Hello, and welcome! Glad that you joined! Good luck with your flock. If the rooster crowing all night bother's you, maybe you could fall asleep by the music on the radio so that you won't hear the crowing?
Is it possible he is crowing all night because some predator is trying to get into the coop? If so, I have seen some people putting up a motion light outside the coop to scare off critters so your birds can sleep through the night.
