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


Our Flat Roof Repair technicians are trained specifically on membrane systems, not general shingle repair applied to a low-slope roof.
We also test repaired seams for a proper bond before leaving, rather than assuming a visual check is enough.
Insurance documentation available before work begins on any Waltham commercial property.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
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.
Flat roof issues cover a specific range of membrane and drainage problems — here's our Flat Roof Repair scope.
TPO seam separation gets properly heat-welded, not just caulked over as a temporary fix.
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.
Clogged or damaged drains are a leading cause of Waltham flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Waltham commercial roof leaks that general roofers often overlook.

We start by discussing the issue — ponding, active leak, or visible membrane damage.
On-site assessment identifies the membrane type and the actual cause of the issue.
You receive a written estimate covering membrane repair or drainage correction before work begins.
A completed Flat Roof Repair includes a walkthrough of what was repaired and why.
