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


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 Happy Valley commercial property.
Local Happy Valley dispatch minimizes business disruption with scheduling around your operating hours.
Membrane type and repair scope are itemized separately in every Flat Roof Repair estimate.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Here's what falls under our Happy Valley 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.
We identify the membrane type first, since EPDM and TPO repairs use different adhesive systems.
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.
We reseal and reflash equipment curbs as part of a thorough Flat Roof Repair inspection.

Commercial Flat Roof Repair visits are scheduled around your operating hours whenever the situation allows.
A technician inspects the membrane system, checking seams, drains, and any ponding areas.
Drainage and ponding issues are assessed alongside any visible membrane damage.
Repaired seams are tested for a proper bond before we leave the site.

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