V-Flow GRP Over Batten Dry Valley, 3m – Lead Grey

The V-Flow GRP Dry Slate Valley replaces traditional, high-maintenance mortar-fixed valleys with a modern, dry-fix system. Designed specifically for slate roof coverings, it provides a maintenance-free way to discharge water from the roof while achieving a neat, close-cut appearance.

This system is a practical choice for refurbishments and new builds because it can cut fixing times by up to 50% compared to traditional methods. It is manufactured from glass-reinforced polyester with a UV-inhibiting film, ensuring it remains durable and weatherproof for decades without the risk of cracking or failing like mortar.
This valley can be installed as an Under Batten or Over Batten profile depending on the specific roof requirements. It is BBA certified and designed to withstand standard UK weather conditions when installed alongside appropriate eaves and top closures.
