TECHNICAL VLOGS - Condron Dry Ridge Installation Guide - ROOF TV UK

The Condron Dry Ridge Video Guide clearly explains how to install a dry ridge system to a) ventilate the roof space, or b) to ventilate the batten cavity. Depending on the type of underlay used, it may not always be necessary to ventilate the roof space (the space between the insulation and underlay) as some underlays can remove excess water vapour to prevent harmful condensation forming in the roof or loft space. However, this can result in an overload of water vapour collecting in the batten cavity (the space between the underlay and roof tiles or slates), especially with some close fitting tiles or slates, resulting in premature failure of the roof system. Excessive water vapour in the batten cavity can also cause efflorescence to form on the undersides of concrete roof tiles, which can lead to staining on the visible surfaces of the tiles. So this video also shows how to ventilate and remove excessive water vapour from the batten cavity. www.masterroofers.co.uk
