Attaching ledger to weatherboard house

I'm attempting to build my first deck. Fingers crossed.

How do I attach the ledger to my weatherboard house? I can bolt it straight on to the bearer of the house but the weather boards are at a slant which will tilt my ledger. Do I just use a series of two bolts placed vertically and a number of washers to square the ledger?

You could use washers or some sort of packer such as timber, malthoid or you can get proprietry plastic ones.
