Introduced in 1996 by Don & Low, Roofshield® was the first air and vapour permeable roofing underlay to hit the UK market, revolutionising an entire industry. With its advanced technology, this versatile and easy-to-install three-layer membrane allows the passage of moisture to significantly reduce the incidence of interstitial condensation and mould growth in pitched roofs while also providing a superior, weather-proof secondary barrier. By eliminating the need for ventilation, Roofshield® speeds up roof completion and reduces labour costs.

As a testament to its consistent 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.
