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.
We also test repaired seams for a proper bond before leaving, rather than assuming a visual check is enough.

Here's what falls under our Portland Flat Roof Repair service for commercial and low-slope roofs.
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.
We identify why water is pooling — often a low spot or blocked drain — before recommending a solution.
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.
