Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Johnson City, 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 Johnson City commercial property.
Local Johnson City dispatch minimizes business disruption with scheduling around your operating hours.
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.
Most Johnson City 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.
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 Johnson City flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Johnson City 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.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.

Ponding water on our building had been an issue for years until they actually fixed the drainage instead of just patching around it.
