Single Ply Roofing

Single Ply Roofing

Single ply roofing is a single layer of roofing material. It is a flexible or semi-flexible pre-manufactured membrane typically made of rubber or plastic materials.

The term single ply roofing can be used to describe a few different kinds of roof assemblies, from modified bitumen to PVC. Primarily this term is used to describe newer roof membranes such as:

  • TPO (Thermoplastic Polyolefin) is a high quality, reinforced membrane with superior tear strength and stability
  • PVC (Polyvinyl Chloride) is an energy efficient, fiber-reinforced, lightweight roof membrane
  • EPDM (Ethyl Propylene Diene Monomer) is an elastomeric rubber roofing membrane

PVC and TPO membranes are both thermoplastic sheets, which means that they can be heat welded. The welded seams of a properly installed thermoplastic membrane are usually stronger than the sheet itself.

Both PVC and TPO membranes are usually white although many manufacturers are now offering these in a variety of colors. The white sheets have benefits due to their reflective nature. Many testing and certification entities have labeled these as being"cool roofs" due to their ability to lower interior temperatures and utility costs as compared to a darker roof type.
