Roof Replacement
The 60-second answer: Full roof replacement covers strip-and-replace of a tired pitched roof (slate, concrete tile, clay tile) or a flat roof (felt, EPDM, GRP) where repair stops making economic sense. Typical UK costs in our region: £4,500–£12,000 for a 3-bed semi pitched roof,
SIX THINGS, EVERY JOB
What you get with Eco Roofers
What we typically see on Nottinghamshire roofs
Nottinghamshire roof-stock splits roughly into Victorian + Edwardian terrace in central Nottingham (NG1, NG3, NG7), inter-war and post-war semis through Mapperley/Sherwood and the West Bridgford suburbs, ex-coalfield estates around Mansfield (NG18-NG20) and Worksop (S80-S81), plus pantile-and-stone period property in Newark and the Trent-valley villages.
Local weather notes. The county catches Trent-valley weather — fewer high-wind events than the Pennines but more sustained-saturation rainfall in extended wet spells. South-westerly storms strip tile fixings on the same nailing line.
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.

When full replacement is the right call
Six signals that say repair is past the point of economic sense:
1. Multiple leaks — three or more active entry points, or a single leak that’s reappeared after previous patches
2. Roof age — felt over 15 years, EPDM/GRP over 30 years, slate over 80 years (Welsh slate often outlasts that), concrete tile over 50–60 years
3. Visible deck rot — soft spots underfoot, sponginess, water staining on the ceiling below the roof
4. Sagging or dishing in the roof line — structural fatigue, not just membrane failure
5. Surveyor flagged at property purchase or insurance claim — Cat 2 or Cat 3 defect on a survey will price down by £2,000–£10,000
6. Building Regs trigger — any work over 50% of the roof area renews the obligation to upgrade insulation to current Approved Document L 2022 standard (U ≤ 0.18 W/m²K)
Roof replacement options
Pitched roof — full re-roof
Strip the existing tiles or slate, re-batten with fresh treated battens, breathable membrane (Tyvek or equivalent), then re-cover. Typical 3-bed semi:
- Concrete tile re-roof £4,500–£8,500 fitted (most common UK choice)
- Clay tile re-roof £6,000–£10,000
- Welsh slate re-roof (new) £6,500–£12,000
- Welsh slate re-roof (50% salvaged + 50% new) £4,500–£8,000 — saves money where original slate is mostly sound
- Stone slate re-roof (Yorkshire stock) £8,000–£15,000+ — premium material, harder to source
Includes: scaffolding, breathable membrane, treated battens, lead flashings at chimneys, ridge re-bedding, gutter checks, skip and waste removal, 10-year installation guarantee.
Flat roof — strip-and-replace
Strip the existing membrane, inspect deck, replace any rotted boards, fit new membrane:
- Like-for-like felt (cheap-and-cheerful, 10–15 year life) £1,500–£2,400 for 20m² extension
- EPDM rubber (25–40 year life, single-piece, no field seams) £1,500–£2,400 for 20m²
- GRP fibreglass (25–30 year life, foot-traffic rated, hard finish) £2,000–£3,000 for 20m²
- EPDM with warm-roof retrofit (Building Regs compliant, energy-efficient) £2,400–£4,500 for 20m²
For most jobs in our area we recommend EPDM with warm-roof retrofit — the £600–£1,200 premium pays back in 5–8 years on energy savings and removes the cold-roof condensation risk permanently. See warm roof retrofit.
Why CPC tells the truth about replacement
Google’s keyword data tells us competing roofers pay extreme amounts to put their ad in front of homeowners typing “roof replacement [town]”:
roof replacement nottingham— £25.24 per clickroof replacement mansfield— £14.34 per click
Those numbers reflect what a converted job is worth. £25 per click means roofers calculate they’ll close enough of those clicks at high-margin replacement-job prices to make £25/click economic. Translation: if you’re typing that search, you’re a buyer with a real budget — and competing roofers know it.
What it means for you: get 3 quotes, ask the 5 questions below, and pick the roofer who answers them clearest — not the cheapest. The £200–£500 difference between cheapest and best on a £6,000 job is not where the money is.
Five questions to ask any roofer quoting on roof replacement
1. What’s the spec — material, manufacturer, warranty? Should be a named tile/slate/membrane manufacturer with a written warranty (20+ years for membranes, 25+ years for tile/slate).
2. What’s the U-value of the finished roof? For pitched: should be 0.16 W/m²K or lower (post-2022 build requirement). For flat: 0.18 W/m²K or lower for warm-roof retrofit; non-applicable for like-for-like cold-roof replacement.
3. What scaffolding, skip, and waste-removal is included? All three should be in the fixed price. If a roofer quotes the roof and adds £400 for skip later, walk away.
4. What’s the contingency for hidden problems? Decking rot, hidden joist damage, lead flashing failures revealed during strip — should have a written cap (£300–£800 reasonable, depending on roof size). Open chequebook = red flag.
5. What’s the timeline and what happens if it rains? A typical 3-bed semi re-roof is 5–10 working days. Rain delays add 1–3 days. Make sure the quote includes full weatherproofing during the strip (tarp at end of each day).

FAQ
How much does a roof replacement cost in 2026 UK?
Pitched 3-bed semi: £4,500–£12,000 depending on material. 20m² extension flat roof: £1,500–£4,500. Warm-roof retrofit on flat: £2,400–£4,500. Larger or commercial roofs scale roughly linearly per m².
How long does a roof replacement take?
Pitched 3-bed semi: 5–10 working days. Flat 20m² extension: 1–3 days. Allow 1–3 days extra for rain in winter.
Can I stay in the house during a re-roof?
Yes — pitched re-roofs are noisy but the house stays habitable. We weatherproof at the end of every day so no internal damage from rain. Flat-roof retrofits are entirely external; minimal noise inside.
Will I need planning permission?
For like-for-like roof replacement, no — it’s permitted development. Material changes (slate to tile, or pitch changes) may need Building Control notification or planning consent, especially in conservation areas. We confirm what’s needed at quote stage.
What’s the warranty?
10-year installation guarantee from Eco Roofers, plus the manufacturer’s warranty on materials (20–25 years for membranes, 30–50 years for tiles/slate). All in writing on completion.
Will it add value to my house?
A new roof is essentially a “neutral” sale signal — buyers expect a sound roof and price down significantly when they find a flagged one. A new compliant roof avoids the £2,000–£10,000 price-down survey impact. It doesn’t add value over a similar property; it removes the discount.
Can I replace just half the roof?
Yes, if there’s a clear structural division (gable to gable, or flat-extension only). We can re-roof one elevation at a time. Cheaper but the materials may not match the older half perfectly — we’ll discuss at quote stage.
