Why use breather membrane in roofing?

Breather membrane gives roofing the best chance of longevity, keeping moisture and condensation to a minimum. Installing it can also help to reduce heat loss through the roof space by up to 25%, which can improve energy ratings.

Our range of breather membranes have been carefully selected to deliver an eco-friendly solution to homeowners looking at building better sustainable homes. Save money on ventilation products and eliminate thermal bridges with a good quality, long-lasting breather membrane from PermaRoofUK.

How to choose the right membrane for a new build

It is essential that the building regulations are carefully followed when you’re working on a new build. This means that you’ll need to select your products based on a range of factors, such as wind lift, roof design, usage and much more. Some UK breather membrane manufacturers categorise by region.

Frequently asked questions about breather membrane


Breather membranes are not suitable for flat roofing. A VCL or insulating board offers a better approach for flat roof projects. We stock Resista AK PIR insulation boards, ideal for EPDM flat roofing systems.

Condensation can lead to a range of issues and cause damage in the structure of the roof over time:

  • Rotting timbers
  • Lost thermal performance
  • Mould

While a straightforward process, installing breather membrane properly is important to avoid issues like thermal bridging and heat loss. There are minimum requirements in the building regulations for air leakage and other considerations, especially for new build projects.

Seek professional advice if you’re unsure about installing to regulations.
