What Are Flat Roofs Made From?  30th September 2020

Flat roofs have proved to be incredibly popular in commercial and residential settings, but there are so many systems available, such as Felt. Asphalt, Fibreglass, EPDM rubber, single ply and Kemper overlay systems to name a few.

All of these systems can serve you well, giving you excellent protection for many years. That said, there are different materials and techniques involved in each solution, so it’s vital to gain an understanding of the features, before deciding which one is best for your property. Out of the many types we’ve touched on above, the two that stand out are GRP flat roof and single-ply membrane.


The two main types in the UK today

GRP / Fibreglass

As many flat roofing professionals will tell you, GRP / fibreglass roofing is incredibly strong, made from fibre reinforced plastic, using glass fibre. The fibres can be flattened into a sheet or woven into a fabric, but the strength comes from fibreglass and catalysed resin, which forms a strong and durable composite. You will find this system on many domestic and commercial properties, such as:

  • Sheds
  • Garages
  • Extensions
  • Balconies
  • Schools
  • Hospitals
  • Factories
  • Industrial units
  • Offices

It is, therefore, a very versatile solution with a long lifespan. To give you an idea, we can provide a 30-year guarantee with our fibreglass flat roof installations, so if you choose GRP / fibreglass, you can be confident it will stand the test of time.


Key benefits of GRP flat roofing at a glance

  • Does not require use of complicated machines. In fact, installers don't even use heating tools. Thus, it results in safer installations with low risks of accidents.
  • Fibreglass roofing comes with a life expectancy of at least 20 years.
  • You have the freedom to choose from a wide range of trims that suit your home’s exterior. It ensures a waterproof topcoat finish.
  • Minimal maintenance - you only need to wash the roof with water to keep it clean.


Single Ply

This type of roofing system consists of rubber sheets and other chemically adhered synthetic materials that protect the roof from extreme weather conditions. Single ply roofs are lightweight and easy-to-install, with sheets that are easily joined together using a heat gun to form a watertight seal. They do not require any naked flames or hot melt adhesives on site, which minimises health and safety risks. Furthermore, there is a wide selection of colours and finishes to choose from.
