Flat and low-slope roofs fail differently than pitched shingle roofs — ponding water, seam separation, and membrane punctures need specialized diagnosis.


A flat roof leak rarely shows up directly above where the water actually entered — membrane systems move water laterally before it drips through.
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 Otis commercial property.
Local Otis dispatch minimizes business disruption with scheduling around your operating hours.
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 Otis 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.
Standing water that doesn't drain within 48 hours accelerates membrane breakdown and needs a drainage fix, not just a patch.
Modified bitumen blisters and seam issues are repaired using proper torch-down or cold-adhesive technique depending on the situation.
Clogged or damaged drains are a leading cause of Otis flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Otis commercial roof leaks that general roofers often overlook.

We start by discussing the issue — ponding, active leak, or visible membrane damage.
Technicians identify your membrane type before recommending any Flat Roof Repair repair method.
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.
