Roof Valley Repairs and Installation

Roof valleys channel large volumes of rainwater down from intersecting roof slopes. When valleys corrode or crack, water penetrates the roof space quickly; we provide full installations and robust repair solutions.

When You Need Roof Valleys

Water leaks appearing in the loft directly underneath roof intersection points. Rust, holes, or cracks visible in metal valley linings. Debris and moss blockages causing water to overflow beneath roof tiles. Slipped or loose mortar bedding along the edges of your roof valleys.

How We Do It

We remove damaged tiles adjacent to the valley to expose the underlying trough. We strip out rusted metal or degraded felt valley linings and inspect the timber. We install high-specification lead or modern GRP valley systems securely. We re-bed edge tiles in fresh mortar and test drainage performance.

What to Expect

Valley repairs or replacements are normally completed within 1 day.
