Your roommate is the one who cannot possess or control a firearm; there is no legal prohibition against you having one just because of his felony. However, your roommate should be concerned as possession of a firearm is tricky when it is in the same residence but not owned by the felon as the immediate ability to obtain control might be considered possession. The safest bet is for the roommate not to live there, but short of that, if the roommate has no access to the firearm, for example if it is locked up somewhere and the roommate does not have the key, that should be sufficient. There may be many legal defenses that could be argued if your roommate gets charged with possession of a weapon by a previous offender due to being in a residence with your firearm, but I am sure he would prefer not to be in that position as it is a felony charge.
