At Bone Dry Roofing Company, in addition to excellence of craft and customer relationships, we are also known for offering commercial roofing systems from three of the world’s top manufacturers: Carlisle SynTec, Johns Manville and Firestone. As we continue our series highlighting what these manufacturers and roofing systems provide, the focus of today’s post is on Johns Manville EPDM membrane roofing (previous posts covered Carlisle SynTec). Other roofing membranes from Johns Manville that we’ll be walking readers through on the blog are their TPO, PVC, SBS, APP, BUR and Liquid Applied solutions. We will then move onto commercial roofing offerings from Firestone. Let’s take a look at the history of Johns Manville before concentrating on their EPDM membrane roofing.
Company History
Having recently celebrated their 160 year anniversary, Johns Manville (JM) began in 1858 in New York City by Henry Ward Johns. From the basement of his tenement building, with “his wife’s new clothes wringer and a household tea kettle, he applied hot tar to cloth and created the company’s first roofing shingles.” With a laser focus on innovation and desire to challenge the status quo, the company has survived challenging times (their website mentions the American Civil War, two world wars, The Great Depression and more). Today, their goal is to develop new energy-efficient products, those that boost indoor air quality, lower energy costs and provide comfort. Their core values are “People, Passion, Perform and Protect,” which you’ll see in their actions as a company and the products they design.
EPDM Basics and Benefits
We walked readers through the basics of EPDM membrane roofing in our first post in this series. If you are new to EPDM, it’s incredibly versatile on low-slope projects and translates into superior waterproofing protection. The EPDM Roofing Association reports: “EPDM (ethylene propylene diene terpolymer) rubber roofing membrane has been an appealing choice of the low-slope commercial roofing industry for over 40 years.” A few EPDM benefits highlighted on the Johns Manville website include:
- Superior durability and flexibility
- A technologically advanced production process that allows Johns Manville to “extrude” their sheets “instead of using the traditional calendering process”
- A thicker EPDM product “with a more uniform surface finish”
- Cleaner sheets mean “less preparation to ensure a stronger bond during installation”
Installation and Options
With any roofing system, installation is critical. At Bone Dry, we offer a full-service commercial roofing department able to handle an array of roofing projects (any size and complexity). After the initial contact, we move through our design solution phase, into production, and through our structured close out procedures.
