Description.
Roofshield is an air and vapour permeable, highly water resistant roofing underlay that has been made to the same high specification for over 20 years. It has consistently met the evolving demands of the roofing industry with reliable performance that has been demonstrated in the some of the toughest locations around the world. Its characteristics allow even very complex pitched roofs to breathe, without the need for airgaps or secondary venting.
