GRP Fibreglass Flat Roofing in Boston
Boston is a historic port town dominated by the tower of St Botolph’s Church, known as the Boston Stump, with Georgian and Victorian buildings and large areas of newer housing. Exposed roofs here need regular ridge, verge and chimney checks.
GRP, or glass reinforced plastic, is a polyester resin reinforced with chopped glass fibres to form a tough, waterproof laminate. Originally popular in boat building for its strength and resistance to corrosion, it has become a leading choice for flat roofs.
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 Boston, call 07467 757 367.
GRP Fibreglass Roofs for Homes and Businesses in Boston
Boston’s newer housing includes many flat-roofed extensions, garages, dormers and porches, and when their original coverings begin to fail, GRP fibreglass is our usual recommendation. It gives a seamless finish, with no joints for wind or water to work at.
We lay a single-ply GRP laminate over an 18mm OSB3 deck, add GRP edge trims and finish with a topcoat. The usual colour is grey, with other colours available. With proper installation, a GRP roof can last 20 years or more. It also suits balconies. On older Georgian or Victorian buildings, we will advise whether GRP is suitable or whether a more traditional covering is appropriate. Renewing the deck as part of the job means any soft boards are replaced too. We install GRP roofs for homeowners in Sleaford and Holbeach as well.
Boston is looked after by our second office, which covers Cambridgeshire, Lincolnshire, Norfolk, Rutland and the surrounding area. 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 Boston Borough Council before work starts, and we are happy to talk this through with you.

Common Questions About GRP Fibreglass Roofs in Boston
What is involved in fitting a GRP roof on a Boston extension?
We remove the old covering, lay a new 18mm OSB3 deck, apply a single-ply GRP laminate and fit GRP edge trims, then finish with a topcoat. The result is a seamless roof for your Boston extension that can last 20 years or more.
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.
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.
Is GRP better than felt for flat roofs in Boston?
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.
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.
