What is single-ply roofing? 

A single-ply membrane is made up of flexible sheets of synthetic polymer that can be split into two divisions: thermoplastics and synthetic rubber. The thermoplastics option has become the most popular option for most roofing contractors on flat roof projects because it can be reheated and remoulded. Materials such as PVC are often used as a single-ply membrane material in Europe because of their adaptability to different environments and their resistance to weather. Because PVC is immune to damage from harmful materials such as acids, salts, corrosives and bases, it’s a great resistant material for use in different environments.

Single-ply roofing is also available in grades, with the higher grades offering better protection. Not only is its performance a real benefit but single-ply roofing is also one of the most cost-effective and efficient materials for getting roofing jobs done. It’s a lightweight product that makes its application even more efficient for roofers. But what do you need to install single-ply roofing? These systems are installed mainly using hot-air welding.
