GRP Fibreglass Flat Roofing in Cambridge
The CB1 side of Cambridge covers the Victorian terraces off Mill Road and around the station, along with newer apartment buildings and family homes towards Cherry Hinton. Slate roofs, rear additions, dormers and chimney stacks are common repair jobs here.
Glass reinforced plastic, known as GRP or fibreglass, combines polyester resin with chopped glass fibres to create a strong, waterproof laminate. It was first widely used for boats because it is flexible and does not corrode, and it is now one of the most popular flat roofing systems.
Our GRP roofs are typically built from a single-ply GRP laminate over an 18mm OSB3 deck, finished with GRP edge trims and a protective topcoat. Finished this way, the roof is lightweight and seamless, copes well with hot and cold weather, and can last more than 20 years.
Most GRP roofs are finished in grey, but other topcoat colours are available if you want the roof to match your property. For a free GRP roofing quote in Cambridge, call 07467 757 367.
GRP Fibreglass Roofs in Cambridge: What We See Locally
Dormers and rear additions are where GRP fibreglass is most useful on Cambridge’s Victorian terraces. Dormers are a common job in CB1, and older felt on rear additions often needs replacing.
We lay a single-ply GRP laminate over an 18mm OSB3 deck and finish with GRP edge trims and a topcoat. It is seamless and can last 20 years or more. The usual colour is grey, though others are available. GRP also suits garages, porches and balconies, including on family homes towards Cherry Hinton. On a tight terrace roof, a tidy installation with no loose joints matters, and GRP is well suited to it. We fit GRP roofs in Great Shelford and Duxford too.
Our second office serves Cambridgeshire and the neighbouring counties, so Cambridge is part of our regular working area. Like-for-like roof work does not usually need planning permission, but if your property is listed or in a conservation area it is worth checking with Cambridge City Council before work starts, and we are happy to talk this through with you.

GRP Fibreglass Roofs in Cambridge: Your Questions Answered
Is GRP a good choice for a dormer roof in Cambridge?
Yes. GRP fibreglass is seamless and can last 20 years or more, which suits dormers on Cambridge terraces. We fit it over a new 18mm OSB3 deck with trims and a topcoat, usually in grey, though other colours are available.
Is GRP better than felt for flat roofs in Cambridge?
GRP is seamless, so there are no joins for water to get through, and it does not need the regular maintenance that older felt roofs do. It is a popular upgrade when a felt roof fails.
What is a GRP fibreglass roof?
GRP stands for glass reinforced plastic. Resin and glass fibre matting are laid over a timber deck to form a single seamless, waterproof layer, finished with edge trims and a topcoat.
What colours are available?
Most GRP roofs are finished with a grey topcoat, but other colours are available to suit your property.
How long does a GRP roof last?
A properly installed GRP roof can last for over 20 years and shows very little sign of wear in that time.
Can GRP be laid over my existing flat roof?
Usually we strip the old covering and check the deck. If the deck is damaged or not suitable, we replace it with new OSB3 boards before laying the GRP.
