Replacing a roof is one of the largest single spends a Llandudno homeowner faces, and the quotes you receive can vary widely. This 2026 guide sets out real North Wales price bands, what drives cost up and down, and exactly what a complete quote should itemise — so you can judge value rather than just headline price.
What Does a New Roof Cost in Llandudno in 2026?
Roofing is priced per square metre of roof area, then adjusted for pitch, access and detailing. In North Wales — which sits at or slightly below the UK baseline — the 2026 supply-and-fit rates we see are:
| Covering | Cost per m² (fitted) | 3-bed semi (approx) | Lifespan |
|---|---|---|---|
| Concrete interlocking tile | £85–£140 | £5,000–£9,000 | 40–60 yrs |
| Clay plain tile | £110–£210 | £7,500–£13,000 | 60–80 yrs |
| Reclaimed Welsh slate | £150–£280 | £9,000–£16,000 | 80–120 yrs |
| Fibre-cement slate | £110–£170 | £7,000–£11,000 | 50–60 yrs |
These figures are supplied and fitted, including strip-off, disposal, new breathable membrane, new treated battens to BS 5534, ridge work and the new covering. Scaffolding is usually itemised separately at £900–£2,500 for a standard Llandudno semi.
Key fact: A like-for-like roof covering replacement is classed as permitted development and does not normally require planning permission, though conservation-area and material-change rules can alter this. Source: UK Government Planning Portal (permitted development, 2026)
Why Welsh Slate Costs More in Llandudno
Llandudno's Victorian and Edwardian housing stock was originally roofed in Penrhyn Blue Welsh slate, and properties within the Conwy County Borough Council conservation area are generally expected to keep matching materials on visible slopes. Reclaimed Welsh slate carries a material premium over concrete tile, but correctly re-laid with new copper or stainless fixings it lasts three to four times as long — which is why, on a period property held long-term, slate is often the more economic choice across a 100-year horizon.
What Moves the Price on a Llandudno Roof
- Roof size and pitch — steeper and larger roofs cost more in both material and labour.
- Chimney stacks — each stack adds £350–£900 in lead flashing and repointing.
- Scaffold access — three-storey promenade terraces and tight town-centre yards cost more to scaffold.
- Coastal exposure — exposed properties need mechanically fixed ridges, not mortar-only, adding a little to cost.
- Hidden timber — rotten rafter feet or deck boards found on strip-off are priced separately but must be fixed.
What a Complete Quote Should Include
A quote you can trust itemises: scaffold, strip-off and disposal, breathable membrane (specified by grade), treated battens to BS 5534, the new covering (with manufacturer and grade), ridge and verge detail, all lead flashings, and a written workmanship guarantee of at least 10 years. If any of these is missing, ask before you sign.
