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.
Types of single-ply roof system membranes:
PVC (Polyvinyl Chloride) – PVC is the thermoplastic in nature and resists weathering. PVC roof sheets are reinforced and offer good resistance to acids, alkalis, and many chemicals. Normally, PVCs are available in many colors.
EPDM (Ethylene Propylene Diene Monomer) – EPDM is similar to butyl rubber in composition, but has better weather resistance. EPDM is thermoset membrane. It also has good resistance to corrosive chemicals, diluted mineral acids, and vegetable oils. EPDM is not resistant to petroleum products. EPDM is available in plain and reinforced styles.
TPO (Thermoplastc Polyolefin) – TPO roof sheets are reinforced and contain UV stabilizers, fillers, pigments and flame retarders. TPO is weldeble thermoplastic and has good chemicals resistance.
