Is a terrace gutter in front of the terrace door necessary with a 1.65m roof?

Hello everyone,

I have two balconies and a terrace on the south side. The balconies and terrace are each covered by 1.65m.
The balconies and terraces are permanently enclosed. The terrace doors are flush on the outside. There is no threshold and no terrace gutter yet.

Is it necessary to install a terrace gutter with a roofing of 1.65m?

Formal answer or realistic and pragmatic answer desired?

Pragmatically, I would say that I don't need it. Even after the century flood here in the Eifel, the terrace/balcony remained dry 1m away from the outer wall. Since the modernization is financed through a loan and the bank will send an appraiser, I fear that this person will insist on a terrace drain and a minimum threshold of 2cm.

Never. I have never experienced anything like that.

No, that will NEVER happen. Don't worry.
