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.

Warren did a super job for me, sorting out my broken tile and gutters quickly and without fuss. Wouldn't hesitate to use again, thank you.
Warren responded very quickly, was able to come the same day to take a look at and eventually repair a leaky roof. Very knowledgable and professional. And the leak is fixed!
Paul Williams got in touch when he said he would, gave the quote and did the job within reasonable time, somewhat set back by the weather. He was very easy to deal with and responded immediately to my emails. Full marks for that! I will use him again if I have a problem.
Thoroughly recommend Paul. Contacted Paul after another roofer left us with a leaking flat roof and was unable to resolve the issue. Paul replaced the flat roof and no more leak. Would definitely use him again
Could not have asked for a more. They were professional and efficient. Would highly recommend.
After posting the advert for a garage roof that needed a complete overhaul David was able to visit straight away. He was very knowledgeable and talked me through all of the details. Their quote was the most competitive and communication was excellent! The roof was completed to a very high standard and I am very impressed with the company. Would definitely recommend them to friends and family!
Fantastic job! I wouldn't hesitate to hire David and his team again.
5 tiles replaced and gutter work including facias and gutter cleaning. Michael from MK maintenance carried out some work on my mum’s house done a great job and would highly recommend very clean and tidy and we would definitely use for further work and to recommend to family and friends thanks.
Mike did a great job cleaned up well after and disposed of all the rubbish. Will use again and would recommend him to anyone.
We had worked carried out last year that was excellent by Micheal. He was very polite, tidy and reliable. Had a small problem and he came straight out and corrected it. Would definitely recommend.
Michael was quick to investigate and identify the source of my leak and resolved the issue promptly for a very fair price. He was really easy to talk to and I'd highly recommend him to others looking to get roofing work completed!
RFR made the time to come out and inspect the bay roof which had leaked in the previous night following a heavy storm. He explained that it needed a repair not a replacement and set to work straight away. They explained very clearly what needed doing and the the cost involved, which was very reasonable. We were very relieved to say the least, having assumed the roof might need a very costly replacement. We would have been none the wiser had someone confirmed our worse fears. RFR were very honest and helpful and even troubled to advise us on how to make good the damage to the inside decoration. We would not hesitate to use RFR again and can recommend him without reservation.
Saved me from a real emergency. Great care from start to finish. Would highly recommend.
Paul and his team did a first class job after we had been let down by other people. Someone who turns up and does what he says he’ll do. I have no hesitation in recommending this company for any roof repairs.
Michael is very knowledgeable and his advice was invaluable in deciding the best option to repair my ridge tiles on my roof. His quote was very competitive and the standard of his work was very high, moreover he ensured that any mess was tidied up and taken away for disposal. I have not hesitation in recomending MK Maintenance.
Good service kept us informed from start to finish roofers on time and polite
Warren was so professional and helpful. Warren put right our guttering that was done so poorly by a different company. We are extremely happy with the service and wouldn't hesitate to employ him again for future roofing work. Thank you.

Paul Williams responded immediately and visited to survey the job and explained what was required - very friendly chap. A week later I received a quote. My inclination is to take up Paul’s quote but I am ‘still’ waiting for other quotes from other companies before committing myself.
Called on Monday afternoon, Toby came out the next morning and my roof leak was sorted in the afternoon by Mark and Shaun, Thankyou guys for such great service and the price was good too.
