By far the best option for painting a ceiling is using a roller on an extension pole. If you want to DIY，you'd better read the following words carefully, which may help you choose the right methord and way to paint.
Painting with a brush or roller while standing on a ladder is neck-straining work as well as arduous because it requires moving the ladder every few feet as you finish a section. In addition, using a roller on an extension pole gives you a better angle at which to work and prevents paint from dripping or splattering on you.
To begin, start at a corner and and roll slowly along the ceiling’s shorter dimension. Make an M or W shape across a 3-foot section and then reverse direction, filling in the unpainted areas as you go. Continue painting the ceiling in 3-foot sections, taking care to distribute the paint as evenly as possible and reloading the roller as needed.
When you have finished rolling the entire ceiling, run the roller from corner to corner around the perimeter of the ceiling. Do not load the roller with paint, and roll each edge in one continuous stroke.
