It may not be a new product on the market for general use, but fibreglass is a new one in the world of roofing. It’s always been used over the years for roofs but it’s not always been a popular option because it has been such a challenge to install. Not only that, but people have used boat fibreglass and the wrong expertise for installing the GRP roofing. Luckily, we now live in a time where the challenges are being addressed and the fibreglass used for a GRP roof is specialised for roofing. The trims that are made for the same roof are factory made and are made specifically for flat roofs.

Installation of a GRP roof is now better than ever, with those installing them having better installation skills, and it’s because of all of this put together that GRP roofing is now right at the top of the list for best roofing. However, like everything else, there are pros and cons to consider. Understanding what these are can help you to make the right decision for your roofing needs, and move forward with clarity of which material is the right one for you.


  • They’re durable. Firstly, if you are going to be installing a new roof, you want one that’s going to last for your home. The problem with choosing something else is that you won’t get the same durability and you’re likely to be forced to continue to replace it. GRP roofs are those that you can count on, with a durability of over 25 years.
  • They’re flexible. You don’t have to use a GRP roof on just your house, as it is well known for its flexibility properties. Whether you are looking for lightweight roofs, green roofs or complicated roof shapes to be installed, a GRP roof could be the best option.
  • They’re easy to repair. Your roof is always going to be known to need frequent repairs and you need to check on it frequently to know whether it needs any changes. When you repair fibreglass, you get an easy fix and some of those repairs can be done on your own without the need to call in help.


  • They cost more. When you compare it to rubber materials, GRP costs more. However, there’s a reason for it! The advantages above can spell that out for you.
  • They’re not for large roofs. It’s not always the best option for larger roof areas, and the expansion rates can be high.
  • They’re picky. You can’t just install a GRP roof; you need to wait for the weather conditions to fit the installation – as in, when it’s dry out!
