What is a GRP Roof ?

A GRP roof is a single-ply GRP laminate applied in situ
over a good quality conditioned plywood or OSB 3 deck.

The roof is finished with pre-formed GRP edge trims and a coat of pigmented topcoat finish

COST EFFECTIVE

When GRP is considered for large scale projects in comparison to traditional bituminous roofing materials, It doesn't 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.

CAN BE USED FOR ANY APPLICATION

GRP can be used for any applications of any size or complexity,
Skylights, pipes, vents, stairs, walls and roof structures can all be weatherproofed or incorporated into the substrate with ease.
Pre-formed facia trims allow GRP to be adapted to nearly any application,
GRP can be used as a construction material for roofing furniture such as window casements and roof lights and is well suited to use on patios, walkways, roof gardens, gutters and as a lining for tanks, ponds and pools.

GRP has been used as a waterproofing material for over fifty 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 Boats entire lifespan of twenty years without the need for maintenance or replacement, This same level of performance is easily replicated on a domestic roof.

Long Life


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 excerpt from this report is included 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 more improved service life.
