I can image milk jugs flying in a really strong wind… spilling milk everywhere I’ve seen wind blow things over a lot bigger/heavier.
My Flow Hive is tied down with 2 ropes onto pallets. (you would tie to your hive stand, etc).
My roof seems okay after being tied down quite strongly.
But, you can use some of the simple suggestions in the links above if you are handy and don’t want to put a heavy weight over the top of your roof.
