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 Doty, WA licensing for commercial roofing work.
We coordinate Doty scheduling around your business hours whenever the situation allows.
Written Flat Roof Repair estimates cover membrane type, repair scope, and labor upfront.
Hot-air welding equipment ensures a proper bond on every TPO Flat Roof Repair repair.

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.

We clear and repair drains and scuppers as part of a full Flat Roof Repair visit.
