Pros to TPO Roofing

  • Energy efficiency: The material used for Modified roofing does not absorb as much heat as other materials which makes for less strain on air conditioning units and keeps homes and businesses cool during warmer months. 
  • Durability: Formulated to remain flexible, Modified is less likely to crack or form leaks during cold fronts. 
  • Versatility: Used in both residential and commercial applications, Modified is often used in conjunction with other roofing materials to produce an aesthetically pleasing visual as well as an efficient solution to roofing needs.
  • Safety: Modified variations can be rated up to Class A fire rating.
  • Environmentally friendly: When recycled appropriately, Modified is a great alternative to traditional roofing materials as its recyclable qualities allow for less waste.

Cons to Modified Roofing

  • Price: Modified is in the mid-range of investments when compared to other roofing options.
  • Cold Installation: Due to its fragility in heat, damage can be done by too much foot traffic occurrence when installed in high temperatures
  • Strong Odor: During the time of installation, a strong odor can be detected depending on how much space was covered.
