Tile Roof Replacement Costs UK — What a Full Concrete or Clay Re-Roof Costs in 2026

Concrete, Clay, Interlocking and Plain Tiles

Before you can price a re-roof you need to know what is on the roof — and what the customer wants to go back on. The four broad categories below behave very differently on cost, weight and labour.

Concrete Tiles

Concrete tiles are the workhorse of post-war British housing. They are cheap to buy, widely available (Marley, Redland, Russell and Sandtoft dominate the market) and quick to lay because most are large-format interlocking profiles. The trade-off is lifespan: concrete tiles typically last 40–60 years, and older ones become porous and lose their surface coating, going soft and crumbly at the edges. The vast majority of full re-roofs you quote will be concrete-to-concrete.

• Material cost: £10–£25/m² for the tiles alone
• Typical lifespan: 40–60 years

Clay Tiles

Clay tiles are fired from natural clay and keep their colour for the life of the roof rather than fading like concrete. They are common on period and conservation-area properties and are often specified by planning conditions in such areas. Clay is more brittle and the tiles are smaller, so a clay roof takes longer to strip and re-lay — and the tiles themselves cost considerably more. Expect a clay re-roof to come in noticeably dearer than the concrete equivalent, both on material and on labour.

• Material cost: £30–£70/m² (handmade clay higher still)
• Typical lifespan: 60–100+ years

Interlocking Tiles

Interlocking tiles — available in both concrete and clay — have a lip on the side and head that locks adjacent tiles together, so they lay with a single lap rather than the double lap of plain tiles. Fewer tiles cover each square metre and they go down fast, which makes interlocking the cheapest profile to lay per m². Most modern concrete roofs are interlocking. If a customer wants to keep costs down and there is no planning constraint, a large-format interlocking concrete tile is almost always the value option.

Plain Tiles

Plain tiles are small, flat, double-lapped tiles — roughly 265 x 165mm — laid in a broken-bond pattern. They take around 60 tiles per m² against perhaps 10 for a large interlocking tile, so a plain-tiled roof is far more labour-intensive to strip and re-lay. Plain tiles (in clay or concrete) give the traditional look expected on period homes and in conservation areas. They are the most expensive profile to re-roof because of the sheer tile count and the slower laying rate.

• Tiles per m²: ~60 (plain) vs ~10 (large interlocking)
• Labour: significantly higher — budget more days on the roof

Why a Tiled Roof Needs Replacing

A re-roof is rarely about the tiles alone. By the time a roof is being recovered, several elements have usually failed together. Knowing what is driving the job helps you survey it properly and explain the scope to the customer. The common reasons are:

• Cracked or porous concrete tiles: Older concrete tiles lose their surface coating, absorb water, then crack and delaminate through freeze-thaw cycles. Once a roof is shedding tile fragments into the gutters, recovering is usually more sensible than spot repairs.
• Failed underlay or felt: The bituminous felt under older roofs perishes, cracks and sags into "swags" between rafters. Once the felt has gone there is no secondary barrier against wind-driven rain, and the only proper fix is a strip and recover with new membrane.
• Rotten or sprung battens: Old undersized or non-graded battens rot, split and let tiles slip. New BS 5534-graded battens go on as part of any recover.
• Nail and clip failure: Corroded fixings let tiles and ridge slip, especially after storms. "Nail sickness" on a whole roof points to a recover rather than piecemeal refixing.
• Sagging or spreading: A dipping ridge or bowed slope can indicate failed battens, overloaded structure or rafter spread. This needs structural assessment before any new covering goes on.

The Strip-and-Recover Process Step by Step

A full re-roof — stripping the old covering back to the rafters and rebuilding the whole system — is the only way to address failed felt, battens and fixings together. Quoting it properly means pricing every stage, not just the tiles. The sequence is:

• Scaffolding: Full edge protection and a working platform around the roof. On most two-storey homes this is a third-party cost of £900–£2,500 and is your single biggest fixed line after tiles.
• Strip: Remove all tiles, ridge, hip and verge, then the old battens and felt back to the rafters. Stripped material goes into skips — a busy strip can fill several, and skip and disposal costs add up fast.
• New breathable membrane: Lay a modern breathable underlay (a vapour-permeable membrane) across the rafters. This replaces perished felt, lets the roof void breathe and provides the secondary waterproof layer.
• New battens: Fix new BS 5534-graded, treated battens at the correct gauge for the chosen tile. Correct batten gauge is what sets the headlap, so this stage governs weather performance.
• Re-tile: Load out and lay the new tiles, nailed and clipped to BS 5534 wind-fixing requirements for the exposure of the site.
• Ridge, hip and verge: Finish the ridge and hip lines, form the verges, and fit new flashings to chimneys, abutments and around any soil pipes or rooflights.

Dry-Fix vs Mortar Bedding

How you finish the ridge, hip and verge is one of the most important choices on the job. The traditional method beds ridge and verge tiles in sand-and-cement mortar. Mortar is cheaper on materials but cracks and lets ridge tiles slip within 10–15 years, and most manufacturer guarantees now require mechanical fixing in addition to or instead of mortar.

Dry-fix systems use mechanically fixed plastic or metal ridge, hip and verge components with a roll of breathable ridge ventilation — no mortar at all. Dry-fix costs more upfront but is largely maintenance-free, complies with BS 5534, and is now the default specification on most new re-roofs. Quote dry-fix as standard and offer mortar only where a conservation requirement demands the traditional look. Dry-fix typically adds £400–£900 to a job over mortar bedding, but it is what protects you from callbacks.

Typical UK Re-Roof Prices in 2026

Pricing a full concrete-tile re-roof in 2026 generally lands between roughly £5,500 and £15,000+ depending on property type, roof size and access. Clay roofs sit above this, and plain tiles above that again. As a per-m² benchmark for a like-for-like concrete recover, most jobs work out at £100–£170/m² all-in including scaffolding, materials, labour and waste. Clay pushes this toward £140–£220/m², and plain tiles higher still because of the tile count.

• Terraced house (concrete, ~40–55m² per slope): from £5,500, typically £5,500–£8,000
• Semi-detached (concrete, ~50–70m² per slope): £7,000–£11,000
• Detached (concrete, ~80–120m² per slope): £10,000–£18,000+
• Clay equivalent: add roughly 25–50% over the concrete figure

These are guide figures for a straightforward gable roof with reasonable access. A complex hipped roof with multiple valleys, two chimneys and tight side access can easily push a semi-detached job past £13,000. Always measure and survey before you commit a number.

What Drives the Cost Up or Down

Two roofs of the same floor area can quote thousands apart. These are the factors that move the price, and the ones to nail down at survey:

• Roof size and pitch: Slope area is always larger than footprint — a steep pitch adds 30–40% to the plan area, and a steeper roof is slower and more hazardous to work, so it costs more per m² too.
• Access: A detached house with clear all-round access scaffolds quickly. Terraces with rear access only, conservatories below the eaves, or no room for a skip on the drive all add time and cost.
• Tile type: Interlocking concrete is cheapest; clay and plain tiles cost more on both material and labour. A switch from concrete to clay can add several thousand to the same roof.
• Scaffolding: The single largest fixed cost after tiles. Bigger and taller roofs, awkward gardens and longer programmes all increase the hire bill.
• Dry-fix upgrade: Dry-fix ridge, hip and verge adds material cost over mortar but is the modern standard and avoids callbacks.
• Chimney and valley complexity: Every chimney needs new lead flashing and soakers; every valley needs forming and lining. Hips, valleys and multiple penetrations all slow the job and add lead and labour.
• Hidden timber: Rotten rafter ends, fascias or sarking found once stripped are extra. Always flag this as a provisional item in the quote so the customer is not surprised.

Frequently Asked Questions

How long does a tiled re-roof take?

A straightforward concrete-tile semi is usually a 4–7 day job for a two- or three-person team, including scaffold up and down. Clay and plain-tiled roofs take longer because of the smaller tiles, and a complex hipped detached roof with valleys and chimneys can run to two weeks or more.

Can I overlay new tiles without stripping?

No — battening over an existing covering is not appropriate for a failed tiled roof. If the felt, battens and fixings have failed, they need replacing, which means a full strip back to the rafters. Overlaying also adds weight the structure may not be designed to carry.

Is concrete or clay better value?

Concrete is cheaper to buy and lay and is the value choice for most homes. Clay costs more upfront but keeps its colour and lasts longer, and is often required by planning in conservation areas. Where there is no planning constraint and budget matters, a large-format interlocking concrete tile gives the lowest cost per m².

Do I need building regulations or insurance-backed guarantees?

A like-for-like recover is generally classed as repair, but if you replace more than 25% of the roof or change the covering significantly, building regulations can apply — check with the customer's local authority. Offering an insurance-backed guarantee and working to BS 5534 reassures customers and helps you win the higher-value jobs.

Should I quote dry-fix or mortar?

Quote dry-fix as standard. It complies with BS 5534, needs no maintenance and protects you from slipped-ridge callbacks. Offer mortar bedding only where a conservation requirement demands the traditional appearance.
