What are breathable roof membranes?

Roof membranes, also known as roofing underlay, are large sheets of material that are used to add an extra layer of protection to your roof, preventing water ingress within your home. There are breathable and non-permeable membranes. Breather roof membranes are water resistant, but allow the movement of air through the membrane. 

Why use a breathable roof membrane?

Breathable roof membranes have been designed to combat the issue of condensation. Condensation can be caused by small things, as simple as cooking without a lid, drying clothes and even breathing, and condensation build up over time can lead to greater issues. These issues include damp, mould and even rotting of timber structural frames which can cause serious problems and can put the whole building at risk.

Breathable membranes allow moisture to move between the layer in the form of water vapour. In doing so, this reduces the risk of build up of condensation, as the water vapour is able to leave the roof space. 

Breather membranes were designed as an alternative to tile vents – breather membranes allow ventilation to occur and water vapour to pass through, removing the need to install a number of tile vents along the roof, saving time, money and labour. However, we’d still advise having another form of ventilation in case the breather membrane is not enough, or excess moisture is produced.

Where are breathable roof membranes installed?

Breathable roof membranes are generally installed on the cold side of insulation in the roof structure – ie the side closest to the external area. Breathable roofing felt, also known as breathable roof membranes, can be used within both walls and roof structures, particularly when the external roof or wall materials are not completely watertight. The breathable roofing membrane will ensure that no moisture will pass further through into the building, if it has already managed to pass through the external materials, whilst still preventing condensation from building up, due to the breathable feature. 

If no breathable membrane is installed, water vapour may pass through the external material onto the insulation layer or even further into the structure, and then it would create condensation. This condensation would then build up, or drip down the structure, leading to damp, rot and mould.

Other benefits of installing breather membranes

Breather membranes can also be used as short term protection during construction or renovation work – they are snow, wind, dust and water resistant, so are a great way of keeping the overall structure of the building safe and dry. 

Additionally, breathable membranes can be used to add an extra insulating layer within the building, retaining heat more easily and reducing energy bills. As there is an increasing drive for sustainable and energy efficient buildings to reduce environmental impacts, insulation is becoming a key focus within the construction industry, and small changes like including a breather membrane can have a large impact.
