Fibre Glass, or GRP (Glass Reinforced Polyester) as it is better known in the trade, is an ideal roofing material. A GRP roof is a single-ply GRP laminate applied in situ over a good
quality conditioned plywood or SB3 deck. The roof is finished with pre-formed GRP edge trims and a coat of pigmented topcoat.
GRP has been used as a waterproof material for over 50 years for applications as diverse as boats, water tanks, lorry and car bodies, roof lights, ponds and pools. When used to construct a boat, GRP will provide waterproofing protection for the boat’s entire lifespan of 20 plus years without the need for maintenance or replacement. This same level of performance is easily replicated on a domestic roof.
A survey of GRP buildings by the BRE (Building Research Establishment) in 2001 found the condition of GRP buildings around 25 to 30 years old to be structurally sound.
Cost Effective
Compared to felt and bitumen products, Fibre Glass is more expensive but this cost is offset by increased life expectancy.
GRP is frequently specified by local authorities for large scale jobs as a cost-effective and permanent solution.
Strength
A GRP roof is perfectly safe to walk on and unlike felt or bitumen products, is less likely to be damaged. GRP is completely impervious to moisture and can outlast other roofing materials by decades.
Many of the first GRP roofs laid more than 35 years ago are still in service today.
Why Break with Tradition ?
Traditional bitumen based roofing systems rely on building up several layers of materials to waterproof the roof. Each layer usually represents 5 years of waterproofing and as the layers break down and become ineffective the roof will eventually leak.
A GRP roof will outperform virtually any other traditional or modern roofing material and has the potential to outlast the structure it is protecting !
