Maintaining window above single story projection?

[leew2]

Just about to buy a house which has an upstairs window overlooking a sloping roof extension on the ground floor. The roof slope is perpendicular to the wall with the window. I was wondering what is the most practical/safe way of preparing and re-painting this window when it comes to it? I cannot see an easy way of getting to it with a ladder.
The window in question is a timber sash and case window.

Many thanks, lee.

You could unhinge it, repair/repaint as necessary ...allow to dry , and screw it back on

This style of roof ladder allows access over a low roof.https://www.google.co.uk/search?q=a...&ved=0ahUKEwjLjbzBrL3RAhUXc1AKHTZQANAQgjYIqgQ
