You must first know what the environment is on the roof of your house. If it is a wooden board, you can use a screwdriver at home. If it is smallpox, you need to use a hand drill. If it is wall or cement, you need to use a professional impact drill. Screws are simple and common.

I read your supplement. There are hooks on the ceiling. How wide curtains do you want to install? If the distance between the two hooks is less than the length and you don't want to drill holes in the roof, just tie the ends of the curtain track to the two hooks. The track is not expensive for a few dollars a meter. You can buy one and try it first.
