The structures are calculated by vertical connections.
The game counts how many pieces between your next piece, and the ground. So longer pieces work better, and adding more pieces actually can subtract from your building strength (if attached below the next piece)

This is true, I've solved roof integrity problems be evaluating the number of connections to my closest grounded (blue) piece. (when I did not yet have access to more advanced pieces like stone or wood/iron)

that said using a tree or an existing stone structure would absolutely work as a flying buttress as it would give you an elevated ground (blue) connection.
