Single Ply Membrane Roofing Repair
Weld seam failure or punctures are the usual cause of a single-ply leak, both repaired with the correct hot-air welding technique.
Single-ply membrane roofs most commonly fail at a weld seam that wasn't fully fused during original installation, from puncture damage caused by foot traffic or debris, or at detailing around outlets and upstands. Because these systems rely on properly executed hot-air welding, a repair needs the same technique and equipment to bond correctly.
Sherford Roofing repairs single-ply membrane roofs across Plymouth and Devon, correctly hot-air welding repairs into the existing membrane rather than relying on adhesive patches that don't perform the same way.
Our Process
Inspect Welds & Surface
We check seam welds and the general membrane surface for the specific cause of any leak.
Diagnose the Fault
A failed weld, puncture or detail failure is confirmed before quoting the repair.
Weld the Repair
A compatible membrane patch is hot-air welded into place, properly fusing with the existing sheet rather than just adhering to it.
Test the Weld
The repaired weld is tested to confirm a sound, fully fused joint.
