If we assume its something caused by the powerlines.
What would help is to do this (wear gloves). caulk the joint then put a screw in the face and draw the fascia trim tight together. This will do two things. It will draw the two pieces together making a connection that wont arc and it will also be more weather tight.
It wont solve any other issues.
Did your electrician look at grounding at your main? Inspect the incoming power lines? Give any opinions on the transformer or utility service?
I would call the utility, tell them there are issues.
