What the job involves
A valley is the internal angle where two roof slopes meet and concentrate drainage into a narrow channel. Valleys handle two roof slopes’ worth of water, which makes them the most hydraulically-stressed part of a pitched roof, and they fail earlier than the surrounding covering.
Repair options range from clearing moss and resealing a sound lead valley, through replacing a rotten mortar-bedded valley with new lead or GRP, to rebuilding a valley where the underlayment has perished.
Sheffield — local context
Traditional material: Welsh slate and sandstone stone slate.
Parts of Nether Edge, Broomhall and Ranmoor are conservation areas where original slate or stone slate roofs are protected; the Peak District National Park boundary sits within a short drive and brings AONB-adjacent planning policy into play for western suburbs.
What changes the price
- Length of the valley and access.
- Whether the underlying boards and battens need replacing.
- Material choice — dressed lead, GRP valley trough, or mortar-bedded.
- Scaffold or cherry picker access for longer runs.
Timeline: Usually 1–3 days depending on length and access.

Why do valleys leak more than the rest of the roof?
All the water from two roof slopes concentrates into a narrow channel. Any debris, moss, ice build-up, or slight sag causes water to back up under the tiles either side, which creates a leak in winter rain or snowmelt.
Is a lead valley better than a GRP one?
Lead has a longer service life (80–100 years) if dressed properly, but GRP valley troughs are cheaper and faster to install and have a 30–40 year life. On a re-roof, lead is the traditional choice; on a budget repair, GRP is a legitimate option.
What does valley repair typically cost in Sheffield?

Are there any Sheffield-specific things that affect price?
