Our Seamless GRP Fibreglass Installation Process

A high-quality flat roof relies entirely on the precision of its installation. We never cut corners or use unknown subcontractors. Our directly employed roofing specialists follow a rigorous process to ensure every GRP roof we install in Gravesend performs flawlessly.Structural Assessment & Preparation: We begin by stripping back your old, failing roof to expose the structural joists. We check for hidden water ingress or timber rot, ensuring your roof's foundations are entirely sound.Installing the Decking: We lay high-grade, moisture-resistant OSB3 timber decking. This creates a strong, clean platform essential for the fibreglass resin to bond correctly.Applying the Fibreglass Matting & Resin: Next, we apply the GRP layer—a matrix of fibreglass matting saturated in a highly durable, liquid resin. Because it is cold-applied, there is no need for dangerous hot works or blowtorches on your property.The Protective Topcoat: Finally, we apply a specially formulated, fire-retardant topcoat and install neat, weatherproof trims. This cures to form a seamless, hardened surface that naturally repels rainwater.Whether you need a full replacement for a leaking garage or are planning a brand-new build over the summer, our process guarantees a flawless finish.

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

Why Choose GRP Fibreglass for Your Flat Roof?

Homeowners across Gravesham are increasingly choosing GRP over traditional roofing materials. Here is why fibreglass is an outstanding, long-term investment for your home:Completely Seamless: Traditional flat roofs often fail at the joints where sheets meet. GRP is poured and cured in place, creating a single, continuous waterproof membrane with zero vulnerable seams.Exceptional Durability: Fibreglass is incredibly tough. It resists tearing, splitting, and UV degradation. It can even be specially reinforced to handle regular foot traffic, making it the perfect choice for modern balconies or roof terraces.Low Maintenance: Once installed, a GRP flat roof requires almost no upkeep. There are no loose stones to wash away into your gutters and no moss-prone surfaces, keeping your roofline looking clean and modern.Thermally Efficient: When combined with modern warm roof insulation layers, a GRP system helps dramatically improve your home's thermal efficiency, keeping your extension warm in the winter and cool in the summer.Protect your property from unpredictable weather.

Frequently Asked Questions About GRP Flat Roofs

How long does a GRP fibreglass roof last?When installed correctly by experienced professionals using high-quality resins and topcoats, a GRP flat roof can easily last upwards of 25 to 30 years without deteriorating, significantly outperforming traditional roofing felt.Is a fibreglass roof noisy when it rains?No more so than any other type of flat roof. If your roof space incorporates the correct modern insulation boards and ceiling plasterboard underneath, the sound of heavy rain is highly muffled and rarely noticeable.Can I safely walk on a fibreglass flat roof?Yes. While standard GRP roofs can easily withstand occasional foot traffic for window cleaning or maintenance, we can also install a heavier-grade fibreglass matting with a non-slip finish if you intend to use the area as a permanent balcony or terrace.

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.
