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 McKenna commercial property.
Local McKenna dispatch minimizes business disruption with scheduling around your operating hours.
Written Flat Roof Repair estimates cover membrane type, repair scope, and labor upfront.
Hot-air welding equipment ensures a proper bond on every TPO Flat Roof Repair repair.
Here's what falls under our McKenna Flat Roof Repair service for commercial and low-slope roofs.
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.
Standing water that doesn't drain within 48 hours accelerates membrane breakdown and needs a drainage fix, not just a patch.
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 McKenna 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.
Repair scope and pricing are explained clearly so you can plan around business operations.
A completed Flat Roof Repair includes a walkthrough of what was repaired and why.
