Is there a code that states mod bit is required when the pitch is zero and below? If so, where can I find it? Thank you

1/4 or maybe 1/8 might be the least pitch per code for any roofing...Not sure what zero pitch would be and there is no such thing as negative pitch....

Oh Well
There are choices beyond modified bitumen. Is the the job new construction or a re-roof? The 1/4" minimum slope rule does not apply to a re-roof.

If you have 0 they need to re-slope with crickets or something. Anything less than 2:12 requires a low slope roofing applications. R903 requires roof drainage. R904.3 requires materials to meet characteristics of roof and refers you to the code or ASTM standards for type of materials.
