Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Rancho Santa Margarita, not general shingle work applied to a flat surface.


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.
Every Flat Roof Repair technician carries current Rancho Santa Margarita, CA licensing for commercial roofing work.
We coordinate Rancho Santa Margarita scheduling around your business hours whenever the situation allows.
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.
We assess whether a modified bitumen repair needs a patch or a full section replacement.
We clear and repair drains and scuppers as part of a full Flat Roof Repair visit.
Rooftop HVAC units and their curbs are a frequent source of Rancho Santa Margarita 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.

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