Why Use Asbestos in Roofing Materials?

Asbestos is:

  • Lightweight
  • Chemically Non-Reactive
  • Resistant to Heat
  • Inexpensive
  • Tensile Strength greater than Steel

Due to the exposure and protection that roofing provides for the structure it gets punished by sunlight, frost and moisture. Asbestos was used to prolong the life of roofing products. Due to its high resistance to degradation, Asbestos fibers hold and bind other materials together. Asbestos has a higher tensile strength than steel making it ideal for helping strengthen roofing materials. Asbestos has extremely high fire and heat resistance. This makes it a perfect material to use for additional fire protection on a roof. The weight of Asbestos is very light in comparison to Asphalt, Tar and steel. Using Asbestos in roofing materials reduces the weight load on a roof making the construction much easier. Asbestos is an inexpensive material that was added in bulk to various materials by building product manufactures.
