How we find the leak. Inspections start with a methodical roof walk, then move to targeted testing. The team use moisture meters, close inspections of lead work and flashings, and thermal checks where access allows. For urgent problems call 07909 114109 or send a photo via WhatsApp for rapid advice.

Common leak sources we check:

  • Faulty lead work or slipped flashings around chimneys and dormers
  • Damaged or missing slates and tiles after storms
  • Poorly formed valleys and penetrations around vents and pipes
  • Blocked or broken guttering causing backflow at eaves

Frequently Asked Questions

We combine external roof checks with internal inspections at the loft and ceilings, then use moisture meters and targeted water testing to recreate the leak path. This method identifies where water enters the roof fabric so repairs target the actual failure point.
