Understanding Your Roof Valley – What Goes Wrong?

Roof valleys are particularly vulnerable points because they handle a concentrated flow of water. Over time, various issues can compromise their integrity. Common problems include cracked or crumbling mortar between tiles or slates in a 'wet' valley, leading to water penetration. Lead valleys can suffer from 'fatigue' cracking due to thermal expansion and contraction, or they might have been poorly installed initially. Blockages from moss, leaves, or debris can also cause water to back up and overflow into your roof space. Even seemingly minor damage can escalate quickly, turning a small leak into a major headache. Our team understands these common failure points inside out.

Why Choose Kevington Roofing and Building LTD for Roof Valley Repairs?

Our Approach to Effective Valley Repair and Replacement

When you call Kevington Roofing for a valley repair in Gravesend, our process starts with a thorough, honest assessment. We don't just guess; we pinpoint the exact cause of the problem. Depending on the type of valley and the extent of the damage, we offer tailored solutions. This could involve careful re-pointing with a durable, weather-resistant mortar mix for tiled valleys. For lead valleys, we can carry out specialist lead welding and bossing for isolated cracks, or if the lead is severely degraded, we will recommend a full replacement with high-grade lead that will offer decades of protection. We also work with modern, robust GRP (fibreglass) lining systems or other appropriate materials to provide a seamless, waterproof finish, always choosing the best option for your specific roof and budget.

Roof Valley Repairs FAQ

Frequently Asked Questions

Got a leaking roof valley? Find answers to common questions about lead flashing, GRP valley replacements, and our expert repair services across Ramsden, Bromley, and Croydon & South London.

What are the main signs that I need a roof valley repair?

+

The most obvious sign is water staining on your ceiling, usually near the internal corners of your house. If you look at the roof from the ground, you might see cracked mortar, loose lead, or a build-up of leaves and moss in the valley. If water can't flow freely down the valley, it will eventually find a way into your home.

Should I choose a lead valley or a GRP fibreglass installation?

+

Both have their benefits. Lead is a traditional material that can last over 60 years if fitted correctly by a specialist. It’s great for heritage homes in Kent. GRP (fibreglass) is a modern alternative that is very durable and has no scrap value, which can be a deterrent to theft. We can talk you through both options to see which fits your budget and property style.

Why is my roof valley leaking?

+

Valleys take the highest volume of water on your roof. Leaks often happen because the lead has cracked over time due to expansion and contraction, or the mortar has perished. Sometimes, a simple blockage caused by debris can cause water to back up under the tiles. Our Ramsden roofing team can quickly find the fault and suggest the best fix.

How much does a valley flashing replacement cost in Bromley?

+

The cost depends on the length of the valley and the material you choose. A simple repair or clearing a blockage is relatively inexpensive. A full replacement involves stripping back the surrounding tiles, fitting new lining or lead, and making everything watertight again. We provide free, itemised quotes so you know the exact cost before we start.

Can you fix a leaking roof valley without replacing the whole roof?

+

Yes, most valley issues are localised. We can usually remove the tiles on either side of the valley, replace the old lead or liner, and then re-fit the tiles. It is a common maintenance task that can extend the life of your entire roof without the need for a full replacement.
