Roofing underlays

Roof underlays are essential for virtually all tile and slate pitched roof constructions, helping to provide the second line of defence against wind-driven rain and snow. Helping to reduce the wind loading applied to the roof covering, Glidevale Protect offers one of the most comprehensive ranges of roofing membranes available for cold or warm roofs, working hand in hand with our associated ventilation products. All of our roofing underlays offer excellent water resistance and some of the best wind uplift performance ratings on the market, with products suitable for use across the UK and Ireland to resist the imposed wind loads for any given location, without the need for taped laps.
