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 Sausalito, 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.
Commercial flat roof repairs get scheduled around your operating hours whenever possible, minimizing disruption to tenants or business activity.
Interior water stains on a flat roof rarely sit directly under the actual leak; water travels along the deck before dripping through.
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.
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.
We address the underlying slope or drainage issue causing ponding, not just patch the membrane where it's currently failing.
Penetration points are the most common flat roof leak source, and repairs here get the same membrane-specific attention as field repairs.
Section replacement gets used when patching would leave a larger vulnerable area than a proper tie-in replacement.
