Flat and low-slope roofs fail differently than pitched shingle roofs — ponding water, seam separation, and membrane punctures need specialized diagnosis.


A flat roof leak rarely shows up directly above where the water actually entered — membrane systems move water laterally before it drips through.

Most Concrete flat roof issues combine two or three of these elements, which is why a full inspection matters.
TPO seam separation gets properly heat-welded, not just caulked over as a temporary fix.
EPDM punctures and seam failures are patched with compatible materials, not a mismatched quick fix.
Standing water that doesn't drain within 48 hours accelerates membrane breakdown and needs a drainage fix, not just a patch.
