I zoomed this picture and it looks like the service drop was L/N/L across the edge of the roof and the Line insulator closest to the peak broke.
The white wire looping up over the roof looks like it might be TV cable. There is what looks like a 4 way splitter next to the service raceway on the gable end.
I am wondering if this 3 pack of insulators was originally on the fascia and the siding guy moved it when they did the re-skin.
I am sure we have all seen siding guys do strange stuff.
