Welded connections
A seam joins adjacent membrane sheets into a continuous covering. Repair and new seam work require the appropriate preparation and weld conditions, with quality checks suitable for the system.

TPO is a thermoplastic single-ply membrane with heat-welded seams. The finished roof includes much more than its open white field: perimeter attachment, seams, roof penetrations and equipment curbs form the complete water barrier.
A repair needs a suitable surface and compatible material. The age and condition of the existing membrane, contamination, attachment and the underlying insulation help determine the work.

A seam joins adjacent membrane sheets into a continuous covering. Repair and new seam work require the appropriate preparation and weld conditions, with quality checks suitable for the system.
Curbs, pipes and roof edges need their own compatible flashing and attachment details. A strong field membrane cannot compensate for a disconnected transition or loose edge.
The membrane, substrate, insulation condition and attachment are evaluated together. Wet or unsound layers affect repair, recover and replacement options.
The roof’s route to drains or scuppers and the connections around equipment are part of the scope. Replacing open field membrane alone can leave the cause of leaks in place.
System instructions govern preparation, welding and weather limitations. Access, staging and protection of occupied areas are planned for the actual building.
No. PVC and other systems can also be white. The existing membrane must be identified before selecting a repair method.
Membrane thickness is one product choice. The attachment, insulation, drainage, seams and details affect the complete roof system.
Yes, when the existing membrane condition and compatible repair details support it. Moisture and substrate problems can widen the scope.
