A complete 2025 guide to roof replacement costs across Llandudno, Conwy Bay and the North Wales coast — with real price ranges, what drives costs up and down, and what your quote should include.
A full roof replacement on a standard 3-bed semi-detached in North Wales costs £4,500–£9,000 for concrete interlocking tile, and £7,500–£14,000 for reclaimed Welsh slate. The wide range reflects property size, chimney complexity, scaffold specification and material choice.
Key fact: NFRC guidance recommends a minimum 10-year workmanship guarantee on all domestic re-roofing work, alongside separate manufacturer material guarantees. Source: National Federation of Roofing Contractors (NFRC) guidance

A complete re-roof quote should itemise: scaffold erection and removal, full strip of existing tiles or slate, disposal of old material, new breathable felt, new treated timber battens, new tiles or slate (specifying manufacturer and grade), new ridge tiles, any lead valley or flashing work, and a written workmanship guarantee of at least 10 years.

Correctly installed concrete interlocking tile: 30-50 years. Reclaimed Penrhyn Blue Welsh slate, correctly fixed with copper nails: 80-120 years. The coastal environment reduces these figures by 10-15% versus sheltered inland sites.
Standard home insurance covers damage from insured events (storm, fire, flood) but not general wear and deterioration. If your roof needs replacing due to age and condition, the cost falls to you.
Scaffold is one of the most variable elements in a re-roof quote. On a standard Llandudno two-storey semi-detached, scaffold erection, hire for the project duration, and striking should cost £400–£900. Three-storey Victorian terraces on the promenade run £800–£1,500. If a quote omits scaffold entirely, the contractor either intends to work from ladders — inadequate for a full re-roof — or has hidden the cost elsewhere. A reliable contractor separates scaffold costs in their quote.
The scaffold for a re-roof gives access to fascias, soffits, guttering and chimney stacks. Combining these overdue maintenance items in the same scaffold mobilisation saves £400–£800 versus separate visits. We always survey fascia, soffit and guttering condition as part of every re-roof survey and advise honestly on whether combining makes economic sense for your property.
