Single Ply / EPDM
Single ply is a flat, synthetic polymer based roofing material which provides a waterproofing layer in a single sheet. Usually supplied in rolls, the material is either entirely homogeneous or contains a reinforcement layer. Sealed at the joints with heat, adhesive or mechanical means, it can be adhered, mechanically fixed and/or ballasted into flat, pitched or green roof systems. Single ply roofs are lightweight, flexible, cost effective, swift to install and safe, which makes them increasingly popular for both new build and refurbishment projects.
