For starters I don't think it is a good idea to allow remote root logins
There are several ways to do what you want.
A few options

If you only need the root users to login, set the firewall to only allow 
ssh from specific IPs. Set a user that can ssh and either configure sudo 
or allow user to su.

That sounds like something you could do with a regular user + sudo.

Yet another approach, you can turn on  to allow connections with keys 
only. No password authentication. Then enable root.. or better another ID 
which can su or sudo the commands you need.
