We also inspect rooftop HVAC curbs and penetrations, since equipment mounts are a common overlooked source of flat roof leaks.


Our Flat Roof Repair technicians are trained specifically on membrane systems, not general shingle repair applied to a low-slope roof.
Commercial Flat Roof Repair scheduling is built around minimizing disruption to your Portland business operations.
Every Flat Roof Repair technician carries current Portland, ME licensing for commercial roofing work.

Hot-air welding equipment ensures a proper bond on every TPO Flat Roof Repair repair.
Here's what falls under our Portland Flat Roof Repair service for commercial and low-slope roofs.
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.
Standing water that doesn't drain within 48 hours accelerates membrane breakdown and needs a drainage fix, not just a patch.
We assess whether a modified bitumen repair needs a patch or a full section replacement.
Clogged or damaged drains are a leading cause of Portland flat roof ponding and membrane stress.
We reseal and reflash equipment curbs as part of a thorough Flat Roof Repair inspection.

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.
Repaired seams are tested for a proper bond before we leave the site.

TPO seam repair was clean, tested it before leaving to make sure it actually held.
