How Not to Lay a GRP RoofSteven Dickinson
Have a watch of this video on how a GRP roof shouldn’t be laid.
There are two problems with GRP flat roofs. Firstly it’s very difficult to get a skilled person to lay GRP correctly – you really need to have been laying GRP for some time before you understand and can prevent any problems.
This is a brand-new GRP flat roof and we’ve got a sort of admit from the very beginning; we don’t like GRP for roofing. GRP is an excellent material but not for roofs.
What is GRP?
GRP stands for ‘Glass Reinforced Plastic’ a material made from a polyester resin, which is reinforced by chopped strand mat glass fibres to form a GRP laminate. It is a very popular composite material to use due to the fact that not only is it very strong but also surprisingly light.
GRP Roofs and Noise
One of the complaints we get an awful lot with a GRP roof is the noise. Observe in the video the noise the roof makes and imagine this same noise repated 1000 times over in 1 second during heavy rainfall.
GRP is now available on the open market and most DIY installers are having a go at it and calling themselves roofing experts. GRP really does need to be laid by an expert. The detailing you can see in this video is really poor.
