A new roof is one of the biggest repair bills a homeowner will face, and the price range is wide. This guide explains what a roof replacement typically costs in the UK in 2026, how the price changes with house size and covering, what is included in a quote, what pushes costs up and how to compare quotes fairly. All figures are general guides based on a range of UK price guides, so treat them as a starting point and get written quotes for your own roof.
How Much Does a New Roof Cost?
As a general guide, a full re-roof on a typical three-bedroom semi-detached home in a standard concrete tile commonly falls somewhere between £6,000 and £11,500, while clay tile and natural slate cost more. A small terraced house can be lower, and a large detached house with a complex roof can run well above £20,000. The covering is the biggest single factor, followed by roof area, access and any structural repairs found once the old roof is stripped.
New Roof Cost by House Type
| House type | Typical roof area | Concrete tile (general guide) | Clay or natural slate (general guide) |
|---|---|---|---|
| Small terraced | Up to about 40 m² | About £4,500 to £8,000 | About £6,500 to £11,000 |
| 3-bed semi-detached | About 55 to 80 m² | About £6,000 to £11,500 | About £9,000 to £18,500 |
| 3 to 4-bed detached | About 70 to 110 m² | About £7,500 to £15,000 | About £11,000 to £22,000 |
| Large or complex roof | 120 m² or more | From about £12,000 | From about £16,000, often much higher |
These ranges generally assume a like for like replacement with scaffolding, stripping and disposal of the old covering, new membrane and battens, and ridge tiles. Hips, valleys, dormers and chimneys push the cost higher.
Cost by Roof Covering
| Covering | Relative cost | Typical lifespan |
|---|---|---|
| Concrete tiles | Lowest of the main pitched coverings | 40 to 60 years |
| Clay tiles | Mid to high | 60 to 100 years |
| Natural slate | Highest of the common coverings | 80 to 100+ years |
| Single ply flat roof | Varies with size and detail | 25 to 35 years |
| EPDM flat roof | Moderate on small roofs | 30 to 50 years |
For more detail on materials, see our guides to roof tile prices, clay roof tiles and the slate roof guide. Natural slate often costs more than double a concrete tile roof upfront, but its long lifespan can make it good value per year.

Flat Roof Replacement Costs
Flat roofs are priced differently, because they are usually smaller and cost more per square metre. As a general guide, a garage flat roof of 15 to 25 m² typically costs about £1,200 to £3,500, depending on the covering, the deck condition and access. A larger single-storey extension is typically several thousand pounds. Our flat roof materials guide compares the options.
What a Quote Should Include
- Scaffolding, which on a typical semi is often in the region of £1,000 and more on larger or awkward houses.
- Stripping and disposal of the old roof covering and waste.
- New breathable membrane or felt, battens and fixings.
- The new tiles or slates, plus ridge, hip and verge fittings.
- Flashings, valleys and any lead work.
- Labour, which commonly makes up around 40 to 50 percent of the total.
- VAT, if the contractor is VAT registered.
- Any guarantee or warranty terms.
What Affects the Price?
- Roof size and complexity. Hips, valleys, dormers and chimneys add labour and materials.
- Covering. Slate and clay cost more than concrete, and some older roofs need strengthening to carry heavier materials.
- Access and pitch. Steep roofs and awkward access need more scaffolding and time.
- Hidden damage. Rotten battens, rafters or wall plates are often found once the covering is stripped.
- Insulation and ventilation. Building regulations may require better insulation when a roof is substantially renewed.
- Roofline work. Fascias, soffits, gutters and lead flashings are often replaced at the same time.
- Asbestos. Some older roofs contain asbestos cement sheets or slates, which need specialist removal and disposal.
Regional Price Differences
Labour rates vary across the UK. As a rough guide, London and the South East are typically 15 to 25 percent above the national average, the Midlands and North West sit closest to it, and the North East, Scotland and Wales are often 10 to 15 percent below. Local demand and the time of year also affect prices.
Repair or Replace?
A full replacement is not always necessary. As a general rule, if repair costs are close to 30 to 40 percent of the cost of a re-roof, or the roof is well beyond most of its expected lifespan, replacement usually offers better long term value. If your problem is a single leak, start with our guide to roof leak repair cost and the broader roof repair guide. Our article on how long a roof lasts helps you judge where your roof is in its life.
How Long Does a New Roof Take?
A typical re-roof on a semi-detached house usually takes around 3 to 10 working days, depending on size, weather and complexity. Larger detached houses and roofs with many details can take two to three weeks.
Planning, Regulations and Safety
A like for like roof replacement normally does not need planning permission in England. Changing the roof shape or height, adding dormers or altering a listed building or a property in a conservation area usually does. Building regulations may apply to insulation, ventilation and structural changes. Scotland, Wales and Northern Ireland have their own rules, so check locally.
Working at height is dangerous. A new roof should be fitted using proper scaffolding and by experienced roofers, not as a DIY job.
Asbestos warning. Older roofs may include asbestos cement sheets, slates, soffits or flue pipes. Do not disturb or break these, and get a competent surveyor to identify them before work begins.
How to Compare Quotes
Get at least three written, itemised quotes and compare like with like, since a cheaper headline price can hide missing items such as scaffolding or waste removal. Ask about insurance, guarantees, payment terms and who will be on site. Checking whether a roofer belongs to a trade body such as the National Federation of Roofing Contractors can help, but always ask to see proof of insurance and recent work too. Be cautious of door-to-door callers, large upfront payments and pressure to decide quickly.
Ways to Manage the Cost
- Compare several quotes with the same specification.
- Book non-urgent work for quieter months, when some roofers offer lower prices.
- Do roofline work such as fascias, soffits and gutters at the same time to avoid paying for scaffolding twice.
- Ask whether sound existing timber can be reused where safe to do so.
- Check whether your home insurance covers storm damage.
Frequently Asked Questions
How much does a new roof cost for a semi-detached house?
As a general guide, about £6,000 to £11,500 in concrete tile, and more for clay or natural slate, depending on size, access and region.
How much is scaffolding for a new roof?
On a typical three-bedroom semi it is often in the region of £1,000, and more for larger or awkward properties. It should be itemised on your quote.
Is a new roof cheaper in winter?
Some roofers offer lower prices in quieter months, but weather can delay work, so ask about timing and how they protect an open roof.
Do I need planning permission for a new roof?
A like for like replacement usually does not. Changes to shape or height, dormers, and work on listed buildings or conservation areas often do.
How long does a new roof last?
It depends on the covering, from around 40 to 60 years for concrete tiles to 80 to 100 years or more for natural slate, with flat roofs generally shorter.
Should I repair or replace my roof?
If repairs would cost around 30 to 40 percent of a full re-roof, or the roof is near the end of its life, replacing is often better value.
Final Thoughts
A new roof is a significant investment, and the price depends mainly on size, covering and access. Use the ranges here as a guide, get several itemised quotes, ask about hidden damage and asbestos, and compare like with like. A well-fitted roof should last for decades, so it pays to choose carefully.
