Step flashings, back gutters, valleys, soakers and aprons — all installed in correct code-grade lead to BS EN 12588. Salt air demands quality leadwork. Free surveys across Llandudno and the North Wales coast.
Correct lead specification and installation is the difference between a flashing that lasts 60 years and one that fails in 15. We do it right every time.
Code 4 lead step flashings with individual code 3 soakers, correctly lapped and pointed into mortar joints. The standard that protects Llandudno Victorian chimney stacks from Atlantic weather.

Get a quote →Code 6 lead valley replacement on pitched roofs — stripped to timber, boards checked, new valley correctly overlapped and clipped. The right fix where old mortar fillets or GRP trays have failed.
Get a quote →Wall-to-roof abutment step flashings and cover flashings where extensions and dormer walls meet the main roof. Correctly soakered and pointed.
Get a quote →Code 4 or 5 apron flashings at chimney stack bases and dormer cheeks, correctly dressed to the tile or slate and pointed. Often the first lead to fail on Llandudno north-facing elevations.

"Lead valley had been patch-repaired three times by previous owners. Stripped back to timber, checked the boards, new valley laid correctly. Clean work, right spec."
"Abutment flashing to the extension wall had been leaking since we moved in. Full step flashing replacement in code 4, correctly soakered. Dry on the first test of winter."
Correctly installed code-grade lead should last 60–80 years inland. In Llandudno's coastal salt-air environment, expect 40–60 years — salt oxidation and mortar joint erosion are the main accelerants. Cheaper or incorrectly installed lead can fail in 15–20 years. We use BS EN 12588 code-grade lead on every job.
A standard chimney stack with step flashings, back gutter and apron typically costs £350–£700 to re-flash completely. A roof abutment to a side wall runs £250–£500. Lead valley replacement costs £400–£800 depending on length. Free survey and written quote before any work begins.
Code 4 (1.8mm) for standard step flashings and soakers. Code 5 (2.24mm) for back gutters, wide aprons and any flashing with significant water load. Code 6 for lead valleys and large gutter linings. We specify correctly for each application.
Rarely worth it. Old lead becomes work-hardened and brittle at dressed folds. Attempting to re-dress it typically causes cracking. New lead is the correct approach — the cost difference over the installation's life is negligible.
Yes — lead valley replacement is one of our most requested specialist jobs on Llandudno Victorian and Edwardian stock. We strip the existing valley, check underlying timber, and install a correctly overlapped and clipped lead valley to current standards.
