Single Ply Roofing System
Florida Single ply roofing membranes are factory-manufactured membranes that are sheet-like. There are two types of single-ply membranes: thermoplastic or thermoset. Thermoplastic materials can be softened when heated and hardened when cooled.
Single-ply roofing membranes are produced using one of three manufacturing processes:
- spread coating.
Thermoplastic Olefin (TPO Roofing) Thermoplastic Olefin, better know as TPO, sheets are a blend of polypropylene and ethylene propylene polymers and usually are reinforced with polyester. TPO sheets contain colorant, flame retardants, UV absorbers and other proprietary substances to achieve desired physical properties. TPO membranes usually come in white or black.
Ethylene Propylene Diene Monomer (EPDM) Thermoset membranes incorporate principal polymers that are chemically cross linked or cured. One characteristic of true thermoset polymers is once they are cured, they only can be bonded to simliar materials with adhesives.
The most common thermoset roof membrane is EPDM. EPDM principally is composed of two compounds, ethylene and propylene, that are derived from oil and natural gas.
Contractors commonly call these membranes “rubber” roofs.
Benefits of Single Ply Roofing System
- White reflective Cool Roof surface helps reduce cooling energy costs
- Heat welded seams are stronger than the membrane itself
