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

Every Flat Roof Repair technician carries current Johnston, IA licensing for commercial roofing work.

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.

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 Johnston flat roof ponding and membrane stress.
