TPO and PVC Roofing Systems
These non-asphalt based roofing membranes meet “cool roof” standards, reflecting the sun’s rays and helping you maintain cooler interior temperatures. Thermoplastic Polyolefin (TPO) and Poly Vinyl Chloride (PVC) are thermoplastic roof systems that are both white and highly reflective roof membranes. These roofs provide excellent weathering characteristics and are highly resistant to ultraviolet light and most chemicals. The membranes have a reinforced scrim and are puncture and tear resistant. Thermoplastic roofs have outstanding seam strength due to the fact the sheets are welded together using hot air. These types of roof systems are lightweight and well suited for second generation (roof-over) applications.
Florida Quality Roofing will assist customers in identifying State, Federal and Utility company rebates and incentives which may be available as a result of installing these energy efficient roof systems or “cool roofs”.
There are three typical installation methods for TPO and PVC roof systems that provide lightweight and cost-effective solutions:
- Mechanically Attached – The roof membrane is affixed to the structural deck with mechanical fasteners
- Fully Adhered – The membrane is bonded directly to the affixed insulation board or other roofing membrane substrate.
- Point-affixed – Ideal for retrofit installation over metal applications, plates are installed at set intervals and the roof membrane is welded directly to the plates.
EPDM Roof Systems
Ethyline Propolyne Diene Terpolymer (EPDM) is a dimensionally stable membrane that can withstand and resist almost any type of nature-born stress. This single-ply roof membrane, also commonly referred to as a rubber roof system, utilizes carbon black as its the molecular “backbone” which enables it to take on characteristics such as the ability to expand up to 300% yet retain 100% structural memory. EPDM also has excellent weathering resistance and serves as a superb second generation (roof-over) application.
The method of application, insulation value, membrane thickness, warranty structure and term, as well as many other characteristics are considered so that the roof system we install can provide the best roofing solution for you.
EPDM roof systems are typically installed in one of three methods:
- Mechanically attached – This application provides a lightweight, cost-effective solution whereby the roof membrane is affixed to the structural deck utilizing mechanical anchors.
- Fully adhered – The system is applied by bonding the membrane directly to the affixed insulation board or other roofing membrane substrate.
- Ballasted – Using large sheets and 10 to 12 pounds of rock ballast per square foot to hold the membrane in place, this roof system can be the most cost-effective due to the ease and speed of installation. However, this application does require a structural engineer’s approval.
