ᐅ Icicles forming on the balcony beneath the gutter near the bird protection screen?

Hi everyone,

I’ve been living in a new apartment for a week now. Since it feels more like a house, I thought this would be the right place to ask.

We’ve had temperatures around minus 4 degrees Celsius (25°F) day and night for several days. In the kitchen, there is a large glass sliding door—actually an entire wall—that leads out to the balcony. The kitchen is the only room that always stays quite cool; I don’t heat it.

For the past day, water has been dripping from the roof outside. This water immediately freezes on the balcony floor, creating a sheet of ice. On top of that, icicles are forming. See the pictures.

Can anyone tell me what might be causing this? The roof is a pitched roof, but above the entire apartment, there is an unheated and unventilated attic space without windows, which is also quite cool.

I’m wondering first where the water is coming from with a closed roof and second why it is liquid at minus 4 degrees Celsius (25°F).

Best regards,
Maddoc

Hello,
I have experienced before that a soil vent pipe, which is supposed to carry warm exhaust air from the restroom through the roof to the outside, was not properly connected and water was constantly dripping there. Do you have an extractor hood that might also be venting upwards? Maybe it’s simply snow that was blown between the roof tiles because of your low roof pitch and then gradually melted, dripping onto the underlayment and finding its way downward.

Hi, I don’t have a range hood. I’ve already been up in the attic. Everything there is dry. The gutters are frozen and also not wet. From the outside on the roof, there are no thawed spots visible. I just got worried because more and more water is running down and the icicles are getting longer... Help

Here are some pictures from just now..
