A roof valley is the channel formed where two sloping roof sections meet. Its job is to collect a large volume of water from both slopes and guide it safely down into your guttering. Because they handle so much water, they are a common area for leaks. This can be caused by old, cracked lead, damage from slipped tiles, or a build-up of moss and debris that stops water from flowing freely, forcing it under the tiles.

The most obvious sign is water damage inside your home, such as damp patches or stains on the ceiling directly below where the valley is. You might also notice slipped or broken tiles in the valley area itself when looking from the ground. Over time, the old mortar bedding can crumble away, or the lead lining can split, and both are clear signs that a professional repair is needed before more serious damage occurs to the roof timbers.

A professional valley repair is a detailed job. We start by carefully stripping the tiles on both sides of the valley to fully expose the area. We then remove the old, failing materials – whether it’s old lead, cement, or rotten wooden battens. After cleaning and preparing the area, we install a new, robust valley lining. This is often done using new lead, which is expertly shaped to fit, or a modern GRP fibreglass valley trough. Finally, we re-lay the tiles, cutting them precisely to ensure a neat, watertight finish.

Yes, there is. While lead is the traditional material and extremely durable, a very popular and effective modern alternative is a pre-formed GRP (Glass Reinforced Plastic) valley trough. These are lightweight, tough, and provide a seamless, smooth channel for water to run off. They are a great, long-lasting solution and can be a more cost-effective choice than lead, without compromising on performance.

The main benefit is peace of mind. A roof valley is a critical part of your roof's drainage system. A DIY or poor-quality repair is one of the most common causes of major roof leaks, as it can be tricky to get everything watertight. A professional repair done by an experienced roofer ensures the job is done right the first time, using the correct materials and techniques. This prevents water from getting into your roof space, protecting your timbers from rot and your ceilings from damage, saving you much more money and stress in the long run.
