Lead work is one of the most demanding parts of roofing and one of the most common sources of leaks when it's done poorly. We carry out lead flashing, valley, and soaker work on properties across Wells-next-the-Sea, from replacing failed mastic repairs on chimney stacks to fitting new valleys on Norfolk pantile roofs.

Lead work covers all the junctions where a roof meets a vertical surface or changes direction — around chimney stacks, dormer cheeks, parapet walls, bay windows, and in valleys between roof pitches. These junctions are the points most likely to leak, and they're the points most often bodged with silicone or mortar by unqualified contractors. We carry out proper leadwork to BS EN 12588 standards using code 3 to code 5 lead sheet depending on the application.
The work involves cutting and dressing lead sheet to fit the profile of the roof covering and the masonry. Flashings are wedged and pointed into mortar joints rather than surface-fixed with adhesive, which is the only method that holds long-term. On Norfolk pantile roofs — common throughout the Wells-next-the-Sea area — the irregular surface profile means valley lead has to be carefully dressed to avoid lifting at the edges. We solder internal angles and upstands where needed and allow for thermal movement with correct step and code specifications.
Silicone and lap sealants fail within a few years in exposed coastal conditions and leave you with the same leak plus a harder surface to work on. Correct lead work, properly fixed, will outlast the rest of the roof — well-laid lead flashings routinely last 50 to 70 years with minimal maintenance.
We'll tell you on the survey whether a flashing can be re-dressed and re-pointed or whether it needs full replacement. Small repairs can often be done in a single visit; chimney stack re-leading typically takes one to two days. All our lead work comes with a ten-year workmanship guarantee.
Lead flashing replacement around a standard chimney stack in Wells-next-the-Sea typically costs between £350 and £700, depending on the stack size and the condition of the surrounding roof covering.
