GRP stands for ‘Glass Reinforced Plastic’. It is a material made from a polyester resin. This resin is reinforced by chopped strand mat glass fibres to create a GRP laminate.
Glass fibres have been produced for centuries. But mass production of glass strands was accidentally discovered in 1932 by Games Slater. When he directed a jet of compressed at a stream of molten glass and produced fibres.
Unlike the glass fibres used in insulation. For the final structure to be extremely strong. The surface of the fiber’s must be nearly 100% free of any defects. This means the fibres can reach gigapascal tensile strengths.
The reason for the popularity of GRP in roofing is due to both the extreme strength of the material and its ease of handling. It’s relatively easy to handle due to being surprisingly light.
A fibreglass flat roof is one of the most popular flat roofing solutions in the UK.
The installation of GRP roofing system is safe, simple and effective. The finished product is both aesthetically pleasing and long lasting. Coming with long guarantees.

The cost of any GRP roofing system will depend upon whether an existing roof is being repaired or if a new roof is being constructed.
Obviously, a new roof will cost more than an existing one being repaired.
The area of your roof, the amount of tradesman needed to conduct the work, the amount of alterations required and the need for any structural repairs all play a factor in the cost of a GRP roofing project
Given the superior performance of GRP roofing in comparison to other systems such as felt. The price for GRP fibreglass roofing is higher. However, when you consider the life span of a GRP roof alongside a felt roof you will see the cost per year of a GRP roof is very favourably priced in comparison to a felt roof

The reason for this is fiberglass roofing benefits from some advantages that most other roofing systems cannot compete with.
It is both a lot more durable than traditional felt systems and significantly safer. It is safer because with GRP there is no need for any open flame tools.
Fiberglass flat roofs also benefit from there being no need to have joints on the main part of the roof. This gives a more attractive appearance and decreases the probability of any water penetration the surface and reaching the decking. GRP has fantastic waterproofing properties, best illustrated by its frequent use in the manufacture of boats and yachts.
The top coat finish of GRP roofing makes it resistant to all types of weather. Fiberglass roofs will retain their form and function in the face of the intense sunshine, severe snow, heavy rain and even fire.
The durability and strength or GRP mean it can cope with footfall making it an ideal surface for a roof terrace.
GRP flat roofs are very easy to maintain in comparison to other roofing systems. All you need to keep a fiberglass roof in top condition is to give it a brush and a hose down every few months. And it will continue to protect your property effectively.
