Cat on roof for almost 2 months☹️Help please!

A stray got on the rooftop and can't get down. She has been through 5 thunderstorms without any shelter.. and apt complex won't get her down, in fact I think they want her to die because I found someone with a ladder and complex told us we couldn't get her down cuz they are liable if we get injuries. So now I need a ladder that extends. And I'm gonna do this at night cuz she doesn't deserve this cruelty. ANYBODY GOT A LADDER I CAN PLEASE USE? I'll do all the work to get her down. We have called everyone to assist... But they don't care or don't have the ladder to make it happen. Please Anyone, I want to keep her too, if I can get her down before she dies. My mom and I are out of ideas and resources. NOBODY is coming to save her. I'm begging.
