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.

Here's what falls under our Lewiston Flat Roof Repair service for commercial and low-slope roofs.
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 Lewiston flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Lewiston commercial roof leaks that general roofers often overlook.
Commercial Flat Roof Repair visits are scheduled around your operating hours whenever the situation allows.
On-site assessment identifies the membrane type and the actual cause of the issue.
