Flat and low-slope roofs fail differently than pitched shingle roofs — ponding water, seam separation, and membrane punctures need specialized diagnosis.


We carry compatible repair materials for multiple membrane brands, since mismatched patch material is a common cause of repeat flat roof failures.
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 Arch Cape commercial property.
We coordinate Arch Cape scheduling around your business hours whenever the situation allows.
No surprise costs once we're already on the roof mid-repair.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Here's what falls under our Arch Cape 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.
We clear and repair drains and scuppers as part of a full Flat Roof Repair visit.
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.
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.

Ponding water on our building had been an issue for years until they actually fixed the drainage instead of just patching around it.
