The average roof repair in Cambridge costs £200–£800. But that range covers everything from a single cracked tile to fixing a leaking flat roof. This guide breaks down what you'll pay for different types of roof repairs — and what affects the price.
Roof Repair Cost by Type
| Repair Type | Cost Range | Time |
|---|---|---|
| Single tile replacement | £80–£150 | 30–60 mins |
| Multiple tile replacement (10–20) | £200–£400 | 2–4 hours |
| Leak diagnosis + repair | £150–£400 | 1–3 hours |
| Flat roof repair (small) | £200–£500 | 2–4 hours |
| Flat roof repair (large) | £500–£1,500 | 1–2 days |
| Chimney flashing repair | £200–£500 | 2–4 hours |
| Chimney repointing | £400–£800 | 1 day |
| Valley repair | £300–£700 | 3–5 hours |
| Ridge tile replacement | £150–£300 | 1–2 hours |
| Gutter repair/replacement | £100–£300 | 1–2 hours |
Tile Replacement Costs
Single Tile: £80–£150
Replacing one cracked or slipped tile is the most common roof repair. You're paying for:
- Access: Scaffolding or tower hire
- Labour: 30–60 minutes on the roof
- Materials: Tile (£5–£20 depending on type)
The minimum call-out fee for a roofer is typically £80–£120. Even for a 5-minute job, you're paying for their travel, equipment, and insurance.
Multiple Tiles: £200–£400
If you have 10–20 tiles cracked or slipped (common after storms), the cost per tile drops because the setup time is already paid. Budget £15–£25 per additional tile.
Leak Repairs
Diagnosis + Repair: £150–£400
A roof leak isn't always obvious. Water travels — the stain on your ceiling might be metres from the actual entry point. A proper diagnosis includes:
- Visual inspection from inside (loft) and outside (roof)
- Hose testing if the source isn't obvious
- Repair of the identified issue
Common Leak Causes
| Cause | Repair Cost |
|---|---|
| Cracked tile | £80–£150 |
| Missing mortar (ridge/verge) | £150–£300 |
| Flashing failure (chimney, valley) | £200–£500 |
| Flat roof puncture | £200–£500 |
| Blocked valley | £100–£200 |
Flat Roof Repairs
Small Repair: £200–£500
A puncture, split, or localised blister on a felt or rubber flat roof. Typically 1–2m² of repair area.
Large Repair: £500–£1,500
Multiple leaks, extensive blistering, or failed joints. May require stripping and re-covering a section.
Flat Roof Materials
- Felt: Cheapest, lasts 10–15 years. Prone to blistering and splitting.
- EPDM rubber: Mid-range, lasts 25+ years. Resistant to UV and temperature.
- Fibreglass (GRP): Premium, lasts 30+ years. Seamless, but needs professional installation.
Chimney Repairs
Flashing Repair: £200–£500
The lead flashing where the chimney meets the roof is a common failure point. Water seeps through cracked or lifted flashing. Repair involves removing old flashing, checking mortar, and replacing with new lead.
Repointing: £400–£800
Over time, the mortar between chimney bricks degrades. Repointing removes old mortar and replaces it, preventing water ingress and structural issues.
Chimney Removal: £800–£2,000
If the chimney is unused and causing problems, removing it entirely (below roof level and capping) is often cheaper than ongoing repairs.
What Affects the Cost?
1. Access
Easy access (detached house, good side access) keeps costs down. Difficult access (terrace with no side passage, steep pitch, multiple storeys) requires more equipment and time.
2. Height
Working at height requires scaffolding or towers. For 2-storey houses, scaffold hire adds £200–£400 to the job. For small repairs, roofers may use towers or harnesses instead.
3. Tile Type
Common concrete tiles are easy to match. Slate, clay tiles, or period tiles may require sourcing — and cost more per tile.
4. Urgency
Emergency call-outs (weekends, evenings, or during storms) typically cost 50–100% more. If your roof is leaking into a bedroom during a storm, you'll pay premium rates.
Repair vs Replace
Sometimes a repair isn't worth it:
| Roof Age | Condition | Recommendation |
|---|---|---|
| Under 15 years | Minor damage | Repair |
| 15–25 years | Multiple repairs needed | Assess for replacement |
| Over 25 years | Widespread issues | Replace |
A new roof costs £4,000–£8,000 for a standard semi-detached house. If you're spending £500–£1,000/year on repairs, replacement becomes better value.
When to Call a Roofer Immediately
- Water dripping into living spaces
- Visible daylight through the roof (from the loft)
- Sagging roofline
- Multiple tiles on the ground after a storm
- Mortar falling from ridge tiles
These issues get worse quickly. A small leak can become a major water damage problem in days.

FAQ
Is a roof leak an emergency?
If water is entering your living space, yes — it's an emergency. Place buckets to catch water, move valuables, and call a roofer. If caught early (stain on ceiling, damp in loft), you have more time to get quotes.
Can I claim roof repairs on insurance?
For sudden damage (storm, impact), possibly. For wear and tear or lack of maintenance, usually not. Check your policy and document the damage with photos before repairs.
How long do roof repairs last?
A properly done repair should last the remaining life of the roof. A patched flat roof area can last 5–10 years. Flashing repairs typically last 20+ years.
