What is Modified Bitumen?

Modified Bitumen

Contact Our Commercial Roofing Experts in San Antonio, TX to Learn More About Modified Bitumen.

This roof type is made of a membrane derived from asphalt, along with a base mat that will be spread over the roof in rolls. Typically heated and welded together, the seams can also be stuck together using cold-applied adhesive methods. Traditional asphalt is made from the natural material, bitumen. The bitumen is blended with a mix of rubber modifiers and solvents, creating a very viscous, sticky and water resistant material.

Using rubber modifiers can help achieve the preferred physical traits after the modified bitumen has been prepared for shipping off to its final destination. There are two major types of modifiers that are commonly added during manufacturing. SBS, or Styrene-Butadiene-Styrene, improves the flexibility of the modified bitumen and can prepare it for a wider range of movement, such as expansion and contraction in fluctuating weather conditions. APP or Atactic Polypropylene can assist in improving the longevity by slowing down the aging process of the roof.

Base Mats and Benefits

This roofing option has a few varieties of base mats to choose from, such as organic felt or fiberglass. In the United States, synthetic mats are increasing in popularity. If you have an older commercial roof, it is important to have your roof check for asbestos. This was a formerly popular synthetic base mat and was officially made illegal in the 80’s due to health concerns.
