Our Seamless GRP Installation Process

Installing a long-lasting fibreglass flat roof requires precision, high-quality materials, and expert knowledge. We never rely on unknown subcontractors. Our directly employed roofing staff manage every stage of your project to guarantee the highest standards of workmanship from start to finish.The process begins with a comprehensive inspection of your existing roof deck. We carefully strip away the old materials and assess the underlying timber joists for any hidden rot or water damage. Once the core structure is deemed safe and secure, we install fresh, high-grade OSB3 timber decking boards to create a solid foundation for the new system.We then apply the cold-applied GRP system. This involves laying a specially formulated resin alongside tough fibreglass matting to form an incredibly strong, unified layer. Finally, a UV-resistant topcoat is added. This fire-retardant finishing layer ensures your new roof remains weatherproof and visually appealing for decades to come.

Frequently Asked Questions About Fibreglass Roofing

How long does a GRP fibreglass roof actually last?When installed correctly by experienced professionals, a high-quality GRP roof can easily last for several decades. It far outlasts traditional felt roofing, which typically needs replacing every 10 to 15 years.Is GRP better than EPDM rubber or traditional felt?Fibreglass is incredibly tough and visually appealing. Traditional felt often fails at the seams, leading to leaks. While EPDM rubber roofing is a fantastic, flexible option for many flat roofs, GRP is generally superior if the area will experience regular foot traffic, such as a balcony.Do you offer emergency call-outs for leaking roofs?Yes, if your current flat roof has failed and water is entering your property, we offer fast response emergency roof repairs to secure your home and prevent further internal damage before planning a full replacement.

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.
