Low Slope Roofing for Automotive and EV Battery Plants

Having covered millions of square feet of roofing for all the major manufacturers, JM understands the complexities of automotive and EV battery manufacturing facilities. Plants requiring a more robust roofing assembly that protects from production chemicals tend to seek a PVC membrane solution, while others lean towards TPO. In the EV/Battery space, vapor barriers offer significant value in high-humidity environments.

Why for Vapor Barrier

This video highlights what a Vapor Barrier is and its role in a roofing system. 

Colorado Mountain School Expansion Roof with JM EPDM R FIT

Summit High School (SHS) expanded its main building by 35,200 square feet. Arapahoe Roofing and Sheet Metal, Inc. won the job to roof this major addition. As a long-time Johns Manville partner, Arapahoe worked with the District’s facilities manager to choose a complete JM system that included 75 mil reinforced membrane as specified by the architect.

JM PVC with Elvaloy® KEE Covers New U.S. Bank Stadium

When discussions began about the new U.S. Bank Stadium, there was a request for an outdoor stadium. However, state and local government provided funding specifically for an indoor stadium that would be able to host major events like the professional football and college basketball championship games.
