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.
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 Lake in the Hills commercial property.
We coordinate Lake in the Hills scheduling around your business hours whenever the situation allows.
No surprise costs once we're already on the roof mid-repair.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Here's what falls under our Lake in the Hills Flat Roof Repair service for commercial and low-slope roofs.

EPDM punctures and seam failures are patched with compatible materials, not a mismatched quick fix.
