Parallel Cut is also known as what?

• A. Top Cut
• B. Base Cut
• C. Side Cut
• D. Back Cut

Answer: (C)

In roof ventilation terminology, how a cut runs often defines its name. A parallel cut means the cut line runs along the side direction of the roof—horizontally along the edge rather than toward the peak or across from front to back. That sideward orientation is why it’s known as a side cut. The other terms describe different orientations: a top cut goes toward the roof’s apex, a base cut sits near the eaves, and a back cut is taken from the opposite side to create an opening. So, a parallel cut is best described as a side cut because the cut runs parallel to the side edge of the roof.
