Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Sag Harbor, 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.
Commercial Flat Roof Repair scheduling is built around minimizing disruption to your Sag Harbor business operations.
Every Flat Roof Repair technician carries current Sag Harbor, NY licensing for commercial roofing work.
We coordinate Sag Harbor scheduling around your business hours whenever the situation allows.
Written Flat Roof Repair estimates cover membrane type, repair scope, and labor upfront.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Most Sag Harbor flat roof issues combine two or three of these elements, which is why a full inspection matters.
TPO seam separation gets properly heat-welded, not just caulked over as a temporary fix.
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.
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 Sag Harbor commercial roof leaks that general roofers often overlook.
