Single-ply roof membranes are one of the most popular flat roofing materials, ideal for lightweight, cost-effective fast-track construction projects. They work well for a variety of projects with roofs of all shapes and sizes, including exposed roofs, green roofs, cool roofs, ballasted roofs and more, from large scale commercial projects such as airports and factories to a private house rooftop.
