Although its not a proper fix i managed to get through this by turning the roof into a room first and vacuuming it before getting rid of the walls. you need to place windows and another roof on top for this to work for some reason otherwise they just keep cleaning without any results and have to make sure the stairs to the roof is from the inside of the house or else they don't even start cleaning.
This is still an issue, obviously it makes no sense having to vacuum a roof because it's a roof.
Even the game agrees as it won't let you vacuum the roof, game just cancels the vacuum action.
So can we get rid of the angry/upset dust moodlets associated with any roof area that game knows is a roof and can't be vacuumed, thanks.
