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

These are the specific reasons Sammamish customers pick us for Flat Roof Repair work over a general handyman or an out-of-town crew.
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.
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.
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.
Roof penetrations, vents, HVAC curbs, drains, get resealed or reflashed where membrane separation has opened a leak path.
Section replacement gets used when patching would leave a larger vulnerable area than a proper tie-in replacement.
