GRP stands for Glass Reinforced Plastic. GRP fibreglass has become a popular roofing material over the past decade. It was originally unpopular, as flawed installation practices led to poor quality roofs. Now skilled roofers can install a fibreglass roof that can last for more than 25 years.
But is GRP fibreglass the right flat roofing material for you? We’ve put together a pros and cons list to help you decide.
Fibreglass roofing is durable. It isn’t affected by the weather and is a great choice of material if you want a roof that you can walk on without damaging it. Fibreglass roofing is also strong and very unlikely to leak.
Fibreglass roofing will last for a long time. If the material is good quality and installed correctly, it can last for more than 25 years.
Fibreglass roofing is lightweight. This means that it’s suitable for weaker buildings, as well as those with a stronger roof structure.
Fibreglass roofing repairs well. You can either patch or resurface it, and all repairs are almost invisible.
Fibreglass roofing is versatile. It’s suitable for roofs of different sizes and shapes. It also comes in lots of different colours to suit your property.
Fibreglass roofing is expensive. It costs more than other flat roofing materials, like felt, asphalt, rubber and PVC. Prices vary depending on thickness, finish and quality, but compromising in these areas may mean that your roof won’t last as long as it could.
Fibreglass roofing is relatively inflexible. This means that it’s not suitable for roofs that are flimsy or prone to movement.
Can only be installed in dry weather
Fibreglass roof installation is only possible in totally dry weather. This means that you may need to wait a while to get your flat roof laid.
