Roof Valley Repairs in Oxford That Stop the Leak
Leaking roof valley in Oxford? Premier Roofing Oxford repairs and re-lines roof valleys where two roof slopes meet. A lead valley repair typically costs £90–£225, a full lead valley replacement £550–£675, and most valley jobs are completed in one day.
A roof valley carries more water than any other part of the roof, so when the lead splits, the liner wears out or leaves and moss block it, water quickly finds its way inside. Valley leaks often show up some distance from the valley itself. We trace the real cause and repair it properly, and we are rated 4.9★ from 190+ Google reviews.

Signs Your Roof Valley Is Failing
Valley problems are easy to miss from the ground, but they are one of the most common causes of roof leaks in Oxfordshire.
Lead Valleys vs Modern Valley Liners
Traditional lead valleys are formed from code lead, lapped and dressed into the valley. Done properly, lead lasts for decades and suits period and conservation roofs, which is why it is still the first choice on many Oxford homes.
Modern valley liners such as GRP are quicker to fit and lower cost, and can be a good option on many modern tiled roofs. We will recommend the right lining for your roof and budget.
- Lead: traditional, very long-lasting, ideal for slate and period roofs
- Modern liners: cost-effective and quick to install
- Both: correctly lapped and fixed so water runs freely

Roof Valley FAQs
How much does a roof valley repair cost?

What is a roof valley?
A roof valley is the internal angle where two roof slopes meet. It is lined with lead or another valley liner so the large volume of rainwater from both slopes can run safely down into the gutter.
Why is my roof valley leaking?
Common causes are split or thinning lead, failed laps, slipped tiles along the valley, blocked valleys that overflow, and old linings reaching the end of their life.
How long does a lead roof valley last?
A properly installed lead valley can last for many decades. Problems usually come from incorrect lap lengths, thermal movement splitting the lead, or debris holding water in the valley.
Can a roof valley be repaired rather than replaced?
Yes. Small splits and failed laps can often be repaired. If the lead is thin, cracked along its length or the boards beneath are damaged, replacing the valley is usually the better long-term option.
How long does a valley repair take?
A valley repair usually takes 4–6 hours and a full valley replacement 6–8 hours, so most jobs are completed in one day.
Can you clear a blocked roof valley?
Yes. We clear leaves, moss and debris from valleys and gutters so water drains properly, and check the lining for damage while we are on the roof.
Do you offer free valley assessments?
Yes. Valley assessments and quotes are free, with photos of the problem and no upfront fees.
