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.
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 Denville, NJ licensing for commercial roofing work.
Local Denville dispatch minimizes business disruption with scheduling around your operating hours.
No surprise costs once we're already on the roof mid-repair.
Hot-air welding equipment ensures a proper bond on every TPO Flat Roof Repair repair.
Here's what falls under our Denville 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.
We assess whether a modified bitumen repair needs a patch or a full section replacement.
Clogged or damaged drains are a leading cause of Denville flat roof ponding and membrane stress.
Rooftop HVAC units and their curbs are a frequent source of Denville commercial roof leaks that general roofers often overlook.
We start by discussing the issue — ponding, active leak, or visible membrane damage.
A technician inspects the membrane system, checking seams, drains, and any ponding areas.
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.
TPO seam repair was clean, tested it before leaving to make sure it actually held.
