Drips in the loft on cold mornings? Here’s why
Drips on the roof felt or droplets on nails on a cold morning are classic loft condensation. It’s fixable, and the answer isn’t less insulation.
Where the water comes from
Cooking, showers, drying clothes and breathing all put moisture into the air. Warm air carries it up into the loft, where it meets cold timber and felt and turns back to water.
Why insulating can show it up
A well-insulated loft is colder above the insulation. If the roof has poor airflow, condensation that was always borderline becomes visible.
What fixes it
Better airflow at the eaves and roof, sealing the gaps that let damp air up from the house, and making sure bathroom and kitchen fans vent outside, not into the loft.
Common questions
Is a little condensation normal?
Occasional light condensation on the coldest nights can happen. Regular drips are a sign something needs changing.
Should I remove my insulation?
No. Improve the ventilation instead.
