What to do if…
you discover wet insulation or dripping in the loft or attic after a storm

Short answer

Treat it as an electrical and structural risk first: if water may be reaching lights, wiring, or the consumer unit, keep electricity off and don’t touch anything wet—then stop the leak getting worse and document the damage.

Do not do these things

  • Don’t step into the loft if the ceiling below is bowing/sagging, plaster is cracking, or you can see water pooling on plasterboard (collapse risk).
  • Don’t touch wet light fittings, cables, junction boxes, or the consumer unit/fuse box.
  • Don’t switch power back on “to see if it still works” while anything is damp.
  • Don’t pull down wet insulation in a rush—fibres, dust, and hidden wiring make this a bad first step.
  • Don’t climb onto the roof during or just after a storm (slip/fall risk).
  • Don’t run dehumidifiers/fans in the affected area if you suspect water has reached electrics and you haven’t made it safe.

What to do now

  1. Pause and do a quick hazard check from a safe, dry place. Look for: water dripping through a ceiling light, buzzing/crackling, scorch marks, a “hot” smell, or bulging ceilings. If any of these are present, keep everyone away from that area.
  2. Make electrics safe before anything else.
    • If you can do it without touching anything wet and without standing in water, switch off electricity at the consumer unit (main switch).
    • If you can’t safely reach it, don’t try—call an electrician. If there’s an electrical hazard or power issue, you can contact your local electricity distribution network operator via 105.
  3. If you smell gas or suspect carbon monoxide, treat it as urgent. Open doors/windows, get everyone into fresh air, and call the National Gas Emergency Service (0800 111 999). If a gas appliance/flue has been physically damaged by the storm and you suspect leakage or carbon monoxide risk, treat that as urgent too.
  4. Catch and divert water to limit damage. Put a bucket/tray under drips, lay old towels, and (if safe) move stored items away from the wet area. If you can see a steady drip from a single point, a temporary plastic sheet under the drip can help guide water into a container.
  5. Document the situation before you disturb it. Take clear photos/video of: the wet insulation/dripping point, any ceiling stains below, and any damaged belongings. Note the time you first noticed it and which rooms are affected.
  6. Arrange urgent “make-safe” help. Contact:
    • Your insurer (home buildings/contents) to log the claim and ask what temporary repairs they want documented.
    • A roofing contractor for emergency tarping/temporary covering and to identify the entry point (missing tiles, flashing, valleys, chimney, skylight, gutters).
      If you rent, notify the landlord/agent immediately and keep your own photos/notes.
  7. Reduce mould risk once electrics are confirmed safe. Ventilate affected rooms (open windows if weather allows) and keep internal doors to unaffected rooms closed. Do not start pulling insulation out yet unless a professional advises it’s necessary for safety.
  8. If you suspect older/unknown insulation or dust (e.g., very old property or unusual boards/lagging), stop and get specialist advice. Don’t rip, sand, or bag unknown materials as a first step.

What can wait

  • You do not need to decide today whether to replace all insulation or “upgrade” anything.
  • You do not need to scrub stains or repaint now (cosmetic work can hide ongoing leaks).
  • You do not need to negotiate with contractors on permanent works until the leak source is identified and documented.
  • You do not need to throw away belongings immediately—just move them dry and photograph damage.

Important reassurance

Storm leaks are common and often look worse than they are because water spreads along timbers and plasterboard before it shows. Focusing on safety (electrics/collapse) and limiting further damage is the right first move.

Scope note

These are first steps to make things safe, limit damage, and buy time. Permanent roof repair, drying plans, and any insulation removal/replacement can be decided once the leak source and extent are confirmed.

Important note

This is general information, not a substitute for professional inspection. If you feel unsafe, cannot isolate electrics safely, or suspect gas involvement, treat it as urgent and get qualified help.
