What kind of roofing will you be using? The answer to THAT question will answer your question.
If you are using standard comp. roofing (3 tab or architectural), then 3/12 is the minimum. If the roof will metal, then you can go as flat as 1/2 in 12, assuming that this will meet the snow and wind loads of what and where you are building. Best check with your local bldg. dept. first.
