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.
Every Flat Roof Repair technician carries current Iowa City, IA licensing for commercial roofing work.
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.
Hot-air welders and seam probes come standard for TPO and EPDM Flat Roof Repair work.
Most Iowa City flat roof issues combine two or three of these elements, which is why a full inspection matters.
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 Iowa City 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.
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.
Ponding water on our building had been an issue for years until they actually fixed the drainage instead of just patching around it.
