A re-roof (sometimes called a roof replacement) usually means stripping off the existing tiles or slates and renewing the roof covering so it’s watertight for the long term. For many UK homes, it’s one of the biggest maintenance jobs you’ll ever do — but done properly, it can set you up for decades.
This guide is specifically about re-roofing pitched roofs covered in tiles or slates. You’ll learn:
- what a re-roof actually includes (and what it should include)
- typical UK cost bands and the biggest price drivers
- tile vs slate comparisons (cost, lifespan, repairability, look)
- a regional cost comparison and a quote checklist
What “re-roofing” means (and what it doesn’t)
A re-roof typically involves:
- removing existing tiles/slates (and disposing of waste)
- inspecting the roof structure (timbers/rafters)
- renewing underlay (felt/breathable membrane)
- renewing battens
- retiling or reslating with new (or sometimes reclaimed) materials
- renewing ridge/hip details as needed
- renewing leadwork/flashings where required (chimneys, valleys, abutments)
A re-roof doesn’t automatically include:
- insulation upgrades (unless specified)
- guttering/soffits/fascias (separate roofline work)
- structural alterations (unless issues are found and agreed)
Re-roof cost overview: what homeowners typically pay
A re-roof quote can vary a lot because access and complexity matter as much as the roof area.
Typical price bands (guide only)
| Re-roof scenario | Typical UK range | Notes |
|---|---|---|
| Small re-roof area (e.g., dormer/extension pitched roof) | £2,500–£7,000 | Access and detailing dominate |
| Typical house re-roof (simple shape) | £5,000–£15,000 | Size, scaffold, material choice |
| Complex re-roof (multiple valleys/dormers/chimneys) | £10,000–£30,000+ | Complexity + labour + leadwork |
These bands are for budgeting. For accurate roofing prices, roofers will look at:
- roof size and pitch
- number of elevations
- access for scaffolding
- condition of underlay/battens/timbers
- tile/slate choice and availability
Cost per m²: tile vs slate re-roof (budgeting guide)
Different roofs have different labour time, and slate often needs more careful fixing and handling.
| Covering type | Typical installed budget band (per m²) | Why it varies |
|---|---|---|
| Concrete tiles | £120–£220/m² | Often the most cost-effective option |
| Clay tiles | £140–£260/m² | Material cost + weight/details |
| Natural slate | £160–£300+/m² | Higher labour + material; complex detailing |
| Synthetic slate | £140–£240/m² | Material cheaper than natural; install still skilled |
If you’re comparing quotes, make sure both are quoting the same type (e.g., “natural slate” vs “synthetic slate”) and similar quality/brand tier.
What makes re-roof quotes expensive? (the big price drivers)
| Driver | Why it increases cost |
|---|---|
| Scaffolding | Safe access is often essential and can be a large line item |
| Roof complexity | Valleys, hips, dormers and multiple chimneys add labour |
| Leadwork | Chimneys/valleys/abutments require skilled detailing |
| Waste disposal | Strip-off creates bulky waste; skips add up |
| Timbers needing repair | Rotten battens or damaged rafters need extra work |
| Matching/heritage materials | Older homes may require specific tiles/slates |
Tile vs slate: which is better for a re-roof?
There’s no universal “best” — it depends on budget, appearance, and your property style.
Quick comparison
| Feature | Tiles | Slates |
|---|---|---|
| Upfront cost | Often lower | Often higher |
| Look | Wide choice; suits most UK homes | Premium look; great on period homes |
| Weight | Can be heavier | Often lighter than concrete tiles (varies) |
| Repairs later | Easier to replace individual tiles | Repairs can be trickier; matching matters |
| Lifespan | Long (product dependent) | Often very long (natural slate especially) |
| Best for | Budget + durability | Premium finish + longevity |
Homeowner tip: if your area has many slate roofs (or your house is period), slate can preserve the “correct” look and may help resale appeal.
“What should be included?” re-roof scope checklist
This is where a lot of roofing quotes differ. One contractor may quote a “re-roof” but only include the visible covering.
Re-roof inclusions table (use this to compare quotes)
| Item | Should it be included? | Notes |
|---|---|---|
| Strip-off + disposal | Yes | Skips/waste should be clear |
| Underlay (membrane) | Usually yes | Modern breathable membrane is common |
| Battens | Usually yes | New battens reduce future issues |
| Ridge and hip system | Often yes | Traditional vs dry ridge systems |
| Leadwork | Often needed | Chimney, valleys, abutments |
| Verge details | Yes | Mortar or dry verge systems |
| Roof ventilation | If required | Especially if upgrading membranes/loft insulation |
| Making good | Yes | Tile replacements, tidy, minor repairs |
| Guarantee | Yes | Written workmanship guarantee matters |
Regional pricing: why London costs more (and what to expect)
Roofing prices tend to be higher in London and the South East due to labour rates and operating costs.
Simple uplift guide (budgeting only)
| Region | Typical uplift vs UK midline |
|---|---|
| London | +20% to +45% |
| South East | +10% to +25% |
| Midlands | baseline to +10% |
| North of England | -10% to baseline |
| Scotland/Wales/NI | baseline-ish (varies by local area) |
Example: midline quote vs London (illustration)
| Re-roof scope | UK midline | London |
|---|---|---|
| Straightforward tile re-roof | £7,000–£12,000 | £8,500–£16,000 |
| Straightforward slate re-roof | £9,000–£16,000 | £11,000–£22,000 |
Timescales: how long does a re-roof take?
| Job type | Typical timescale | Notes |
|---|---|---|
| Small pitched re-roof | 2–5 days | Depends on access and detailing |
| Typical house re-roof | 5–10 working days | Weather affects progress |
| Complex re-roof | 2–4+ weeks | Valleys/dormers/chimneys add time |
A good roofer will plan around weather and keep the roof weathertight during works.
How to request better re-roof quotes (what to include)
To get accurate quotes quickly, include:
- postcode area + property type + storeys
- whether it’s tile or slate now (and what you want going forward)
- any known issues (leaks, sagging, felt deterioration)
- photos from ground level/upstairs windows (safe only)
- whether you have chimneys/valleys/dormers
- access notes (driveway space for scaffold, conservatory below, etc.)
FAQs: tile or slate re-roof
Is a re-roof the same as a roof repair?
No. Repairs fix local issues. A re-roof typically replaces the roof covering and often renews underlay and battens for long-term performance.
Do roofers always replace felt and battens during a re-roof?
Many do, but it should be confirmed in writing. Some quotes only include new tiles/slates unless you specify the full scope.
Can you re-use old tiles or slates?
Sometimes. Reclaimed materials can reduce material cost, but labour and breakages can increase. It also depends on condition and matching.
Do I need scaffolding for a re-roof?
Usually yes for safe access and speed, especially on 2-storey+ homes or steep pitches.
Should I switch from tile to slate (or slate to tile)?
It depends on budget, appearance, and what suits your home. A roofer can advise on weight considerations and best fit for your roof structure.
Ready to compare tile or slate re-roof quotes?
A re-roof is a big investment, so written quotes with a clear scope are essential. Use your quote request to describe your roof type, property height, access, and whether you want tile or slate — then compare like-for-like.
