Can plumbing vents run horizontally or at a very shallow angle?

I have a main stack that I would like to send horizontally or at a very slight slope in order to clear roof space for solar panels. Currently the pipe goes vertically through the roof on the exterior of the building. Could I send the stack diagonally along the exterior of the house to a different area of the roof where it won't interfere with the panels? Would this be against code? Thanks in advance submitted by /u/DriveSideOut [link] [comments]
