GRP Roofing
GRP Roofing in Swindon
GRP (Fibreglass) roofing System
A survey of GRP buildings by the BRE (Building Research Establishment) in 2001* found the condition of several GRP Buildings around 25 to 30 years old to be structurally sound. An except of this report is found below.
GRP Modular Stores Building
A Modular GRP stores building was constructed at Wollaston in 1968, to demonstrate the suitability of this material for construction purposes. When examined 28 years later it was found to be mechanically sound.
The BRE noted that today's materials would undoubtedly have a much improved service life.
Cost Effective
When GRP is considered for large scale projects in comparison to traditional bituminous roofing materials, it may not compete on cost but it's lifespan will always be many times greater. GRP is frequently specified by local authorities for large scale jobs as a cost-effective and permanent solution.
Over the last 12 months we have managed to obtain a better deal with our suppliers due to the amount of GRP materials that are purchased, we can now offer a replacement roof in GRP at just 10% above any other flat roof material used, this is based on a genuine quote supplied to us.
In Comparison between traditional flat roofing systems and GRP there is only one clear choice.
Traditional bitumen based roofing systems rely on building up several layers of materials to waterproof the roof, each layer usually represents five 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 out last the structure it is protecting.
One of the features of GRP which sets it apart from nearly any other roofing system is that it is Monolithic Laminate. This means that it does not suffer the problems problems inherent in systems that have seams, joints or welder, which are usually the weakest point of any roof.
Because the GRP is constructed from 1 layer , it is less labour intensive and quicker to install than many other roofing systems, obstacles or features can either be weatherproofed or incorporated into the substrate with ease on any size of roof and in any colour, GRP roofing is also cold applied which avoids the prohibitive cost of insurance associated with hot woks.
