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 Mc Allister, MT licensing for commercial roofing work.
We coordinate Mc Allister scheduling around your business hours whenever the situation allows.
Membrane type and repair scope are itemized separately in every Flat Roof Repair estimate.
Hot-air welders and seam probes come standard for TPO and EPDM Flat Roof Repair work.
Here's what falls under our Mc Allister 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.
We clear and repair drains and scuppers as part of a full Flat Roof Repair visit.
We reseal and reflash equipment curbs as part of a thorough Flat Roof Repair inspection.

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.
Repairs are completed using membrane-appropriate technique, then tested before we consider the job done.
