Roof, walls & outside
A slipped tile today, a ceiling stain tomorrow
After every windy night, a few thousand British roofs are one tile lighter. Spotted early, a slipped tile is one of the cheapest roof repairs there is. Left alone, it quietly retires the felt underneath and reappears months later as a brown ring on a bedroom ceiling.

How urgent is this?
Book a roofer this month
One displaced tile is rarely a today emergency, but it moves faster in winter. If water is already coming in, treat it as urgent instead.
Why one tile matters
Tiles do the heavy shedding, but the real waterproof layer is the felt or membrane beneath them. A missing tile puts a patch of that felt on full-time weather duty. On a modern roof with breathable membrane, that buys you time. On an older roof, the bitumen felt has spent decades going brittle in the heat, and the first winter of direct rain finds the holes.
That is the whole economics of this job: £150–£400 for a handful of tiles now, or a soaked ceiling, wet insulation and redecorating later. If a stain has already arrived indoors, start with what to do about a roof leak and come back here for the repair.
Spotting trouble from the ground
All of this is done with your feet on the ground and binoculars or a phone camera on full zoom. Never from a ladder, never from the roof. Walk far enough back (a neighbour’s drive or the opposite pavement works) that you can see each roof slope square-on.
The post-storm ground check
- Dark rectangles or shadows where a tile face should be
- Tiles sitting at a skewed angle against the pattern
- Broken tile pieces on the lawn, drive or in borders
- Gaps or wobbly-looking tiles along the ridge line
- Crumbs of mortar on the ground below verges and ridge
- The chimney junction: flashing lifted or peeled back
- From the loft in daylight: any pinpricks of light or damp felt
Ridge and verge tiles (the ones along the top and the gable edges) are worth special attention, because on older roofs they are held by mortar, and mortar retires without notice. Finding grey crumbs in the gutter or on the path is the classic early warning. Storms and overhanging branches are the usual culprits for everything else.
What the repair involves, and what it costs
For a roofer with the right access, swapping tiles is quick work: lift the neighbours, hook out the casualty, slide in a match. The craft is in matching old tiles (reclamation yards exist for exactly this) and in re-bedding or re-fixing ridge and verge tiles properly rather than smearing new mortar over old.
Typical tile-level repairs

Typical UK ranges, mid-2026, as a guide only. Your home, your area and the job itself all move the number — always compare real quotes.
Quotes for the same tile can differ by hundreds of pounds, and the reason is nearly always access, not greed. A tile reachable from a roof ladder is an hour’s visit. The same tile above a conservatory, or on a three-storey terrace, can need scaffold or a tower, and that cost is real. Ask each roofer how they plan to reach it, and ask for photos of the damage while they are up there; a phone picture of the actual problem is the cheapest survey you will ever get. The outside survival guide has the full quote-comparing ritual.

Quick answers
How urgent is a single slipped tile?
It is a this-month job, not a this-minute one. The felt underneath will hold off light weather for a while, but its condition is unknown until someone looks, and winter shortens the odds. If rain is already showing on a ceiling or in the loft, it has graduated to urgent and the roofer visit should be this week.
Can I replace a roof tile myself?
No. Any work on a roof means working at height with proper access equipment, and that is professional territory full stop. Your part of the job is detection: ground-level checks with binoculars after windy weather, photos on full zoom, and a look in the loft for daylight or damp. Leave the climbing to people paid and insured for it.
Why do quotes vary so much for one tile?
Access. A tile that can be reached from a roof ladder is a short visit; one above a fragile conservatory or three storeys up may legally and practically need scaffold, which multiplies the price. Materials matter less, though matching a discontinued tile from a reclamation yard adds a little. Compare quotes on how they reach it, not only the total.
My roof loses mortar rather than tiles. Same problem?
Related, and just as worth fixing. Mortar bedding on ridge and verge tiles cracks and falls out with age, leaving those tiles loose in exactly the spots the wind works hardest. Modern dry-fix systems clip them mechanically instead, cost more up front, and end the re-mortaring cycle. Crumbs on the path or in gutters are your early warning.
