Tiled roof repair and slate roof repair are the two jobs we do most often in London. Both need someone on the roof, matching the existing covering, and fixing the detail that actually failed rather than smearing sealant over it.
I have spent over 15 years on London roofs, and the pattern is consistent: the tile or slate nearest the stain is rarely the problem. Golden Roofing Expert Ltd works on clay and concrete tiles, natural and fibre-cement slates, and the ridges, hips and verges that hold them in place. We survey, photograph and quote in writing before starting. We are based at 10 Sale Pl, Tyburnia, London W2 1PX and cover the whole city.
In short:
- We trace the real entry point instead of replacing the tile nearest the stain.
- Repairs are matched to your covering, by profile, size, thickness and colour.
- You get photographs of every fault and a fixed written price.
- Surveys and quotes are free.
Common Tiled and Slate Roof Problems
- Slipped, cracked or missing tiles and slates
- Nail fatigue on older slates, causing them to slide
- Cracked or crumbling ridge and hip mortar
- Failed flashing around chimneys and abutments
- Storm damage and impact breaks
- Water tracking under lifted tiles at valleys and verges
A single slipped tile can let in more water than homeowners expect, because water runs down the underlay and appears metres away from the fault. That is why we trace the entry point rather than replacing the tile nearest the stain. On one Camden roof, the damp patch was in a back bedroom, but the failed tile was on the opposite slope near the ridge. You can see a finished job on our before and after roof repair in Camden page.
If water is coming in now, see our roof leak repair service. For related work, see our chimney repair service, roof repair service and roof cleaning service.
How We Carry Out Tiled Roof Repair and Slate Roof Repair
Repairs are matched to the covering, and the method depends on what is up there.
- Clay and concrete tiles. We use the same profile where possible, or reclaimed tiles if the roof is older. Matching discontinued tiles takes time, and I tell customers honestly when a repair will be slower because of it.
- Natural and fibre-cement slates. We match by size, thickness and colour. A single replacement slate usually cannot be nailed under the overlap, so we secure it with a lead or stainless-steel tingle, or nail it where it is accessible. On a larger area, we relay with the correct nails.
- Ridges and hips. We rake out failed mortar and replace it so it holds, not just looks tidy. Where the ridge tiles themselves are cracked or mismatched, we strip and relay them.
- Flashings and valleys. Lead is dressed and wedged, not sealed with mastic. The Lead Sheet Association sets out good practice for lead work.
Our process is simple:
- Inspection. We get on the roof, and into the loft where needed, and trace the fault.
- Photographs. You see what we see.
- Written quote. A fixed price for the work described, before anything begins.
- Repair. We protect your property, repair to match, and clear the site.
- Handover. We confirm what was done and leave you the after photographs.
Working on London Roof Types
Each roof fails in its own way.
- Victorian and Edwardian terraces in Camden, Islington, Kensington and Brent usually have natural slate or clay plain tiles. On slate, the usual cause is nail fatigue: the old iron nails corrode, and slates slide. If it is only a few, it is a repair. If it is widespread, repeated small repairs stop making sense.
- 1930s semis in Barnet, Harrow and Wembley typically have concrete interlocking tiles. The common faults here are cracked tiles, failed ridge mortar and lifted verges.
- Older properties often need reclaimed stock rather than a modern equivalent, which affects both timing and price.
If your building is listed or in a conservation area, there may be limits on what materials and details you can use. Historic England and the Planning Portal explain how to check with your council before work begins.
Cost of Tiled Roof Repair in London
Prices depend on the covering, access and how much needs repairing. These are typical London ranges for 2026, based on current UK price guides plus the usual London uplift of around 20–30%. Your own quote will depend on the survey.
| Job | Typical London price |
|---|---|
| Replace a few slipped or cracked tiles | £180 – £520 |
| Replace a few natural slates (matched) | £250 – £650 |
| Ridge or hip re-pointing or re-bedding | £450 – £1,500 |
| Valley repair | £350 – £1,100 |
| Larger repair across ridge, valley and slopes | £1,000 – £3,200 |
| Partial re-tile of one pitch | £2,000 – £5,000 |
| Scaffolding, where required | £500 – £1,200 |
What moves the price most:
- Access. Reaching the work safely can cost as much as the repair itself, so we confirm whether scaffolding is needed before booking.
- Material. Concrete tiles are cheapest to match. Natural slate, clay and reclaimed tiles cost more.
- One visit or many. It is far more economical to fix several faults in a single visit than to call someone out repeatedly. Ridge repointing, for example, can extend the life of a sound ridge by several years.
Repair or Replace? My Honest Advice
A few slipped tiles on an otherwise sound roof do not justify a new roof. A competent roofer can match the covering, replace the damaged pieces and re-dress the underlay in a morning. But when a significant proportion of the covering is cracked, porous or has lost its fixings, the cost of repeated repairs approaches the cost of replacement.
I tell people straight which side of that line their roof is on. Where a roof has passed the point of economical repair, we will explain the case for a new roof installation and quote for both options. A full re-roof on a London terrace usually starts at several thousand pounds, so it is worth knowing before you decide.
To stop small faults becoming big ones, ask about our roof maintenance service. If moss is part of the problem, see our roof cleaning in London page, and for stacks and flashing, our chimney repairs page covers lead work around chimneys. For a wider look at all our repair work, see our roof repair page.
Is a Slipped Tile an Emergency?
It can wait a short while in dry weather, but a slipped tile lets water under the covering. After a storm, the Met Office has advice on severe weather warnings, and I would not leave damage unchecked through the winter. If water is coming in, call us and we will make the roof safe while a permanent repair is arranged.
Please do not climb up to look. Falls from roofs are a leading cause of serious injury, and the Health and Safety Executive publishes guidance on safe working on roofs. Tiles and slates are also easy to crack under foot, which makes a small repair larger.

Tiled Roof Repair FAQs
Can you match my existing tiles?
Usually. We carry common profiles and source reclaimed tiles for older London roofs.
Is a slipped tile an emergency?
It can wait a short while in dry weather, but a slipped tile lets water under the covering. Book a survey rather than leaving it through the winter.
Do you repair ridges and hips?
Yes. We rake out failed mortar and repoint or rebuild the ridge and hip detail properly.
How much does tiled roof repair cost in London?
A few slipped tiles typically cost a few hundred pounds, ridge work and valleys more, and larger repairs more again. See the price table above, and we give a fixed written quote after the survey.
Can slipped slates be fixed without replacing the roof?
Often, yes. If only a few slates have slipped, we can re-fix them with lead or stainless tingles. If slippage is widespread because the nails have corroded, it points to a deeper problem and we will advise on the options.
Do you do scaffolding?
Where it is needed for safe access, we arrange it. We confirm before booking, and the cost is clear on your quote.
