Introduction to GRP Roofing

GRP roofing, a robust system made from a combination of fibreglass and polyester resin, is acclaimed for its resilience and versatility. It's a preferred choice for both commercial and residential structures due to its strength, ability to endure extreme weather, UV resistance, and low maintenance. This roofing type, also known as fibreglass roofing, boasts a long lifespan, often exceeding 30 years.

Installation Guide Overview
Installing a GRP flat roof demands thorough planning and preparation. Key steps include weather checking, ensuring dry conditions, and inspecting the existing decking for moisture or rot. The installation involves laying a base resin layer, followed by fibreglass matting and a final topcoat for a polished look. Our guide provides detailed instructions for each step, ensuring a high-quality and durable finish.

Safety and Pre-Installation Checks
Prior to installation, several safety checks are necessary. These include ensuring no presence of asbestos, maintaining a smoke-free environment due to the use of flammable chemicals, confirming the stability of the roof for walking, and preparing scaffolding or other secure systems for working at height. A thorough materials check is also crucial to ensure all necessary supplies are available and accessible.

Edge Trim Installation
Our GRP-made edge trims are essential for shaping, protecting, and enhancing the aesthetic of your flat roof. They are installed after the decking and insulation but before the laminate, covering the roof's edges and the interface between the wall and roof. This step is vital for proper rainwater channeling and adding a finished look to your roof.

Laminating Process
The laminating phase is critical for creating a high-quality, water-resistant barrier. Key tools for this process include a polyester roller, paddle roller, and a mixing bucket. It's important to carefully plan the areas to laminate, especially for large or complex roofs, to avoid putting weight on fresh laminate. Beginners are advised to practice on smaller areas first to ensure a high-quality finish.
