Abstract
Since the late 1960s, the accepted solution, in ‘cold’ pitched roofing, has been to introduce ventilation into the loft space by openings to the outside at eaves and ridge. More recently, vapour permeable underlays are sometimes used as an alternative to ventilation. With the introduction of the unventilated cold pitched roof, there is a need to clarify the general principles and risks and identify approved construction techniques. By giving guidance on the technical risks associated with ventilated and unventilated forms of cold pitched roofs, this Good Building Guide responds to some of the confusion and conflicting views.
