New flat roof - Attic is dripping

Hello, we had our flat roof renovated in the spring. It has a slight slope towards the street side, water drains well, and hardly any puddles form. At the back is our living room. What I noticed is that water often drips from the parapet during rain or dew. So it seems the parapet has no inclination towards the roof - small puddles also form on the covering. Is this professionally done? Unfortunately, I do not have a better picture.

Attached is the picture. Unfortunately, I don't have a better one..
