GRP Roofing

The GRP roofing system is the proven solution to almost any flat roofing problem.
 
It is formed in situ on the roof deck to create a solid, waterproofing membrane, fully bonded to the decking, that covers the entire roof without any seams joints or welds, commonly the weakest point on other roofing systems.
 
GRP is a hard wearing structual waterproofing system which cannot be cut with a knife, won't deteriorate under UV light or extreme heat and will tolerate foot traffic.
 
The system comes complete with a 20 year guarantee on the materials from the manufacturer.  
 
The system can be used on any size of roof regardless of complexity and is available with a choice of finishes and in a range of colours.

What is GRP

GRP (glass reinforced plastic) is the technical name for what is commonly known as ‘fibreglass’. Originally developed in 1938 for use in insulation, GRP is extremely durable and today is used in a variety of applications across a number of industries.

GRP is extremely versatile, strong and waterproof, making GRP the ideal solution for applications such as roofing systems. Fibreglass, is made up of chopped strand mat made from glass fibres which are laid in situe and then held together with layers of polyester plastic (resin) which becomes hard after being cured. Once cured it becomes a very tough material which can be formed to any size, shape, colour or thickness. A key benefit is that it is light weight making it ideal for roofs but extremely secure so it does not compromise on security.

The GRP roofing process ensures that your roof is completely sealed with no joints meaning that even the smallest drop of water can’t seep through.  Once installed you won’t have to do any maintenance to the roof, leaving you with total piece of mind. A GRP flat roof meets British Standards to BS476 part 3 FAB and comes with a comprehensive guarantee. GRP Roofing can resist heavy traffic and can be sealed with a non slip coating, therefore suitable for balconies and walkways.

How long will it last?
Many glassfibre laminates made during the early days of GRP production in the 1940s are still in use today. Extensive testing has demonstrated the typical life expectancy of a GRP roof product to be well in excess of 50 years. And, tests conducted to date have shown ‘no deterioration’ infrastructure or performance throughout the testing period. Additionally, because GRP products or use in extreme conditions such as underwater, when used in the manufacture of boats, a GRP product applied by a specialist company could be expected to last a lifetime.

 

What are the main benefits of GRP roofing?
GRP has a number of benefits compared to traditional roofing products, especially for flat roofing.   GRP flat roofs are extremely durable and completely waterproof. The entire area on a GRP roof is encapsulated into one single continuous GRP membrane and there are no seams joints or welds. It is also completely UV resistant. GRP roofing systems are also highly adaptable allowing conversion of the roof area to include features such as balconies or walkways within the roof area.  GRP roofing systems can also be used instead of pitched roofs or to make special features. The major benefit of GRP roofing comes from the fact that a high-quality GRP roofing system  should remain leak-free for life.

Is a GRP roof fire retardant?
The specially formulated roofing resins and topcoats with fire certification with no restrictions on their use which is your guarantee for situations where fire safety is a necessity.

What are the main applications of GRP?
GRP can be used for a number of applications including roofing, automotive, construction, marine and industrial, including, boats, car bodies, HGV roofs, and shells, pipes, hygienic linings, tanks, building products, ponds, pools, architectural features, green roofs, flat roofs (commercial and domestic), vertical cladding, walkways, bay windows, wind turbine blades, plus a number of other specialist areas.
