Our Seamless Fibreglass Roof Installation Process

A successful GRP roof relies entirely on the quality of the installation and the preparation of the decking beneath it. We never cut corners, ensuring every stage is carried out to the highest industry standards.Initial Inspection: We assess the current state of your roof. We often use advanced drone roof surveys to identify structural faults without unnecessary scaffolding.Stripping and Preparation: We carefully remove your old, failing roof covering and inspect the underlying timber joists for any signs of water damage or rot.Installing the Decking: We lay high-grade OSB3 timber decking to create a perfectly solid, dry, and clean foundation for the fibreglass.Resin and Matting Application: We apply layers of specially formulated catalysed resin and chopped strand glass fibre matting, creating a tough, completely bonded waterproof layer.Durable Topcoat Finish: Finally, a protective, fire-retardant topcoat is added. This cures to form a seamless, weatherproof shell that will protect your property for decades.Our direct-employed roofing experts handle every detail, ensuring your new flat roof is perfectly pitched to prevent pooling water.

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

Why Choose GRP for Your Horley Home?

Upgrading to a glass-reinforced plastic roof offers several distinct advantages over traditional flat roofing materials like standard felt or asphalt.Completely Seamless: Because GRP is applied as a liquid, there are no joints, seams, or weak points where water can penetrate. This results in truly leak-proof flat roofs.Outstanding Longevity: When professionally installed, a fibreglass roof can last for decades without requiring extensive roof repairs or maintenance.Highly Durable: The hardened topcoat is robust enough to withstand heavy foot traffic, making it an ideal choice for balconies or roof terraces.Fire Retardant and Safe: Our GRP systems meet strict fire safety ratings. Furthermore, the installation process is entirely cold-applied, eliminating the risks associated with blowtorches and hot works.Investing in premium Surrey roofing solutions that perform year after year ultimately saves you money on constant patch repairs and emergency call-outs.

Frequently Asked Questions About GRP Flat Roofs

How long does a GRP fibreglass roof last?With professional installation and proper decking preparation, a fibreglass roof can easily last upwards of 30 years. It provides a highly durable, maintenance-free finish that heavily outperforms traditional mineral felt.Is fibreglass better than an EPDM rubber roof?Both are excellent modern alternatives to felt. GRP is highly rigid, making it perfect for balconies or areas with foot traffic, and it is entirely seamless. EPDM is highly flexible and great for large, simple flat areas. We can advise on the best option for your specific property during a site visit.Can you install GRP in the winter?GRP systems require dry conditions and specific temperature ranges for the resin to cure properly. While we can install them year-round, we carefully monitor the weather and may use seasonal additives to ensure a perfect finish during colder Surrey winters.

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.
