The 1m x 25m Breathable Roof Membrane is a high-performance, water-resistant underlay designed to provide superior protection and ventilation for pitched roofs. Measuring 1 meter in width and 25 meters in length, this roll offers extensive coverage for residential and commercial roofing projects alike. Engineered to act as the secondary line of defense beneath tiles or slates, it effectively shields the interior roof structure from wind-driven rain, snow, and dust while allowing internal moisture vapor to safely escape.
 
Constructed from durable, multi-layer spunbonded polypropylene, this breathable membrane combines exceptional tensile strength with a lightweight profile that makes handling and installation straightforward. It resists tearing around fixings and can withstand temporary exposure to direct sunlight during the construction phase without degrading. The material's balanced permeability prevents the accumulation of harmful condensation within the loft space, ensuring that the roof timbers remain dry and free from rot.
 
Playing a critical role in modern energy-efficient building design, this membrane helps maintain a stable internal climate while enhancing the overall weather-tightness of the property. It rolls out smoothly along the rafters, providing clear guidelines for secure stapling or counter-battening. Whether you are constructing a brand-new home extension or undertaking a complete roof overhaul, this 1m x 25m breathable membrane delivers reliable, trade-quality performance that meets regulatory standards and safeguards your roof for decades.
