Roof Valley Repairs and Replacements in Brighton
Bespoke Roofing provides professional roof valley repairs and replacements throughout Brighton and Hove. We repair leaking, damaged and deteriorated valleys on tiled and slate roofs, including traditional lead valleys, GRP fibreglass valleys and tiled valley systems.
A failed roof valley can allow a significant amount of rainwater into your property because it carries water from two adjoining roof slopes. If you have noticed damp patches, staining, displaced tiles or water entering during heavy rain, call our Brighton roofing team on 01273 447495 for advice and a free quotation.

What is a roof valley?
A roof valley is the channel formed where two sections of a pitched roof meet. Its purpose is to collect rainwater from both slopes and direct it safely towards the gutter.
Because valleys handle large volumes of water, even a small defect can result in a persistent roof leak. Common causes include cracked mortar, damaged lead, split GRP, blocked channels, incorrectly cut tiles and deteriorated roofing membrane beneath the valley.
Our wider Brighton roof repair service covers valley leaks alongside damaged tiles, storm damage, ridge repairs and other common pitched-roof problems.
Signs that your roof valley may need attention
Arrange an inspection if you notice:
Water marks or damp patches beneath a roof junction
Leaks that become worse during heavy or wind-driven rain
Cracked, slipped or missing tiles beside the valley
Split, lifted or badly weathered leadwork
Crumbling mortar along the edges of the valley
Debris or moss preventing water from draining
Sagging or visible deterioration in the valley lining
Previous sealant repairs that have started to fail
The point where water appears inside a property is not always directly below the defect. We inspect the surrounding tiles, valley lining, roof membrane, battens and adjoining roof details to identify the likely source before recommending work.
Lead, GRP and tiled roof valleys
The most suitable valley system depends on the roof covering, pitch, construction and condition of the surrounding area.
Lead valleys
Lead is commonly found on traditional tiled and slate roofs. It is durable when correctly detailed but may eventually split, lift or deteriorate through age and movement. Depending on its condition, we can repair a local defect or replace the affected leadwork.
GRP fibreglass valleys
Preformed GRP valley troughs provide a lightweight, weather-resistant drainage channel. Correct support, alignment and tile detailing are essential to prevent water from escaping beneath the surrounding roof covering.
Tiled valleys
A tiled or close-cut valley creates a neat finish without an exposed central channel. These systems require accurate cutting and secure fixing of the adjoining tiles to maintain an effective drainage path.
We will explain which option is appropriate for your roof rather than recommending one system for every property.
Does the valley need repairing or replacing?
Not every leaking valley requires complete replacement. A local repair may be suitable where the valley lining remains sound and the problem is confined to a small area, such as a damaged tile or isolated mortar failure.
Replacement is more likely to be recommended when the lining is split or extensively deteriorated, the surrounding membrane has failed, previous repairs are no longer effective or the valley has been installed incorrectly.
You will receive a clear explanation of the problem, the proposed work and the materials to be used before the project begins.
Our roof valley replacement process
The precise method depends on the roof, but a typical replacement may include:
Inspecting the valley and surrounding roof covering to identify the extent of the problem.
Providing safe access, including scaffolding where required.
Carefully removing the tiles or slates on either side of the valley.
Removing the defective valley material and checking the exposed battens, membrane and supporting structure.
Replacing deteriorated membrane and treated battens where included within the agreed work.
Installing and correctly detailing the new lead, GRP or tiled valley system.
Cutting, securing and reinstating the surrounding tiles or slates.
Clearing debris and checking that water can drain freely towards the gutter.
Providing photographs of the completed work where practical.
If access is difficult, our drone roof survey service may help us assess visible damage before deciding what access is needed.
Roof valley repairs for Brighton properties
Brighton’s exposed coastal location can place pitched roofs under considerable pressure from strong winds and wind-driven rain. Older tiled and slate roofs may also contain valleys that have already undergone several local repairs.
We work on properties across Brighton and Hove, including Kemptown, Hanover, Preston Park, Patcham, Portslade, Rottingdean and surrounding areas. Our team understands the roof details found on Brighton’s Victorian terraces, period properties, extensions and modern homes.

Roof valley repair FAQs
Can a leaking roof valley be repaired?
Yes, if the damage is localised and the remaining valley system is sound. If the lining, membrane or surrounding roof covering has deteriorated extensively, replacement may be more reliable.
What causes a roof valley to leak?
Common causes include split lead, damaged GRP, failed mortar, slipped tiles, blocked drainage channels, defective membrane and poor installation.
Can you inspect a valley using a drone?
A drone can help identify visible damage on roofs that are difficult to inspect from ground level. A closer physical inspection may still be required before the final repair method can be confirmed.
Do you replace the membrane around the valley?
Where necessary and included in the quotation, we remove the surrounding tiles and replace deteriorated roofing membrane and battens around the affected area.
Do you cover Brighton and Hove?
Yes. We repair and replace roof valleys throughout Brighton, Hove and nearby areas. Call 01273 447495 to discuss your roof.
