Roof replacement cost in 2026: prices by house type and material

A new pitched roof costs £4,000 to £20,000 on most UK houses in 2026, and the house type decides where you land: a terrace sits at the bottom and a large detached home runs past the top. We price the job by house type, covering and roof area, with scaffolding on its own line, then cover what the strip-out uncovers, regional prices, timescales and the rules in each UK nation.

Roof replacement cost by house type

These are 2026 prices for stripping and re-covering a pitched roof with a standard tiled covering. They include the scaffolding, taking off the old roof and getting rid of the waste. The top of each range includes VAT at 20%, so ask every roofer whether their figure does.

Terraced house roof replacement cost

A terrace has the smallest roof, usually 40 to 60 m², so it sits at the bottom of the table at £4,000 to £9,000. A Victorian or Edwardian terrace adds £500 to £1,000 to the base price. If the neighbours re-roof at the same time, sharing the scaffold saves £300 to £600.

Semi-detached roof replacement cost

A semi's roof covers 50 to 90 m² and costs £5,500 to £14,000 to replace. Labour makes up 40 to 50% of the bill. The rest is tiles, underlay and battens, scaffold hire and the skip. A hipped semi, with a sloping end instead of a gable wall, has more cutting and more ridge to fix than a gabled one of the same size.

Detached house roof replacement cost

A 3 to 4 bed detached house has 80 to 130 m² of roof and costs £8,000 to £20,000. Detached roofs are more likely to carry hips, valleys, dormers and more than one chimney, and each adds cutting and flashing work. Large or extended detached homes, at 130 m² and up, run £18,000 to £35,000 or more.

Bungalow roof replacement cost

A bungalow's roof is often bigger than a terrace's, at 60 to 110 m², because the whole home sits under it. It still costs £4,500 to £8,000 to replace. The single-storey height keeps the scaffolding and access simple, and that holds the price down.

Scaffolding cost for a new roof

Scaffolding costs £800 to £1,500 for a typical two-storey house, and on a semi it is usually £900 to £1,300 of the total. It goes up before the strip-out and stays until the last ridge tile and flashing are done, so a longer job means a longer hire.

Ask for it as a separate line. A quote that folds the scaffold into one total cannot be compared with one that itemises it, and it hides whether the scaffold reaches the chimney and every slope being re-covered.

What a roof replacement quote includes

A full re-roof quote covers more than tiles and labour. It should price the scaffold, stripping the old covering, new underlay and battens, the tiles or slates, the ridge and hips, lead flashings at walls and chimneys, and taking the waste away. Stripping and disposal alone run £800 to £2,000.

Roofing work on an existing home is standard-rated at 20%, and that includes the materials the roofer supplies, under HMRC's VAT Notice 708. On a £10,000 job that is £2,000, so compare quotes only once you know which ones include it.

Guarantees come in three kinds. A manufacturer's warranty covers the tiles or slates, and a workmanship guarantee covers how they were fitted. An insurance-backed guarantee is underwritten by a third-party insurer, so the cover can continue if the roofer stops trading.

Roof replacement cost by material

After the size of the roof, the covering is the biggest choice. These are fitted prices per m² of roof, with the lifespan each covering usually reaches.

On a 3-bed semi of about 75 m², all-in with VAT, concrete tiles come to £8,500 to £12,000, clay tiles to £10,500 to £16,000 and natural slate to £13,000 to £20,000. Choosing concrete over clay trims 15 to 20% off the materials, and slate buys the longest life for the highest price.

A change of covering is also a structural question. If the new covering is heavier or lighter than the old one, the roof structure may need modifying or strengthening, and a structural engineer or surveyor should check it before work starts.

A flat roof is priced on its own scale. GRP fibreglass costs £70 to £110 per m² fitted and lasts 25 to 30 years, which keeps flat roof replacement costs for an extension or garage well below a pitched re-roof.

What pushes a roof replacement price up

Two roofs of the same area can be thousands of pounds apart. These are the lines that make the difference:

• Pitch and access. A steep roof, or one above a conservatory or a narrow passage, needs more scaffold and slower, safer work.
• Roof shape. Hips, valleys and dormers mean more cutting, more ridge and more flashing, so the type of roof you have moves the price as much as its area.
• The chimney. Re-leading a chimney costs £300 to £800 and repointing it £150 to £500.
• What the strip-out finds. Rot or woodworm in the rafters only shows once the tiles are off, and structural timber repairs add £200 to £1,500.
• Insulation. Upgrading the roof insulation as part of the job adds £400 to £1,200.
• Spray foam. Spray foam insulation on the underside of the roof usually comes off before a re-roof, at £1,500 to £4,000 or more.

Roof replacement costs by region

Where you live moves the price of the same roof by thousands of pounds. These are 2026 prices for a 3-bed semi in concrete tiles, including VAT, across London and the South of England.

A re-roof in outer London tops the table at £12,000 to £20,000 or more for a semi, against a UK-wide semi range that starts at £5,500. Homes on the coast add 5 to 10% for anti-corrosion treatments.

How long a roof replacement takes

Roofers work year-round, so a winter re-roof is normal. The roofer plans each day around the forecast and takes extra precautions in cold or wet spells.

A standard re-roof runs in this order:

1. The scaffold goes up, with a skip or chute for the old covering.
2. The old tiles or slates, battens and underlay come off.
3. The rafters are inspected, and rotten timber is repaired or replaced at the agreed rate.
4. New underlay and battens go on, then the new tiles or slates.
5. The ridge and hips are fixed and the lead flashings at walls and the chimney are renewed.
6. Building regulations sign-off is arranged, the scaffold comes down and the site is cleared.

In a bigger project the roof comes early. Structural repairs, roofing, services and insulation all go in before the finishes, so in a full renovation budget the re-roof is one of the first lines spent.

Planning permission and building regulations for a new roof

Building regulations in England

In England, replacing the roof covering on a pitched or flat roof needs building regulations approval, while most repairs do not. The approval can come by one of two routes.

• Competent person scheme. A roofer registered with a scheme that covers the work self-certifies it and tells the council for you. You receive a certificate within 8 weeks of completion.
• Building control. Otherwise the job goes to the council's building control or a registered approver. On a building notice, work can start 2 days after the notice goes in.

A roof counts as a thermal element, so re-covering it should include improving the insulation. Changing the material, from slate to tiles for example, is likely to need approval so that the structure and fire safety can be checked.

Planning permission in England

Like-for-like re-roofing does not normally need planning permission. A listed building needs listed building consent for any significant work, inside or out. In a conservation area, or where an Article 4 direction removes permitted development rights, ask the council before changing the covering.

Roof replacement rules in Scotland, Wales and Northern Ireland

Scotland issues building warrants instead of building regulations approval. Under Scotland's building standards, replacing an external covering, in whole or in part, with material of the same general type needs no warrant. The work still has to meet the regulations and be no worse than what it replaced. A change of covering type falls outside that exemption, so ask the council's building standards team before swapping slate for concrete tiles.

Wales has its own Approved Documents and its own planning system, so the England rules above do not carry over automatically. Ask the council's building control team before the strip-out starts.

Northern Ireland has separate planning and building control. Check with building control there before work starts, and before any change of covering in particular.

Repair or replace your roof

A repair is the right call while the damage is local: a few slipped tiles, one failed flashing, a single leak. Once more than 25 to 30% of the tiles are damaged, replacement is usually the better long-term spend. The same goes for a covering near the end of the lifespan shown in the materials table.

Patching a roof leak while you gather quotes keeps water out of the ceilings, and an emergency repair to stabilise a roof before the re-roof costs £200 to £800.
