From the early 2000s, Single-ply roofs have increased in popularity. These roofs utilize a one-layer roofing membrane made from strong and flexible membranes, made predominantly of synthetic polymer. The thickness of these membranes varies from 1mm to more than 2mm. Depending on the type of membrane, they can be either homogenous or reinforced with glass fibers or polyester. Single-ply membranes can be any of the following:
1. Ethylene Propylene Diene Terpolymer (EPDM)
2. Thermoplastic Polyolefin (TPO)
3. Polyvinyl Chloride (PVC)
These membranes are either mechanically fastened, heat welded, fully adhered or even ballasted (in the case of EPDM) to the rest of the roofing components. Together with the insulation, vapor barrier and other components….they provide your building with economical and durable protection from the elements.
