A GRP fibreglass roof is one of the most popular solutions in the UK. GRP or Glass Reinforced Polyester is a composite material that is produced when plastic is strengthened with fine glass fibres. This single ply laminate has a history spanning over 60 years as a reliable solution to cover and waterproof roofs. In recent years, the GRP fibreglass roof has increased in popularity and can be used for a variety of applications.
One of the main advantages of GRP fibreglass roofing system is that it provides a simple, safe installation. The process begins with the application of a layer of catalysed resin to completely dry, good quality roof decking. Then a fibreglass mating layer is laid over the top of it, followed by another catalysed resin layer to complete the system. Once this has cured, a top coat resin that is fire retardant is applied to weatherproof the roof completely and create a more attractive finish. The edges of the roof any abutments are fitted with trims.
When correctly installed and with sensible maintenance, a GRP flat roof can have a lifespan of over thirty years without any deterioration.
The essentials of a GRP fibreglass roof are GRP resin, fibreglass mating, top coat resin, and a catalyst or hardener. The installation will also require fibreglass flashing and roof trims, sealants, and adhesives to bond the flashings and trims. These materials are relatively inexpensive and can be supplemented with corners to enhance the roof aesthetics.
Providing the installation has been carried out properly with suitable decking and flashing, there should be little concern about repairs for your GRP fibreglass roof. GRP fibreglass is impact resistant, but if a hole or split does develop, another layer of GRP can be laid over the top of the roof, providing it is still structurally sound to ensure it remains watertight.
While GRP is unaffected by UV, you may notice that there is some fading. This will not affect anything internally, but only the aesthetic qualities of the roof. If you prefer, any colour loss can be treated with another top coat layer to restore the original glory of your roof.
If your GRP fibreglass roof does leak, this type of problem is not typically linked to the roofing material. It could be a result of a poor installation, so you’ll need to check that all trims and flashings are fitted correctly, as these are likely to be the source of the leak.
Although more costly on average, a GRP fibreglass roof can offer some advantages over other flat roof materials. It is more durable compared to traditional felt, and there are minimal seams to reduce the risk of water creep-age. The finishing top coat makes the whole roof resistant to practically all weather conditions. A GRP fibreglass roof is built to retain form and function in storms, frost, snow, excessive periods of sunshine and high winds. It is also fire resistant and has durability for footfall, making it ideal for roof terraces.

I am extremely happy with the roof repair that Adam and the team completed yesterday. They were all very professional and friendly and more than happy to show me and explain each phase of the work carried out until completion. I would highly recommend this company. I will not hesitate to use them again in the future.
Very quick to sort out our roof problem. Good value as well. And job well done.Will definitely use them in future and recommend them.
Adam was really fast to come out and see our problem. It was all solved the same day! The men left no mess behind them and I would thoroughly recommend them. We would use them again.
Adam and his team was polite on time and did a great job of putting new fascias and guttering I would use again if needed
Wow, wow and wow. After an awful experience with another company we contacted Adam and asked him for a quote. From that point the service was first class, from the scaffolding team he uses down to the final clean up. He kept us informed every step of the way and the whole team were polite and friendly. We had a full roof removed and replaced with a dry ridge system. Our roof is big and awkward to work on, but they have left us with no mess and a bright new shiny roof. We are so impressed we will be using them again in the new year for my mums roof.
Prompt efficient replacement of lead flashing & repointing chimney. Definitely recommend.
