EPDM Rubber Roofing Basics<\/h1>\n\n\n\n
Before jumping into a comparison between ballasted and mechanically-fastened roofing systems, it is important to have a basic understanding of commercial rubber roofing. EPDM roof membrane (ethylene propylene diene terpolymer) is the most common thermoset roof membrane in the industry. EPDM roofing mainly contains two compounds, ethylene<\/em> and propylene<\/em>, which are derived from oil and natural gas. In terms of installation, they are either fully-adhered, mechanically attached using batten bars, or ballasted. In this blog, we will be discussing the difference between mechanically-fashioned EPDM roofing and ballasted EPDM roofing.<\/p>\n\n\n\n Ballasted roofing installation involves laying loose layers of insulation sheets atop the roof decking, followed by sheets of EPDM roof membrane. Sheets that adjoin are overlapped and fastened using seam tape. Next, all accessible points and the perimeter of the roof are sealed or flashed in accordance with technical specifications. Lastly, river-washed ballast is applied to weigh the entire roofing system down for ultimate security.<\/p>\n\n\n\n Although quite similar in design and performance, mechanically-fastened roofing is installed using a different process and different materials. Starting off with layers of insulation on top of the decking, these roofs are then secured mechanically using insulation plates and fastening hardware. Next comes the layers of EPDM roof membrane sheets over the insulation sheets and plates. Like ballasted roofs, all adjoining sheets are overlapped and secure with seam tape. But rather than being flashed and sealed, they are secured in place using seam plates and fasteners.<\/p>\n\n\n\n Mechanically-fastened roofing is generally more expensive than ballasted roofing.<\/p>\n\n\n\n Ballasted roofs are most compatible with buildings that have large, open roofs and few roof penetrations. Mechanically-fastened roofs are better suited for buildings with roof penetrations or higher uplifts.<\/p>\n\n\n\n Mechanically-fastened roofs are lighter in weight.<\/p>\n\n\n\n Ballasted roofs usually have a shorter installation timeline.<\/p>\n\n\n\n Roof leaks can be easier detected on mechanically-fastened roofs.<\/p>\n\n\n\n Ballasted roofing is heavier and larger in size compared to mechanically-fasted roofs, and therefore, must be upsized to accommodate the weight of the ballast.<\/p>\n\n\n\n Are you ready to move forward with your commercial real estate design-build project in Indiana? <\/strong>Contact BAF Corporation<\/a> at 317-253-0531 to speak with an expert Indianapolis commercial general contractor<\/a> about your commercial construction<\/a> needs and options, today.
