What a Full Roof Replacement Quote Should Cover
Materials (~45% of cost)
- Tiles or slates — £2,500–£8,500 (concrete cheapest, slate most expensive)
- Breathable membrane — £350–£600 (Tyvek, Klober or equivalent)
- Battens — £180–£350 (BS5534 pressure-treated)
- Ridge & hip tiles plus dry-fix — £250–£600
- Lead flashings — £200–£500 (chimneys, valleys, abutments)
- Underlay, nails, clips — £150–£300
Labour & Site (~55% of cost)
- Roofer labour — £2,000–£4,500 (2-person team, 5–10 days on site)
- Scaffolding hire — £900–£1,800 (2–3 weeks)
- Skip & waste disposal — £350–£650 (old tiles can weigh 3–5 tonnes)

Tip: always insist on an itemised quote — rock-bottom prices usually cut corners on membrane grade, batten compliance, or scaffolding insurance.
Roof Replacement Cost by UK Region (3-bed Semi, Concrete Tile)
| Region | Typical Cost | vs UK Average |
|---|---|---|
| London | £9,500–£14,500 | +25% |
| South East | £8,500–£13,000 | +15% |
| South West | £7,500–£12,000 | +5% |
| Midlands | £6,500–£11,000 | Baseline |
| North / Yorkshire | £6,000–£10,500 | −8% |
| Wales | £6,200–£10,800 | −5% |
| Scotland | £6,500–£11,500 | −3% |
Materials are nationally priced; the regional gap is driven by labour rates and scaffolding hire. London is consistently 20–30% above baseline.
Roof Replacement Cost by House Type (2026)
Roof area, not floor area, drives the price of a new roof. The very smallest pitched re-roofing jobs — a single rear elevation on a compact terrace, for example — start from £2,500–£4,000 depending on region. Whole-roof replacements on family homes sit in the ranges below, fully installed including strip-off, scaffolding, waste disposal and VAT.
| House type | Roof area | Concrete tile | Natural slate | Duration |
|---|---|---|---|---|
| 2-bed terrace | ~50–60m² | £5,500–£9,000 | £9,500–£15,500 | 4–6 days |
| 3-bed semi | ~65–75m² | £6,500–£11,500 | £11,000–£18,500 | 5–7 days |
| Bungalow | ~75–90m² | £7,500–£12,000 | £12,500–£20,000 | 5–8 days |
| 4-bed detached | ~100–120m² | £11,500–£17,500 | £18,000–£28,000 | 8–12 days |
| Dormer / complex roof | ~90–130m² | £13,000–£22,000 | £20,500–£33,500 | 10–15 days |
Working in square feet? A 1,200 sq ft roof is roughly 111m² — the size of a typical 4-bed detached — so budget £11,500–£17,500 in concrete tile or £18,000–£28,000 in natural slate, fully installed. Our full roofing cost guide covers repairs, partial re-roofs and every material in more depth.
Durations are for concrete tile with straightforward two-storey access; add 2–3 days for natural slate. Bungalows have larger roofs than their floor plans suggest, but cheaper single-storey scaffolding partly offsets the extra area.
Roofing Cost Comparison: What Each House Type Pays
Mid-range totals for a concrete-tile re-roof, fully installed. The 3-bed semi (highlighted) is the UK’s most common re-roof job.
Real quotes span a range either side of these midpoints — a 3-bed semi runs £6,500–£11,500 depending on region and spec, with London and the South East typically 20–30% above the cheapest regions.
Re-Roofing Cost per m² in 2026
The easiest way to compare quotes across different-sized roofs is per square metre. These are typical UK supply-and-fit rates in 2026. They exclude scaffolding and waste disposal, which are priced per job rather than per metre — add roughly £1,300–£2,450 for both on a typical semi.
| Roof covering | Supply + fit per m² | Notes |
|---|---|---|
| Concrete interlocking tiles | £85–£140 | Cheapest mainstream option; large-format tiles are fastest to lay |
| Fibre-cement slate | £110–£160 | The slate look for 25–35% less than natural slate |
| Clay tiles | £120–£185 | Better colour longevity; smaller format means more labour |
| Natural slate | £150–£240 | Longest lifespan; Welsh slate tops the range, Spanish slate is cheaper |
| 3-layer felt (flat roofs) | £70–£110 | Torch-on system: vapour barrier, underlay and mineral cap sheet |
| EPDM rubber (flat roofs) | £60–£120 | One seamless membrane, minimal joints to fail |
| GRP fibreglass (flat roofs) | £90–£140 | Seamless wet-laid laminate; needs dry weather to install |
Two caveats when you multiply up. First, small roofs carry a minimum-job premium — below about 30m² expect the top of these ranges, because setup, access and waste costs don’t shrink with the roof. Second, complex roofs with hips, valleys, dormers or chimney details add 15–30% to the effective rate. For material-by-material detail beyond replacement — repairs, partial re-roofs and flashing work — see our roofing cost guide.
Flat Roof Replacement Cost UK: Felt vs EPDM vs GRP
Flat roof replacement costs £1,500–£3,000 for a typical 25m² single garage or extension roof in 2026, rising to around £4,500 for a large or complex GRP roof. The three mainstream systems price — and age — very differently.
| System | Cost per m² | 25m² garage roof | Lifespan | Choose it when |
|---|---|---|---|---|
| 3-layer torch-on felt | £70–£110 | £1,500–£2,800 | 10–20 years | Budget is the priority, or you’re matching an existing felt roof |
| EPDM rubber | £60–£120 | £1,500–£3,500 | 30–50 years | Simple rectangular roofs — one seamless sheet, best whole-life value |
| GRP fibreglass | £90–£140 | £2,200–£4,500 | 20–30 years | Walked-on roofs, terraces and complex shapes with upstands |
Felt wins on upfront price — the simplest re-covers start from about £1,500 — but you may fit it two or three times over the life of one EPDM membrane, which is why EPDM usually wins on whole-life cost for a plain garage or extension roof. GRP costs more but sets as a hard, seamless laminate you can walk on, making it the default for balconies and roof terraces. It needs dry, mild weather to lay, so winter installs favour EPDM or felt.
One line to watch: if you’re re-covering more than about a quarter of the roof, Building Regulations Part L usually requires the insulation to be brought up to current standards at the same time — a warm-roof build-up typically adds £40–£80 per m² and is the most common hidden extra in flat-roof quotes.
What’s in a Re-Roof Quote — Line by Line
Three quotes for the same roof routinely differ by £2,000–£3,000, and the gap usually hides in what’s not itemised. Here’s what a properly broken-down quote for a 3-bed semi in concrete tile looks like in 2026, and the red flags to compare against.
| Line item | Typical range (3-bed semi) | Red flag |
|---|---|---|
| Strip old covering, skip & disposal | £950–£1,750 | Disposal missing or “by others” — old tiles weigh 3–5 tonnes |
| Timber repairs & new BS 5534 battens | £300–£700 | “Battens as required” with no rate — agree a per-metre price for timber repairs upfront |
| Breathable membrane | £350–£600 | No brand or grade named — “felt” alone tells you nothing |
| Tiles supplied (~70m² + 5% wastage) | £1,600–£3,200 | “Contractor’s choice” — insist on the exact product name |
| Ridge & hip tiles, dry-fix system | £250–£600 | Mortar-only bedding — dry-fix is the modern BS 5534-compliant standard |
| Lead flashings & valleys | £200–£500 | Old lead re-used with no price reduction |
| Labour (2-person team, 5–7 days) | £2,000–£4,000 | Open-ended day rate with no fixed duration |
| Scaffolding (full wrap, 2–3 weeks) | £900–£1,800 | Not itemised, or unclear whether erection, hire and removal are all included |
On scaffolding: a basic single-elevation lift starts from £430–£650, but a full re-roof needs wrap-around access on every worked elevation — our scaffolding hire cost guide breaks down prices by configuration so you can check this line against the market.
Individual lines won’t all sit at the top or bottom of their ranges at once; completed 3-bed semi re-roofs typically land at £6,500–£11,500 all-in. The fastest way to sanity-check any quote is to put it next to two others for the identical spec: get 3 free roofing quotes from vetted local roofers, or start a general quote request if your project bundles roofing with other work.
