Title

Roof covering

Your product relies on the passage of air through the roof covering into the batten cavity. Are there any roof coverings that you consider too airtight? I ask because I have to retrofit ventilation into a fibre cement roof with condensation problems (ironically fitted with breathable felt) and I vaguely remember reading somewhere about the close fitting properties of fibre cement slates. Will these properties affect the function of the lapvent?
