GRP valley troughs provide a durable, maintenance-free solution for channelling rainwater safely from roof valleys on pitched roofing systems. Manufactured from glass reinforced plastic, they offer a lightweight alternative to traditional lead valleys while delivering excellent weather resistance and long-lasting performance on both new build and refurbishment projects.
Our range includes GRP valley troughs in a variety of profiles and sizes to suit different roof pitches and tile types. Designed for straightforward installation and compatibility with concrete and clay roof tiles, these valley systems help create a reliable, watertight roof detail with a clean, professional finish.
