For nearly three decades, Roofshield® has been trusted across the UK as a high performance, air and vapour-permeable roof underlay.
Initially launched by DON & LOW in 1996, Roofshield® transformed ventilation practices in pitched roofing—and continues to raise the bar in performance, ease of use and regulatory compliance.
Now weighing 196 g/m²—up from the original 185 g/m²—Roofshield® offers significantly enhanced water resistance and tear strength, ensuring superior performance on exposed job sites and in extreme weather conditions. It remains NHBC-accepted for non-ventilated cold-pitched roofs and is certified by the BBA for cold and warm applications.
Manufactured in the UK with complete vertical integration, Roofshield® ensures consistent quality and is available all year round. Its breathability supports healthy, dry roof spaces by allowing air and moisture vapour to escape—reducing the risk of condensation, mould and structural degradation.
As part of Don & Low’s sustainability efforts, Roofshield® includes ≥20 per cent recycled content and comes with an Environmental Product Declaration (EPD) for Scope 3 carbon reporting.
But beyond the product itself, Don & Low backs every roll of Roofshield® with a comprehensive technical support service. Their in-house experts oĪer the following:
- MEMBRANE SELECTION ADVICE
- U-VALUE CALCULATIONS
- CAD DETAIL SUPPORT
- INSTALLATION GUIDANCE
- COMPLIANCE HELP
What’s more, all this support comes at no extra cost, regardless of the size of the project. This ensures that roofing professionals can specify, install, and deliver confidently, knowing they have the full backing of Don & Low’s technical expertise.
