Slipped Roof Tiles: What's Happening and How to Fix It
A slipped roof tile is one of the easiest roof problems to spot from the ground, and one of the most urgent to fix. A tile that has come out of alignment exposes the felt and battens underneath to weather, destabilises adjacent tiles, and can fall off entirely in a strong gust. This guide covers what causes tiles to slip and what the proper repair costs.
What Causes a Tile to Slip?
The most common cause across Kent is failed original nail fixings. Older roofs were nailed with iron or steel nails that rust over decades. Once a nail has corroded, the tile is held only by overlap, and gravity loses to wind eventually.
Other common causes include mortar failure on bedded tiles (ridges, hips, verges all rely on mortar that fails after 30-40 years), broken metal clips on more modern roofs, batten rot underneath the tile losing the support, and direct storm force on already-loose tiles.
Why It Gets Worse Fast
A single slipped tile is a problem; a row of slipped tiles is an emergency. Wind catches the gap and lifts the next tile, then the next. We have seen jobs where one tile was reported on a Monday and a 2 sq m hole had appeared by Friday.
Proper Repair Costs (2026)
- Single slipped tile re-positioned and re-nailed: £180 to £280
- 2-3 tiles re-fixed in one visit: £200 to £380
- Section of tiles re-clipped/re-nailed (1-3 sq m): £400 to £750
- Slipped ridge or hip tile re-bedded: £180 to £350
- Multiple slipped sections (signs of wider failure): £700 to £1,500+
If you are losing tiles repeatedly across the roof, the original nail fixings have likely corroded throughout. At that point, individual repairs are throwing money at a wider problem and a strip-and-recover or full re-roof is usually the right financial decision.

Frequently Asked Questions
How urgent is a slipped roof tile?
Very urgent. A slipped tile destabilises adjacent tiles, exposes the felt to weather, and can fall in the next gust. Address slipped tiles within days, especially before a forecast storm.
Why do roof tiles slip?
The most common causes are failed nail fixings (corroded after decades), mortar failure on bedded tiles, broken clips, batten rot underneath the tile, or direct storm force on already-loose tiles.
How much does it cost to re-fix a slipped tile in Kent?
A single slipped tile re-positioned and re-nailed costs £180-£280 in Kent in 2026. Multiple tiles re-fixed in one visit work out cheaper per tile. Larger sections requiring re-battening cost £400-£750.
Can I push a slipped tile back into place myself?
Strongly advise against it. The tile needs a new fixing (nail or clip) once the original has failed, and roof access is genuinely dangerous. Most domestic falls in the UK happen from low-pitched roofs that look easier than they are.
What if many of my tiles are slipping?
Repeated slipping points to wider failure of original nail fixings. At that stage, ongoing individual repairs become poor value and a strip-and-recover is usually the better long-term decision.
Will home insurance cover slipped tiles?
Storm-related slips with documented wind speeds are usually covered. Slips caused by old nails simply rusting through are wear-and-tear and not covered. Photograph the damage immediately and check Met Office records for the date.
