Thanks!
I took that screenie after one of the patches a while back, in which apparently they made a weird change to how the large wooden containers position. For nearly 2 years, I had those containers flush against the west wall on the floor below, and it worked perfectly. I unlocked them to do some moving, and no matter what I tried, I could not re-place them flush against the western wall where they had previously been. I had to put them 1 tile east of the wall, and raise them with the deco tool to look like they were flush with the west wall...at which point to my horror I discovered they now poke through to desecrate my roof garden! (You can see the tops by the fountains in the pic).
That roof, which is on the first house I built in UO, has served me well, as I used it for all my pixel baking, and plant growing activities (at one time, the entire perimeter of the garden had growing plants in pots on shelves - those crates & chests on the northern wall had all my potions and plant resources/seeds stored in sorted color coded backpacks).
