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 Rochester, MN.
We coordinate Rochester scheduling around your business hours whenever the situation allows.
Written Flat Roof Repair estimates cover membrane type, repair scope, and labor upfront.
Hot-air welders and seam probes come standard for TPO and EPDM Flat Roof Repair work.
Most Rochester 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.
We identify the membrane type first, since EPDM and TPO repairs use different adhesive systems.
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.
Clogged or damaged drains are a leading cause of Rochester flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Rochester commercial roof leaks that general roofers often overlook.
We start by discussing the issue — ponding, active leak, or visible membrane damage.
A technician inspects the membrane system, checking seams, drains, and any ponding areas.
Drainage and ponding issues are assessed alongside any visible membrane damage.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.
TPO seam repair was clean, tested it before leaving to make sure it actually held.
