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.

Flat roof issues cover a specific range of membrane and drainage problems — here's our Flat Roof Repair scope.
We test repaired seams for a proper bond before considering the Flat Roof Repair job complete.
We identify the membrane type first, since EPDM and TPO repairs use different adhesive systems.
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.
Clogged or damaged drains are a leading cause of Darrington flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Darrington commercial roof leaks that general roofers often overlook.
