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 San Bruno, CA.
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.
Heat-welded patches and seam repairs restore the membrane's watertight seal using the same welding method as original installation.
Adhesive-seamed patches and seam tape repairs address punctures and failed seams on EPDM rubber membrane systems.
Torch-down or cold-adhesive patches restore modified bitumen systems, matched to the original installation method.
Tapered insulation or additional drains get added where standing water is accelerating membrane wear.
Penetration points are the most common flat roof leak source, and repairs here get the same membrane-specific attention as field repairs.
Where damage exceeds what a patch can address, a full section gets replaced and welded or seamed into the surrounding membrane.
