Single-Ply Roof Systems
Single-ply roof materials are generally referred to as elastomeric systems, which are either thermoplastic or thermosetting in nature. Thermoplastic materials are readily formed or changed in shape upon the application of heat. Thermosets are not changed in shape by the application of heat.
Single-ply membranes are installed by using:
Loose laid Ballasted – Minimum 10 pounds per square foot of stones are distributed over the membrane to resist the forces of wind.
Fully Adhered – Adhesive is used to hold the roof membrane to the structure.
Mechanically Attached (Mechanically Fastened) – Mechanical anchor (fastener) from through the membrane into the deck.
