Why Choose a Fibreglass Flat Roof?

Traditional flat roofs have a reputation for pooling water and splitting over time. Upgrading to a GRP (Glass Reinforced Plastic) roofing system eliminates these common issues. This liquid roofing application cures into a single, continuous membrane, meaning there are no seams or joints where water can penetrate.Exceptional Durability: Fibreglass is tough enough to walk on, making it ideal for balconies or roofs requiring regular access.Fully Waterproof: The seamless liquid application leaves zero weak points for leaks.Long-Lasting Performance: A correctly installed GRP roof can easily last for decades without the need for constant flat roof repairs.Maintenance-Free: Once the topcoat is applied, your new roof is highly resistant to moss, algae, and UV damage.Our Kent roofing contractors will assess your property to ensure a fibreglass flat roof is the perfect fit for your home's unique requirements.

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

How We Install Your GRP Liquid Roofing

A high-performance roofing system is only as good as its installation. We never cut corners, ensuring every layer is meticulously prepared and applied for maximum longevity.1. Strip and Prepare: We safely remove your old, failing roof covering and inspect the underlying timber joists for any signs of rot or structural weakness.2. Install New Decking: We lay fresh, moisture-resistant OSB3 timber boards to create a sturdy, perfectly flat foundation for the fibreglass.3. Apply Resin and Fibreglass Matting: Specially formulated base resin is rolled onto the decking, followed by high-quality fibreglass matting. This is consolidated to remove all air bubbles and form a solid, rigid layer.4. Add Trims and Topcoat: Once cured, we install edge trims to direct water efficiently into your gutters. Finally, a durable topcoat is applied in your chosen colour (usually dark grey) to provide ultimate UV and weather protection.

Common Questions About GRP Flat Roof Installations

How long will a GRP fibreglass roof last?When installed by Kent roofing experts like our team, a GRP roof can easily last in excess of 30 years. It is highly resistant to temperature fluctuations and physical impacts.Is fibreglass better than traditional felt?While modern felt systems have improved, GRP offers a superior, joint-free finish. Felt relies on bonded seams which can separate over time, whereas fibreglass is applied as a continuous liquid roofing layer, significantly reducing the risk of leaks.Can you repair an existing flat roof instead of replacing it?We always conduct a thorough inspection before recommending a full replacement. If the underlying timber is sound and the damage is localised, we can provide targeted flat roof repairs. However, if the roof has reached the end of its natural life, a new flat roof replacement in Dartford is the safest long-term investment.

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.
