How soon roof paint dries depends on several things.

Weather affects drying time. The paint will dry fast in hot, dry conditions, but it will take longer to dry in cold, humid conditions. Humidity might affect drying time. Excessive humidity can impede drying and degrade paint quality.

In rare circumstances, you may have to start over with new paint.

To achieve a good roof painting job, prepare.
