Common questions
How much does it cost to replace a roof in the UK?
Checkatrade puts the UK national average around £7,000 (before VAT) for a typical 64 m² gable roof, at £110–£260/m² depending on pitch, material, and region. Those trade figures exclude VAT, so our estimate adds the standard 20% on top — making the headline total VAT-inclusive (about £8,900 for that average roof), which is what you actually pay. A standard semi-detached with concrete tiles falls toward the lower end; premium slate or steep hip roofs toward the upper.
Does the estimate include removing the old roof?
Yes — toggle 'Remove old roof' to include tear-off and disposal. Checkatrade puts old-roof removal at £1,000–£2,500 for a typical gable, which works out to roughly £15–£39/m².
