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.
