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


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 Gurnee commercial property.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
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 Gurnee 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.
We assess whether a modified bitumen repair needs a patch or a full section replacement.
Clogged or damaged drains are a leading cause of Gurnee flat roof ponding and membrane stress.
We reseal and reflash equipment curbs as part of a thorough Flat Roof Repair inspection.

We start by discussing the issue — ponding, active leak, or visible membrane damage.
On-site assessment identifies the membrane type and the actual cause of the issue.
Repair scope and pricing are explained clearly so you can plan around business operations.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.
