Specialty Roofing Products

As a total roofing systems provider, Johns Manville complements our membrane and insulation offerings with a full line of specialty roofing products. This provides single-source convenience to our contractors and specifiers. It also allows building owners to enjoy the convenience of an edge-to-edge total roofing system guarantee.

Our Expand-O-Flash® line has been designed to withstand certain levels of  seismic forces, movement between building components (such as atriums and window walls) or movement caused by extreme temperatures (particularly around pipes, ducts and bulk-carrying equipment).

JM’s Specialty Roofing Products group has established its expert reputation by offering custom  fabricated components. We’ll turn your rough sketches into a custom-manufactured solution. And best of all, it can be included in your Johns Manville Peak Advantage® Guarantee. To learn more, contact the Specialty Roofing Products group at (800) 445-1500.
