SBS Roofing stands for Styrene Butadiene Styrene, which is a type of Modified Bitumen Asphalt, popular among commercial roofing in the United States.
SBS Modified Bitumen is also a useful roofing material for commercial and industrial settings. Being set in hot asphalt allows the material to have a strong bond and last longer. These roofs can be built up in multiple layers for extra strength. We have installed SBS Roofing on hundreds of roofs across the USA so if you want to learn if it is right for your roof, contact us today!
The Roofed Right project manager, Bobbie, did an outstanding job. Our flat roof replacement was very well coordinated and scheduled and was completed in the expected time. Bobbie checked with those of us who work in the building regarding concerns. She was knowledgeable and handled all issues promptly. The crew was polite. I would definitely recommend Roofed Right America for a trouble-free project.

Modified Bitumen (MB), an asphalt material, is manufactured with modifiers that give it plastic or rubber-like properties. The commonly used bitumen roofs are SBS and APP(Atactic Polypropylene).
SBS is one type of Modified Bitumen roof system. A wide range of reinforcements can be used in SBS roofing materials, including fiberglass and polyester. The substrate often determines the type of system being installed. Fiberglass mats and polyester reinforcements are the typical bases for these products. Fiberglass weighs less at about 1.0 to 2.5 pounds per 100 sq. ft. and Polyester weighs in at 3.5 to 5.0 pounds per square feet. The weight can influence work efficiency and strength over time, so we can help you choose what is best for your project.
Modified roofs have proven performance on residential, commercial, and industrial applications. Roof help recommends all modified roofs be installed on slopes not less than 1/4" per horizontal foot (stated "quarter in twelve" or "quarter-inch slope") in order to achieve positive drainage.
While APP was being looked into in southern Europe, northern Europe was experimenting with a different type of modifier called Styrene Butadiene Styrene (SBS). The French and Germans found that if they added 10%-15% of SBS rubber to asphalt, the asphalt’s characteristics changed to those of the rubber additive. They learned that they could stretch the SBS modified asphalt up to six times its original length and that, unlike the APP, it would return to its original size when allowed to relax.
