Flat and low-slope roofs fail differently than pitched shingle roofs — ponding water, seam separation, and membrane punctures need specialized diagnosis.
Our Flat Roof Repair technicians are trained specifically on membrane systems, not general shingle repair applied to a low-slope roof.
We also test repaired seams for a proper bond before leaving, rather than assuming a visual check is enough.
Every Flat Roof Repair technician carries current Granite City, IL licensing for commercial roofing work.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
Membrane type and repair scope are itemized separately in every Flat Roof Repair estimate.
Hot-air welding equipment ensures a proper bond on every TPO Flat Roof Repair repair.
Here's what falls under our Granite City 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.
EPDM punctures and seam failures are patched with compatible materials, not a mismatched quick fix.
We identify why water is pooling — often a low spot or blocked drain — before recommending a solution.
We assess whether a modified bitumen repair needs a patch or a full section replacement.
Clogged or damaged drains are a leading cause of Granite City flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Granite City commercial roof leaks that general roofers often overlook.
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.
Drainage and ponding issues are assessed alongside any visible membrane damage.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.
TPO seam repair was clean, tested it before leaving to make sure it actually held.
