Roofshield 1m x 50m

Roofshield® is the industry’s leading air and vapour permeable roofing underlay, earning over 25 years of trust through continuous use and rigorous testing. This innovative three-layer membrane, with a patented Meltblown core, allows the passage of moisture to significantly reduce the incidence of interstitial condensation in pitched roofs. 

Roofshield® provides a superior secondary barrier for roofs to protect against the ingress of rain, wind, and snow. When installed in cold-pitched roofs, Roofshield® eliminates the need for roof space ventilation since moisture diffuses through the underlay. As a testament to its performance and reliability, Roofshield® is certified by the BBA in the UK for use in unventilated cold and warm-pitched roofs in both fully supported and unsupported roofing applications. 

You may consider Vent3 Air as an alternative. Cromar have been working tirelessly over the last 2 years or so to develop this breather membrane that is more air permeable than others on the market and up to 10 x times more waterproof.
