Tiled and slate roofing: UK costs compared in 2026
Choosing a roof covering is a choice about cost, weight, lifespan and looks — and the four rarely point the same way. Concrete tile is the value option, natural slate the premium one that outlives everything around it, and clay sits handsomely in between. This guide sets out 2026 UK prices per square metre, the practical constraints that rule options in or out, and how to compare quotes honestly.
- Concrete tile: £100–£160 per m², 40–60 year life
- Clay tile: £130–£210 per m², 60–100 year life
- Natural slate: £160–£260 per m², 80–100+ year life

The coverings compared
Rates below are supplied and fitted per square metre of roof area, including new battens, breathable underlay, fixings and waste removal, but excluding scaffolding, which is usually priced separately.
| Covering | 2026 cost per m² | Expected life | Weight | Minimum pitch |
|---|---|---|---|---|
| Concrete interlocking tile | £100 – £160 | 40 – 60 years | Heavy | About 17.5° |
| Concrete plain tile | £120 – £180 | 40 – 60 years | Heavy | About 35° |
| Clay pantile | £130 – £190 | 60 – 100 years | Medium | About 30° |
| Clay plain tile | £150 – £210 | 60 – 100 years | Medium-heavy | About 35° |
| Fibre cement slate | £110 – £170 | 30 – 50 years | Light | About 20° |
| Natural slate (Spanish/Brazilian) | £160 – £220 | 80 – 100 years | Medium | About 20° |
| Natural slate (Welsh) | £200 – £260+ | 100+ years | Medium | About 20° |
Concrete tiles
The default covering on most post-war British housing, and for good reason: they are the cheapest per square metre, widely available and quick to lay because interlocking profiles cover more area per tile. The trade-offs are weight — a concrete tile roof is significantly heavier than slate, which matters if you are changing covering — and appearance, since the surface pigment fades and the roof usually looks tired well before it stops working.
Clay tiles
Clay holds its colour because the colour is the fired material rather than a coating, so a clay roof at forty years old often looks better than a concrete one at fifteen. Handmade and machine-made clay plain tiles are the traditional covering across much of southern and eastern England, and pantiles dominate parts of the east coast. They cost more and are more brittle to work with, but on a period property they are frequently the only option a conservation officer will accept.
Natural slate
Nothing else lasts as long. Welsh slate roofs of a century and more are still in service, and the reason they get stripped is almost always the nails or the underlay rather than the slate. Welsh slate carries a substantial premium; Spanish and Brazilian slate offer most of the performance at a lower price and now make up the bulk of UK installations. Quality varies within imported grades, so ask what is actually being quoted — origin, thickness and grade — rather than accepting the word “slate” alone.
“Slate” on a quote can mean three different things
Natural slate, fibre cement slate and slate-effect concrete tile can all be described loosely as slate, and there is well over a hundred pounds per square metre between the extremes. Insist on the manufacturer and product name in writing before comparing prices.
Weight: the constraint people forget
Roof structures are designed for the covering they were built with. Swapping a slate roof for concrete tile can add a very significant dead load, and it may need the rafters strengthening or replacing — a cost that can dwarf the saving on materials. The change is much safer in the other direction. If you are considering a different covering from the existing one, expect a competent roofer to raise the structural question early; if nobody mentions it, that tells you something about the quote.
Pitch and exposure
Every tile and slate has a minimum pitch below which wind-driven rain gets past it, and on exposed sites those minimums rise. Shallow roofs rule out plain tiles and clay pantiles entirely, which is one reason 1960s and 70s houses with low-pitched roofs are almost universally covered in interlocking concrete tile. A roofer should confirm the pitch and headlap against the manufacturer’s guidance for your exposure zone, not just fit what you asked for.
Nail sickness and why good slate roofs still fail
On old slate roofs, the slates commonly outlive their fixings. Iron nails corrode, slates begin sliding off in ones and twos, and the roof develops a scattered, gap-toothed look. This is called nail sickness, and it is the classic case where the covering is fine but the roof needs stripping and re-laying. The good news is that sound slates can usually be reclaimed and re-laid on new battens and underlay with new fixings, typically saving thirty to fifty per cent against buying new slate — expect a proportion of breakage and plan to buy in some matching replacements.
Whole-roof costs on a typical house
| Property | Approx. roof area | Concrete tile | Natural slate |
|---|---|---|---|
| Terraced house | 50 – 65 m² | £5,500 – £9,000 | £8,500 – £15,000 |
| 3-bed semi | 65 – 85 m² | £6,500 – £11,000 | £10,000 – £18,000 |
| Detached house | 90 – 130 m² | £9,000 – £16,000 | £14,000 – £26,000 |
| Bungalow | 80 – 110 m² | £7,000 – £13,000 | £11,000 – £21,000 |
These include scaffolding, strip-out, new battens and underlay. Complex roofs with hips, valleys and dormers push towards the upper end because detailing takes disproportionate time.
Comparing quotes fairly
- Named product — manufacturer, range and colour, not a generic description
- Underlay type — breathable membrane rather than old-style bitumen felt
- Battens — graded and treated to BS 5534, all new
- Fixings — the current standard requires far more mechanical fixing than older practice
- Dry-fix ridge and verge — now effectively standard, and it removes future re-bedding
- Ventilation — at eaves and ridge, to keep the roof space dry
- Scaffolding — supply, hire period and dismantle
- Guarantee — workmanship term alongside the manufacturer’s product warranty
Look for NFRC membership, CompetentRoofer registration so the work can be self-certified under Building Regulations, and TrustMark. On a listed building or in a conservation area, ask specifically about heritage experience and check what the local authority will permit before you commit to a material.
FAQs: tiled and slate roofing
Is slate or tile better for a UK roof?
Natural slate lasts longest, at 80 to 100 years or more, and suits period and low-pitch roofs. Concrete tile costs least to install and suits most modern housing. Clay sits in between and holds its colour best. Weight and roof pitch usually narrow the choice before aesthetics do.
How much does a slate roof cost per square metre in 2026?
Natural slate typically runs 160 to 220 pounds per square metre supplied and fitted, with Welsh slate from about 200 to 260 pounds or more. Concrete tile is roughly 100 to 160 pounds and clay 130 to 210 pounds.
Can I replace slate with concrete tiles?
Sometimes, but concrete tile is considerably heavier than slate and the existing rafters may not be designed for the extra load. A structural check is essential, and any strengthening work can outweigh the material saving.
What is nail sickness?
It is the corrosion of old iron nails on a slate roof, which lets sound slates slip off one by one. The slates themselves are often reusable, so the fix is stripping and re-laying on new battens, underlay and fixings rather than buying a whole new roof covering.
How long do concrete roof tiles last?
Typically 40 to 60 years, though the surface pigment fades much sooner so the roof looks worn long before it fails. The underlay and battens beneath often reach the end of their life at a similar point.
