What is Sarking?
Roof sarking is a membrane that is fitted during tile or metal roof construction. The flexible membrane is usually installed under the battens to provide thermal insulation and to prevent water and dust penetration in the roof space.
Sarking is installed either under the main roof material in a building or sometimes between the wall cladding and wrap materials. Whether it is installed on your roof or between your wall cladding, they both serve the same purpose. The only main difference between the two types is the required regulations to follow under the Building Code of Australia.
Benefits Of Roof Sarking
- Help protect your property against thunderstorms and rain
- Can slow down the growth of mould due to the slowing of moisture getting into the property as sarking provides a vapour barrier. Due to this, it can also help reduce the risk of termites.
- Protects against dust from entering the roof cavity
- Some types of sarking allow a little vapour to get through, which reduces the buildup of condensation and moisture within the roof cavity.
- In bushfire prone areas flying embers cannot enter this space through the roof due to sarking protection.
- Sarking can also act to channel moisture into roof gutters and protect a home from water intrusion.
- Sarking not only acts as a protection against driving rain, but can also contribute to the energy efficiency of a home.
