What roofers charge in Harrow

In Harrow, roof repair typically costs £175 – £920. Labour in Greater London runs 15% above the UK median, which accounts for most of the difference from the same job elsewhere.

How to choose between them

  • Check the registration yourself. Trade body memberships are public, and each body's own register confirms them in a minute.
  • Get three quotes on the same specification. Written down, split into labour, materials and anything structural. Most people compare a total against a total and end up choosing between two different jobs.
  • Ask what is not included. Making good, waste removal, scaffolding and VAT are the four that turn a cheap quote into an average one.
  • Never pay a large deposit up front. Materials in advance is normal. Half the total before anyone turns up is not.

Roofers in Harrow: common questions

How long should a new roof last?

Concrete tiles 40 to 60 years, natural slate 80 to 100, felt flat roofing 15 to 20, EPDM rubber 30 plus. Ask which is being quoted, because the price gap between felt and EPDM is small and the lifespan gap is not.

Should I ever use a roofer who knocks on the door?

No. Unsolicited doorstep roofing is the single most common home improvement scam in the UK. A legitimate firm has a verifiable address, an NFRC or TrustMark number you can check, and no reason to need a decision today.
