If it was my children I'd be a little concerned if they were all of sudden acting this way. My boys rarely go to their rooms to be alone if at all, they enjoy our company and we are always hanging out in the kitchen or living room together. The only time my oldest son goes to his room is when he is angry with me or upset about something at school and wants alone time, I give him that time and attempt to talk to him later about it.
Could she be going through something at school or with friends? I'd attempt to go in her room and tell her you're concerned. Ask her if there is something bothering her, tell her you love her and you're worried and want to help. It may not help at first but I would try that. I never came out of my room but I hated my father, couldn't stand him so I rarely spent time with my family, and there was nothing my mom could have done.
