Single-Ply Roof Systems

Single-Ply Roof Systems


What is single-ply roofing?

Single-ply roofing is wide width sheeting meant for low slope roofs such as on commercial buildings.

TAG Roofing and Exteriors offers three types of single-ply roofing. These prefabricated membranes are manufactured in a factory for quality control to meet your unique low-slope project application requirements.

Single-ply roofs have far fewer seams than asphalt rolled roof systems and do not require dangerous torches or hot asphalt for installation.





TPO (Thermoplastic Polyolefin)

  • ·       The most popular product in commercial roofing, thermoplastic polyolefin (TPO) is the most economical choice in heat-weldable membranes.
  • ·       TPO offers ease of welding for seaming and detailing.
  • ·       Comes in a variety of thickness options to suit a mix of facility applications
  • ·       Proven to flexible for either roof replacement or recovering projects
  • ·       Highly reflective and helps to reduce air conditioning costs.
  • ·       TPO provides LEED credit qualification, is Energy Star rated and Cool Roofing Rating Council approved.

EPDM (Ethylene-Propylene-Diene-Monomer)


·       EPDM membrane provides long-term strength, durability and weatherability.

·       Its black surface can assist with snow melt and heat gain in colder climates.

·       Material elasticity is great for freeze/thaw conditions and hail-prone areas.

·       EPDM can be easily installed without electric-powered tools.

·       Fire resistant

·       Recyclable

·       Qualifies for LEED points

·       Meets ASTM standards for new membranes

PVC (polyvinyl chloride)


·       Good for restaurants, airports and commercial facilities with grease, oil and chemical concerns

·       Long-term roofing solution

·       Highly reflective and able to help reduce air conditioning costs — great for warm, southern climates

·       Qualifies for LEED credit

·       Puncture resistant and strong seam bonding provide waterproofing protection

·       Suitable for new roofing installation or as a cost-effective reroofing solution


  • These commercial roofing systems can be installed with multiple isolation boards under the membrane, which can improve the R-Value and lower energy costs.
  • Typical commercial construction involves a low-slope roof. Our single-ply roofing is designed to allow water to pool without leaking and causing damage.
  • These boards can also be purchased with an engineered pitch on the top side and flat bottom. This makes it possible to transform a flat roof into one with a pitch, which will assist with water management
