What you get with Eco Roofers
What we typically see on Greater Manchester roofs
Greater Manchester roof-stock combines dense Victorian terrace (M14/M16/M21 — Rusholme, Whalley Range, Chorlton), inter-war semis through Didsbury and Withington, post-war estates through Wythenshawe and Salford, plus stone-slate cottage stock through the Oldham/Rochdale Pennine fringe.
Local weather notes. Wet-Atlantic weather means moss growth is markedly worse than the East Midlands — valley leaks and lead-flashing failure are more common.
Approved Document L 2022 sets the thermal performance baseline for new roofs (U ≤ 0.16 W/m²K pitched, ≤ 0.18 flat). On flat roofs, BS 6229:2018 sets the design and falls standard. Eco Roofers will guide you through any Building Control notification needed on your job.

What you actually pay for
When you commission a roof replacement, you’re paying for eight components:
1. Materials — tiles, slate, membrane, breathable underlayment, treated battens, lead flashings, fixings
2. Labour — typically 40-50% of total cost; 2-4 roofers for 5-10 working days on a typical 3-bed semi
3. Scaffolding — usually included in fixed-price quotes; £400-1,200 standalone if charged separately
4. Skip + waste removal — £200-500
5. Plant and tools — accounted for in the day rate
6. Overheads + profit — 15-25% of the gross
7. Insurance — Public Liability £2M is standard
8. Guarantee admin — Building Control notification (Competent Person Scheme) on warm-roof retrofits and structural work
A reputable quote separates labour, materials, and scaffolding. A vague “all-in” quote without that breakdown is a red flag.
Real 2026 UK prices by property type
Pitched roofs (re-roof, like-for-like or material change)

| Bungalow | £4,500–£8,000 | £5,500–£10,000 | £8,000–£14,000 | £7,000–£11,000 |
These figures cover like-for-like replacement on a structurally-sound property. Add costs for:
- Truss replacement or strengthening if joists are rotted or undersized: £2,000–£5,000+
- Loft conversion preparation if you’re converting at the same time: £3,000–£8,000 incremental
- Ridge upgrade to dry-fix (mortar-free ridge system): +£200–£500 typical
- Insulation upgrade above the joists to current Building Regs: +£500–£2,000 depending on existing
- Rooflight installation or upgrade: £400–£1,200 per Velux-equivalent
Flat roofs (extension, dormer, garage, porch)
| Roof size | Like-for-like felt | EPDM rubber | GRP fibreglass | EPDM + warm-roof retrofit |
|---|---|---|---|---|
| 6 m² (porch) | £400–£700 | £500–£800 | £700–£1,100 | £800–£1,400 |
| 12 m² (garage) | £700–£1,200 | £900–£1,400 | £1,200–£1,800 | £1,200–£2,400 |
| 20 m² (kitchen extension) | £1,500–£2,400 | £1,500–£2,400 | £2,000–£3,000 | £2,400–£4,500 |
| 30 m² (large extension) | £2,400–£3,600 | £2,400–£3,600 | £3,000–£4,500 | £3,600–£6,500 |
| 50 m² (very large or commercial) | £3,500–£5,500 | £3,500–£5,500 | £5,000–£7,500 | £6,000–£10,000 |
| 100 m² (commercial unit) | £7,000–£11,000 | £7,000–£11,000 | £10,000–£15,000 | £12,000–£20,000 |
For most flat-roof refurbishment work in 2026, we recommend EPDM with warm-roof retrofit — the £600–£1,200 premium over felt pays back in 5–8 years on energy savings, eliminates cold-roof condensation permanently, and delivers a 25–40 year membrane life.
What drives price variation within each range
Why some quotes come in at the bottom of the range
- Property is on a corner plot or at the end of a terrace (easier scaffold)
- Roof pitch is 30–40° (most efficient working angle)
- Existing deck and joists are sound — no rot to discover
- Ground access is good — driveway or street parking for materials
- Standard concrete-tile or felt — readily-stocked materials
- Roofer has spare capacity in the off-season
Why some quotes come in at the top of the range
- Property is mid-terrace with shared scaffolding requirement (negotiate with neighbours)
- Roof pitch is below 30° (slow, awkward work) or above 50° (high-risk, fall-arrest gear)
- Hidden deck rot or joist damage discovered after strip — contingency triggers
- Listed building or conservation area — consent admin + matched material premium
- Specialist material — stone slate, Welsh slate (vs concrete substitute), clay pantile match
- Roofer is at peak-season capacity (May-August) — premium pricing
- Multi-trade work (insulation, truss strengthening, rooflight install at the same time)
Regional variation across the UK
| Region | Typical % vs UK average |
|---|---|
| London + South East | +20–35% |
| South West | +5–15% |
| East Anglia | -5 to +5% |
| East Midlands (Notts/Derby) | 0–5% (UK baseline) |
| Yorkshire (South + West Yorks) | -5 to 0% |
| North West | -5 to +5% |
| North East | -10 to -5% |
| Wales | -5 to +5% |
| Scotland | -10 to 0% |
Eco Roofers’ Notts/South Yorks pricing sits at UK baseline (slightly below for Yorkshire towns). London-based readers should add ~25-30% to the figures above.
Hidden costs to ask about
Five line items some roofers leave out of the headline quote. Always check whether they’re included:
| Item | Typical cost if added separately |
|---|---|
| Scaffolding | £400–£1,200 |
| Skip + waste removal | £200–£500 |
| Building Control notification (warm-roof retrofits, structural work) | £80–£250 |
| Lead flashings at chimneys | £200–£600 |
| Ridge re-bedding (mortar-set ridge tiles) | £400–£900 |
| Gutter cleaning + minor repair during scaffold up | £80–£250 |
A reputable fixed-price quote includes all of these. A “low” quote that breaks them out is usually higher than the apparent figure.
When a roof replacement adds value vs neutral
A new roof is price-restoring, not value-adding. Three scenarios:
Value-restoring (most common): Property has a tired roof flagged at survey or visibly failing. Replacement removes the £2,000–£10,000 buyer’s-discount that an aged roof attracts. Net effect on resale: +£0 to +£2,000.
Value-protecting (mid-life replacement): Property has 5–10 years of remaining roof life. Replacement defers the failure curve and avoids future damage costs. Net effect on resale: +£0.
Value-adding (rare): Material upgrade (concrete tile → slate) or aesthetic transformation that genuinely changes property class. Net effect on resale: +£3,000 to +£10,000 typical.
For most homeowners in our region, treat roof replacement as insurance against bigger costs — not as a value-add investment.
Five questions to ask any roofer quoting on replacement
1. What’s the spec — material, manufacturer, warranty? (Named manufacturer, 20+ year warranty.)
2. What’s the U-value of the finished roof? (Pitched: 0.16 W/m²K. Flat warm-roof: 0.18 W/m²K.)
3. Are scaffolding, skip, and waste removal included? (All three should be in the fixed price.)
4. What’s the contingency for hidden problems? (£300–£800 cap reasonable.)
5. What’s the timeline + daily weatherproofing plan? (Don’t leave a roof open overnight in wet weather.)
A roofer who answers all five clearly is worth hiring.

FAQ
How much does it cost to replace an entire roof in the UK?
£4,500-£12,000 for a typical pitched 3-bed semi (concrete tile to slate range). £1,500-£4,500 for a 20m² extension flat roof. £2,400-£4,500 for a warm-roof retrofit on the same flat extension.
What is the cheapest time of year to get a new roof?
Late autumn through early spring (October to March) in the UK — quotes are typically £300–£800 cheaper than peak-season (May-August). Avoid mid-winter for any flat-roof work as adhesives need 5°C+ deck temperature.
How can I tell a dodgy roofer?
Five red flags: door-to-door cold caller, demand for cash deposit upfront, no fixed-price written quote, refuses to name manufacturer or quote a U-value, no public liability insurance certificate. See How to Tell a Dodgy Roofer for the full guide.
How much does it cost to reroof a 4-bed house?
£7,500-£14,000+ for a typical UK 4-bed detached in concrete tile. £9,500-£16,000+ in Welsh slate. £12,000-£20,000+ in stone slate. Add 25-30% for London and South East prices.
Can I just patch a tired roof to save money?
For roofs over 12 years old (felt) or 60 years old (slate), patches usually fail within 12-24 months and you pay twice. Sometimes even three or four times before the homeowner finally accepts replacement. Long-term economics almost always favour replacement.
Do I need planning permission?
For like-for-like replacement, no — permitted development. Material changes (slate to tile, pitch changes) may need Building Control or planning consent, especially in conservation areas. We confirm at quote stage.
