Some questions answered

What is single ply PVC roofing?

Single Ply PVC is a single layer waterproof flat roofing membrane, manufactured from mesh reinforced polyvinyl chloride. Joints can either be glued or hot air welded, giving it superior seam strength and making it the ideal choice for large span flat roofs.

How long does a single ply membrane roof last?

While guaranteed for 20 years, the British Board of Agrement came to the conclusion that Memtec single ply PVC membrane had a life expectancy “in excess of 35 years” in most situations.

Can you walk on PVC flat roof surfaces?

Although capable of receiving occasional, light foot traffic (e.g. for maintenance and inspections), it’s smooth surface finish means it can become slippery in damp, wet and cold conditions.

What is the difference between EPDM & SIngle ply PVC?

EPDM is a single ply rubber roofing system manufactured from  ethylene propylene diene monomer (EPDM)

PVC membrane is also a single ply material, but  manufactured from mesh reinforced polyvinyl chloride. Where it really excels with it's exceptional seam strength, making it more resilient and ideal for large flat roof areas.
