When it comes to roof repairs, choosing the right material can make all the difference in longevity, durability, and cost-efficiency. One option that continues to gain popularity across both domestic and commercial projects is GRP roofing—also known as fibreglass roofing.
But what makes GRP such a smart solution for roof repairs? Let’s break it down.
What is GRP Roofing?
GRP stands for Glass Reinforced Plastic—a composite material made from polyester resin reinforced with fine strands of glass. When applied properly, it forms a seamless, waterproof layer that is both lightweight and extremely tough.
Originally used in the marine industry, GRP has proven to be just as effective at withstanding the elements on flat roofs.
Why GRP Roofing is Ideal for Repairs
Whether you’re patching up damage or replacing an older flat roof system, GRP comes with a long list of advantages:
1. Seamless Waterproofing
One of GRP’s biggest selling points is its ability to create a completely seamless surface. With no joins or weak points, it significantly reduces the risk of leaks—making it an ideal fix for water-damaged or poorly sealed roofs.
2. Durability That Lasts
A professionally installed GRP roof can last 25+ years with minimal maintenance. It’s resistant to extreme weather, UV exposure, and temperature fluctuations, making it a long-term solution that can stand the test of time.
3. Fast and Efficient Application
Compared to more traditional materials, GRP roofing systems can be applied quickly. That makes it a great choice for urgent repairs or projects with tight timelines.
4. Lightweight but Strong
Despite its strength, GRP is very lightweight—ideal for buildings where additional load-bearing isn't possible. Its versatility means it can be used across extensions, garages, commercial units, and more.
5. Low Maintenance
Once installed, GRP roofs require very little upkeep. No moss growth, no re-felting, and no constant resealing—just a clean and clear surface that does its job quietly and efficiently.
When is GRP Right for Your Roof?
GRP is best suited for:
Flat or low-pitched roofs
Roof valleys or dormers
Balconies or walkways
Repairing leaks or worn-out felt systems
