Flat and low-slope roofs fail differently than pitched shingle roofs — ponding water, seam separation, and membrane punctures need specialized diagnosis.
Our Flat Roof Repair technicians are trained specifically on membrane systems, not general shingle repair applied to a low-slope roof.
We also test repaired seams for a proper bond before leaving, rather than assuming a visual check is enough.

Hot-air welders and seam probes come standard for TPO and EPDM Flat Roof Repair work.
Most Walnut 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.
We assess whether a modified bitumen repair needs a patch or a full section replacement.
We clear and repair drains and scuppers as part of a full Flat Roof Repair visit.
We reseal and reflash equipment curbs as part of a thorough Flat Roof Repair inspection.
