Phase issues usually only come in to play when you have 2 mics recording the same instrument (vocals, guitars, Snare, all the same), and the mics are very close to each other.
If this happens there is a “phase switch’ where you can reverse the phase on one of the mics. You can do this in UC Surface. (Little icon that looks like a circle with a line drawn through it).
You will know there is an issue because the recording will sound “thin”.
All that being said, this should NOT be an issue with room mic
