Leadwork fails at the details — splits from thermal movement in over-long sheets, tired flashings at chimneys and valleys, or corrosion where the wrong code was used.
When it is not the answer: If the lead is sound and only the pointing above it has failed, repointing is the fix, not new leadwork. Read the full guide.
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 5 lead back gutters behind chimney stacks and at abutments, correctly laid to falls with expansion clips. The most commonly failed detail on older Llandudno properties.
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.

Call now →Age is not the enemy of good leadwork — correctly-coded lead lasts a century or more — but bad detailing kills it in a decade. The classic failure we see on Llandudno roofs is lead sheets run too long without expansion joints, so thermal movement splits them; or under-coded lead used to save money, which simply cannot survive this coast's wind. When we renew leadwork we size the bays correctly, use the right code for the exposure, and dress and clip it properly for movement, then finish with patination oil to stop the white staining that streaks down walls below new lead.
Leadwork is one of the oldest and most skilled roofing trades, and it rewards doing properly: a well-detailed lead flashing, valley or parapet is effectively a permanent fixture. We treat it as such, which is why we would rather renew a failing lead detail correctly once than patch it repeatedly, and why every piece of leadwork we carry out is backed by our written ten-year workmanship guarantee.
"Full chimney re-flash on our Victorian terrace. Step flashings, back gutter, new apron. All in BS code 5, correctly lapped and pointed. The previous bodge job lasted barely five years — this will outlast us."
"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."
We check codes, joint spacing and fixings to find why the lead has failed.
New flashing, valley or bespoke leadwork priced with the correct lead code specified.
Scaffold to the chimney, parapet or valley for safe leadwork.
Lead cut, bossed and dressed to the correct code, with proper laps and clips for movement.
Patination oil applied to prevent staining, junctions checked, and handed over.
| Job | Typical duration |
|---|---|
| Flashing renewal | Half to full day |
| Valley re-lead | 1–2 days |
| Parapet / box gutter lead | 1–3 days |
| Bespoke leadwork | Quoted per job |
| Chimney lead detail | Half to full day |
Leadwork needs dry conditions for dressing and patination; we schedule around the forecast.
Leadwork almost always needs scaffold for safe standing time at chimneys, valleys and parapets. Scaffold is specified for: all chimney, valley and parapet leadwork above single-storey - always itemised in your written quote, never a hidden extra, and we arrange it.
Victorian and Edwardian terraces around Craig-y-Don and the town centre often mean rear-access scaffold and permit-controlled pavement space near the promenade. Pavement scaffold and skip permits go through Conwy County Borough Council; allow a few working days on streets like Mostyn Street, Madoc Street, Builder Street where space is tight.
| Job | Typical range | Notes |
|---|---|---|
| Lead flashing renewal | £350–£650 | Code 4 |
| Valley re-lead | £600–£1,400 | Code 5, per valley |
| Parapet / box gutter | £800–£2,500 | Depending on length |
| Chimney lead detail | £350–£700 | Apron & soakers |
| Bespoke leadwork | From £500 | Quoted per job |
Worked example: A a valley re-lead on a Victorian terrace off Church Walks worked out around £980 including access and waste removal.
Staged on larger leadwork; smaller flashings on completion. Nothing before materials are on site.
Leadwork is guaranteed for 10 years on workmanship; correctly-coded lead itself lasts a century or more.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Scaffold to the work area and some dressing noise — a clean job with little waste, cleared on completion. You do not need to stay home for external work - we just need power and access agreed in advance.
Lead can be worked in most conditions but patination and some detailing need a dry surface. Salt-laden Irish Sea wind off the Great Orme drives rain into west-facing elevations and speeds corrosion of fixings.
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.
No call-out fees. No obligation. Just an honest quote from a local Llandudno roofer who turns up when they say they will.
