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


We carry compatible repair materials for multiple membrane brands, since mismatched patch material is a common cause of repeat flat roof failures.
We also test repaired seams for a proper bond before leaving, rather than assuming a visual check is enough.
Membrane Flat Roof Repair credentials cover commercial licensing requirements across Marcus, WA.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
Membrane type and repair scope are itemized separately in every Flat Roof Repair estimate.
Hot-air welders and seam probes come standard for TPO and EPDM Flat Roof Repair work.
Most Marcus 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.
Modified bitumen blisters and seam issues are repaired using proper torch-down or cold-adhesive technique depending on the situation.
We clear and repair drains and scuppers as part of a full Flat Roof Repair visit.
Rooftop HVAC units and their curbs are a frequent source of Marcus commercial roof leaks that general roofers often overlook.
