A new roof in the UK usually costs between £5,000 and £18,000, depending on the size of the property, roof type, materials, access, labour and any extra work needed.
For a straightforward tiled roof on a terraced or semi-detached house, many homeowners should expect to budget somewhere around £7,000 to £15,000. Larger detached homes, slate roofs, complex roof shapes or properties in older parts of Oxfordshire can cost more.
The honest answer is that no roofer can price a full roof properly without seeing it first. Two houses can look similar from the street but have completely different costs once you factor in pitch, scaffolding, old roof condition, chimneys, valleys, insulation, roofline and access.
Still, a clear guide can help you understand what is realistic before you start asking for quotes.
New Roof Cost at a Glance
Roof or property type Typical guide price
Small flat roof replacement £1,500 – £4,500
Garage or extension flat roof £2,000 – £6,000
2-bed terraced house roof £7,000 – £12,500
3-bed semi-detached roof £8,500 – £15,000
4-bed detached house roof £12,000 – £22,000
Large or complex detached roof £18,000 – £30,000+
Natural slate or heritage-style roof £15,000 – £35,000+
These are guide prices only. Your final cost can be lower or higher depending on the exact roof area, material choice and whether hidden issues are found once the old covering is removed.
New Roof Cost Per Square Metre
Most full roof replacements are priced partly around the size of the roof. As a general guide, a pitched roof replacement in the UK can sit around:
Roof type Typical cost per m²
Basic tiled pitched roof £100 – £140 per m²
Better quality tiled roof £130 – £180 per m²
Slate roof £160 – £250+ per m²
Complex roof with hips, valleys or dormers £150 – £275+ per m²
Flat roof system £45 – £140+ per m²
A simple roof with easy access will sit at the lower end. A steep, tall or awkward roof with multiple chimneys, valleys, dormers or roof windows will usually cost more.
What Affects the Cost of a New Roof?
- The Size of the Roof
The bigger the roof, the more materials, labour and time are needed. A larger roof also means more old tiles or slates to remove, more underlay, more battens, more fixings and more waste to dispose of.
This is why a detached house roof usually costs more than a terraced house roof, even if the material is the same.
- The Type of Roof
Some roof shapes are much quicker to replace than others.
A simple gable roof is usually more affordable because it has fewer awkward details. A hip roof, valley roof or roof with dormers takes longer because the roofer has more cutting, fixing, flashing and waterproofing work to complete.
Common details that increase cost include:
Chimneys
Valleys
Dormer windows
Rooflights
Lead flashing
Steep pitches
Multiple roof levels
Hard-to-reach areas
Shared terrace access
The more detail your roof has, the more labour it needs.
- Roofing Materials
Material choice has a major effect on the final price.
Concrete tiles are usually one of the more cost-effective options. Clay tiles cost more but offer a traditional finish that suits many older homes. Natural slate is more expensive again, but it can look excellent on period properties and last for many decades when installed properly.
For flat roofs, felt is often a more affordable option, while EPDM rubber and GRP fibreglass can offer strong long-term performance when fitted correctly.
Material Typical use Cost level
Concrete tiles Standard pitched roofs Lower to mid
Clay tiles Traditional homes Mid
Natural slate Period and premium roofs High
Fibre cement slate Slate-style finish at lower cost Mid
Felt flat roofing Garages, extensions, flat roofs Lower
EPDM rubber Flat roofs Mid
GRP fibreglass Flat roofs, modern extensions Mid to high
Leadwork Valleys, flashings, dormers High
The cheapest material is not always the best value. A poor-quality roof can lead to leaks, repairs and earlier replacement.
- Labour Costs
Roofing is skilled, physical and weather-dependent work. Labour often makes up a large part of the total cost because a proper roof replacement involves more than simply laying new tiles.
The team may need to:
Strip the old roof
Inspect the structure
Replace battens
Fit breathable membrane
Install tiles or slates
Complete ridge and hip details
Renew valleys and flashings
Check ventilation
Clear waste
Leave the property safe and tidy
Experienced roofers may not be the cheapest, but a roof is not the place to gamble on poor workmanship. Small mistakes around flashing, ventilation or fixings can cause expensive problems later.
- Scaffolding and Access
Most full roof replacements need scaffolding. This protects the roofers, your property and the public.
Scaffolding costs can vary depending on:
Height of the property
Whether access is needed front and back
Whether the scaffold needs wrapping
How long the job takes
Whether the scaffold sits on a pavement or public highway
Whether the property is terraced or has tight side access
In Oxford and many surrounding areas, access can be a real factor. Narrow streets, limited parking, terraced homes and older properties can all make a roofing job more complex.
- The Condition of the Existing Roof
A roof can look straightforward before work starts, but stripping the old covering sometimes reveals hidden issues.
Common surprises include:
Rotten battens
Damaged rafters
Poor previous repairs
Old felt failure
Rotten fascia boards
Damaged chimney brickwork
Weak roof decking on flat roofs
Leaking valleys
Insufficient ventilation
Water-damaged timbers
A good roofer will explain these issues clearly and show evidence before carrying out extra work.
- Insulation and Ventilation
When a large part of a roof is replaced, insulation and ventilation may need to be considered. This is especially important on older homes where the loft insulation may be poor or the roof has been suffering from condensation.
Improving insulation while the roof is open can be a smart investment because it may help reduce heat loss and make the home more comfortable.
Poor ventilation, however, can trap moisture. That is why a new roof should be treated as a full system, not just a covering.
What Is Usually Included in a New Roof Quote?
A proper new roof quote should be clear, itemised and easy to understand.
It should normally explain:
Removal of the existing roof covering
Scaffolding requirements
Skip or waste disposal
New breathable membrane
New treated battens
Tiles, slates or flat roofing system
Ridge, hip and verge details
Leadwork or flashing
Valley work if needed
Labour
Estimated timescale
VAT if applicable
Workmanship guarantee
Material guarantee
Any exclusions
Be careful with vague quotes that only say “replace roof” with one total figure. A cheap quote can become expensive later if scaffolding, waste, leadwork, insulation or roofline repairs are not included.
Hidden Costs to Watch For
Not every roof replacement comes with hidden costs, but it is sensible to budget for possible extras.
Scaffolding
Scaffolding can add hundreds or thousands of pounds depending on property height, access and how long it is needed.
Skip Hire and Waste Removal
Old tiles, felt, battens and rubble need to be removed responsibly. Waste disposal should be included or clearly listed in the quote.
Fascias, Soffits and Guttering
If your roofline is old or rotten, it often makes sense to replace fascias, soffits and gutters while the scaffold is already up.
Chimney Repairs
Chimneys are a common source of roof leaks. Repointing, lead flashing, flaunching or removing a damaged chimney stack can increase the final price.
New Leadwork
Lead valleys, chimney flashings and abutment flashings are important waterproofing details. If the old lead has split, lifted or been poorly installed, it may need replacing.
Rotten Timbers
If rafters, decking or boards are rotten, they must be repaired before the new roof covering goes on.
Building Control or Permission Requirements
Some re-roofing work may need building control approval, especially where a large part of the roof is being renewed, insulation is affected, structural changes are made or a heavier roof covering is used.
Listed buildings and conservation areas may also need extra care, especially if you are changing materials or altering the roof’s appearance.
New Roof Cost by Material
Concrete Tile Roof Cost
Concrete tiles are popular because they are durable, widely available and usually more affordable than slate or clay.
They are a practical choice for many modern homes and standard roof replacements.
Typical cost level: Lower to mid
Best for: Standard pitched roofs, budget-conscious replacements, modern homes
Clay Tile Roof Cost
Clay tiles have a more traditional appearance and are often used on older or character properties.
They can cost more than concrete tiles, but they offer strong kerb appeal and a classic finish.
Typical cost level: Mid
Best for: Period-style homes, traditional properties, visible roof elevations
Slate Roof Cost
Slate is one of the most attractive and long-lasting roofing options, but it is also one of the more expensive choices.
Natural slate is often used on premium, older or heritage-style homes. Fibre cement slate can offer a similar appearance at a lower cost.
Typical cost level: High
Best for: Period homes, high-end finishes, conservation-sensitive properties
Flat Roof Cost
Flat roof costs depend heavily on the system used. Felt is often cheaper upfront. EPDM rubber and GRP fibreglass can cost more, but they may offer better long-term performance when installed correctly.
Typical cost level: Lower to high, depending on system
Best for: Extensions, garages, dormers, porches and commercial flat roofs
How Long Does a New Roof Take?
A typical pitched roof replacement can take around 1 to 2 weeks, depending on the size and complexity of the property.
A small flat roof may take only a few days. A larger detached home, slate roof or property with difficult access can take longer.
Weather can also affect timing. Roofers can work through many conditions, but heavy rain, strong winds and unsafe conditions may delay progress.
Should You Repair or Replace Your Roof?
Not every roof problem means you need a full replacement.
A repair may be enough if:
Only a few tiles are missing
One small area is leaking
The lead flashing has lifted
A ridge tile needs repointing
The roof is generally in good condition
The issue is recent and localised
A full replacement may be better if:
The roof is leaking in several places
Tiles or slates are failing across the roof
The underlay has reached the end of its life
There is widespread nail fatigue
The roof has sagging areas
Repairs are becoming frequent
You are planning to sell and want peace of mind
The roof is old and no longer performing properly
As a simple rule, if you are spending money on repeated repairs every year, it may be time to compare the cost of ongoing patchwork against a proper re-roof.
Signs You May Need a New Roof
You may need to replace your roof if you notice:
Repeated leaks
Missing or slipped tiles
Cracked or broken slates
Daylight visible in the loft
Damp patches on ceilings
Sagging roof sections
Rotten battens or timbers
Moss and water sitting heavily on the roof
Failed flashing around chimneys
Old felt crumbling inside the loft
Rising energy bills caused by poor insulation
One small leak does not always mean a new roof is needed. But several warning signs together should be checked by a professional roofer.
New Roof Costs in Oxford and Oxfordshire
Roof replacement costs in Oxford can vary because the area has a mix of modern homes, older terraced properties, period buildings, conservation areas and larger detached homes across Oxfordshire.
Local factors that may affect cost include:
Narrow streets and restricted access
Terraced properties needing front and rear scaffolding
Older roofs with hidden timber issues
Slate or clay tile requirements
Conservation or listed building considerations
Parking and material delivery challenges
Chimneys, valleys and complex rooflines
Homes in areas such as Headington, Cowley, Summertown, Jericho, Botley, Kidlington, Abingdon, Witney and surrounding Oxfordshire villages can all have different roofing needs.
That is why a local roof assessment is the best way to get a realistic price.
How to Keep New Roof Costs Under Control
A new roof is a major investment, but there are smart ways to avoid overspending.
Get a Proper Roof Assessment First
A roof inspection helps separate urgent work from optional upgrades. It also gives the roofer a chance to check access, roof size, condition and hidden risks before quoting.
Compare Like-for-Like Quotes
Do not compare quotes by price alone. Check whether each quote includes scaffolding, waste removal, leadwork, ventilation, roofline work and guarantees.
Avoid the Cheapest Quote Without Detail
A quote that looks too cheap may not include everything needed. It may also rely on lower-quality materials or rushed workmanship.
Replace Roofline Items While Scaffold Is Up
If fascias, soffits or gutters are already worn, doing them during the roof replacement can save money compared with hiring scaffolding again later.
Choose the Right Material for the Property
Concrete tiles may be suitable for many homes, but they are not right for every roof. Slate, clay or specific tile profiles may be needed for appearance, planning or structural reasons.
Keep a Contingency Budget
Set aside extra funds for hidden timber repairs, chimney work or insulation upgrades. A sensible contingency can prevent stress if the roof reveals problems after stripping.
What Questions Should You Ask Before Hiring a Roofer?
Before agreeing to a new roof quote, ask:
What exactly is included in the price?
Is scaffolding included?
Is waste disposal included?
What materials will be used?
Are battens and membrane included?
Will you check the roof timbers?
Is leadwork included?
Are fascias, soffits and gutters included or separate?
How long will the job take?
What happens if rotten timber is found?
Do I need building control approval?
Is the work guaranteed?
Are you insured?
Can I see recent local work?
A professional roofer should answer these clearly and confidently.
Is a New Roof Worth It?
In many cases, yes. A new roof can protect your home from water damage, improve kerb appeal, reduce the risk of future leaks and make the property easier to sell.
It can also be a good time to improve insulation, ventilation, gutters and roofline details.
The key is to avoid treating a new roof as a quick cosmetic job. A properly installed roof should protect your home for decades.
