When installing new flat roofs for garages or replacing your property’s pitched roof, it takes expert skill. An experienced roofing company will understand how each element needs to come together to ensure the roof is structurally sound, well insulated and waterproof, and this could include a breathable membrane layer. Here’s everything you need to know.
What Is a Roof Membrane?
Roofing membranes play a vital role in preventing water ingress through your roof. However, there are both breathable and non-breathable products on the market.
A breathable roof membrane ensures that this vital layer keeps your new roof as ventilated as possible, reducing issues caused by a build-up of condensation. The structure of the layer allows any moisture trapped in the cavities to escape, thanks to its water vapour permeability. Good roof ventilation is essential in reducing interior damp, mildew and mould developing. Breathable membranes also provide enhanced wind resistance to restrict the movement of air through the wall space.
However, your roofer may advise a non-breathable membrane is the better option if you have an effective ventilated pitched roof system already in place.
Where Is a Roofing Membrane Fitted?
Roofing membranes are lightweight in nature, so they don’t add a lot of extra weight or pressure to your roof structure. Where a roof membrane is fitted will depend on the style of roof, materials chosen (to be laid over the top of the membrane) and the experience of your roofing contractor. Your roofer may also have several different membrane options for you, depending on your roof’s characteristics and the weather conditions it’s likely to face.
Roof membranes are often installed over the top of features such as joists and rafters, but they can also be laid under tiles and battens. Your roofer will usually choose a membrane material that’s ideal for the roof structure it’s fitted to, easily connecting to roof battens and other features.
Benefits of Roof Membranes
The main benefit of installing a membrane is to improve how weatherproof the roof is.
When you replace or upgrade roofing, the modern material you choose should do most of the work to keep water out of your property, but the membrane will provide even more protection. This gives you peace of mind that there is an additional barrier present should your roof lose a tile.
As well as being waterproof, most roof membranes are also highly resistant to UV light, meaning they can withstand extreme weather conditions such as the high temperatures faced in the summer.
Your roofing contractor should use a high-quality membrane material that will last for many years to come, so it won’t tear or rip over time.
