Firestone Building Products
Low Slope Roofing Systems

Choosing the membrane type for low slope roofing requires many things to be considered:

  • Roof top usage
  • Wind uplift
  • Fire rating
  • Positive drainage
  • Chemical exposure
  • Building codes
  • Structural loading
  • Sustainability & reflectivity
  • Insurance requirements
  • Environmental and safety regulations

Firestone Building Products offers the most complete selection of low slope membranes in the industry.


This synthetic elastomeric membrane has been proving itself for over 40 years. Offered in both unreinforced and reinforced as a black membrane in traditional applications or unreinforced as a white membrane when a highly reflective surface is required, EPDM can be used in ballasted, fully adhered, mechanically attached, and protected membrane systems. Its weatherability and low temperature flexibility make it the ideal choice for the most extreme climates. Platinum EPDM Systems can be warranted up to 30 years.
