Old tiles stripped
The existing roof covering is removed so the roof can be checked and prepared properly.
Tiled roof replacement calculator
Tiled Roof Replacement Cost Calculator UK
Estimate the cost of replacing a tiled roof on a UK home based on roof size, tile type, roof shape, access, underlay, battens, existing condition and region. Use this calculator for concrete or clay tiled roofs before comparing quotes or checking cost per m².
What is actually replaced in a tiled roof replacement?
A tiled roof replacement is not only a swap from old tiles to new tiles. The quote should make clear what happens underneath the visible roof covering, because underlay, battens and detailing often decide whether the job is priced properly.
Underlay and battens checked
Underlay and battens are commonly replaced during a full roof replacement, especially on older roofs.
Timber issues identified
Rotten or damaged timber may only become visible once the roof covering is stripped.
New tiles installed
The chosen concrete, clay, interlocking or plain tiles are installed to suit the roof pitch and laying pattern.
Ridges, verges and flashing completed
Details around ridges, verges, valleys, chimneys and abutments affect cost and long-term weather resistance.
Waste removed
Old roof material, packaging and waste should be allowed for clearly in the quote.
Repairing tiles or replacing the roof?
A few missing or slipped tiles do not always mean the whole roof needs replacing. Replacement becomes more likely when leaks keep returning, underlay has failed or the roof covering is widely brittle, cracked or weathered.
| Tiled roof situation | Better starting point | Reason |
|---|---|---|
| A few slipped tiles | Roof repair | A local repair may be enough if the surrounding roof is sound. |
| One local leak | Roof repair | The issue may be local flashing, one damaged tile or a small failed area. |
| Repeated leaks | Tiled roof replacement | Repeated leaks can point to wider failure of underlay, battens or roof covering. |
| Brittle or failing tiles | Tiled roof replacement | Widespread tile failure can make patch repairs poor value. |
| Underlay failure | Roof replacement | The problem may sit beneath the visible tiles and affect a wider area. |
| Unsure whether the whole roof needs work | Roof replacement calculator | Start broad if the roof type or scope is unclear. |
Concrete, clay and plain tiles: how tile choice changes cost
Tile choice affects both material cost and labour time. A simple interlocking concrete tile can be quicker to install than a plain tile roof with a more detailed laying pattern.
| Tile type | Cost behaviour | Best suited to |
|---|---|---|
| Concrete tiles | Usually lower to mid-range | Standard UK homes and budget-controlled replacements |
| Clay tiles | Usually higher than concrete | Traditional appearance and stronger kerb appeal |
| Interlocking tiles | Often efficient to install | Practical replacements with a simpler laying pattern |
| Plain tiles | Can cost more in labour | Period-style roofs or detailed roof shapes |
Tiled roof or slate roof?
Tiled roofs are often the practical baseline for UK roof replacement. Slate usually sits higher because material and labour are more demanding. If you want a premium finish or are working on a period property, compare this estimate with the slate calculator.

Premium comparisonSlate roof replacement
Use this if appearance, period character, premium finish or longer-life comparison is part of the decision.
If you already have a quote, check it with the Roof Cost per m² Calculator. If you are still deciding whether the whole roof needs replacing, start with the Roof Replacement Cost Calculator.
Typical UK tiled roof replacement cost ranges
These are broad planning ranges. Use the calculator above for a more specific estimate based on tile type, roof area, access, roof condition, region and contingency.
| Project | Typical range | Best use |
|---|---|---|
| Small tiled roof replacement | £4,000–£9,000+ | Smaller homes, porches and simple roofs |
| Standard concrete tiled roof | £6,000–£16,000+ | Mainstream UK roof replacement |
| Clay tiled roof replacement | £8,000–£22,000+ | Traditional or higher-spec finish |
| Plain tile roof replacement | £10,000–£28,000+ | Labour-heavy or period-style roofs |
| Large or complex tiled roof | £15,000–£35,000+ | Detached homes, hips, valleys, dormers and chimneys |
What affects tiled roof replacement cost?
A tiled roof quote is shaped by the visible tiles and the hidden layers below them. Roof area, scaffold, underlay, battens, timber condition and detailing can all change the price.
Roof area and pitch
Larger and steeper roofs increase material, labour and safety requirements.
Tile type
Concrete, clay, interlocking and plain tiles have different material and labour profiles.
Underlay and battens
These are often replaced during a proper roof replacement and can change the quote.
Roof complexity
Hips, valleys, chimneys, dormers and rooflights add cutting and detailing time.
Access and scaffolding
Height, parking, terraced access, waste removal and scaffold setup can affect cost.
Existing condition
Rotten timber, failed underlay, loose ridges or poor previous repairs can increase scope.
Already have a tiled roof quote?
A quote should be checked against roof area, tile type, scaffold, underlay, battens, waste removal, leadwork, flashing, ridge details, verge details, VAT and exclusions. Use the Roof Cost per m² Calculator to sense-check the number, then compare it with the broader Roof Replacement Cost Calculator.
What should a tiled roof quote include?
The cheapest quote is not always the best comparison. A clear quote should show whether the roofer has allowed for the roof covering, the hidden layers, the detailing and the site setup.
Tiles and product details
The quote should name the tile type or product, plus any assumptions around colour, profile and finish.
Strip, disposal and scaffold
Removal of old tiles, waste disposal, scaffold and safety setup should be included or clearly excluded.
Underlay, battens and fixings
Underlay, treated battens and fixings should be listed because they are a major part of a proper tiled roof replacement.
Ridge, verge and flashing details
Ridges, verges, valleys, flashing, leadwork and chimney details can affect both price and weather resistance.
Roofline extras
Fascias, soffits, gutters and ventilation should be clear if they are part of the scope.
VAT and exclusions
VAT, provisional sums, hidden timber repairs and exclusions should be easy to identify before you compare quotes.
Replacing tiles as part of an extension or roof upgrade?
Tiled roofs can affect extension pricing when the project involves matching existing roof tiles, extending a pitched roof, adding rooflights, changing roof shape, tying into the existing roof or adjusting drainage and gutters.
If the tiled roof is part of a wider build, compare this estimate with the extensions cost calculators and the Home Extension Cost Calculator. If the project involves a low-pitch or membrane roof, use the Flat Roof Replacement Cost Calculator.
How this tiled roof estimate is calculated
The calculator starts with a tile type and base cost per m², then adjusts the range using property type, roof complexity, access and scaffolding, underlay and battens, existing condition, specification level, region and contingency.
This gives a planning range rather than a fixed quote. Tiled roof costs can change when the old covering is stripped and the underlay, battens, timber, flashing and roofline details can be inspected properly.
For more detail, read our methodology, pricing data and how costs are calculated.

Tiled roof replacement cost FAQs
How much does a tiled roof replacement cost in the UK?
A tiled roof replacement can range from around £4,000 for a smaller simple roof to £35,000+ for a large or complex tiled roof. Size, access, tile type, scaffold and condition all affect cost.
Are concrete tiles cheaper than clay tiles?
Concrete tiles are often cheaper than clay tiles. Clay tiles usually cost more because of material choice, appearance, handling and laying pattern.
What is included in a tiled roof replacement?
A tiled roof replacement commonly includes stripping old tiles, checking or replacing underlay and battens, installing new tiles, finishing ridges and verges, checking flashing and removing waste.
Do roof battens and underlay need replacing?
They are often replaced during a proper roof replacement, especially when they are aged, damaged or not suitable for the new tile system.
Is a tiled roof cheaper than slate?
Usually yes. A tiled roof is often cheaper than a slate roof because material and labour costs are generally lower.
Should I repair or replace a tiled roof?
Repair may be enough for a few slipped tiles or a local leak. Replacement is more likely when there are repeated leaks, failing underlay, widespread brittle tiles or poor previous repairs.
Why do tiled roof quotes vary so much?
Quotes vary because roof area, scaffold, tile type, underlay, battens, access, flashing, ridge details, waste removal and hidden timber issues can all differ.
Are CostIntel tiled roof estimates fixed quotes?
No. They are planning estimates based on typical UK tiled roof scopes and cost drivers. A roofer needs to inspect the property before giving a fixed quote.
