We diagnose flat roof leaks by membrane type first, since a TPO seam fix and an EPDM patch use completely different materials and methods.

None of this is generic marketing language. Each point below reflects how Flat Roof Repair jobs actually get handled here in Creve Coeur, MO.
Crews are trained separately on TPO heat-welding, EPDM adhesive seaming, and modified bitumen torch-down repair, since these systems aren't interchangeable.
Standing water after 48 hours signals a slope or drainage problem, not just a membrane issue, and we diagnose accordingly.
We coordinate repair timing with building management to avoid disrupting normal business operations.
We use water testing and seam inspection to confirm the actual leak source before cutting into a membrane, since flat roof leaks often travel before showing up inside.
Every category below is handled by our own Flat Roof Repair specialists, not a generalist crew or a subcontractor, which keeps the diagnosis and the fix consistent.
TPO seam failures get heat-welded rather than caulked, since caulk alone won't hold under thermal cycling.
EPDM repairs use a liquid adhesive and seam tape system specific to rubber membrane, not a general-purpose sealant.
Repairing modified bitumen requires matching the original application method, torch or cold-process, for the patch to properly bond.
We address the underlying slope or drainage issue causing ponding, not just patch the membrane where it's currently failing.
Roof penetrations, vents, HVAC curbs, drains, get resealed or reflashed where membrane separation has opened a leak path.
Where damage exceeds what a patch can address, a full section gets replaced and welded or seamed into the surrounding membrane.
A real person answers, not a script, and gets the essentials needed to send the right specialist for the job. There's no automated phone tree to work through first.
A fully equipped Flat Roof Repair specialist heads out with the tools and materials most likely needed for the job described. Arrival windows stay tight because dispatch is staged locally in Creve Coeur, MO.
You get a clear, written price based on what's actually found, not a phone estimate that changes once someone shows up. Nothing gets touched until you approve the number.
The job isn't done until it's done right, and it's backed by a written guarantee on our workmanship. A final walkthrough confirms everything before we consider the visit complete.
