Fibreglass (GRP) Flat Roofs in Northumberland

Fibreglass roofing, also known as GRP (Glass Reinforced Polyester) flat roofing, is a popular choice for both residential and commercial properties. Known for its strength, versatility, and low maintenance, GRP provides a dependable solution for safeguarding your property from the elements.

At Northumberland Roofing, we specialise in the installation and repair of GRP flat roofs, delivering a seamless, weatherproof finish built to last. GRP systems are fully waterproof, fire-resistant, and resistant to moss and algae — making them ideal for homes, extensions, garages, and commercial buildings across Northumberland, Newcastle, and Tyne and Wear. Whether you’re after a brand-new installation or expert repairs, our experienced team ensures top-quality results tailored to your needs.

We use the trusted Cromar Pro GRP Roofing System, renowned for its robust performance and longer lifespan compared to traditional felt roofing. Our detailed installation method includes applying a catalysed resin layer to OSB3-grade roof decking, followed by fibreglass matting, another resin coat, and finally a fire-retardant topcoat — resulting in a durable, weather-resistant, and visually appealing finish.

For repairs, we thoroughly assess the damage and provide targeted solutions to restore your roof’s integrity and extend its lifespan. Whether your property requires minor fixes or a more comprehensive solution, our team is equipped to handle projects of all sizes.
