Your Common Roof Insulation and Ventilation Questions Answered

Current guidance is around 270mm of mineral wool at ceiling level. Just as important is that it does not block the ventilation path at the eaves, and that it is not compressed, because compressed insulation loses most of its value.

Almost always condensation rather than a leak. Warm moist air from the house rises into a cold roof space, and if there is not enough ventilation at the eaves and ridge it condenses on the underside of the felt and drips onto the insulation. Adding insulation without ventilation makes it worse, not better.
