Single Ply Roofing Systems for Flat Roofs

Flat roofing systems have evolved significantly in recent years, and among the most popular, cost-effective, and high-performance solutions today is the single ply roofing system. At FRC Roofing, we’ve installed countless single ply systems across Bristol, Bath, and the Southwest, offering long-lasting waterproofing for both domestic and commercial properties.

In this guide, we’ll explore what single ply roofing is, its key advantages, and why it might be the right choice for your next roofing project.

What is Single Ply Roofing?

Single ply roofing refers to a flexible, synthetic membrane used in flat or low-slope roof construction. It’s laid in a single layer (hence the name) and typically made from durable materials such as PVC (Polyvinyl Chloride).

These membranes are either mechanically fastened, fully adhered, or ballasted depending on the project’s needs.

Common Single Ply Manufacturers

  • Sika-Trocal
  • Bauder
  • Danosa

FRC Roofing is proud to be manufacturer-approved for several of these systems.
