Did You Know? Roof Membranes
Here are six fast facts you may not know about roof membranes:
- 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.
- 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.
- 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.
- TPO can contain a variety of add-ins to achieve different roofing goals.
Different add-ins include UV absorbers, colorant and flame retardant.
- 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.
- PVC systems can withstand up to 300 pounds per inch.
This is 100 pounds per inch heavier than the industry average.
