Single-Ply

Single-ply roofing systems are composed of insulation, a single-ply membrane, flashings, and adhesive. TPO, EPDM, and PVC are the three most common types of single-ply membrane systems. Since they consist only of a single layer of roofing over insulation, these popular systems are lightweight, making them an ideal choice for new or retro-roofs.

TPO (ThermoPlastic Olefin) roofing systems combine the long-term durability of rubber  with the security of hot air welded seams. TPO’s advantages include:

• The most environmentally friendly of the single-ply systems
• Produce no dioxins or chlorine
• Come in varying thicknesses and roll widths to meet your specific requirements.

EPDM (Ethlyene Propylene Diene Monomer) is a stable roofing alternative that withstands extremes of temperature and expands and contracts with the building. Key advantages are:

• Minimal maintenance
• Resistant to UV radiation and ozone
• Proven effective for more than 30 years.

PVC (Polyvinyl Chloride) Roofing Systems are among the easiest single-ply roofing membranes to install and heat-weld together. Among the advantages PVC systems provide:

• Ability to resist various chemical effluents
• Superior resistance to punctures and tears
• Especially suited for roofs that are exposed to concentrations of grease, oils and many kinds of fuels
• Ideal in areas where acid rain or other forms of acidic outflow is a problem.
