ᐅ Carport roof drips during transitional weather conditions

Hi,

I have the following problem:

My carport is made of aluminum panels with a metal roof.
When it gets colder outside, and the sun shines on the roof, the inside of the roof starts to drip.
Not the inside roof surface itself, but the crossbeams.
What options are there to cover these beams so they don’t constantly leave these "unsightly" water drops on my car?
The carport is well ventilated and covered on one side with a "permeable" cladding.

Are all sides probably closed or at least nearly closed?

No. Only the right "north side" is somewhat enclosed, but not completely. The west side is closed off by the adjoining room.

Then either my ultrasonic device is broken, or the marten has already gotten used to it. I always find paw prints on the roof despite using the ultrasonic device. Could you possibly tell me which type of marten repellent you use?

mine is this one:

Hello,

I have now ordered a few pieces of this fleece.
When the weather outside becomes more pleasant again, I might install them then....
