If you are searching for how much does a new roof cost, the honest answer is that most full UK roof replacements fall somewhere between £6,500 and £14,500 for a typical three-bedroom semi-detached house.
Larger, more complex roofs can cost £20,000 or more. A small flat roof over a garage or extension may cost considerably less.
These are useful starting points, not fixed prices. The final figure depends on the roof area, shape, materials, access, scaffolding, labour and any hidden timber damage.
How much does a new roof cost in the UK in 2026?
A new pitched roof usually costs around £80 to £150 per m² installed, with a typical three-bedroom semi-detached home costing roughly £6,500 to £14,500. Flat roof replacements commonly range from £1,500 to £6,000, depending on materials, access and structural repairs.
Those figures generally cover the main roofing work, including materials and labour. However, quotes are not always calculated in the same way.
Some roofers include scaffolding, waste removal and VAT. Others list them separately. Always ask for a written breakdown before comparing prices.
Current cost guides from Rated People and MyJobQuote show how widely prices can vary between roof types and materials.
Typical total prices
- Small flat roof: around £1,500 to £3,500
- Garage flat roof: around £1,200 to £2,700
- Standard pitched roof: around £6,500 to £14,500
- Large or complex pitched roof: around £14,000 to £22,000+
- Premium slate or specialist roof: potentially above £20,000
These ranges are for guidance only. A proper inspection is the only reliable way to understand what your roof needs.
What does a new roof cost per square metre?
Typical installed prices range from about £85 to £150 per m² for concrete tiles, £120 to £190 for clay tiles, and £150 to £280 for natural slate. Flat roof systems commonly range from £50 to £150 per m² installed.
The price per square metre usually includes the roof covering, underlay, battens and labour. It may not include scaffolding, major timber repairs, insulation upgrades or changes to gutters and fascias.
A larger roof may have a lower price per square metre because the roofer can work more efficiently. A small or awkward roof can cost more per square metre because setup, access and minimum labour charges still apply.
How much does a concrete tile roof cost?
A concrete tile roof usually costs around £85 to £150 per m² installed. Concrete tiles are one of the most affordable pitched-roof options and are widely used across the UK because they are practical, durable and available in several styles.
Concrete tiles are heavier than some alternatives, so the existing roof structure needs to be checked before installation.
The final price can rise if the roof needs new battens, extra ventilation, replacement timbers or specialist detailing around chimneys and valleys.
Concrete tiles are often a sensible choice where keeping the overall cost under control matters. They are not automatically the best choice for every property, particularly where the existing roof uses lighter materials or the building has a specific traditional appearance.
How much does a slate roof cost?
A natural slate roof commonly costs around £150 to £280 per m² installed, although premium Welsh slate and complex roof designs can push the price higher. Synthetic slate is usually cheaper while still providing a similar appearance.
Slate costs more because the material is more expensive and installation requires care and experience. Individual slates may also need to be cut around roof features, which adds time.
Your roofer should check whether the roof structure can support the selected material. A like-for-like replacement may be appropriate for some older homes, while another property may need a different system.
Ask whether the quote includes new fixings, underlay, battens, ridge details and the removal of the old roof.
How much does a flat roof replacement cost?
A flat roof replacement usually costs between £1,500 and £6,000. Felt is generally the lowest-cost option, while EPDM rubber and GRP fibreglass cost more but can offer longer service life and different performance benefits.
Typical installed ranges include:
- Felt: around £50 to £110 per m²
- EPDM rubber: around £80 to £140 per m²
- GRP fibreglass: around £90 to £150 per m²
A small garage roof may cost around £1,200 to £2,700. A larger extension roof, or one needing new decking, insulation or joists, can cost considerably more.
The roof should have a suitable fall so water drains away. If water has been pooling, replacing only the top membrane may not solve the underlying problem.
What factors affect the cost of a new roof?
Roof size, pitch, shape, material, access, location and hidden structural damage all affect the final price. A simple roof with clear access may sit near the lower end, while a high or complex roof can cost much more.
Here are the main cost drivers.
Roof size
More roof area means more materials, labour and waste. But very small jobs may have higher costs per square metre because the roofer still needs to arrange transport, equipment and site protection.
Roof shape and pitch
Hips, valleys, dormers, roof windows and chimneys create extra cutting, flashing and sealing work. A steep roof also takes longer and may need more extensive scaffolding.
Materials
Concrete tiles tend to be more affordable. Clay tiles, natural slate, leadwork and specialist systems usually cost more.
Access
A rear extension with easy access may be straightforward. A tall property, narrow passage, conservatory or neighbouring boundary can make the work slower and more expensive.
Location
London and the South East often sit towards the higher end of national price ranges because labour, transport and access costs are higher. Prices can be lower elsewhere, although local demand and the availability of experienced roofers still matter.
Hidden damage
Rotten rafters, damaged roof decking, failed flashing and inadequate ventilation may only become clear after the old covering is removed.
How much does scaffolding cost for a new roof?
Scaffolding for a typical house roof can cost roughly £900 to £3,000, depending on the height, number of elevations, access and how long it remains in place. It may be included in the roofing quote or charged separately.
Scaffolding is not just an optional extra. A professional roofer must plan safe access for work at height.
Ask these questions before accepting a quote:
- Is scaffolding included?
- How long is the hire period?
- Is a scaffold alarm or pavement licence needed?
- Will extra charges apply if bad weather delays the work?
- Does the price cover all elevations of the house?
A quote that appears cheaper may simply leave scaffolding, waste or permits out of the headline figure.
What is usually included in a new roof quote?
A standard roof replacement quote often includes stripping the existing covering, fitting new underlay and battens, installing the chosen tiles or membrane, labour and basic waste removal. Confirm every item because quotes differ between roofers.
A full quote may include:
- Removal of old tiles, slate or membrane
- New breathable underlay
- New battens
- Roof tiles, slate or flat-roof covering
- Ridge and verge work
- Basic lead flashing
- Labour
- Skip hire or waste removal
- Final site clean-up
It may exclude:
- Scaffolding
- VAT
- Major timber repairs
- New insulation
- Fascias and soffits
- Gutter replacement
- Roof windows or skylights
- Asbestos removal
- Planning or building control costs
Do not compare two quotes until you know they cover the same work.
What should you ask a roofer before accepting a quote?
Ask for a written, itemised quote that explains the materials, preparation, access, waste removal, guarantees and possible extras. Check insurance, relevant experience and whether building regulations paperwork will be provided after the work.
Useful questions include:
- Have you inspected the roof in person?
- Is the price based on measurements or a rough estimate?
- What happens if rotten timber is found?
- Are scaffolding, skips and VAT included?
- Which brand and grade of materials will you use?
- How long should the work take?
- What guarantee do you provide?
- Do you have public liability insurance?
- Will you provide building regulations certification where required?
- Can you show examples of similar completed roofs?
A proper roofer should be comfortable answering these questions. Be cautious of pressure to make an immediate decision or unusually low prices with no written detail.
Do I need a roof replacement or just a repair?
You may only need a repair if the damage is limited to a few tiles, flashing, a small leak or a localised section. Replacement is more likely when problems are widespread, recurring, or linked to failing structure and an ageing roof.
Look for signs such as:
- Repeated leaks
- Sagging areas
- Widespread cracked or missing tiles
- Damp or daylight visible in the loft
- Rotten roof timbers
- Persistent problems after previous repairs
- A roof that has reached the end of its expected service life
Do not assume a complete replacement is necessary because of one leak. A survey should identify whether repair or replacement is the sensible option.
Why is a roof survey better than an online estimate?
An online estimate cannot see your roof’s condition, shape or access. A survey lets a roofer measure the area, inspect the structure and identify problems that could change the price before work starts.
Online calculators are useful for getting a broad starting point. They cannot reliably account for:
- Hidden timber damage
- Roof pitch and unusual design
- Chimneys, valleys and dormers
- Limited access
- Scaffolding requirements
- Local labour costs
- Insulation or ventilation work
- Planning or building regulations issues
That is why a responsible cost guide should give a range rather than pretend to provide an exact price.
How can roofers win more quote requests from cost searches?
Homeowners often search for the price before they contact a roofer. A clear answer builds trust before the first conversation.
Roofers should explain realistic ranges, show what is included, name the factors that change the price and make it easy for a visitor to request the next step.
Your website should also make your service area, roof types and previous work clear. If potential customers cannot quickly understand what you do, they may contact a competitor instead.
Run the free VU1 audit to check your local, on-page and technical visibility. It takes under 15 seconds to request : the report lands within a few minutes.
For roofers who want ongoing visibility checks and a simple way to turn website visits into enquiries, join the VU1 membership for £99/month. Use the audit findings to fix the problems that stop local customers finding and contacting you.
You can also see the dedicated roofers trade page for a clearer view of how local search and quote requests work together.
What is the straight answer on new roof costs?
For most UK homeowners, budget around £6,500 to £14,500 for a standard pitched roof replacement in 2026. Smaller flat roofs may cost £1,500 to £6,000. Get an in-person survey before treating any online range as a quote.
Use online cost guides to understand the broad market. Then ask at least two or three experienced roofers for itemised quotes based on your actual property.
The cheapest quote is not always the best value. A clear scope of work, suitable materials, safe access and a written guarantee matter just as much as the headline figure.
