of the roof keeps failing. Keep the sketch with the building file.
Grease, steam, and residue from food or manufacturing vents break down membrane and patch adhesives around the vent. Repairs there use material suited to that exposure and get checked on each visit.
Send the address and any notes on past repairs. We find out whether the old patch failed or something new is leaking.
