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.
In bushfire prone areas flying embers cannot enter this space through the roof due to sarking protection. Moreover in heavy storms 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.
In summary, sarking can provide a long term environmental benefit to a new home, as well as additional protection against water damage and dust.
