Roofing isn't licensed, so anyone can set up - and it's a trade with more than its share of cowboys. A big re-roof must meet building regulations; CompetentRoofer (the Government-authorised NFRC scheme) registers roofers who can self-certify that, and vets and inspects them at least twice a year. Check they're on it before you hire.

Check the CompetentRoofer register

Never agree to roof work from a cold-caller at your door or an unsolicited 'we noticed your roof' note — that is the classic roofing scam.

Get a written quote that itemises access (scaffolding or a tower), the exact materials, and the workmanship guarantee — not a vague day rate.

Be wary of demands for a large cash deposit; agree staged payments against work you can actually see completed.
