The two common roofing membranes in single-ply membrane roofing systems, mostly employed on commercial structures, are EPDM and TPO roofs. Both can be installed on the rooftop, but there are a few minor variations to consider.
Thermoplastic Polyolefin (TPO) is a low-slope or flat roof single-ply roofing membrane. The TPO membrane is supported by a sturdy foundation often created as an insulation system despite being thin.
The membrane is available in thicknesses, most frequently in the 40-, 60-, or 80-mil range. EPDM, or Ethylene Propylene Diene terpolymer Membrane, sometimes known as rolled rubber roofing or rubber membrane roofing, is created using a mixture of slate dust, sawdust, and used car tires.
TPO roofing comes in a wide range of colors to accommodate the preferences of most RV enthusiasts. EPDM is more resilient and is a far less expensive option for RV roofs. However, it is far from the ideal option for your RV because it is less visually appealing and does not reflect UV rays. EPDM is also a superior option for your RV because it is available in lighter hues reflecting sunlight and heat.
