Roofing cost per m² in 2026: rates by material and what moves them
Roofers price by the square metre because it is the only way to compare like with like across different roof sizes. In 2026 the working range across UK domestic roofing runs from about £75/m² for concrete interlocking tile to £250/m² for good natural slate. This page sets out the rate for each covering, explains exactly what a rate should include, and covers the seven factors that push your roof up or down within its band.
- Concrete tile: £75–£120/m²
- Natural slate: £140–£250/m²
- Scaffolding is usually extra — £800–£2,000

2026 roofing rates per square metre
These are typical UK supply-and-fit rates for a full re-roof, including stripping the old covering, new breathable underlay, new treated battens, the covering itself and labour. They exclude scaffolding, structural timber repairs and VAT.
| Covering | 2026 rate per m² | Expected life | Notes |
|---|---|---|---|
| Concrete interlocking tile | £75 – £120 | 40–60 years | The UK default; fast to lay, large format |
| Concrete plain tile | £100 – £150 | 40–60 years | Small format, far more units per m² |
| Clay plain tile | £110 – £180 | 60+ years | Better appearance and longevity than concrete |
| Fibre cement / synthetic slate | £90 – £150 | 30–50 years | Slate look at a lower rate and weight |
| Natural slate | £140 – £250 | 80–100+ years | Welsh slate at the top; Spanish more affordable |
| Torch-on felt (3 layer, flat) | £70 – £120 | 15–25 years | Cheapest flat option |
| EPDM rubber (flat) | £90 – £150 | 20–30 years | Single-piece membrane, few seams |
| GRP fibreglass (flat) | £100 – £170 | 20–30 years | Seamless, rigid, good for foot traffic |
| Single-ply membrane (flat) | £110 – £180 | 25–35 years | Often manufacturer-warranted |
What a proper rate should include
The single biggest cause of wildly different quotes is that they are not describing the same job. A defensible per-m² rate for a pitched re-roof covers:
- Stripping and disposing of the existing covering
- New breathable underlay — not reusing the old felt
- New treated battens — not reusing the old ones
- The tiles or slates themselves, plus fixings
- Labour and normal eaves and verge detailing
What sits outside the rate, and should be separately priced: scaffolding, ridge and hip work, valleys, chimney flashings, roof windows, guttering, structural timber repairs and VAT.
The underlay and batten test
If one quote is 25 percent cheaper per m² than the others, check whether it renews the underlay and battens. Those two components are the reason most roofs need replacing in the first place — tiles usually outlive them. A re-roof that lays new tiles onto old battens is not a re-roof, and you will be doing it again.
The seven things that move your rate in 2026
1. Access and roof height
The largest swing factor after material. A bungalow reachable from a tower is a different job from a three-storey terrace requiring a full scaffold with a pavement licence. Because scaffolding is a fixed cost, it distorts the effective per-m² figure heavily on small roofs.
2. Roof complexity
A simple gable-to-gable rectangle is the cheapest shape there is. Every hip, valley, dormer, chimney and change of pitch adds cutting, lead work and time. A complex roof can run 20 to 30 percent above the headline rate for the same covering.
3. Pitch
Steeper roofs are slower and require more safety provision. Below about 20 degrees, some coverings become unsuitable altogether and you are pushed towards a more expensive system.
4. Dry-fix requirements
Current roofing standards require ridge and hip tiles to be mechanically fixed rather than relying on mortar bedding alone. Dry-fix systems cost more up front than a bag of sand and cement, but they do not need re-pointing every decade or two. If a quote proposes mortar-only bedding, question it.
5. Insulation and Building Regulations
Replacing more than about a quarter of the roof area triggers thermal upgrade requirements. On a pitched roof this is often satisfied at ceiling level; on a flat roof or a room-in-roof it usually means a new insulated build-up, which is why flat roof rates look high relative to their simplicity.
6. Timber condition
Nobody knows what is under the covering until it comes off. A good quote states a provisional allowance for timber repair plus a rate for anything beyond it, so you are not exposed to an open-ended variation.
7. Region
London and the South East typically sit 15 to 30 percent above the national rate, driven by labour costs, parking and access restrictions, and scaffold licensing. The North and parts of Wales and Scotland sit at or below the lower end — though slate is often cheaper in slate-producing regions.
A worked example
Take a three-bedroom semi with a 9m x 5m footprint and a 35-degree pitch. Multiplying the 45m² footprint by a pitch factor of about 1.3 gives roughly 58m² of roof slope.
| Line | Calculation | Cost |
|---|---|---|
| Covering, concrete interlocking tile | 58m² x £95 | £5,510 |
| Scaffolding | Lump sum | £1,200 |
| Ridge, dry-fix | 9m run | £650 |
| Chimney flashing renewal | One stack | £600 |
| Timber repair allowance | Provisional | £400 |
| Total (excluding VAT) | £8,360 |
Note that the effective all-in figure is about £144/m² — well above the £95 covering rate. That gap is why comparing headline per-m² rates alone is misleading, and why you should always compare total itemised quotes.
How to measure your roof roughly
For budgeting only, multiply the building footprint by a pitch factor: about 1.2 for a shallow 30-degree roof, 1.3 for a typical 35 to 40-degree roof, and 1.5 for a steep roof. Add roughly 10 percent for a hipped roof over a simple gable. A roofer will measure properly, but this gets you within range before the first conversation.

FAQs: roofing cost per m² (UK, 2026)
What is the average roofing cost per square metre in 2026?
For a standard pitched re-roof in concrete interlocking tile, expect roughly £75–£120/m² in 2026, covering strip out, new breathable underlay, treated battens, the covering and labour. Clay plain tile runs about £110–£180/m² and natural slate £140–£250/m². Scaffolding is normally quoted separately.
Does the per square metre rate include scaffolding?
Usually not. Scaffolding is priced as a separate lump sum, typically £800–£2,000 depending on property size, elevations and hire duration. Because it is a fixed cost rather than an area-based one, it makes small roofs look expensive per m² and large roofs look cheap. Always check whether a quoted rate is inclusive.
Why do roofing rates per m2 vary so much between quotes?
Mostly because the quotes are not describing the same job. A rate that assumes reusing existing battens and underlay will always beat one that renews both. Other variables are whether ridge and verge are dry-fixed or mortar-bedded, whether an insulation upgrade is included, how much timber repair is allowed for, and whether the roof has valleys, dormers and chimneys that slow the work down.
How do I measure my roof area for a rough estimate?
Take the footprint of the house and multiply by a pitch factor: about 1.2 for a shallow roof around 30 degrees, 1.3 for a typical 35–40 degree roof, and 1.5 for a steep roof. A house with a 9m x 5m footprint and a standard pitch gives roughly 58m² of roof slope. This is for budgeting only — a roofer will measure properly.
Is a flat roof cheaper per square metre than a pitched roof?
Not necessarily. Modern flat roof systems run roughly £70/m² for three-layer torch-on felt up to £170/m² for fibreglass, which overlaps with tiling rates. The flat roof figure usually includes a new deck and an insulation upgrade to meet current thermal standards, and the expected service life is shorter at around 20–30 years.
