GRP Flat Roofing

Glass-reinforced plastic, or GRP for short, is a strong, lightweight & durable material that has been developed to produce a water-resistant roofing membrane perfect for flat roofs.

As well as being used for flat roofs, GRP is used for a variety of other applications, including making boats, creating water holders & making & waterproofing ponds.

These additional applications show the material’s capabilities in managing water. GRP is highly water-resistant and does not let any moisture through.

What is GRP Fibre Glass?

GRP stands for glass-reinforced plastic, also known as fibreglass roofing. GRP is composed of resin with glass or fibrous strands that reinforce the roofing material.

GRP flat roofs begin with a layer of catalysed resin applied to roof decking (ideally OSB3 wood). A layer of fibreglass mating is laid on top, followed by another layer of catalysed resin to complete the system. Once cured, a fire retardant topcoat resin is applied to completely weatherproof the roof and give it a more attractive finish.

The Cost of a GRP Fibre Glass Flat roof

Many different factors alter the final cost of a GRP Roofing System. The main one is the size of the roof & the condition of the current roof, along with additional factors such as whether you’re having a complete fibreglass roof installed or having repairs done to your existing fibreglass flat roof.

When installing a flat roof, you need to consider the condition of what is there at the moment. If the current roof has strong foundations & is correctly structured, our team may not be required to create a decking or anchor points to a building.

If you have a flat roof fitted on a new garage or property extension, you will more than likely require framing, boarding and installation.

If you currently have a corrugated metal flat roof, there will likely be some structural work required to ensure your roof is fitted correctly, flat & water-resistant.
