What is Roof Sarking?


Roof Sarking is a layer of laminated aluminium material that is installed by your builder underneath the roof of your new home and it looks something like this:



Roof sarking is mandatory in all BAL 12.5 to 40 rated lots to meet the bushfire ember attack requirements under Australian Standard 3959 Construction of Buildings in Bush Fire Prone Areas. For more information on Bushfire Attack Levels (BAL) check out our article, ‘What is a BAL?’. 


Most builders will often charge extra for roof sarking as it is not included in their base price. So it’s a good idea to ask your builder upfront before you sign a building contract.


Benefits of Roof Sarking


Roof sarking has a number of benefits which will improve the comfort and efficiency of your new home. Some of these benefits include:


1. Improves thermal performance by shielding your new home from up to 97% of radiant heat.


2. Protects the frame of your new home from adverse weather during construction.


3. Provides a secondary form of bushfire ember protection for the roof of your new home.


4. Reduces the amount of dust and storm driven rain from entering your roof cavity. This will protect your new home from mould growth and ceiling staining/damage.


Remember, unlike carpets and fittings, which can be installed at any time, you can only install roof sarking whilst your new home is being built. So, make sure you ask your builder whether roof sarking is included in your new home.
