Hello, we are now experiencing our first winter in the house.
The humidity level is always around 60%, sometimes even higher.
The exterior plaster was completed last week.
Moisture also accumulates on the roof windows.

Could it be that the masonry is still damp?
It’s a brick house without mechanical ventilation.

Regards, Patrick

Well, enjoy your moldy place. At least you’re only damaging your own building structure and not a landlord’s.

I don’t have the time or colored pencils to draw it out.

I asked if it is normal for it to still be relatively damp.
All I can do is ventilate; I can’t tear off the roof.

It’s not about why it’s molding, because it isn’t yet, and I want to prevent it from getting to that point in the first place.

Yes, that’s exactly what we’re saying: it is normal if you don’t ventilate regularly, but it’s not good!
-> That’s why we recommend ventilating before you have to ask the question, “…so, how do we get rid of the moisture?”

In our cold attic, the humidity is at 70% with a temperature of about 2°C (36°F). I just checked the rafters and the rest of the structure using a spotlight. I couldn't find anything unusual. Is this normal? How is it in your homes?

It is normal; the absolute humidity of the air is very, very low.

Maybe a construction dryer would help as well?

In our unheated attic (cold roof), the humidity is 70% at around 2°C (36°F). I just went upstairs and checked the rafters with a spotlight but didn’t find anything unusual. Is this normal? How is it in your cases?

Completely normal for a cold roof; we currently have 5°C (41°F) and 67 percent humidity.
