Flat Roofs: How Long Materials Last & How To Extend Their Life

Environmental factors like severe weather and temperature fluctuations will cause commercial roof systems to deteriorate. To get more years out of your roof, follow a consistent roof maintenance schedule and repair any issues the moment they arise. It’s also advisable to explore warranty programs provided by your roofer. Take some time to learn more about different flat roof systems and how you can extend their life.

Single-Ply Flat Roof Systems

Unlike traditional built-up roof systems (BUR), single-ply roofs consist of a single layer of material forming a membrane across the roof. One of the main advantages of single-ply systems is they can be prefabricated before installation. This speeds up the installation process, providing better protection against moisture at vulnerable penetration points. Single-ply roof systems may be attached using ballasts or adhesives, depending on your needs. The most commonly used single-ply materials available today include:

  • PVC. These membranes are incredibly durable and flexible. PVC (polyvinyl chloride) demonstrates impressive resistance to fire, chemicals, and UV rays. They are easy to maintain and repair. For those concerned about the environment, PVC is an excellent option since it’s entirely recyclable. Those with a PVC roof report lower energy costs due to the material’s highly reflective surface as well. Another advantage to a PVC roof is it can be installed on many existing roofs without the need to tear off the old material. The only exception is when a PVC roof is installed onto an asphalt surface. In this case, a layer of separating material will need to be applied. PVC roof systems will often last for 25 years or more.
  • TPO. In the world of single-ply roofing, TPO is a major contender. TPO stands for thermoplastic polyolefin and is fast becoming one of the most popular commercial roofing materials. Sheets of the TPO are laminated with a highly reflective top layer to reflect sunlight. The material’s resistance to oil and fire is another advantage of TPO. One common problem reported with TPO roofs is the material tends to separate at the seams. If properly maintained, a TPO roof system will likely last 20 to 25 years before replacement is needed.
  • EPDM: This rubber-based material is formed from a compound called ethylene propylene diene terpolymer. Created in the 1960s, EPDM continues to be a solid choice for commercial roofing. Easily one of the most reliable materials for a flat roof, EPDM membranes are extremely versatile and can withstand virtually any environment. It’s not unusual for an EPDM roof to last up to 50 years or even longer.
