We ventilate roof spaces by a variety of ways, such as airbricks in end walls or a sarking
felt under slates that "breathes" and lets moisture out.
If you have an old slate or tile finished roof then it's probable that there is no sarking
felt beneath the slates, so it will breathe happily.
The water was leaking out of the sarking
felt below the roof tiles.
