With an array of roofing options available for commercial buildings, identifying the right one can feel like a minefield. Significant investments and potential for downtime puts the pressure on, requiring you to find the most long-lasting and effective solution. At Industrial Roofing Services (NE) Ltd, we’ve been supporting business owners for years in doing just this. In today’s blog, we’ll be discussing a versatile material that continues to win the vote for commercial properties – PVC Membrane Roofing.

What is a PVC Roofing Membrane?

PVC or polyvinyl chloride membrane roofing is a single-ply material that is primarily used on flat roofs. It has been a popular option for commercial buildings for over 50 years and continues to be chosen above all other options. To create a hardwearing and durable roof, PVC is normally placed on either side of polyester to heighten support and help to improve the flexibility of the roof during bad weather conditions.


  • Strong – One of the main benefits of PVC membrane roofing is its strength. It has been specifically engineered for this purpose and designed to last upwards of two decades. This also allows it to have a minimum breaking strength of 200lbs/inch, however, this has been known to be higher.
  • Weather Resistant – PVC roofing is welded using hot air. This gives it an impermeable bond and one that is watertight. In addition, these seams mean that it can withstand the pressure from ponding, reducing the risk of damage with bad drainage. The flexibility of PVC allows it to move in strong weather conditions and reduces the risk of cracks. There is evidence to suggest that some PVC roofs have been able to withstand hurricanes.
  • Chemical Resistant – PVC has good resistance to a range of chemicals. This makes it ideal for commercial buildings that exhaust fumes out of their roof. It can also withstand extended exposure to animal fat.
  • Fire Resistant – PVC roofs have been known to self-extinguish themselves once a fire has been put out. They are difficult to dignity and are slow-burning, improving their safety for busy commercial settings.
  • Mould Resistant – The durable nature of PVC welded roofs makes them resistant to mould, bacteria and plant roots alike.
  • Friendly to the environment – PVC is highly efficient at cooling and heating. It has a highly reflective surface which reduces wasted energy and helps to mitigate heat build-up in cities.


  • Costly installation – In order for a PVC roof to be laid, it requires a clean and flat surface. In some situations, the old roof has to be entirely removed. This incurs additional labour costs and requires specialist installation for the best results.
  • Can be difficult to repair – Older PVC roofs were constructed differently from the ones we have now which makes them difficult to repair.
  • Not suitable for foot traffic in low conditions – Extreme cold can increase the risk of PVC shattering and experiencing puncture damage. This also makes it unsuitable for high foot traffic, specifically if you live in a region where the temperature regularly plummets.
