AbstractAlthough roof space ventilation may not be very effective in cold weather, it is required as the outside air warms up, to dry out moisture that may have accumulated in the roof space. This Note stresses the importance of reducing the movement of moisture from the living areas to the roof space and of ventilating the latter by means of vents distributed between the upper and lower parts of the roof to take advantage of both wind action and stack action
