So you look at risk and reward.
You can go higher at the house if you go into the gutter height with the soffets removed the rafters are hung off the house.
The problem here is the waterproofing joint between new and old as the snow will slode down the old but stop on the low slope and water could back up there.
You can build with posts above the posts on the deck.
With out the footing we have an unknown, it may never heave but if it moves it not only works the joint between house and rafters but it work the roofing joint too.
I am not say you shouldn't or you can't I just like it when we understand what could go wrong. So if you want to build it I will still help where I can.
