Our Seamless GRP Installation Process

We believe in doing things right the first time. A fibreglass roof is only as good as the preparation and materials used, which is why we follow a rigorous, step-by-step installation process. By taking the time to properly prepare the underlying structure, we ensure your new roof will remain watertight for decades.Structural Assessment: Every project starts with a thorough inspection of your existing roof to identify any hidden rot or structural issues within the timber joists.Complete Strip and Decking: We carefully remove your old felt and safely dispose of it. Next, we install high-quality, interlocking OSB3 moisture-resistant decking to create a rigid, perfectly flat foundation.Resin and Matting Application: A specialist layer of glass fibre matting is laid out and completely saturated with a high-performance liquid resin. Because it is cold-applied, there is no need for dangerous blowtorches on your property.Curing and Topcoat: Once the resin cures into a solid, seamless layer, we apply a UV-resistant topcoat in your chosen colour. This protective seal ensures the roof remains flexible and entirely weatherproof.Ready to upgrade your failing flat roof?

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

Why Upgrade to a Fibreglass Flat Roof?

Homeowners across Caterham and Surrey are increasingly choosing GRP over traditional roofing materials, and it is easy to see why. Glass Reinforced Plastic is an incredibly robust material originally developed for the marine industry, making it more than capable of handling the toughest UK weather conditions.Incredible Longevity: When installed correctly by our seasoned professionals, a GRP flat roof can easily last in excess of 30 years without deteriorating or breaking down.100% Seamless Finish: Traditional felt roofs fail at the seams and joints where water eventually finds a way in. Fibreglass is laid as a single, continuous membrane, meaning water has absolutely nowhere to penetrate.Impact and Traffic Resistant: GRP sets incredibly hard. It is highly resistant to impact damage from falling branches, safely resists foot traffic (making it perfect for balconies), and deters vandalism.Thermal Efficiency: Modern flat roofing presents an excellent opportunity to upgrade your home's insulation. By pairing a new GRP roof with warm roof insulation boards, you can dramatically improve the thermal efficiency of your property and lower your seasonal heating bills.

Meeting Local Authority Building Regulations

Navigating the red tape of local planning permissions and building control can be stressful for any homeowner. As trusted local roofing experts, Kevington Roofing and Building LTD actively manages the compliance aspect for you. If your flat roof replacement involves updating more than 50% of the total roof area, UK Building Regulations (Part L) typically require upgrading the thermal insulation at the same time to modern standards.We are highly experienced in designing and installing compliant warm roof systems that meet all current Surrey and Tandridge local authority requirements. As a fully insured and Registered UK Company (No: 12676001), we guarantee all our work is completed safely, legally, and to the highest professional standards. We never rely on unknown subcontractors; every installation is carried out by our own extensively trained, directly employed staff to ensure unmatched quality control.

How long does a GRP flat roof last?

We understand that investing in a new roof is a significant financial decision. Here are some of the most common questions our Caterham customers ask us regarding our professional GRP fibreglass installations.How long does a GRP flat roof last?A professionally installed GRP roof is incredibly durable and typically lasts well over 30 years. With proper basic maintenance, many fibreglass roofs can easily exceed this lifespan, making them a highly cost-effective long-term investment compared to traditional felt.Is fibreglass better than traditional felt roofing?Yes. While felt is often cheaper initially, it is highly prone to blistering, splitting, and UV degradation, usually needing total replacement every 10 to 15 years. GRP provides a completely seamless, impact-resistant, and visually appealing modern finish that outlasts felt by decades.Can you install a GRP roof in winter?Because the resin curing process relies on specific temperature conditions and absolute dryness, we carefully monitor the local weather forecast. We successfully install GRP year-round across Surrey by utilizing dry, mild days and advanced fast-curing resin formulations.

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.
