Did you just ask for a screenshot of something invisible?
In seriousness, though, it's probably not as high as you think. Humblemud's invisible ceiling is actually lower than the roof and you cannot get up into the weird little onion dome "attic". Even in Serenity Falls where you can get pretty high it won't let you stand on the roof - there's an invisible wall around that.
Having played in Grand Topal Hideaway I find this foolish, but that's how it is in most places right now.
I know you're on console and can't check yourself.
I purchased that home, how high are you planning to build?
I will try to check for you.

If it's anything like Forsaken Stronghold, you cannot build much higher than the highest point of the roof.
