Use this simple leak-prevention checklist to protect your loft, ceilings and insulation before heavy rain and frost.
Pre-winter leak prevention checklist
- Check loft spaces for fresh stains after rainfall.
- Clear all gutters and test downpipe flow.
- Inspect flashing around chimneys and abutments.
- Replace any broken or lifted tiles before frost cycles.
- Seal minor penetrations early to avoid winter expansion damage.
Why winter makes small leaks worse
Freeze-thaw cycles widen tiny gaps in mortar, lead joints, and tile overlaps. What starts as a minor drip can become a persistent ingress point.
When to call for urgent help
Any active dripping, spreading stain, or loft insulation dampness should be treated as urgent, especially before sustained bad weather.
