GRP Fibreglass Flat Roofing in Osterley
Osterley is a residential area near Osterley Park, mostly 1920s and 1930s semi-detached houses with hipped tile roofs. Ridge tiles, lead flashing around chimneys and fascias and soffits are the usual weak spots after decades of weather.
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.
A typical GRP roof we install has an 18mm OSB3 deck, a single-ply fibreglass laminate, GRP edge trims and a durable topcoat. Finished this way, the roof is lightweight and seamless, copes well with hot and cold weather, and can last more than 20 years.
Grey is the most popular topcoat, though we can offer other colours to keep the roof in keeping with your building. For a free GRP roofing quote in Osterley, call 07467 757 367.
GRP Fibreglass Roofs for Homes and Businesses in Osterley
Many Osterley homes have a flat-roofed garage, porch or rear extension behind the hipped tile roof, and that is where GRP fibreglass comes into its own. Unlike felt, which can crack and blister as it ages, a GRP roof forms one seamless layer with no joints for water to exploit.
We install a single-ply GRP laminate over an 18mm OSB3 deck, with GRP edge trims and a tough topcoat to finish. Grey is the usual colour and works well alongside the tiles of an interwar semi, though other colours can be supplied if you prefer. Fitted properly, a GRP roof can last 20 years or more. It also suits dormers and balconies if you are planning a loft conversion. Our GRP service is available in Lampton and Heston as well.
Our Staines head office is about 8 miles from Osterley, and we regularly work on homes and businesses across the 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 the London Borough of Hounslow before work starts, and we are happy to talk this through with you.

GRP Fibreglass Roofs in Osterley: Your Questions Answered
Can you replace the felt on my Osterley porch roof with GRP?
Yes. Porches are well suited to GRP fibreglass. We strip the old covering, lay an 18mm OSB3 deck and apply a seamless single-ply GRP laminate with edge trims and topcoat. Grey is standard, other colours are available, and it can last 20 years or more.
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.
Is GRP better than felt for flat roofs in Osterley?
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 colours are available?
Most GRP roofs are finished with a grey topcoat, but other colours are available to suit your property.
How much does a GRP roof cost?
It depends on the size of the roof, the condition of the deck and access. We will look at the roof and give you a free, no-obligation quote.
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.
