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

Commercial Flat Roof Repair scheduling is built around minimizing disruption to your Marsteller business operations.
Insurance documentation available before work begins on any Marsteller commercial property.

Here's what falls under our Marsteller 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.
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.
Rooftop HVAC units and their curbs are a frequent source of Marsteller commercial roof leaks that general roofers often overlook.

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.
