Why Select GRP Fiberglass Roofing?
- Seamless Finish – Offering a stylish solution to welded and glued alternatives, GRP fibreglass’ seamless finish ensures minimal weakness. Its visually appealing, smooth surface cannot be broken through regular use.
- Maintenance-Free – GPR roofing creates a long-lasting, impervious membrane across all applications, meaning, when applied correctly, they require no maintenance unless significantly damaged, or in need of cleaning.
- Long-Lasting – With Topseal warranties offered for up to 45 years, and most roofs using GRP expected to last for up to a century, this material is an excellent option for those seeking a long-lasting, low-maintenance solution.
- Versatile – GRP’s ability to mould to even the most complex shapes allows for the creation of roofs in line with all existing roof and property structures. Its versatile and hardwearing nature allows for its further application on spaces such as balconies.
- UV Resistant – Fibreglass roofs are extremely resistant to UV damage, allowing them to remain structurally sound over extended periods of time, even in spaces subject to continued exposure.
- Insulating – In addition to being sustainable, both ‘regular’ fibreglass and green roofs offer the property below a significant level of insulation and protection, reducing electricity bills throughout the year.

Fibreglass Roofing FAQ’s
What is GRP?
GRP stands for ‘Glass Reinforced Plastic’, a modern roofing material composed of polyester resin, and reinforced by chopped strand mat glass fibres. GRP Is commonly used in roofing and construction due to its strength as a composite, and its lightweight. Though it has been in use since the 1940s, GRP has been further developed to function as a durable, lightweight, flexible, fully reinforced, and waterproof material capable of being moulded to any shape.
Today, GRP is most commonly used in the creation of flat roofs, offering an easily repairable, flexible, fast-drying, fully waterproof roofing surface.
How Much Does a Fibreglass Roof Cost?
The cost of a fibreglass or GRP roof is highly dependent on a number of factors - primarily whether the structure is being built from scratch, or is simply an existing roof system in need of alteration or repair. In addition to this, those looking to purchase a fibreglass roof should consider the square footage of the roof, the complexity of the project, the system used, and, of course, the professionals hired to complete construction.
It is important to ensure that the professional selected to install a fibreglass roof is accredited and skilled, as, although GRP materials are hard-wearing, flat roofs created using this material incorrectly can fast require significant repairs.
Although fibreglass flat roofs are generally slightly more expensive than EPDM or rubber roofing systems, they offer an increased value for money in their longevity, weather resistance, and low-maintenance nature.

What's the best flat roof system?
There are a number of flat roofing systems on the market, with the most well-known generally being EPDM, rubber, PVC, and GRP/fibreglass. For many across the UK, including our roofing team, GRP is the ideal choice, offering an unrivalled level of value for money. GRP roofs, when correctly installed by skilled professionals, offer a superior level of robustness and versatility, offering none of the weak points seen in its welded and glued competitors. In addition to this, GRP is generally considered to be very aesthetically pleasing, with renowned brands such as Topseal offering thousands of colour combinations to match a wide variety of applications, from new-build balconies, to period property roofs.
Can GRP roofs crack?
When correctly installed by a professional team, GRP roofs very rarely experience cracking, and, in fact, should be subject to little-to-no maintenance in their decades-long lifespans. Where cracking does occur, it may be a result of age, excessive expansion and contraction as a result of exposure to heat on hot days, or incorrect initial installation, where, for example, too little top-coat was applied. A crack in a GRP roof can generally be repaired by a trained professional, with methods used varying according to the severity of the damage.

Can I walk on a Fibreglass roof?
Fibreglass roofs can generally be walked on, making them extremely versatile, and suitable for use on both domestic and commercial properties. With GRP generally being suitable for this application, it may also be used on surfaces such as balconies. The amount of material and number of layers applied generally corresponds to the amount of foot traffic expected for a specific area.

What are the benefits of having a green roof?
Green roofs are both an aesthetically pleasing, and functional addition to any flat-roofed property. Offering the traditional benefits of a fibreglass roof alongside a number of unique upsides added by the presence of vegetation, green roofs provide shade, insulation, and protection to the properties upon which they are situated.
Taking advantage of Topseal’s long-lasting, fully-waterproof nature, GreenTop allows for the creation of a bespoke natural space, from simple turf to wildflower gardens - adding sound insulation, and protecting the property below from temperature fluctuation.

Do green roofs really work?
Green roofs do really work. Whether taking the form of simple turf, or a wildflower garden, these unique additions to flat rooftops offer a number of ‘working’ benefits to the properties upon which they are situated. One of the primary ways in which a green roof ‘works’ is its reduction in the roof’s exposure to the elements, helping ensure that the GRP membrane beneath the vegetation lasts for an extended period of time. In addition to this, green roofs offer further protection from the elements in the form of insulation and fire retardation, helping reduce the amount of energy required to heat the property below and to further ensure the safety of its residents.
Can GRP roofs be repaired?
GRP roofs, in theory, should not need to be repaired within their allocated lifespan - which for many brands, is up to 50 years. When prepared and installed correctly, GRP roofs should be completely resistant to corrosion, rot, and general degradation - however, if installed incorrectly, issues such as pinholes and cracking may occur. These issues pose concerts surrounding watertightness and further damage, meaning they should be dealt with quickly.
Luckily, GRP roofs, in most circumstances, can be repaired. This job should be undertaken by an accredited professional, who will alter their method to fit the issue present. Emergency repairs should be undertaken where water is visibly leaking, or during heavy rainfall.
How long will a GRP roof last?
Cured fibreglass or GRP does not rot or corrode, meaning that when installed correctly, the guaranteed lifespan of a roof of this type can be anywhere from 20 to 45 years depending on the system or brand selected. Outside of this guarantee, some brands, such as topseal, are thought to have an expected lifespan of up to a century.
In order to ensure your GRP roof lives up to its potential in terms of longevity, it is vital to ensure that it is prepared and installed correctly. The best way to do this is to bring on board an accredited professional, with experience in installing GRP/fibreglass roofs.
Is Fibreglass roof better than felt?
Fibreglass is a significantly more durable and versatile roofing material than felt and is particularly suited to the flat-roof application. Within this context, the nature of the material makes it vastly superior to felt. Whereas alternative materials possess weak-points in the form of glued joints and welds, or even in their composition, fibreglass is a seamlessly applied, fully waterproof, and highly resistant surface when installed correctly, allowing it to outlast its competitors, often by decades.
