The Siplast story of uncompromising quality and commitment to our customers begins over half a century ago with an innovation that would change the commercial roofing and waterproofing industry. In the late 1960s, Siplast Research and Development, working in conjunction with Shell Chemical of Europe, developed SBS (styrene-butadiene-styrene) modified bitumens. We found that by properly modifying asphalt with SBS, we could produce a highly durable elastomeric blend with exceptional elongation/recovery properties over a wide range of temperatures.

There are Siplast roofs applied in the early years of our SBS blend that are still in service today. Since then, Siplast Engineered Roof Systems have been applied over all types of deck constructions, in the extremely varied weather conditions of more than 40 countries. That performance history has helped us earn our reputation as a leader in the development and manufacture of the world’s most advanced roofing and waterproofing systems.
