GRP Fibreglass Flat Roofing in Putney
Putney combines Victorian terraces running up from the river with large Edwardian houses on Putney Hill and plenty of 20th-century flats. We regularly deal with slate roofs that have reached the end of their life, worn lead flashing and flat roofs over rear extensions here.
GRP, or glass reinforced plastic, is a polyester resin reinforced with chopped glass fibres to form a tough, 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. The result is a lightweight, seamless roof that handles temperature extremes well and can last for over 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 Putney, call 07467 757 367.
Where We Fit GRP Roofs in Putney
Extension Roofs
Kitchen, rear and side extensions with flat roofs are ideal for GRP, giving a neat, seamless finish.
Flat Roof Replacement
We strip old felt or failed coverings, renew the deck where needed and lay a new GRP roof.
Garages and Outbuildings
Replace tired felt on garages, sheds and outbuildings with a GRP roof that needs very little maintenance.
Dormer Roofs
GRP is lightweight and easy to form around upstands, making it well suited to dormer roofs on loft conversions.
Balconies and Roof Terraces
With the right deck and topcoat, GRP can create a hard-wearing waterproof surface for balconies and terraces.
Porches and Bay Roofs
Small flat roofs over porches and bay windows can be finished in GRP with matching edge trims.
Local GRP Fibreglass Roofs Specialists in Putney
Rear extension roofs are one of the most common jobs we see in Putney, and fibreglass is often the best way to renew them. A GRP roof forms one seamless surface, with no joints to open up as the roof expands and contracts through the seasons.
We lay single-ply GRP laminate over an 18mm OSB3 deck, then finish with GRP edge trims and a topcoat. Grey is the usual finish, and other colours are available on request. A well-installed fibreglass roof can last more than 20 years. It is also a good choice for dormers, garages, balconies and porches, so a single visit can often deal with more than one small roof on the same house. We fit GRP roofs across Putney and for homeowners in Barnes and Fulham.
Putney is roughly 13 miles from our head office in Staines, well within the area our roofers cover every week. Most like-for-like roof work does not need planning permission, but if your property is listed or in a conservation area it is worth checking with Wandsworth Council before work starts, and we are happy to talk this through with you.

GRP Fibreglass Roofs FAQs for Putney
How long does a fibreglass extension roof last in Putney?
Laid properly over a sound OSB3 deck, a GRP roof can last 20 years or more. Its lifespan also depends on keeping outlets clear and avoiding damage from foot traffic. We will explain how to look after your new Putney extension roof once it is finished.
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.
Is GRP better than felt for flat roofs in Putney?
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.
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.
What colours are available?
Most GRP roofs are finished with a grey topcoat, but other colours are available to suit your property.
