The high winds last night resulted in this sight in the morning

It appears the anchor point is attached to the roof flashing instead of the house itself. I've managed to push it back into place for now but really think the anchor point should be moved to something more solid so it doesn't happen again. Do I call Chorus or ISP? The original install was over two years ago with previous house owner. I could probably move the anchor point myself but worried that if I break it somehow then it'll be my fault and then I'll be charged for them to come out and fix it.
