Flat roof without slope okay? Water will then stand on it, right?

Hello everyone, just a quick feedback. Completion of the renovation, moving in, various defect repairs, family growth, ... there was quite a lot to do, which is why I am only getting back to you now. Thank you for your responses!

First of all, no agreement has yet been reached with the architect because all his remaining trades first had to complete their work. You wanted to know how the flat roof came about. Originally, a slope of 2% was planned. Higher was somehow not possible because the parapet was not sufficient. I don’t know why, since the architect initially had complete planning freedom. When the extension was in the timber shell stage, I was told during a site meeting, among other things (you always discuss a lot at such meetings), that smaller water puddles would always remain on the roof due to the joints of the bitumen membranes. In a further conversation, possibilities were discussed as to how one could lay terrace decking or gravel on the roof, since from the first floor you can see exactly the unsightly black roof. And suddenly, without new drawings or explicit approval, or notes about possible increased maintenance effort, the roof and the water level on it were fixed...

Does the roof have to be greened? If yes, no problem with 0 degrees, provided the load has been calculated correctly.

Our storage room roof was also greened because we had standing water. But it was a small area. It is a matter of structural engineering and cost. The soil absorbs the water

I would neither wait until everything is finished nor immediately shoot down the architect.

Ask neutrally how the difference from the plan came about. Vague answer? Keep asking (when, which meeting, who was present, is there a protocol...). If it turns out that it "somehow happened," then demand a solution without assigning blame that allows the water to drain as planned. If someone gives reasons why that is not possible – don’t argue, but steer the other person back to solution-oriented thinking. "What would be an alternative?" "What other solution would work?"

This way, you get closer to the goal of having the roof with a slope without additional costs and disputes.
