Typical UK cost range
£250–£1,200
National baseline. City-specific ranges are adjusted for local labour and access costs on the city pages below. See the full UK cost guide for the methodology and the factors that move a quote.
What the job involves
Ridge tiles sit at the very top of the roof where the two slopes meet, bedded in mortar or held with mechanical dry-fix clips. On older mortar-bedded roofs the mortar fatigues after 20–40 years, the joint between the ridge tile and the slope opens up, and wind-driven rain starts getting underneath.
Repair options are (a) re-bed the existing ridge tiles with fresh mortar, or (b) remove and refit with a dry-fix ridge system. Current Building Regulations favour dry-fix for new work.
What changes the price
- Length of the ridge line and number of tiles.
- Mortar re-bed (cheaper) vs dry-fix conversion (more expensive but longer-lasting).
- Access, scaffold requirement for two-storey and above.
- Whether ridge tiles are intact or need replacing.
Timeline: Usually 1–2 days for a standard semi-detached house ridge.

Dry-fix or mortar — which is better?
Dry-fix is the current Building Regs preference for new work. It uses mechanical clips rather than cement mortar, which doesn’t crack as the roof moves and lasts 40–60 years. Mortar re-bed is cheaper upfront but has a shorter service life.
My ridge tiles look fine but there are gaps — is that a problem?
Yes, eventually. Wind-driven rain will get into the gaps and find the nearest route down through the underlayment. Gaps in a ridge line are one of the early warning signs that a re-bed is due.
