Well, spray foam is a very standard way to insulate, should be the gold standard if you ask me. If that's what you are referring to. I assumed you meant spraying to sheeting instead of adding baffles.
To be honest I'm not sure if it's a newer standard or what (direct to sheeting on roof). All the houses I've had done we installed baffles for airflow. But the last garage I did with a mother-in-law suite above it they sprayed directly to the sheeting. And It's the same guy I've used for the last 15 years.
Now this is MN I'm talking about. All closed cell foam and a different climate.
