Single-ply roofing systems are composed of insulation, a single-ply membrane, flashing, and roofing adhesive. TPO, EPDM, and PVC are the three most popular types of single-ply membrane systems. Since these systems consist only of a single layer of roofing over insulation, they are low in weight, making them an ideal choice for new or retro-roofs.
