VAT: Many sole traders and small roofing firms are not VAT‑registered, so they do not add VAT. Larger contractors must charge 20% VAT. Always confirm before accepting a quote.
Labour makes up 35–50% of the total bill. The table below shows typical labour‑only rates for different roofing systems.
| Roofing Type | Labour Cost per m² | Team Size | Daily Output (m²) |
|---|---|---|---|
| Concrete/clay tiling | £28 – £40 | 2–3 | 15 – 25 |
| Natural slate | £35 – £55 | 2–3 | 10 – 20 |
| Standing seam metal | £45 – £70 | 2–3 | 8 – 15 |
| Flat roof (EPDM/felt) | £25 – £40 | 2 | 20 – 35 |
| GRP fibreglass | £35 – £55 | 2 | 10 – 18 |
| Cedar shingles | £40 – £60 | 2 | 8 – 15 |
Day rates for a roofing gang (two people) typically range from £350 to £550. Most contractors quote by the square metre for larger projects and switch to a day rate for small repairs or awkward roofs.
Replacing a worn‑out flat roof is one of the most common enquiries. The flat roof replacement cost per square metre UK varies significantly depending on the membrane chosen and whether the deck needs renewing.
| Flat Roof System | Replacement Cost per m² | Life Expectancy | Best For |
|---|---|---|---|
| Felt (3‑layer pour & roll) | £40 – £70 | 15–20 years | Budget garages, sheds |
| EPDM rubber | £50 – £80 | 30–50 years | Extensions, balconies |
| GRP fibreglass | £70 – £100 | 30–50 years | Complex shapes, upstands |
| Mastic asphalt | £80 – £120 | 30–40 years | Heritage, high‑traffic roofs |
| Liquid applied (polyurethane) | £60 – £95 | 20–25 years | Difficult details, gutters |
If the existing OSB or plywood deck is rotten, budget an additional £20–£40 per m² for deck replacement. Insulation upgrades (e.g., to meet Building Regulations) can add £15–£30 per m².
Premium roofing materials command higher rates. Here is a closer look at some of the most requested specialist options.
A zinc roof cost per square metre UK usually falls between £140 and £200, fully installed. Zinc is lightweight, durable, and develops a protective patina over time. Complex designs with multiple valleys or dormers push the rate toward the upper end.
An aluminium zinc roof cost per square metre UK ranges from £120 to £160. This pre‑finished steel product offers a similar aesthetic to zinc at a lower price point and is popular for contemporary extensions.
Copper roofing cost per square metre UK is among the highest, typically £190–£280. Copper’s longevity (80+ years) and distinctive verdigris finish appeal to heritage and high‑end projects.
Cedar roof shingles cost per square metre UK averages £90–£140. Western red cedar offers natural insulation and a traditional look, but requires regular maintenance to prevent moss and decay.
A mansard roof, often found on period properties, costs £100–£160 per m² depending on the covering (slate, zinc, or tiles). The complex geometry and steep pitch increase labour time significantly.
For a basic corrugated roof (agricultural or industrial), the average cost per square metre to corrugate a roof UK is £25–£45, making it the most economical sheet roofing solution.
Where you live strongly influences roofing costs per square metre UK. London and the South East consistently charge the highest rates, while Scotland and the North offer better value.
| Region | Concrete Tile Roof (per m²) | Slate Roof (per m²) | Flat Roof (EPDM, per m²) |
|---|---|---|---|
| London | £60 – £85 | £85 – £135 | £60 – £90 |
| South East | £55 – £78 | £80 – £125 | £55 – £85 |
| Midlands | £48 – £68 | £70 – £110 | £48 – £75 |
| North England | £42 – £60 | £65 – £100 | £42 – £70 |
| Scotland | £45 – £65 | £68 – £105 | £45 – £72 |
| Wales | £44 – £62 | £66 – £100 | £44 – £68 |
| Northern Ireland | £40 – £58 | £62 – £95 | £40 – £65 |
Regional estimates include labour and materials. Prices in individual postcodes may vary.
Use the formula below as a roofing costs per square metre UK calculator alternative. While not an interactive tool, it gives a reliable budget figure.
Total Cost = (Roof Area × Labour Rate) + (Roof Area × Material Rate) + Scaffold + Waste Removal
For a flat roof replacement of 25 m² with EPDM, the same method gives: labour £875, materials £650, scaffold £600, waste £200 = approximately £2,325.
| Project | Area | Material | Labour + Materials | Scaffold + Waste | Total (excl. VAT) |
|---|---|---|---|---|---|
| Terraced house re‑roof | 45 m² | Concrete tile | £2,835 | £1,050 | £3,885 |
| Semi‑detached re‑roof | 70 m² | Spanish slate | £5,460 | £1,300 | £6,760 |
| Extension flat roof | 22 m² | GRP fibreglass | £1,650 | £700 | £2,350 |
| Detached house, zinc standing seam | 90 m² | Zinc | £14,400 | £1,600 | £16,000 |

Roofing is a high‑risk trade that involves working at height, handling heavy materials, and ensuring weathertightness. For anything beyond a small shed roof, professional installation is strongly recommended. A poorly installed roof can leak, cause structural damage, and invalidate home insurance.
