Is single ply right for my flat roof?

Single ply rubber roofs have been installed on a variety of flat roofs for decades. As a low cost, quick to install system, they’re perfect for retail outlets, factories, apartment buildings and domestic properties. A word of caution though: if you’re expecting foot traffic or equipment placement on your flat roof (think window cleaners, gutter cleaners, maintenance workers, etc), we recommend that you choose a more durable option, since single ply can tear.
