GRP Fibreglass Roof
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.
The Installation
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 Necessary GRP Roofing Supplies
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.
GRP Fibreglass Roof Repair
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.
GRP Fibreglass Vs. Other Flat Roof Materials
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. If you’re still unsure whether a GRP fibreglass roof is the right choice for your project, you should speak to us.

I called Louis when I was horrified to discover I was missing a tile on my roof and I had 1 sq ft hole in my roof. He came by the same day, within a couple of hours, climbed onto the roof and replaced the tile within 5 minutes! He then declined payment in favour of a good review here. So, once again, many thanks Louis - you're a lifesaver!!

Louis provided a fantastic service, he was able to visit us the day after I asked for his help, and called beforehand to say he was on his way. A section of the wire mesh protecting our solar panels had come loose. Louis carefully repaired it so that we don't have to worry about those pesky squirrels and pigeons making a nest. Excellent job, so friendly and courteous. Thank you Louis. Would 100% recommend.

Louis came out promptly to quote. He was very knowledgeable, and suggested with the age of the roof it would be better to replace rather than repair. I am glad we did as the roof did not have any boarding and there had been signs of water damage where the roof joined the garage. He arranged a team to clear the Debris before he started to lay the new roof, so the area was kept clean and clear. Louis and his team were very polite and nothing was too much trouble. Would highly recommend them.

Can't fault the professional and personal approach from C.R.S Roofing. When you're putting your trust in someone coming to your home and carrying out works than can be expensive and time-consuming, it's crucial you have someone who communicates well, often and appropriately; doesn't feed you excuses but is upfront and honest; arrives when they say they're going to arrive; and do what they say they're going to do, at the agreed price and time, and to a high standard. C.R.S Roofing did all of this. We required a chimney and old skylight to be taken away, with a velux window and new skylight fitted. This was done quickly, with minimal disruption or mess, and we are very happy with the results. Any delays or issues were quickly raised, discussed and mitigated. Highly recommended.
