What can I say? There are nice things on roofs, and I don’t mean shingles.

Now, anyone can put together a simple arrow weathervane, but the more artistic the vane, the more engineering needs to go into it. To catch the wind properly, the vane’s rear portion needs to have a broader surface than the front, but to swing freely, the (smaller) front must weigh approximately as much as the back. What does this mean, exactly? It means you can’t just throw any old sculpture you like onto a roof and call it a weathervane.
