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 Greenbrae, CA.
We match the repair method to the actual membrane installed, not a generic patch approach that works on none of them well.
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.
Interior water stains on a flat roof rarely sit directly under the actual leak; water travels along the deck before dripping through.
If your Flat Roof Repair situation doesn't fit neatly into one of these categories, call anyway, chances are we've handled something close to it before in Greenbrae.
TPO seam failures get heat-welded rather than caulked, since caulk alone won't hold under thermal cycling.
Adhesive-seamed patches and seam tape repairs address punctures and failed seams on EPDM rubber membrane systems.
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.
