Fibreglass roofing, also known as GRP (Glass Reinforced Plastic) roofing, is a strong, lightweight, and seamless flat roofing system made from layers of resin and glass fibres. Once cured, it forms a solid, waterproof surface that is highly resistant to weather, UV rays, and impact. Ideal for domestic and commercial properties, fibreglass roofing offers a sleek finish with minimal maintenance and a typical lifespan of over 25 years. It's especially popular for extensions, garages, balconies, and walkways due to its clean look and reliable performance.
