EPDM
Ethylene propylene diene monomer (EPDMi) has been among the most popular materials for both new and re-roof low slope applications. It has been an appealing choice for the commercial roofing industry since the 1980’s. EPDM manufacturers have continually improved the quality and performance of the product. EPDM exhibits superior flexibility and high strength, which is ideal for shifting roofs and unusual shapes. Basically, it is a high-performance synthetic rubber compound that is ideal for the Midwest climate and also great for all weather characteristics worldwide. It is a versatile membrane that offers a variety of installation options.
Fully adhered, ballasted, or mechanically attached are the most common installation methods. Bruttell Roofing believes a 60 mil fully adhered application will deliver superior long-term weatherability and exhibit exceptional wind uplift resistance. Fully adhered EPDM is a lightweight application that bonds the material to the insulation. Ballasted EPDM provides fast coverage at a lower cost. The material is laid loosely over the insulation and held in place by smooth, river-washed stones. Twelve pounds per square feet of rock are required to hold it in place. It is traditionally the easiest of all systems to install but also the heaviest. The seldom used mechanically-attached EPDM application is fastened to the deck using round plates and screws.
