New Roof Cost UK 2026: £5,500-20,000 for a Full Roof Replacement by Size and Material
Quick Answer
A full roof replacement for a 3-bed semi in the UK costs £5,500-9,500 in 2026 for concrete tiles, or £8,000-14,000 for natural slate. A 4-bed detached costs £9,000-15,000 for tiles and £13,000-22,000 for slate. London and the South East add 25-35% to these figures.
What does a new roof cost in the UK in 2026?
A full roof replacement is one of the largest single spending decisions most homeowners ever face, and getting an accurate picture of the cost before you start calling roofers can save you a considerable amount of money and stress. In 2026, the cost of a new roof in the UK ranges from around £4,500 for a modest 2-bed terraced house with concrete tiles, up to £22,000 or more for a large detached property finished in natural Welsh slate. The gap between those two figures is driven by four main things: the size of the roof, the material chosen, the complexity of the roof structure, and where in the country the property sits.
This guide covers supply-and-fix costs for a complete re-roof, meaning the old tiles are stripped, the felt and battens are replaced, and new tiles or slate are fixed to the roof. It is not a guide to minor repairs. If you only need a handful of tiles replaced or some repointing work on the ridge, the costs are significantly lower and a repair is almost certainly the right call. The guide is useful both for homeowners trying to budget for an upcoming re-roof and for roofers who want a reference point when putting together quotes for their customers.
It is worth understanding from the outset that roofing quotes vary quite widely even within the same area and for the same property. Two roofers can look at the same roof and come in at noticeably different prices, depending on whether they are calculating labour and materials separately or bundling everything into a single supply-and-fix price, how they price scaffolding, and whether they are accounting for any remedial timber work to the roof structure. For this reason, getting at least three quotes before committing is strongly recommended, and this guide will help you understand what should and should not be in each quote. You can also use our roof replacement cost calculator to get a tailored estimate for your property.
New roof cost by property size: 2026 price guide
The table below shows typical supply-and-fix costs for a full roof replacement across common UK property types. Figures assume a straightforward pitched roof with no major structural issues and include scaffolding, stripping the old roof, new felt and battens, and all ridge and hip tiles.
| Property type | Concrete tiles | Natural slate |
|---|---|---|
| 2-bed terraced | £4,500-7,000 | £7,000-11,000 |
| 3-bed semi | £5,500-9,500 | £8,000-14,000 |
| 4-bed detached | £9,000-15,000 | £13,000-22,000 |
| Bungalow | £6,000-12,000 | £9,000-18,000 |
Note: bungalows have a proportionally larger roof area relative to floor area, which is why the cost often exceeds that of a 3-bed semi. London and South East properties should add 25-35% to the figures above.
Roofing cost per m2 in the UK
If you know the approximate area of your roof, you can use a cost per square metre to cross-check any quotes you receive. In 2026, typical supply-and-fix rates per m2 of roof area are as follows.
- Concrete tiles: £45-75 per m2 supply and fix
- Clay tiles: £55-90 per m2 supply and fix
- Artificial slate (fibre cement): £55-85 per m2 supply and fix
- Natural Welsh slate: £85-150 per m2 supply and fix
- Flat roof EPDM rubber: £40-75 per m2 supply and fix
To estimate your roof area, measure the footprint of your house and multiply by a pitch factor. A standard 35-degree pitch adds approximately 20% over the floor area; a steeper 45-degree pitch adds around 40%. So a 3-bed semi with a 60m2 footprint and a standard pitch has a roof area of roughly 72m2. At £50-65/m2 for concrete tiles, that works out to £3,600-4,700 in materials and labour before scaffolding, ridge tiles, and flashing work are added. You can also use our roofing estimate calculator to run through the figures for your specific property.
What is included in a full roof replacement quote?
A properly scoped supply-and-fix re-roof quote should include the following items. If any of these are missing, ask the roofer to clarify whether they are included or whether they will be quoted separately.
- Stripping and disposing of existing tiles
- New roofing felt or breathable membrane underlay
- New timber battens
- New tiles or slate to cover the full roof area
- Ridge, hip and valley tiles or lead
- Lead flashing around chimneys, abutments and roof windows
- Guttering if required (confirm whether this is included)
- Scaffolding erection and dismantling
What is not usually included?
Some items are typically quoted separately or may only become apparent once work is underway. Budget for these as contingencies if there is any doubt.
- Chimney repairs or repointing (usually a separate cost, £500-2,500 depending on condition)
- Structural repairs to rafters or joists if they are found to be rotten or damaged when the tiles come off
- Fascia, soffit and bargeboards: add £1,500-3,500 to replace the full house in uPVC
It is reasonable to ask your roofer to include a provisional sum for contingencies in the quote. Most experienced roofers will flag that the condition of the timbers cannot be fully assessed until the tiles are removed, and a provisional allowance of £500-1,500 for remedial timber work is not unusual on an older property.
Key factors that affect the cost of a new roof
The headline price range for a re-roof is wide for a good reason. Several variables can push the final cost significantly higher or lower than the midpoint figures shown in the table above. Here is what matters most.
1. Roof area (m2)
The single biggest driver of cost. A larger roof requires more materials and more labour days. Bungalows catch many homeowners out here: they have a much larger roof-to-floor ratio than a two-storey house of equivalent bedroom count, which is why they often cost as much as a 4-bed semi to re-roof.
2. Material choice
Concrete tiles are the most affordable option and account for the majority of re-roofs in the UK. Clay tiles cost more but last considerably longer and are required on many period properties to maintain character. Natural Welsh or Spanish slate is the premium option and can more than double the material cost compared with concrete tiles. Artificial fibre cement slate offers a middle ground, giving a slate appearance at a lower price point.
3. Pitch and complexity
A simple gable roof with two planes is the easiest and cheapest to tile. Hipped roofs, roofs with valleys, dormers, skylights, and multiple chimney stacks all add cost. Each hip, valley and penetration requires additional cutting and flashing work, which takes time and uses more material. A complex hipped roof on a 4-bed detached can cost 15-30% more than the same house with a simple gable end.
4. Scaffolding
Scaffolding is non-negotiable for a full re-roof and typically costs £800-1,500 for a 3-bed semi. This is usually built into the quote, but always confirm. Scaffolding on a corner plot or where a neighbour's garden needs to be accessed can add to the base cost. The scaffold typically stays in place for 1-2 weeks on a standard re-roof.
5. Condition of the roof structure
If the rafters, purlins or ridge board are in poor condition, remedial timber work will add to the bill. This is particularly common on Victorian and Edwardian properties where the original timbers have had 100 or more years of weather and moisture exposure. A roofer cannot always see the full extent of any damage until the existing tiles are stripped.
6. Location: London and South East premium
Labour rates in London and the South East are significantly higher than the national average. This is partly a reflection of higher living costs and partly a function of strong demand. Expect to add 25-35% to the figures in the cost table if you are in London, and 15-20% if you are in the wider South East.
Regional price variation across the UK
Roofing costs vary considerably across the UK, and understanding the regional picture will help you judge whether a quote is reasonable for your area. The national average figures in this guide reflect a blended picture, and the adjustments below will help you calibrate them for your location.
| Region | Adjustment vs national average |
|---|---|
| London | +25% to +35% |
| South East | +15% to +20% |
| South West, East of England | Broadly in line with national average |
| Midlands, Yorkshire | -5% to +5% |
| North West, North East | -5% to -10% |
| Scotland | -5% to -10% |
| Wales | -5% to -10% |
| Northern Ireland | -10% to -15% |
One interesting exception in the regions is natural slate in Wales. Because Welsh slate quarries are local to parts of Wales and the North West, the material cost can be somewhat lower than in the South East, narrowing the price gap between tile and slate options in those areas.

How to get an accurate quote for a new roof
Getting three quotes from local, reputable roofers is the single most effective thing you can do to ensure you are paying a fair price. But the quality of the quotes matters as much as the number. Here are some practical steps that will help you get meaningful, comparable figures.
Ask for a written, itemised quote
A verbal ballpark is not a quote. Ask for a written breakdown that separates materials from labour, specifies the material brand and type, and states whether scaffolding and waste disposal are included. This makes comparison between roofers straightforward and avoids disputes when the work is underway.
Check insurance and trade membership
Any roofer working on your property should hold current public liability insurance, ideally with at least £2 million cover. Ask to see the certificate. Membership of a trade body such as the NFRC (National Federation of Roofing Contractors) or the Competent Roofer scheme is a useful indicator of professionalism, though it is not universal among good independent tradesmen.
Ask about the underlay and battens
On a full re-roof, a good roofer will replace the felt underlay and the timber battens as a matter of course. Some cheaper quotes may propose to reuse existing battens to save cost. This is a false economy: the battens will be at least as old as the tiles being removed and will likely be nearing the end of their serviceable life.
Agree a payment schedule
A reasonable payment structure for a re-roof is a deposit of around 20-30% to cover materials, a stage payment when the scaffold is up and the old tiles are stripped (say 40%), and the balance on completion. Never pay more than 50% upfront, and avoid any contractor who asks for the full amount before starting work.
Consider timing
Spring and early summer tend to be the busiest time for roofers in the UK. Booking work for autumn or winter, when demand is lower, can sometimes result in a more competitive quote. That said, roofing in wet or icy conditions carries its own risks, and a reputable roofer will not tile in frost or heavy rain regardless of scheduling.
Frequently asked questions
How often does a roof need replacing?
Concrete tile roofs last 30-50 years. Natural slate roofs can last 80-100 years if the structure is sound. Clay tiles last 60-80 years. Flat EPDM rubber roofs last 20-30 years. Most roofs need a full replacement once during the lifetime of a typical owner. Signs that replacement is due include widespread cracked or slipped tiles, persistent leaks, sagging rafters, and moss or vegetation growth across more than 20% of the surface. If your roof is over 40 years old and you are experiencing recurring problems, a full replacement is likely to be more cost-effective than continued piecemeal repairs.
Is it cheaper to repair or replace a roof?
Repairs are always cheaper in the short term. Replacing 10-20 tiles, repointing a ridge, or resealing flashing costs £300-1,500. However, if more than 20-30% of tiles need replacing, or if the underlay (felt) has failed, a full re-roof usually makes more economic sense. An old, degraded underlay will allow moisture into the roof space even if the tiles themselves appear sound, leading to condensation problems and eventual timber damage. A roofer can inspect and advise. Ask for an honest assessment of the remaining life of the existing materials before committing to repair costs that may only delay the inevitable.
What is the cheapest roofing material in the UK?
Concrete tiles are the most cost-effective roofing material, typically £12-18 per m2 for materials. They are widely available, straightforward to lay, and carry a manufacturer guarantee of 30 years or more. Artificial slate tiles (fibre cement) cost slightly more at £15-25/m2 but look better on certain house styles and are accepted in some conservation areas where natural slate was the original material. Natural Welsh slate is the premium option at £40-80/m2 for materials, but it is extremely durable and can last a century with proper maintenance of the underlying structure. Flat roof EPDM is the cheapest option for flat sections at £8-15/m2, with significantly lower labour costs than pitched roof work.
Does scaffolding come with the roofing quote?
Most roofers include scaffolding in their quote, but always confirm this before accepting. Scaffolding for a 3-bed semi costs £800-1,500 and typically needs to stay in place for 1-2 weeks. For very small repair jobs, some roofers use a man-safe roof hook and do not need full scaffolding, which reduces cost significantly. On a full re-roof, scaffolding is a safety requirement under the Work at Height Regulations 2005 and should never be omitted to save money. If a quote appears unusually low, check whether scaffolding has been excluded.
Does a new roof need planning permission?
Replacing a roof with the same material and style does not require planning permission in most cases under permitted development rights. However, if you are changing the material, for example from concrete tiles to natural slate, altering the roofline, or if the property is in a conservation area or is listed, you should check with your local planning authority before starting work. Extensions to the roof structure, such as adding a dormer or a roof light that projects above the existing plane, always require planning permission. Getting this wrong can result in an enforcement notice requiring you to reinstate the original roof at your own cost, so it pays to check early.
