V-Flow GRP Dry Valley Top Closure Slate – Lead Grey

The V-Flow Dry Valley Top Closure for slate replaces traditional lead or mortar at the ridge junction where two slate valleys meet. This flexible polyurethane unit creates a neat, waterproof seal that overlaps the valley troughs and sits under the slates to maintain the integrity of a dry-fix system.

Using a dedicated top closure is a practical call for the trade because it removes the need for complex lead dressing or wet trades at the highest point of the valley. It is designed to match the 70mm low-profile troughs used with natural or man-made slates, ensuring the entire installation remains maintenance-free and aesthetically consistent.
This component is part of the BBA-certified V-Flow range and is finished in lead grey to blend with the main valley sections. It provides a professional finish that significantly reduces fixing times on-site.
