Roofing Systems - Defy the Elements

Johns Manville Roofing Systems are dedicated to helping you defy the elements with the most extensive offering of low slope roofing solutions. To construct highly protective, energy efficient and cost effective roofs, an integrated JM system delivers more value than individually purchased components. Tested and proven to work together, the elements of a JM roofing system are designed to meet the specific requirements of each individual building.

Part of our system approach is the inclusion of technical and customer support as well as strong guarantees which add peace of mind to the value equation. Single-source supply also means single-source responsibility and single-source dependability. For long-term performance look to JM for advanced capabilities in the building sciences.

Innovative Products

JM's emphasis on research and development helps us anticipate market needs and meet evolving building requirements with creative solutions.

The science behind our materials and products is extensive. Working in partnership with our customers, JM's new product development teams are challenged to adapt new and innovative technologies that cost-effectively increase the performance of commercial/industrial roofing systems.

The Johns Manville Technical Center in Littleton, Colorado is one of the best-equipped research facilities in the country, with extensive capabilities in structural, chemical, mechanical and thermal analyses. Here, JM scientists and engineers test and develop products to find technology-based solutions for specific market and product needs.

Examples of JM innovations include:
  • Multiple Cool Roof Systems — to include TPO and PVC single ply roofing systems; and SBS CR and BUR Glaskap® CR reflective, white mineral surfaced cap sheets
