Flat roofs waterproofed with single-ply membranes (PVC, TPO, EPDM) are gaining more and more ground compared to the old bituminous membranes. Due to their multiple positive characteristics, single-ply membranes convince more and more building owners to choose them.

Per trusted commercial roofing Colorado Springs CO contractors, here are the most important pros and cons of these roofing solutions:


PVC membranes

  • Complete solution for flat roofs with a high degree of fire resistance
  • Possibility to obtain customized architectural solutions (colors, profiles and roof logos)
  • Easy to handle and install
  • Suitable for different climatic conditions
  • High flexibility
  • Installation without the use of fire sources, only with hot air
  • Ensuring a clean environment
  • Proven performance and durability for 20 years

TPO membranes

  • High chemical resistance
  • Suitable for direct application on substrates such as bitumen, EPS insulation and polystyrene
  • No plasticizers
  • Easy to maintain
  • Easy to handle and install
  • Suitable for use and exposure in severe climatic conditions
  • Environmentally friendly
  • Proven performance and durability for 35 years

EPDM membranes

  • Excellent stability against weather influences, sunlight, acids and caustic solutions
  • Long-lasting flexibility and elasticity
  • Suitable for uneven substrates and waterproofing of green roofs
  • Excellent durability (50 years)


Some of these membranes have seams that make them more vulnerable to leaks than other roof systems. Additionally, even if these membranes are highly resistant, and some of them reflective (TPO), constant exposure to UV rays can degrade the adhesives more quickly.
