Comprehensive and versatile systems for some of the harshest environments.
Johns Manville is a leader in SBS roofing systems for a reason. With over three decades of experience producing modified bitumen commercial roofing, we understand the science of formulating. This allows us to produce products that are consistent and designed for real-world applications.
As the most customizable of our low-slope commercial roofing products, we offer glass, polyester and composite reinforcements with all types of application techniques. We know you value quality, and above all, longevity in a roofing system. That’s why we continue to invest in people, technology and application engineering support to ensure that our SBS systems exhibit the proven strength, elasticity and weatherability you can trust.
