Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Columbus, 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.
Every Flat Roof Repair technician carries current Columbus, WI licensing for commercial roofing work.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
No surprise costs once we're already on the roof mid-repair.
Hot-air welders and seam probes come standard for TPO and EPDM Flat Roof Repair work.
Flat roof issues cover a specific range of membrane and drainage problems — here's our Flat Roof Repair scope.
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.
We identify why water is pooling — often a low spot or blocked drain — before recommending a solution.
Modified bitumen blisters and seam issues are repaired using proper torch-down or cold-adhesive technique depending on the situation.
Clogged or damaged drains are a leading cause of Columbus flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Columbus 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.
You receive a written estimate covering membrane repair or drainage correction before work begins.
Repaired seams are tested for a proper bond before we leave the site.
