Roof repair costs: slipped tiles, leaks, flashing and ridge work

Not every roof problem needs a full re-roof, and most issues homeowners run into are dealt with as a targeted repair instead. Prices for these jobs vary a lot depending on what's wrong and how easily the roofer can reach the affected area, but as a general benchmark, most roof repairs in the UK typically cost somewhere between £150 and £500, with larger or more involved jobs running up to £3,000 or more.

Slipped or missing tiles are one of the most common call-outs. Fixing a couple of dislodged tiles typically costs around £150-£300, largely reflecting the call-out and the time needed to safely access the roof rather than the tiles themselves, which are cheap. A larger patch of damage, say 10-20 tiles affected after a storm, commonly runs closer to £350-£700, since more of the roof needs stripping back and re-laying properly rather than just slotting a couple of replacements into place.

Leaks are trickier to price upfront because the repair cost depends entirely on the cause, which isn't always obvious from the ground. A leak can stem from a cracked tile, failed flashing, a deteriorated valley, blocked guttering pushing water back under the roof line, or even condensation rather than an external source. Because of this, many roofers charge a call-out or diagnostic fee to properly investigate before quoting a fixed price for the actual repair, and it's worth asking upfront whether that diagnostic fee is deducted from the final bill if you go ahead with the work.

Flashing, the metal (usually lead) strip sealing joints around chimneys, walls and roof junctions, is a frequent source of leaks once it corrodes or comes loose. Renewing flashing typically costs £200-£600 where access is straightforward, but rises to roughly £550-£1,100 once safe access at height is needed, and can reach around £1,500 where full scaffolding is required. This is a good example of how access, not just the repair itself, drives much of the cost on roof work.

Ridge tiles, the tiles running along the very top of the roof, are usually bedded in mortar that can crack and fail over time, letting water in at the highest point of the roof. Re-bedding or repointing ridge tiles and chimney mortar generally costs around £500-£1,300, depending on the length of ridge involved and how much of the existing mortar has failed.

Scaffolding is often the biggest single variable in a roof repair quote, and it's worth understanding why it gets added so readily. Standard ladders are fine for very minor, ground-level-adjacent work, but most roofers won't risk working at height without proper scaffolding or a scaffold tower once a job goes beyond the quickest fix, both for safety and because insurance often requires it. On a typical two-storey property, scaffolding commonly adds £500-£1,200 to a job, sometimes quoted from a starting point of around £800-£1,000, and this cost applies whether the actual repair takes an hour or a full day, since it's largely a fixed cost of getting safely up to the roof. For a small, cheap repair, scaffolding can end up being the majority of the total bill, which is why some roofers will try to combine several small jobs, or wait for a repair to become more urgent, before erecting scaffolding for a single tile.

Because access costs so much of the final price, it's worth asking any roofer whether a job can be done safely from a ladder or tower rather than full scaffolding, and getting written confirmation of what access method is included in the quote. It's also sensible to ask whether the same visit can address more than one issue — a slipped tile and some tired flashing, for instance — since combining jobs into a single scaffolded visit is usually far more cost-effective than paying for access twice.
