Tpo – Thermoplastics

Thermoplastic polyolefin (TPO) single-ply roofing membranes are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance and installation advantages.

As demand increases for heat-reflective and energy efficient roofing systems, TPO single-ply roofing membranes continue to provide exceptional resistance to ultraviolet, ozone and chemical exposure. In addition, white materials are highly reflective of the sun’s radiant heat and may have a high thermal emittance value (a measure of how much of the absorbed radiant energy is given off into the atmosphere).

Because of this expertise, Rocky Mountain Roofing and Restoration, Inc. can provide clients with an array of thermoplastic roofing solutions. Rocky Mountain Roofing and Restoration, Inc. will also 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.

TPO and PVC Roofs 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.

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.
