GRP Fibreglass Roofing Specialists
Across Snodland & Tonbridge
Durable, seamless, and fully waterproof flat roof solutions. Installed by trusted, fully insured local experts.

We begin every project with a thorough inspection of your existing roof structure to ensure it can support the new installation. Our process involves removing all old, failing materials and replacing them with high-quality, moisture-resistant OSB3 tongue-and-groove decking, which provides a solid, stable base. We then apply the GRP laminate, consisting of high-strength resin and chopped strand matting, tailored to the specific local temperature conditions in Kent to ensure optimal curing. Once the base is set, we finish the surface with a pigmented, UV-resistant topcoat. This cold-applied system means no blowtorches or naked flames are required, significantly reducing fire risk during installation while ensuring a perfect, leak-free seal around every edge and trim.

Choosing a GRP system offers homeowners unmatched peace of mind through a range of practical benefits. The surface is 100% waterproof and completely seamless, meaning there are no joints or seams that can pull apart and leak over time. This makes it an ideal solution for properties situated in the Medway Valley and wider Kent areas where damp conditions are common. With a life expectancy often exceeding 30 years, GRP is maintenance-free and highly resistant to UV rays, impact, and heavy weather. It is also inherently fire-retardant, providing an extra layer of protection for your home compared to older roofing materials.

At Century Roofing & Building, we understand the importance of adhering to stringent building regulations. For all flat roof refurbishments, we ensure our work complies with Part L of the UK Building Regulations regarding thermal efficiency and insulation standards. Whether you are in Snodland, Halling, or West Malling, we calculate the correct roof falls to prevent standing water and ensure your project meets local planning and safety requirements. Our commitment to high-quality workmanship means you can trust that your new roof is both legally compliant and structurally sound.

Many customers ask if you can walk on a GRP roof, and the answer is yes, provided it is installed with the correct reinforcement for foot traffic, such as on a balcony. When comparing GRP to EPDM, GRP offers a superior aesthetic and can be colour-matched, whereas EPDM is a rubber membrane that relies on adhesive-bonded seams. Regarding lifespan, a professionally installed GRP roof using quality resins and OSB3 boards will comfortably last 30 years or more with minimal attention.
