What to do right now, step by step

Work through these in order. The first two matter most: water does the most harm in a ceiling or near the electrics.

Whatever you do, stay off the roof. Wet tiles are slippery and old ones crack underfoot. Falls from height are the most common kind of fatal accident at work in Great Britain: 31 of the 126 worker deaths HSE recorded in 2025/26 (HSE, provisional figures). Look from the ground instead, and keep people away from anything loose.

  1. Catch the water

  2. Make the electrics safe

  3. Move your things

  4. Deal with a bulging ceiling

  5. Check the loft, if it's safe

  6. Take photos

  7. Call a roofer

What the stain can tell you about where the leak is

Water rarely drips straight down from the hole. It runs along the felt and the rafters first, and the Department for Communities' roof maintenance guidance warns that "the internal sign of water penetration is often far removed from the defect" (Department for Communities, roof coverings). Still, where the stain shows narrows things down:

  • On or beside the chimney breast: usually the chimney, its flashing or its flaunching. See chimney repairs.
  • Under a flat-roofed extension or garage: a leak in the covering itself, often at a split, joint or edge.
  • Where a sloping roof meets a wall: often the flashing along that joint.
  • Only in heavy, windy rain: driven rain getting under tiles or behind a flashing.
  • On cold, dry mornings: probably condensation from the house, not a leak.

Tracing it properly is what my roof leak repair visit is for.

What to tell me when you call

When you ring 07306 077999, I'll ask a few questions to judge how urgent it is:

  • where the water shows, and how fast it's coming in;
  • what you can see from outside: a gap in the tiles, something loose, a full gutter;
  • your postcode.

If it's safe to take them, WhatsApp me photos of the stain and the roof. If water is still coming in when I arrive, I do a quick fix to stop it, then come back for the proper repair. I explain what's wrong and give you a free quote for it.

After the leak: drying out the ceiling and loft

Once the water has stopped, let things dry before redecorating. Lift any loft insulation that got soaked, because wet insulation holds damp against the ceiling. Open the loft hatch and a window to keep the air moving.

Don't leave it. Government guidance on damp and mould lists defective roofs among the causes to fix, and warns that damp and mould mainly affect the airways and lungs (UKHSA, damp and mould guidance). A dried ceiling stain comes back through ordinary paint, so it needs a stain-blocking primer first, and soft or sagging plasterboard needs a plasterer once the roof is fixed.
