A new roof is not a purchase most homeowners make more than once. When the time comes — whether driven by a RICS survey, widespread tile failure, or a roof that has simply reached the end of its life — most people have very little idea of what it should cost, which makes it easy to pay significantly more or less than you should.
This guide gives you the numbers to walk into any contractor conversation informed. Not just the headline figures, but what drives the difference between a £5,000 and a £9,000 quote on the same semi-detached — and exactly what questions to ask before committing to anything.
New Roof Cost by House Type: 2026 Price Tables
The biggest driver of new roof cost is roof area — and roof area broadly corresponds to house type. The tables below assume concrete interlocking tiles (the most common and most affordable option) and include all labour, materials, scaffolding, felt underlay, battens, ridge and hip tiles, and skip hire.
Concrete interlocking tiles — full new roof cost
| Property type | Approx. roof area | Low estimate | High estimate | Duration |
|---|---|---|---|---|
| Mid-terraced house | 40–50m² | £3,500 | £6,000 | 3–5 days |
| End-terraced house | 45–60m² | £4,000 | £7,000 | 4–6 days |
| Semi-detached — 2 bed | 55–65m² | £4,500 | £7,500 | 4–6 days |
| Semi-detached — 3 bed | 65–80m² | £5,000 | £9,000 | 5–7 days |
| Detached — 3 bed | 80–110m² | £7,000 | £12,000 | 6–9 days |
| Detached — 4 bed | 100–130m² | £9,000 | £14,000 | 7–10 days |
| Detached — 5 bed / large | 130–180m² | £12,000 | £18,000 | 8–14 days |
| Bungalow — 2 bed | 50–65m² | £4,000 | £7,000 | 4–6 days |
| Bungalow — 3 bed | 65–85m² | £5,500 | £8,500 | 5–8 days |
* All figures include scaffolding, stripping, new felt (breathable membrane), new treated battens, concrete interlocking tiles, ridge and hip work, and skip hire. These are 2026 national mid-range figures. London and South East add 20–35%.
Clay tiles — full new roof cost
| Property type | Low estimate | High estimate | Premium over concrete |
|---|---|---|---|
| Mid-terraced house | £5,000 | £8,500 | +35% to +45% |
| Semi-detached — 3 bed | £6,500 | £12,000 | +30% to +40% |
| Detached — 3 bed | £9,500 | £16,000 | +30% to +40% |
| Detached — 4–5 bed | £14,000 | £24,000 | +35% to +50% |
| Bungalow — 3 bed | £7,500 | £11,500 | +30% to +40% |
* Clay plain tiles require more tiles per m² than interlocking concrete tiles and take significantly longer to lay. This drives the premium above materials alone. Clay tiles are typically specified for period properties (Victorian, Edwardian, 1920s–30s), conservation areas, and where planning requires matching the existing material.
Natural slate — full new roof cost
| Property type | Spanish slate | Welsh slate | Expected lifespan |
|---|---|---|---|
| Mid-terraced house | £6,000 – £10,000 | £8,000 – £14,000 | 75–150+ years |
| Semi-detached — 3 bed | £8,500 – £14,000 | £12,000 – £20,000 | 75–150+ years |
| Detached — 3 bed | £13,000 – £20,000 | £18,000 – £30,000 | 75–150+ years |
| Detached — 4–5 bed | £18,000 – £28,000 | £26,000 – £45,000 | 75–150+ years |
| Bungalow — 3 bed | £9,000 – £14,000 | £13,000 – £20,000 | 75–150+ years |
* Welsh slate is the premium UK option — it is quarried domestically, considered the most beautiful, and can genuinely last over a century. Spanish slate is imported and costs 30–40% less but is still far more durable than concrete tiles. Reclaimed Welsh slate from salvage yards costs less than new but requires careful sourcing and matching.

What Is Included in a Full New Roof?
A complete roof replacement is not just "new tiles on top." Understanding every element prevents nasty surprises when additional work is found once the old roof is stripped.
| Element | What it is | Included in quote? |
|---|---|---|
| Strip and dispose | Removing all existing tiles, battens, and felt. Skip hire for waste. | Should always be included |
| Timber inspection | Checking rafters and purlins for rot or damage once stripped. | Inspection free — repairs extra (£300–£2,000 if needed) |
| Felt underlay | Secondary waterproof layer beneath tiles. Standard bitumen or breathable membrane. | Should be included — confirm grade |
| Battens | Treated timber strips the tiles are nailed to. Must be BS5534-compliant. | Should always be included |
| Tiles | The roof covering itself. Confirm brand, type, and manufacturer warranty. | Always included — but verify specification |
| Ridge tiles | Tiles along the roof peak. Bedded in mortar or fitted with a dry-ridge system. | Should be included — confirm mortar or dry-ridge |
| Hip tiles | Tiles along sloping external corners (if your roof has hips). | Should be included if hips present |
| Valley linings | Lead or GRP linings at internal roof junctions (if valleys present). | Should be included if valleys present |
| Flashing | Lead flashing at chimneys, dormers, and abutments. Often a separate line item. | Confirm — sometimes quoted separately |
| Scaffolding | Access structure. A legal requirement for full roof replacement. | Often included but always confirm |
| Skip hire | Removal of old tile waste. A full roof strip generates 2–4 tonnes of debris. | Often included — confirm if not |

Roof complexity
A simple gable-end roof — two flat rectangular slopes meeting at a central ridge — is the cheapest to replace. Every additional feature increases cost significantly:
- Hips: Each sloping external corner adds 8–15% to the cost — more cutting, more hip tiles, more labour.
- Valleys: Internal junctions require lead or GRP lining and careful tile cutting — add £200–£600 per valley.
- Dormers: Each dormer window adds complexity around flashing, abutment tiles, and weathering details — add £300–£800 per dormer.
- Chimney stacks: Full lead flashing for a chimney during a re-roof typically adds £400–£900 per stack.
- Flat roof sections: Where the main roof meets a flat section (common on rear extensions), a separate flat roof specification is needed alongside the pitched work.
Felt specification
The felt underlay beneath the tiles is replaced as standard during a full re-roof. The two main options are standard bitumen felt (BS747 1F — the baseline, lifespan 25–35 years) and breathable membrane (various — lifespan 40–50+ years, reduces condensation risk in the loft). The upgrade typically adds £150–£400 on a semi-detached and is worth specifying given the tiles will not come off again for 40–50 years.
Dry-ridge vs mortar ridge
Traditional ridge tiles are bedded in mortar. Mortar eventually cracks and needs repointing every 20–40 years. A dry-ridge system uses mechanically fixed clips — no mortar, maintenance-free, 40–50 year lifespan. The upgrade costs £400–£900 on a standard semi-detached and is strongly recommended on a full re-roof since the ridge is already being rebuilt from scratch.
Access and scaffolding
Full scaffolding is non-negotiable for a roof replacement — any contractor offering to re-roof without scaffold is working outside the Working at Height Regulations. Cost depends on property size and access: £1,000–£1,800 for a semi-detached, £1,500–£2,500 for a larger detached. Most contractors include scaffold in their all-in price — always confirm this in writing before accepting any quote.

Do You Actually Need a New Roof?
A full roof replacement is the biggest single roofing spend a homeowner faces. Before committing, it is worth confirming that it is genuinely needed rather than a series of targeted repairs that would achieve the same result at a fraction of the cost.
✓ Full replacement is right when...
- The felt underlay has failed — sagging, brittle, or split across multiple areas
- Tiles are failing in volume due to frost damage or age — not isolated breakages
- The roof is 50+ years old and has never been replaced
- Timber inspection reveals widespread rot requiring structural work
- A RICS surveyor has specifically recommended full replacement
- Repair costs quoted exceed 60% of full replacement cost
- The roof is concrete tiles from the 1960s–70s — many of these are now spalling and cannot be repaired
✗ Repairs are the right call when...
- Only isolated tiles are broken, slipped, or missing
- Ridge or hip pointing has failed but tiles are in good condition
- Flashing has failed but the roof itself is sound
- The roof is under 30 years old and in generally good condition
- A roofer is recommending replacement on a cold-call inspection
- The felt is intact and the loft is dry — no internal water damage
Planning Permission for a New Roof
In most cases, replacing a roof with the same or equivalent materials does not require planning permission in England and Wales under permitted development rights. However, you do need to check the following before starting:
- Conservation areas: Changing roof materials (e.g. from slate to concrete tiles) or appearance typically requires planning permission in a conservation area. Replacing like-for-like usually does not.
- Listed buildings: Listed building consent is required for any alteration to a listed building, including roof replacement. You must use materials approved by the local conservation officer — often original Welsh or local slate.
- Scotland: Permitted development rules differ from England and Wales. Check with your local planning authority before starting any work in Scotland.
- Article 4 Directions: Some local authorities have Article 4 Directions that remove certain permitted development rights from residential properties — including roof material changes. Check with your local planning department.
How to Get a Fair Quote for a New Roof
A new roof is one of the highest-value domestic jobs a homeowner commissions. The spread between the cheapest and most expensive legitimate quote is often £2,000–£5,000 on the same property. Getting three quotes and knowing what to compare is the single most important thing you can do to protect yourself.
Questions to ask every roofer who quotes
- What tile specification are you quoting? (Brand, type, colour, and manufacturer guarantee)
- Is felt included — and is it standard bitumen or breathable membrane?
- Is scaffolding included in the price, or quoted separately?
- Is skip hire included?
- What batten specification are you using? (Should be BS5534-compliant treated timber)
- Is the ridge system mortar or dry-ridge?
- What workmanship guarantee do you offer, and is it in writing?
- Will you inspect the timber structure once stripped and report before proceeding?
- What is the tile manufacturer's product guarantee?
- Are you NFRC registered? Can I see your public liability insurance certificate?
Payment structure for a new roof
A fair payment structure for a full re-roof: 10–20% deposit on signing, a stage payment of 30–40% once scaffolding is erected and stripping begins, and the balance on satisfactory completion. Never pay more than 50% before any tiles are laid. A contractor who demands the full payment before starting has no incentive to finish the job properly or at all.
