How Much Does It Cost to Re-Roof a House in the UK?

Typical re-roofing costs in 2026

For a straightforward pitched roof on a typical three-bed semi, most UK homeowners currently pay somewhere between £6,000 and £12,000 for a full strip and re-roof using concrete tiles. A small terrace might come in at £4,500 to £8,000, while a large detached house with a complex roof can easily reach £15,000 to £25,000 or more. These figures include stripping the old covering, new breathable membrane and battens, the new tiles or slates, and scaffolding.

Material is the biggest single variable. Concrete interlocking tiles are the cheapest option, clay tiles sit in the middle, and natural slate is the most expensive, often adding 40 to 80 per cent to the covering cost compared with concrete. Around Wrexham and the wider North Wales area, many older properties have Welsh slate roofs, and replacing like for like with new natural slate costs considerably more than switching to a man-made slate alternative, though it usually looks better and lasts longer.

• Small terrace, concrete tiles: roughly £4,500 to £8,000
• Three-bed semi, concrete tiles: roughly £6,000 to £12,000
• Three-bed semi, natural slate: roughly £10,000 to £18,000
• Large detached, complex roof: £15,000 to £25,000 plus

What pushes the price up or down

Beyond size and material, the condition of what is underneath matters. If the roofer strips the tiles and finds rotten rafters, failed valleys or crumbling chimney brickwork, that work has to be priced in. A decent contractor will flag known risks in the quote and agree how unforeseen timber repairs will be charged, typically at a day rate plus materials, rather than hiding them in a vague total.

Access and complexity also count. A simple dual-pitch roof on an easy street is quick to scaffold and strip. Dormers, hips, valleys, multiple chimneys, or a terraced house with no rear access all add labour time. Scaffolding alone usually runs £800 to £1,500 for an average semi. Extras such as new fascias, soffits, guttering, dry ridge and verge systems, or upgraded loft insulation are worth doing while the scaffold is up, but each adds to the bill, so ask for them as separate line items.

Re-roof or repair? How to decide

A full re-roof is rarely the first answer. If you have a handful of slipped or cracked tiles and the felt underneath is sound, a repair costing £150 to £600 is the sensible route. Re-roofing becomes worthwhile when failures are widespread: nail fatigue causing slates to slip repeatedly, original underfelt torn and letting in wind-driven rain, or tiles so weathered they crumble when handled. If you are paying for repairs more than once a year, the sums start to favour doing the whole thing properly.

Age is a useful guide. Concrete tile roofs typically last 40 to 60 years, clay and good slate considerably longer, but the felt and fixings under an older roof often fail before the covering does. In North Wales the weather does the roof no favours either, as exposed sites facing the prevailing westerlies take a battering that shortens the life of ridge mortar and flashings in particular.

Getting quotes and avoiding nasty surprises

Get at least two or three itemised written quotes, and check each one covers the same scope: strip and dispose of the old covering, membrane, battens, covering material and fixing specification, ridge and verge detail, flashings, scaffolding, and waste removal. If one quote is dramatically cheaper, something is usually missing, often the scaffolding, the skip, or a proper breathable membrane.

Also ask about guarantees and paperwork. New tiles and slates carry manufacturer warranties, but the workmanship guarantee from the installer matters more, so get it in writing. If your home is in a conservation area or is listed, common in parts of Wrexham and the surrounding villages, check with the local planning authority before changing the roof material, as you may be required to reuse or match the existing slate.
