2 means of egress?

hi everyone
would anyone tell me what can be the ’2 means of egress’? Does the access to the roof count as one egress?
b/c i am living in a 3 story-house,and the 2nd and 3rd floors are being converted into 2 SROs in each floor, and i found out that the whole 3 story-house does not even have a fire escape.
please help, thank you for reading
