SBS-modified bitumen roof systems
SBS roof systems brochureNo one knows SBS like Siplast. Because we invented it.
In the 1960s, Siplast drove an SBS/bitumen breakthrough in commercial roofing technology. By modifying bitumen (asphalt) with styrene-butadiene-styrene polymer (SBS), the resulting roofing products offered better elongation, recovery, and durability properties compared to other existing asphaltic roofing technologies.
As the pioneer of SBS product innovation, we continue to set the bar higher—with systems that surpass evolving industry standards and high-performance solutions trusted to protect historical structures and mission-critical facilities. The secret to the superior quality of our SBS is consistency in our manufacturing process, followed by rigorous testing and quality control to ensure each batch has met our precise specifications for optimal performance, from the lab to the roof.
For the highest quality SBS, come to the source.

Education
The smart choice for schools to maximize their roof investment, an SBS roof can provide decades of dependability and reduced lifecycle costs and reduced maintenance.
Museums
To protect the irreplaceable, a high-performance SBS roof is the premium solution for preserving valuable masterpieces and precious artifacts for facilities that can not afford leaks.
Hospitals
SBS roofs are a trusted solution for medical facilities, providing premium performance while protecting patients, staff, and visitors for the long-term.
Government institutions
Buildings that house critical operations need a robust roof to ensure minimal disruption. The durability and redundancy of an SBS roof make it a proven solution for protecting the crucial processes taking place inside.
The SBS built to outperform and outlast
Exceptional flexibility & elasticity
SBS provides excellent flexibility, allowing the membrane to expand and contract with building expansion and contraction from temperature changes, helping to prevent cracks and splits.
Long-term value
With a typical lifespan of 40-50 years and minimal maintenance needs, an SBS roof is a cost-effective investment that comes with a lower lifecycle cost.
Utmost durability
Added synthetic rubber adds protection against tears and punctures* and provides great low-temperature flexibility, ensuring durability in cold weather, while multiple waterproofing layers provide robust, long-term performance.
Versatile application
SBS membranes are compatible with various roof deck types, including concrete, wood, and metal and are offered with multiple installation methods, such as hot asphalt, cold adhesive, torch applied, self adhered, or mechanically fastened.
* Siplast warranties and guarantees do not provide coverage against hail or punctures except where additional puncture resistance coverage is purchased for eligible systems. Contact Siplast for more information. Refer to applicable warranty or guarantee for complete coverage and restrictions.
Our SBS batches are tested 150 times, because the world will test your roof every day.
Siplast premium quality SBS roof systems have certain physical properties that help enable it to maintain performance over decades of service on a roof. Combining a premium bitumen with optimized levels of polymer creates a quality standard that has remained consistent for 40 years. And our unique manufacturing process ensures consistency in tensile strength, ultimate elongation, and cyclic fatigue recovery properties, for long-term performance, exceptional weather resistance, flexibility, and longevity. Siplast conducts more than 150 quality control tests on every batch of SBS source material to ensure raw material quality. The result is a range of versatile, high-performance SBS systems that surpass industry standards.
