Hello everyone,

We are approaching the end of the construction phase. Yesterday, when the tiler wanted to start tiling the bathroom on the top floor, I noticed a damp spot in the corner as shown in the picture. According to the architect, it could be condensation. The roofer is coming tomorrow to inspect the roof again, but he said it would be much worse if the roof were leaking.

Construction started on 01.05.2017
Screed cured for 9 weeks
I don’t remember exactly how long the interior plaster took, but it was longer than the screed

Doesn't it need to be glued somewhere?

It is glued. As far as I know, however, this is only allowed if the membrane is secured with a counter batten.

Oh, that’s the joint to the next house. You can easily make a mistake with the roofing there.
A counter batten isn’t necessary in that area; in the photo, it initially looks correct.
