I do hope I'm in the right forum here....if not please forgive me!
Can I ask for some advice about (safely) putting a 'wet set' inflatable pool on the roof top of our village house in Sai Kung?

The house is about 4-5 yrs old and the area where I'm hoping to place the pool does have some support from interior walls beneath it.
Last summer we had the 12ft 'Wet Set' inflatable pool up there and the roof didn't cave in! However I'm planning to replace it this year (the old one got punctured) and somebody mentioned that weight-wise it might not have been safe.

Does anybody have any advice about this?
