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.
Commercial Flat Roof Repair scheduling is built around minimizing disruption to your Lewiston business operations.

Hot-air welders and seam probes come standard for TPO and EPDM Flat Roof Repair work.
Most Lewiston 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.
