Valleys
Valleys are one of the most vulnerable parts of the roof. They are the most trafficked by water, they expand and contract in high/low temperatures and are prone to leaking.
Traditionally, these have for years been done in lead or, in rare occasions, tiled. Lead valleys last around 50-60 years depending on the thickness, and should be checked yearly for blockages and any damage following storms.
Leadwork is the most common way to replace valleys and should be done in sections, no more than 1400mm long with overlaps to accommodate expansion and contraction.
Repairs
Temporary repairs can be conducted to valleys using flash band and liquid sealants like Acrypol and Bitumen. They are, however, only very temporary - and, if cracks and leaks in valleys appear, this is often the sign to have them replaced.
Findley's offers lead valley replacement using 18” Code 5 leadwork, priced at £432 per linear meter,
including VAT but not scaffold
