Commercial Roofing

These days when selecting a flat roof membrane most business owners and homeowners choose between TPO and EPDM roofing systems. While TPO is relatively newer than EPDM, both options offer unique traits that factor into why you should choose one over the other.
TPO (Themoplastic Olefin) has quickly become Valiant Roofing’s most popular single-ply flat roof solution. In comparison to other materials, TPO is durable, affordable, and offers reflectivity savings. Instead of gluing or fastening the seams, TPO roof systems use welded seams for increased effectiveness and longevity. Also, in contrast to other membranes, TPO does come in various colors which is another reason homeowners are making it an increasingly popular option. 
TPO can effectively handle thermal expansion and contraction which is just one more reason why commercial projects are increasingly utilizing TPO roofing systems.
In conclusion, the following points illustrate why TPO is so often used by Valiant Roofing’s customers.


  • Ideal for residential and smaller commercial projects
  • Reflective and energy efficient
  • Handles thermal expansion and contraction
  • Comes in multiple colors
  • Welded seams for increased effectiveness


EPDM (Ethylene Propylene Diene Terpolymer) has long been the industry standard for single-ply rubber roofing membranes. EPDM is extensively used in new construction and re-roofing projects. By nature of it’s past 50 year history in the U.S., EPDM  is the number one flat roof choice across every demographic. 
While EPDM isn’t as durable as TPO nor does it offer the same reflectivity benefits, it does have several superior characteristics of its own. EPDM is lightweight which makes it quick to install and also affordable. It also offers different installation options including fully adhered, mechanically fastened and ballasted systems. With membrane widths of up to 50′ and lengths of 200′, EPDM can be installed with less seaming than other materials which makes it an extremely popular option for large commercial projects. Finally, EPDM carries warranties up to 30 years and also offers hail and puncture enhancements. 
EPDM may be the best choice for the following reasons:

  • Ideal for large commercial projects due to size and reduction in necessary seaming
  • Multiple installation options including fastened, adhered, and ballasted systems
  • Has both hail and puncture enhancements
  • Warranties up to 30 years which is longer than what is offered by TPO
