Simple RAW for 5e V: The Disadvantage Strikes Back

[The Shoeless]

Q61 What constitutes as a weapon damage roll?

A barbarian attacking and hitting with a weapon that does 1 damage (e.g. a torch) can't add their strength bonus or rage damage bonus as those are only added to damage rolls. Would that barbarian choose the zealot path to add 1d6+1/2 barbarian level extra radiant damage, would they have a damage roll now?

Q62 If yes, would the damage added via strength and rage damage bonus added as fire damage (the torch) or radiant damage (the roll)?
