Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Duluth, not general shingle work applied to a flat surface.
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.
Insurance documentation available before work begins on any Duluth commercial property.
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.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Most Duluth flat roof issues combine two or three of these elements, which is why a full inspection matters.
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 Duluth flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Duluth 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.
Repair scope and pricing are explained clearly so you can plan around business operations.
Repaired seams are tested for a proper bond before we leave the site.
TPO seam repair was clean, tested it before leaving to make sure it actually held.
