How We Install Your Seamless Fibreglass Roof

A high-quality flat roof relies on meticulous preparation and expert application. We manage every stage of the process to ensure your new GRP roof performs flawlessly for decades.Structural Deck Replacement: We start by stripping away the old, failing roof covering. We then install fresh, high-quality timber decking (typically OSB3 boards) to create a solid, structurally sound foundation.Applying the Resin and Matting: A specially formulated base coat of resin is applied, followed by layers of fibreglass matting. This creates a flexible yet incredibly tough, seamless barrier over the entire roof area.Weather-Resistant Topcoat: Once the base layer has cured, we apply a durable, coloured topcoat. This final layer protects the roof from UV rays and extreme weather conditions.Edge Trims and Detailing: We install bespoke pre-formed fibreglass edge trims to ensure rainwater is directed efficiently into your gutters, preventing pooling and leaks.

Why Choose Kevington for GRP Fibreglass Roofing in Swanley & Kent?

Why Choose Fibreglass for Your Flat Roof?

Investing in a GRP fibreglass roof brings long-term value and peace of mind to homeowners in Sevenoaks. Unlike traditional felt that can blister, crack, and fail over time, glass reinforced plastic is engineered to withstand the harshest British weather.One of the main advantages is the completely seamless finish. Without any joints or overlapping seams, the risk of water ingress is drastically reduced. Once installed, a GRP roof is virtually maintenance-free and provides excellent longevity. The material is also highly versatile, meaning it can be moulded around complex roof shapes, rooflights, and ventilation pipes with ease.Furthermore, fibreglass is strong enough to withstand regular foot traffic. If you are planning a balcony or roof terrace, we can apply a textured, non-slip finish to the topcoat, creating a safe and functional outdoor space. Book a free roof inspection today by calling 01689 663319 to see if GRP is right for your home.

Frequently Asked Questions About GRP Roofing

How long does a GRP flat roof last?When installed correctly onto a brand-new timber deck, a GRP fibreglass roof can easily last for several decades. Its durable, weather-resistant nature makes it one of the most cost-effective and long-lasting flat roofing materials available in the UK.Can I walk on a fibreglass roof?Yes. Fibreglass is incredibly strong and can easily support regular foot traffic without taking damage. If you intend to use the roof as a balcony or terrace, let us know during the quotation phase, and we will apply a specialised non-slip finish for added safety.Is a GRP roof better than traditional felt?For most domestic and commercial applications, yes. While traditional felt is often cheaper initially, it has a shorter lifespan and relies on bonded seams that can degrade, blister, and leak. GRP provides a completely seamless, joint-free surface that is much more resistant to weathering and UV damage.Do you provide free quotes in Sevenoaks?Absolutely.

"Reliable and prompt - the Kevington team was able to view the property and provide options and transparent, itemised quotes on the same day I called. After deciding what level of work I wanted done, they returned soon after to carry out the roof repairs to a high standard without me even needing to be there."

"Highly recommended! Great price! First class job. Nothing was too much for these lads, very polite, got the job done and more. When they had finished they cleaned up that well, even took some of my own rubbish away for me. Well done lads! Not often you get a good, honest local roofer anymore! Thanks again."

GRP Fibreglass FAQs

Frequently Asked Questions About GRP Flat Roofing

Got questions about upgrading or repairing your flat roof? Kevington Roofing and Building LTD provides expert answers on our durable, cold-applied liquid membrane systems for homes across Croydon & South London, Swanley, Sevenoaks, and Kent.

How much does a new GRP fibreglass roof cost in Swanley?

+

The cost of a fibreglass roof replacement in Kent depends on the size of the area and the condition of the underlying timbers. Generally, while the initial cost is slightly higher than felt, the fact that it lasts twice as long makes it the most cost-effective flat roof installation in the long run. We provide free, itemised quotes so you can see exactly where your money is going.

Can a GRP roof be installed in any weather?

+

Fibreglass needs dry conditions to cure correctly. While we can work throughout the year in Swanley, we carefully monitor the weather. We will never start a resin application if rain is forecast, as this would compromise the waterproof seal. Our team uses temporary coverings to keep your home dry at all times during the process.

Is GRP roofing noisy when it rains?

+

This is a common myth. When installed correctly with high-quality OSB3 decking and proper insulation, a GRP roof is no noisier than any other roofing material. In fact, many homeowners find it quieter than old thin felt roofs because of the solid timber base we install underneath the laminate.

How long will the installation take?

+

Most domestic flat roofs in Swanley, such as a standard garage or kitchen extension, can be completed in one to two days. We aim to work efficiently to minimise disruption to your daily routine, and we always make sure the site is safe and secure at the end of each day.
