To install the PCV roof system, JRC’s roofing team welds seams to form a permanent, watertight bond that is stronger than the membrane itself. This gives PVC roofs an edge over other roofing systems, which rely on adhesives, tapes, and caulks to seal the seams.
The PVC is attached to the optional roof board or insulation with one of two methods.
The first is mechanical fasteners, the fastener is placed in the roof board or insulation and screws are placed through the material, in this case PVC and into the fastener.
The second is a full contact bonding adhesive that is attached to the bottom of the PVC and laid down onto the building.
