Fibreglass GRP Roofing Cornwall
Fibreglass (GRP) is a robust material which we all know is used to keep water from getting in to boats, ponds and pools. It is just as good, however, at keeping water out and therefore is perfect for creating strong, durable and long-lasting waterproof flat roofs.
Cornwall Flat Roofing, based in Truro, installs fibreglass flat roofs throughout the County of Cornwall, using the top quality Crystic ROOF system, designed and produced by Scott Bader Ltd – the UK company with more than 60 years’ experience in polyester chemistry. This system comes with a 10-year material guarantee, and Cornwall Flat Roofing usually adds on their own 20 or 25-year warranty, being confident in both the excellence of the product and their workmanship.
The Cornwall Flat Roofing installers have undergone full training in the application of this long-lasting alternative to traditional roofing materials, so customers can be assured of a professional finish and a high standard of workmanship.
GRP stands for Glass Reinforced Plastic – a material made from a polyester resin, reinforced by chopped strands of glass fibres, which we know as fibreglass.
This versatile material is lightweight yet robust, so it lends itself to many applications, being particularly effective as a solution for flat roofs.
The fibreglass roofing needs to be laid onto dry, clean Sterling OSB3 tongue and groove decking boards, fixed to the roof structure. If you opt to have a fibreglass roof the Cornwall Flat Roofing team will expertly lay the decking for you, or if you wish you can do this yourself.
Application of the fibreglass resin laminate needs to be done in dry weather, with the temperature at 5°C or above, so the work has to wait for a fine, dry day. Once started, the work proceeds quickly, so even a fairly large roof can be fibre-glassed, laminated and top-coated in one day. The warmer the weather the quicker the resin laminate will cure. The experienced roofers from Cornwall Flat Roofing are adept at judging just the right lengths of fibreglass matting to lay and how much resin needs to be mixed, so wastage is minimal should weather conditions change. It’s all part of the skill required to ensure that the fibreglass matting is well-covered with no trapped air pockets, ensuring that the laminate is well consolidated.
The top coating sealant needs to be applied evenly as soon as possible once the laminate is cured. Complete curing takes a few days, but the roof will be sound while this process takes place, even up to having any decorative finishes applied with no ill effects.
Fibreglass GRP roofing can be supplied in a variety of colours, and is often used to simulate lead or copper roofs. The smooth, seamless, watertight finish allows for it the roof to be turned into a “green” roof, roof garden or roof terrace, and it is a smart and stylish solution for roofing dormer windows, bay windows or balconies. This roofing system is suitable for any flat roof, from a simple shed or garage to a new build, or a heritage building.
