It's not wind doing this. The snow on the pitched roof does a slow
glacier sort of creep, and curls as it crawls over the edge, taking
the icicles with it.

That is not the mechanism that made them freeze on a curved path though.

Are the two pictures of the two sides of the house or one side from two
directions. Now I see what you're talking about; a totally different process
than I was assuming (and had seen before). Cool.

Both shots were from the same south-facing window, looking east and
west. Maybe the sun on the sloping roof makes the snow creep and curl.
I've looked at a lot of other houses in the neighborhood (all the
construction is very similar... draconian HOA rules) and I haven't
seen this anywhere else.

The icicles are clearly growing as their bases curl, resulting in the
curved shapes and branches. Tricky timing.

Neat planet we live on.
