Lead Work in Winchester

Lead work is the most frequently misrepaired element of the Winchester housing stock. Silicone sealant over a failed flashing, self-adhesive lead tape, torch-on felt patches — we see all of these on properties across the city, and all of them fail within a few years. Correct lead work, installed to the Lead Sheet Association specification using the right lead code for the application, should last 50-80 years. We install it correctly the first time.

Winchester's Victorian and Edwardian housing has a particularly high lead work density. Chimney stacks with apron flashings, back gutters, soakers and step flashings are standard on Hyde and St Giles Hill terraces. Original Victorian leadwork from the 1890s-1910s is now at or approaching century-mark age — where the original installation used correct-weight lead and proper detailing, much of it is still sound. Where it has been bodged at some point, the failure pattern is usually more extensive than it first appears.

Chimney Lead Work in Winchester

Chimney flashings are the most common lead job across Winchester. A properly detailed chimney uses four distinct lead components: the front apron, two sets of stepped side flashings with soakers, and the back gutter. We replace all four where required, or individual components where the others are sound. On conservation-area properties near the Cathedral Close, we follow the Lead Sheet Association detailing that is appropriate to the building's listing status.

Valley Lead Work in Winchester

Lead valleys are found on most Winchester properties with M-shaped or double-pitched roofing — common on Edwardian villas and 1930s detached houses across Weeke, Harestock and the inner suburbs. A lead valley carries a significant volume of water off two roof pitches into a single gutter or outlet. Where the valley lead fails — typically from a split at a bay joint or a roll that has pulled away from the tilt fillet — water enters the structure at the lowest point of the roof and tracks well away from the failure before appearing internally.

Bay Roof Lead Work in Winchester

Bay windows with flat or shallow-pitched lead roofs are common on Winchester's Victorian and Edwardian stock in Hyde, St Giles Hill and the Cathedral Close area. These small lead roofs are often the first to fail on period properties — they have high water catchment relative to their area, and the flat sections accumulate leaf debris that holds moisture against the lead surface. We replace bay roof lead as a standalone job, and check the gutter outlets and outlet boxes as part of the work.
