Our GRP Fibreglass Flat Roof Installation Process

A fibreglass roof is only as good as the installation behind it. We take a thorough, step-by-step approach to ensure your new flat roof performs flawlessly year after year.Structural Assessment: We begin by surveying your existing roof to check the underlying timber joists for any signs of rot, damp, or structural weakness.Strip and Prepare: Our team carefully removes the old roofing material, disposing of it responsibly, and prepares the area for the new waterproof roofing systems.Decking Installation: We lay down high-quality, interlocking OSB3 moisture-resistant timber decking, creating a solid, stable base for the fibreglass.Resin and Matting: A layer of specially formulated glass fibre matting is applied and meticulously saturated with a high-performance liquid resin to form a seamless barrier.Protective Topcoat: Once the resin has fully cured, we finish the roof with a tough, UV-resistant topcoat, available in various colours to match your property perfectly.

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

Why Choose a Seamless GRP Roof Membrane?

Upgrading to a GRP fibreglass roofing system offers a wealth of long-term benefits for homeowners in Warlingham. First and foremost is its incredible longevity. Unlike traditional felt that may need replacing every 10 to 15 years, a professionally installed GRP roof often lasts over 30 years with minimal maintenance.Because the system is cold-applied in liquid form, it cures without any joints or seams. This eliminates the weak points where water typically finds its way into a property. It is also exceptionally impact-resistant, meaning it will not easily tear or puncture if a branch falls on it or if window cleaners need to stand on it. Furthermore, the materials used are completely fire-retardant and UV-stable, ensuring your seamless roof membrane will not degrade, crack, or blister in the summer sun.By combining our fibreglass installations with modern thermal insulation boards, we can also drastically improve your property's thermal efficiency, keeping your extension warmer in the winter and cooler in the summer.Protect your property with a modern waterproof roofing system.

Frequently Asked Questions About Fibreglass Roofs

How much does a new flat roof installation cost in Warlingham?The cost of a GRP fibreglass roof depends on the size of the area, the condition of the underlying timber decking, and whether thermal insulation upgrades are required. We provide free, transparent quotes tailored to your specific property after a thorough inspection.Can I walk on a GRP fibreglass roof?Yes. A standard GRP roof is tough enough to withstand occasional foot traffic for general maintenance, such as window cleaning. If you plan to use the area as a regular balcony or terrace, we can install a heavier-grade glass fibre matting and a non-slip topcoat for extra safety and durability.Is fibreglass better than traditional felt roofing?In almost all cases, yes. While felt is initially cheaper, it has a shorter lifespan, is prone to blistering in the heat, and has seams that can eventually fail. Glass reinforced plastic is completely seamless, highly impact-resistant, and can easily outlast traditional felt by decades.

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.
