Our Cold-Applied GRP Roofing Process

Installing a durable flat roof requires meticulous preparation and technical skill. Our installation process is designed to ensure maximum longevity and structural integrity for every Westminster property we work on.Comprehensive Assessment: We often begin with a drone roof survey to safely assess the condition of your existing roof structure and timbers without the immediate need for scaffolding.Decking Preparation: We strip back the old, failed materials. If the underlying structural timbers are compromised by water ingress, we replace them before laying new, structurally sound OSB3 decking boards.Resin and Matting Application: The cold-applied fibreglass matting and high-quality resins are bonded directly to the new deck. This creates a tough, continuous layer with zero seams or joints where water could potentially penetrate.UV-Resistant Topcoat: Finally, a highly durable, UV-resistant topcoat is applied. This seals the system and provides a neat, protective, and long-lasting finish.

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

Why Choose Fibreglass Flat Roofs for Your Property?

Traditional felt roofs often deteriorate under harsh sunlight or heavy rain, leading to costly leaks and internal damage. GRP roofing provides a superior alternative with several distinct advantages for homeowners and commercial clients alike.Exceptional Durability: Once cured, glass reinforced plastic is incredibly tough. It easily withstands foot traffic, making it an ideal choice for flat roofs, balconies, and roof terraces.Completely Seamless: Because the liquid resin moulds precisely to the shape of your roof, there are no vulnerable joints or welded seams to fail over time.Maintenance-Free: GRP systems require virtually no upkeep and are highly resistant to moss growth, UV degradation, and thermal cracking.Kerb Appeal: Available in sleek finishes, fibreglass roofing adds a modern, clean aesthetic to extensions, dormers, and garages.If you have noticed damp patches on your ceiling, contact our emergency repair team on 01689 663319 to secure your property and prevent further internal damage.

When installed correctly onto a well-prepared timber deck, a fibreglass roof can last for 30 years or more, vastly outperforming traditional felt systems.Can fibreglass be applied over an existing roof covering? No. For the resin system to bond properly and comply with building regulations, we must completely strip the old roof covering and install fresh, dry OSB decking.Is a GRP roof safe to walk on?

"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.
