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 Lenni business operations.
Insurance documentation available before work begins on any Lenni commercial property.
We coordinate Lenni scheduling around your business hours whenever the situation allows.
Written Flat Roof Repair estimates cover membrane type, repair scope, and labor upfront.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Here's what falls under our Lenni 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.
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.
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 Lenni commercial roof leaks that general roofers often overlook.
Commercial Flat Roof Repair visits are scheduled around your operating hours whenever the situation allows.
On-site assessment identifies the membrane type and the actual cause of the issue.
You receive a written estimate covering membrane repair or drainage correction before work begins.
