What is Single Ply Roofing?

Single Ply Roofing is a lightweight roofing system which is very economical service and best suited for retro-roofs. Paiva Consulting will help you chose the best roofing membrane to suit your roofing needs, the membrane choices are:

  • Lightweight
  • Best for retro-roofs
  • Easy to install
  • Cost effective

Thermo Plastic Olefin (TPO)

TPO-based products have been used in various applications, including the automobile industry since the 1980s, and have seen their usage continue to expand. In 1989, TPO-based membrane moved into the roofing industry as a non-reinforced sheet. In 1993, the original non-reinforced TPO membrane was replaced with membranes containing reinforcing fabric. Since that time, the TPO single-ply roofing market has grown to hundreds of millions of square feet annually with TPO membrane comprising the fastest growing segment of the U.S. and Canadian single-ply roofing industry. Unlike some other popular thermoplastic roofing membranes, the TPO polymer does not contain chlorine and no chlorine-containing ingredients are added during the sheet production. This lack of chlorine has allowed TPO marketers to tout their membrane as an environmentally safe, “green” product. It does not produce any dioxins or chlorine. The TPO resin is compounded with other components including a weathering package, fire retardants and pigments for color to create a product that can withstand the elements associated with rooftop exposure. It comes in a large variety of thicknesses and roll widths.

Ethylene Propylene Diene Monomer (EPDM)

EPDM is excellent for extreme temperatures, it is UV radiation and ozone resistant. It also contracts and expands as needed. ¬†It requires minimal maintenance and has a lifespan of approximately 30-years. The EPDM membrane is installed loose laid. Perimeter securement is mechanically fastened along the perimeter and at penetrations. Large rolls of EPDM can be laid out at one time significantly reducing application time and splices in the membrane. EPDM membrane comes in common thickness of forty-five mils (0.045″) and sixty mils (0.060″). Thicker membranes up to one hundred mils (0.100″) are available from most manufacturers. ¬†Structural integrity is important with loose-laid roof systems. E.P.D.M. ballast systems are among the heaviest weight roofing systems available. Learn more about EPDM

Polyvinyl Chloride (PVC)

Typical BUR system incorporate pea stone gravel surfacing embedded into an application of hot asphalt or cold adhesive. The gravel provides the roofing system with ballast and acts as an protective layer to reduce the effects of heat, UV degradation and moisture, which can degrade the asphalt systems very quickly. The gravel also provides protection against foot traffic.
