Roof Repair Smedway's Flat Roof Repair crews are trained on TPO, EPDM, and modified bitumen systems across Grantham, 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 Grantham business operations.
Insurance documentation available before work begins on any Grantham commercial property.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
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 Grantham flat roof issues combine two or three of these elements, which is why a full inspection matters.
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 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 Grantham commercial roof leaks that general roofers often overlook.
