Single-ply roofing is a popular option as it is highly-reflective, durable, and low-maintenance. It can also be installed in a single layer using adhesives or fasteners. You can find single-ply roofing in a number of materials, such as TPO and PVC. Single-ply membranes may also contain reinforcement layers, such as glass fiber, polyester fabrics or scrims, or fleece or felt backing. Over the last several decades, single-ply roofing has replaced many older materials used on commercial roofs, such as tar paper. When properly installed by professionals, single-ply roofing systems offer countless advantages over traditional materials due to their unmatched flexibility and strength.
