Feral cat on neighbors roof and doesn't want to come down. Does anyone have any insight?

My mom alerted me to a cat that is on the neighbors roof and got pretty violent when it was attempted to be removed by a guy that is remodeling the house. He gave up since he was scared of the cat. It appears the cat has been up there for two days that we know of. It howls when we get close.

The police have been called and they don’t care.

It is 85º here so the cat has been cooking on the roof with little shade.

I placed food and water up there (two things of water to be precise since one is on the other slope) and a few long boards so the cat can walk down.

Here is the best part. My cat followed me while I was doing this and walked up the plank. Ate some of the food and walked back down.

I guess my question is how do I get this fucking cat down without getting rabies?
