The best option to get outside for awhile would be the roof.
How about upstairs?
Maybe the access to the roof is closed down.
Maybe it would help if you would get access to the blueprints of the house. ?
Get into the safe.
Look at them, then!
There is a weak spot in the bedroom now that you can interact with. ? It is the wet looking spot in the roof. Break through it.
You really have to look at the blueprints, first.
Now, climb up there.
