Did You Know? Roof Membranes Did You Know? Roof Membranes

Here are six fast facts you may not know about roof membranes:

  1. Membrane roofing, such as Thermoplastic Polyolefin (TPO), is the newest flat roof technology, while Built-Up Roofing (BUR) is the oldest at over 120 years old!
    TPO roofs provide a wide range of benefits, including flexibility, durability and energy efficiency, and are the second most installed flat roofs in America.
  2. Modified Bitumen, or Mod-Bit roofing, is actually a type of asphalt that is applied to the roof, commonly known as “tar-and-gravel” roofing.
    Mod-Bit roofing has two types, known as atactic polypropylene (APP) and styrene-butadiene-styrene (SBS). While SBS is the most common, both types offer excellent benefits depending on needs.
  3. EPDM has the industry’s longest average service life of approximately 25-30 years.
    EPDM is actually a rubber roof system, and dark in color. EPDM can be installed in 3 different ways, but the most common way to install an EPDM roof system is to have it mechanically attached.
  4. TPO can contain a variety of add-ins to achieve different roofing goals.
    Different add-ins include UV absorbers, colorant and flame retardant.
  5. PVC, or Polyvinyl Chloride, was the first roof membrane to contain half of the fossil fuels previously used in manufacturing, making it a more environmentally-friendly roofing option.
    Plus, PVC membranes are available in a variety of colors, thicknesses and widths and reinforcements, making them a great option for almost any roofing project.
  6. PVC systems can withstand up to 300 pounds per inch.
    This is 100 pounds per inch heavier than the industry average.
