GRP or Fibreglass flat roofing
Useful for a variety of applications fibreglass is durable, waterproof and extremely long lasting. There’s the option to create a variety of finishes in a range of colours making it one of the most versatile of the flat roofing materials. This type of roof is encased in a single GRP sheet meaning there are no unnecessary joints or seams, it’s also suitable for footfall, so great for balconies and terraces.
Fiberglass roofs come with a minimum guarantee of 20 years and a properly installed GRP flat roof will remain leak free for its entire life time. As well as being durable, waterproof, cost effective and lightweight it is also cold-applied, meaning heat isn’t required for sealing seams making it safer to install.
For all of the good points about GRP you’d expect it to be balanced somewhat by the disadvantages. There are, however, relatively few. It’s quite an expensive option but still worth the cost considering its life span, durability and low level of maintenance required to keep it at its best. One other small drawback is that it requires completely dry weather to install, so the time of the year needs to be taken into consideration when you’re choosing your roofing material.
The production of GRP is relatively environmentally friendly making it an eco-friendly option. It also has a very long lifespan, some of over 50 years which adds to its environmental benefits.
