Johns Manville

In 1858, 21-year-old Henry Ward Johns used his wife’s clothes wringer and a tea kettle to apply hot tar to cloth in his New York City basement. By doing so, he created the company’s first roofing shingles. More than a century and a half later, we continue to constantly challenge ourselves with a focus on innovation and a refusal to be satisfied with the status quo.  In 2001, Johns Manville became a wholly owned subsidiary of Berkshire Hathaway Inc., which gave us a strong financial foundation and renewed our commitment to providing innovative solutions for our customers’ needs.

Here at Johns Manville, we build on decades of experience to manufacture commercial roofing, premium-quality insulation and a variety of engineered products for our customers. We are proud to be part of Berkshire Hathaway, one of the most respected companies in the world. Our values of People, Passion, Perform and Protect drive the way we work as we strive to deliver positive and powerful JM Experiences to our employees and to our customers. Our company is based in Denver, Colo., where you will also find our global research and development facilities.
