Whether you’re a roofing professional or a hands-on homeowner, the Permavent Black Breather Membrane (1m x 50m – Pack of 10) gives you the strength and protection you need to finish the job right.
Harsh weather can cause major damage. Without proper roof protection, moisture creeps in, insulation weakens, and structures rot. You don’t want to fix leaks after they happen—you want to prevent them before they start. That’s where Permavent steps in.
Builders across the UK trust Permavent for its proven reliability and superior performance. Each roll delivers excellent water resistance while allowing moisture inside the roof to escape. This creates a breathable, energy-efficient layer that keeps homes dry and warm, no matter the weather.
With 1m x 50m per roll, and 10 rolls per pack, you cover large areas fast and cut down on waste. You don’t need special tools. You don’t need hours of prep. Just roll it out and secure it in place. It works with both cold and warm roof constructions, giving you complete flexibility.
