Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Watertown, 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.
Every Flat Roof Repair technician carries current Watertown, WI licensing for commercial roofing work.
We coordinate Watertown scheduling around your business hours whenever the situation allows.
No surprise costs once we're already on the roof mid-repair.
Hot-air welding equipment ensures a proper bond on every TPO Flat Roof Repair repair.
Here's what falls under our Watertown 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 Watertown flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Watertown commercial roof leaks that general roofers often overlook.

We start by discussing the issue — ponding, active leak, or visible membrane damage.
Technicians identify your membrane type before recommending any Flat Roof Repair repair method.
Drainage and ponding issues are assessed alongside any visible membrane damage.
A completed Flat Roof Repair includes a walkthrough of what was repaired and why.
