How Much Does It Cost to Fix a Roof Leak?
£150 – £900
per job
Fixing a roof leak costs between £150 and £900 depending on what is causing the leak and how accessible the affected area is. Finding the source of a leak is often the most time-consuming part of the job, as water can travel some distance from the entry point before it becomes visible inside. A prompt repair prevents far more costly damage to ceilings, insulation, and timbers.

Prices vary by region, property type and tradesperson. Always get at least two quotes.
What affects the price?
Cause of leak - a slipped tile costs little to fix; failed lead flashing around a chimney or valley takes longer and costs more
Roof accessibility - the higher and steeper the roof, the longer it takes and the greater the safety requirements
Scaffolding - required for most roof leak repairs above single-storey level and adds £600-£1,500
Extent of damage - if water has saturated roof insulation or damaged roof timbers, additional work beyond the weathertight repair is needed
Labour vs materials
Roofers charge £150-£250 per day. Tracking down and fixing a simple leak takes two to four hours; more complex repairs to flashing or valleys take a full day. Scaffolding is usually a separate hire cost.
Repair or replace?
If the same area of roof has leaked repeatedly despite repairs, it may indicate a systemic problem with the felt underlay or battens rather than a simple tile issue. In this case, stripping and replacing that section is likely more cost-effective than further patch repairs.
