In IRC 2015, it states valleys must be designed as beams if the pitch is less than 3:12. I have always designed them as beams regardless of pitch. Am I being too conservative? I see why a ridge board and a hip rafter that has rafters that set on a wall may not need to be designed as a beam but it also seems to me that if the hip supports rafters that also run to a valley, they too would need to be designed as a beam regardless of pitch.
