What is Modified Bitumen Roofing?

Modified Bitumen (MOD-BIT) Roof Systems have been installed since the mid-1970s. A Modified Bitumen roof system is typically installed with 1-3 ply and comes in a wide variety of colors. There are many ways to install a modified bitumen roof, but the four most common methods are cold-applied (liquid adhesives), torch-applied (torch with open flame), hot-applied (hot asphalt) and self-adhered (adhesives built into the sheet)

Safe & Efficient: Self-Adhered MOD-BIT Roofing

Modified Bitumen systems are typically seen as the next generation of asphaltic or pitch-based Built-up roofs (BUR). It carries many of the same strengths as a traditional BUR roof system, while the Modified Bitumen installation can be completed using a much safer and less expensive method. We typically install self-adhered MOD BIT roof systems at Chaffee Roofing due to their safe and effective installation technique. Self-adhered Modified Bitumen roof systems are similar to fully adhered single-ply roofs in that the entire system adheres to the self-adhered Modified Bitumen roof installations are completed by:

  1. Fastening the rigid polyisocyanurate insulation to the steel deck.
  2. Then, on the first ply, which is called the ply base, the backing paper is peeled off. Then, the ply base is placed over the rigid insulation and then rolled in.
  3. Now that the ply base is fully installed, each additional ply, known as the mid-ply, is installed directly over the last ply. If it is only a two-ply system, this step is skipped.
  4. Finally, the last ply, known as the cap sheet, is installed in the same manner, with the cap sheet being rolled into the mid-ply.

Benefits and Drawbacks of MOD-BIT Roofing

Some of the benefits of Modified Bitumen roof systems are:

  • Proven system that has been installed for over 40 years.
  • Proven performance of asphalt, which is known to go the distance.
  • Strongest puncture resistance of any roofing system.
  • Available in a wide variety of colors with little to no quantity restrictions.

Modified Bitumen roof systems have a few disadvantages, which are:

  • 1-ply modified bitumen roof systems have not shown any long-term success.
  • Very high cost if there are 2-3 ply that require labor and materials to install.
  • Asphaltic-based roofs rely on granules for protection from the sun. Without granules, Asphalt-based roofs crack and break apart.
  • If granules are not included with your modified roof system (known as a smooth surface mod-bit), the materials must be coated with an aluminum roof coating, or the surface will show accelerated aging. Typically, periodic recoating will be required.
  • Modified Bitumen roofs systems age prematurely if used on roofs that hold any water.
  • Some installation methods, such as torch down, are very unsafe and pose a major risk to your building.

Please note that Chaffee Roofing will not install any 1-ply Modified Bitumen roof system and will not use any open flame torch application methods. Modified Bitumen roof systems are a great option for roof systems that have heavy foot traffic or an increased likelihood of punctures. Roofing modified bitumen is also great for any roof system that requires a certain color that is unavailable in a single-ply membrane.
