Insurance documentation available before work begins on any Cosmos commercial property.

Here's what falls under our Cosmos 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.
Clogged or damaged drains are a leading cause of Cosmos flat roof ponding and membrane stress.
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.
You receive a written estimate covering membrane repair or drainage correction before work begins.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.
