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


We carry compatible repair materials for multiple membrane brands, since mismatched patch material is a common cause of repeat flat roof failures.
Commercial Flat Roof Repair scheduling is built around minimizing disruption to your Mc Lean business operations.
Insurance documentation available before work begins on any Mc Lean commercial property.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.

Here's what falls under our Mc Lean 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.
We identify why water is pooling — often a low spot or blocked drain — before recommending a solution.
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 Mc Lean flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Mc Lean commercial roof leaks that general roofers often overlook.
