Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across De Soto, 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.
Commercial Flat Roof Repair scheduling is built around minimizing disruption to your De Soto business operations.
Insurance documentation available before work begins on any De Soto commercial property.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
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.
Here's what falls under our De Soto 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.
EPDM punctures and seam failures are patched with compatible materials, not a mismatched quick fix.
Standing water that doesn't drain within 48 hours accelerates membrane breakdown and needs a drainage fix, not just a patch.
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 De Soto flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of De Soto commercial roof leaks that general roofers often overlook.

We start by discussing the issue — ponding, active leak, or visible membrane damage.
On-site assessment identifies the membrane type and the actual cause of the issue.
Repair scope and pricing are explained clearly so you can plan around business operations.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.
