  • Not tying into the existing wall properly
  • No lead flashing at the roof junction

Insist on

  • One written fixed price for the full scope — no open-ended hours.
  • Deposit of 10–20% at most; balance after you inspect the work.
  • Any extra work agreed and priced in writing before it starts.
  • Under 3 m² is usually permitted development; a brick porch is about 1–2 weeks.
