Hello everyone,
Our heating system was put into operation three weeks ago. Unfortunately, the roofers installed these black things (I don’t know the name, see photo Roof 2) in between. Because of this, a lot of moisture has accumulated, and now the beams are starting to develop mold.
Our construction manager said we should wait until everything dries out first and then treat the roof beams. In the long term, we don’t expect any negative effects.
What do you think about this?
Thanks and best regards

They should definitely be installed by the time water droplets regularly form on the underlay membrane.What could cause water droplets to regularly form on the underlay membrane? With a cold roof, this should never happen or be allowed to happen...
In the case of an unventilated roof (cold roof), there is a construction defect or a leak in the thermal envelope (it could be the attic ladder, penetrations, or similar).
If more warm air rises from below than is ventilated out at the top, the underlay membrane becomes damp or wet.
We check the underlay membrane every time we go up there;
for us, everything is dry, and there is always a noticeable airflow.
