The Duro-Last Rock-Ply roofing system is ideal for applications where appearance is important but traditional rock or stone ballast may not be practical. The Rock-Ply membrane provides a ballast look and the watertight performance of a thermoplastic, single-ply roofing system. The Rock-Ply system is prefabricated to fit the dimensions of the roof space. Deck sections are mechanically attached or adhered to the roof deck and adjacent edges are heat-welded together, forming a watertight, monolithic covering.
