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


A flat roof leak rarely shows up directly above where the water actually entered — membrane systems move water laterally before it drips through.
Commercial Flat Roof Repair scheduling is built around minimizing disruption to your Porter business operations.
Every Flat Roof Repair technician carries current Porter, MN 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.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Here's what falls under our Porter 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.
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 Porter flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Porter commercial roof leaks that general roofers often overlook.

Commercial Flat Roof Repair visits are scheduled around your operating hours whenever the situation allows.
Technicians identify your membrane type before recommending any Flat Roof Repair repair method.
Drainage and ponding issues are assessed alongside any visible membrane damage.
Repaired seams are tested for a proper bond before we leave the site.
