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


A flat roof leak rarely shows up directly above where the water actually entered — membrane systems move water laterally before it drips through.
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 Rothsay commercial property.
Local Rothsay dispatch minimizes business disruption with scheduling around your operating hours.
No surprise costs once we're already on the roof mid-repair.
Hot-air welders and seam probes come standard for TPO and EPDM Flat Roof Repair work.
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.
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.
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.
Rooftop HVAC units and their curbs are a frequent source of Rothsay commercial roof leaks that general roofers often overlook.

We start by discussing the issue — ponding, active leak, or visible membrane damage.
A technician inspects the membrane system, checking seams, drains, and any ponding areas.
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.
