EPDM is available in black and white and is sold in a broad variety of widths ranging from 7.5 feet to 50 feet and is available in multiple thickness gauges. EPDM can be installed fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.

Modified Bitumen Cap Sheet Roofing System:

This type of roofing is an evolution of asphalt roofing. It is made from asphalt and a variety of rubber modifiers and solvents. There are several ways of connecting pieces of this material. In a heat application process the seams are heated to melt the asphalt together to create a seal. There are also hot mopped and self adhering applications and the sheet is available in a smooth or granulated surface. This material is also referred to as APP, SBS, and SEBS.


Over the last 10-years TPO has overtaken EPDM as the membrane of choice for building owners.
TPO advantages:

  1. Superior reliability – TPO seams are 4 times stronger than taped EPDM.
  2. Easier to install – TPO membranes are installed using half the steps as compared to EPDM, thus less room for error.
  3. Puncture resistant – TPO is up to 3 times more puncture resistant compared to EPDM.
  4. Lower cost solution – The ease of installation saves money on labor.
  5. Energy efficiency – TPO roofs transmit much less solar radiation (versus black EPDM) into your facility, thereby resulting in energy savings.

    "These guys were very professional, they finished their work in one day, and had a dedicated safety person on site at the beginning of the installation. When they left, I could not even tell they had been there."
