I am pretty sure they don't but wanted to make sure. So lets say you had an ability that increases +1 on die rolls like a bloodline arcana. If you had an effect that did flat damage or healing (no die roll) but would otherwise satisify the requirements to trigger the +1 factor. Would you add the +1 once or not at all?

Better word choice and usage is helpful.
Some feats/effects only work with die rolls. Read the description as usually there is an effort to make it pretty clear. If there's no die roll then nothing gets added (if it is a requirement). Often damage dice and to hit rolls(d20) are seperate and the effect adds/increases one of; CL, DC, to hit roll, damage dice.
Really you answered your own question. 'giving +1 on die rolls' literally means to add one to the number rolled on the die. No roll means no +1.
