This guide is designed to fix that. It breaks down:
- the most common roofing jobs UK homeowners hire roofers for
- typical cost ranges (and why they vary)
- what should be included in a good quote
- when repairs are sensible vs when replacement is better value
- common add-ons (access, scaffolding, waste, making good)
Safety note: Don’t go on your roof. Roof work is high risk. Stick to ground-level checks and let professionals handle access.
Quick roof cost ranges (useful sanity checks)
- Minor roof repairs (few tiles, small leak, local flashing fix): £100–£300
- Moderate roof repairs (more tiles, ridge section, local valley/leadwork): £500–£1,000
- Major repairs (structural issues, large areas opened up): £2,500+
- New roof replacement: often quoted around £5,500–£12,000+ depending on size, type, materials and access (many “average” figures you see online sit around the mid-£7,000s, but your roof may be well above or below that)
These are broad benchmarks. Your real price depends on the specific job and access.
The most common roofing jobs (with typical costs and what’s involved)
1) Roof leak repair (finding the cause + fixing it properly)
What homeowners ask for: “My roof is leaking” / “Damp patch on ceiling” / “Leak only in heavy rain”.
What it usually involves:
- diagnosis (often junction-related: flashing, valleys, abutments, rooflights)
- lifting local tiles/slates to check underlay/battens where required
- reworking the defective detail
Typical cost range: often £150–£600 for straightforward leaks with easy access, rising to £700–£1,500+ where the leak involves chimneys/valleys, larger areas, or more difficult access.
Tip: A good roofer should show you photos of the defect before and after.
2) Replacing slipped or broken roof tiles (concrete/clay)
Common requests: “Replace broken tile” / “Replace missing tiles after storm”.
Typical pricing:
- Single tile replacement callout: £75–£150 (higher if access is awkward or tiles are hard to match)
- Small batch replacement (e.g., up to 5–10 tiles): £150–£350
- Larger patch re-tiling (by area): £120–£220 per m² (varies by tile type and roof complexity)
What a proper fix includes: lifting adjacent tiles carefully and checking the immediate area (battens/underlay) rather than “gluing” a tile in place.
3) Slate roof repairs (replacing slipped/broken slates)
Slates behave differently to interlocking tiles.
Typical pricing:
- Single/slate small repair visit: £120–£300
- Multiple slate replacement / local overhaul: £300–£900+
Costs increase when access is tricky or matching slates is difficult.
4) Ridge tile repairs (repointing, re-bedding, dry ridge)
Common symptoms: loose ridge tiles, cracks in mortar, bits of mortar on the drive/roof.
Typical pricing:
- Local ridge repair (small section): £200–£600
- Per metre pricing (where used): £50–£80 per metre
- Full ridge renewal (house dependent): £800–£2,500+
Note: If ridge tiles are loose, treat it as a safety issue as well as a leak risk.
5) Leadwork and flashing repairs (chimneys, dormers, roof-to-wall)
This is one of the most common “hidden” leak sources.
Typical pricing:
- Small/local flashing repair: £200–£600
- Full chimney flashing renewal (all sides, depending on access): £500–£1,500+
- Per metre pricing (where used): £50–£90 per metre
Watch-outs: cheap “mastic-only” solutions often fail because they don’t fix the detail underneath.
6) Valley repairs (GRP valleys, lead valleys, tile valleys)
Valleys carry concentrated water flow and fail fast when damaged or blocked.
Typical pricing:
- Local valley repair: £250–£900
- Per metre pricing (GRP valley repairs): £30–£60 per metre
- More complex valley renewal (lead/large scope): £800–£2,000+
If a valley is blocked with debris, cleaning may be part of the solution, but don’t accept “clean only” if the lining is damaged.
7) Flat roof repairs (garage roofs, extensions, dormer flat roofs)
Flat roofs commonly fail at edges, joints, outlets, and upstands.
Typical pricing:
- Small flat roof repair: £200–£700
- Localised repair by area: £150–£300 per m² (system-dependent)
Replacement context (useful for “repair vs replace” decisions):
- Small garage/bay roof replacement: often £900–£2,500
- Larger extension flat roof replacement: commonly £2,800–£7,500+ depending on size/system/access
8) Chimney-related roof work (pots, cowls, making safe, small repairs)
Roofers are frequently called for:
- making safe loose pots/cowls
- resecuring/removing dangerous loose elements after storms
- small repairs around the stack
Typical pricing:
- Small make-safe / minor chimney roof job: £150–£500
- If scaffolding is required: add £500–£2,000+ depending on access and duration
(Major chimney repointing/rebuild is usually priced separately as masonry work.)
9) Roofline work often bundled with roofing (fascias, soffits, guttering)
Many “roof leaks” are actually roofline failures:
- rotten fascia boards at eaves
- gutters overflowing into the roof edge
- missing/blocked eaves ventilation causing condensation issues
Typical pricing examples:
- Small fascia/soffit repairs: £150–£500
- Gutter repairs (local): £100–£300
- Bigger roofline renewals: often £1,000–£4,000+ depending on elevations/materials/access
Clarify scope so a roof repair doesn’t leave rotten timber untouched.
10) Rooflights / Velux repairs and replacement
Rooflights leak mostly because of the junction and flashing kit rather than the glass.
Typical pricing:
- Minor rooflight leak repair/detail work: £250–£800
- Rooflight replacement: often £1,000–£2,500+ depending on size, access, and making good
11) Full roof replacement (new roof / re-roof)
A full replacement typically includes:
- stripping old covering (where needed)
- new underlay and battens
- new tiles/slates and ridges/hips/verges
- making good leadwork and junction details
- waste removal
Typical pricing:
- Smaller roofs / simpler houses: £5,500–£9,000
- Average 3-bed homes (very rough): £7,000–£12,000
- Large, complex, slate, or high-access jobs: £12,000–£25,000+
Always compare what’s included: some quotes exclude leadwork, ventilation upgrades, timber repairs, or scaffolding.
Why roofing quotes vary so much
1) Access and safety (biggest driver)
If the roofer can safely do it with ladders and roof ladders, costs are lower. If they need a tower or scaffolding for safe access, costs rise — but the work is often better as well.
2) Roof type and materials
Slate, clay, and complex profiles can cost more than standard concrete tiles. Flat roof systems also vary widely in material and detailing.
3) Extent of hidden damage
Once tiles are lifted, roofers may discover:
- rotten battens
- damaged underlay
- decayed timbers at eaves
A good quote explains how these “unknowns” are handled (agreed variation, photos, and pricing method).
4) Area and seasonality
After storms or during winter, demand rises and emergency callouts can cost more. Even simple things like that can affect roofing prices in UK.
What a good roofing quote should include
Ask for a written quote that states:
- Scope: exactly what is being repaired/replaced
- Materials/spec: tile/slate type, leadwork scope, membrane type, ridge/verge method
- Access method: ladder/tower/scaffold and whether included
- Waste removal: included or extra
- Guarantee: length + what it covers (materials/labour)
- Assumptions: what’s included and what triggers extra costs
- VAT: shown clearly where applicable
If the quote is one vague line (“Fix leak — £450”), ask for a breakdown.
Roofers often use a lead generation service to get their work as a roofing job leads.
Repair vs replace: how to decide without overpaying
Repair is usually sensible when:
- the issue is localised (one valley section, one flashing detail, a handful of tiles)
- the rest of the roof covering is sound
Replacement becomes better value when:
- you’re repairing a different leak every year
- tiles/slates are failing across the roof
- underlay/battens are near end-of-life
- you’re doing major loft works anyway
A good roofer will explain where you sit on that spectrum — and show evidence.
FAQs
How much do roof repairs cost in the UK?
As broad benchmarks: minor repairs are often £100–£300, moderate repairs £500–£1,000, and major repairs £2,500+. Actual prices depend heavily on access and scope.
What’s the cheapest common roofing fix?
Replacing a small number of slipped/broken tiles or reseating a local detail can be one of the cheapest fixes — but only if access is straightforward.
How much does it cost to replace a broken roof tile?
A single tile replacement callout is commonly £75–£150, depending on access and how easy it is to match the tile.
How much is a new roof in the UK?
Many homes fall somewhere between £5,500 and £12,000+, but large, complex, slate, or high-access roofs can be significantly more.
Why does scaffolding change the quote so much?
Because safe access is expensive but often necessary to do details properly (chimneys, valleys, steep pitches). It can prevent rushed work and repeat leaks.
