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.
