Hi dsa39,
I think mine reads the same. I think it means they will apply sarking 'underneath' the roof tiles, as opposed to only on the lower roof. For peace of mind your sales consultant should be able to confirm
Hi manhattan37 the diagram actually has arrows only pointing to the single story roof of our split level home not the double. I will def check as this is a biggie for us as we are bush fire rated. Ill keep you posted Cheers
