First Welcome to the Forums Tyler
Next if you did not make any software adjustments it really should not be a software issue. Rooted and Stock rom should be just as stable as completely stock. The only thing that can be is some app with permissions doing weird things but never heard of putting the phone into bootloop.
The first thing to try is to do emergency firmware recovery from Kies software - note you will need the S/N from under the battery so grab that one before you start. It is in the drop down menus in Kies - try that and hopefully it works for you. If not the final option is to call Samsung and tell them that your phone blew up and omit the details of root.
