Multiple Choice

In an opposing saw configuration, which sequence of components is used?

Explanation:
In this setup, you grow the ventilation opening by alternating between preparing the edge with a hook and cutting with the saw on opposite sides. Start by using the hook to free and lift the roofing edge, then run the saw to begin the cut. Next, move to the opposite side: again use the hook to expose that edge and then the saw to extend the cut. This hook–saw–hook–saw sequence on opposing sides creates the opening in a controlled, balanced way, reducing the risk of uncontrolled collapse and allowing rapid venting. Using two hooks in a row or two saws in a row would not advance the opening as effectively or safely in this pattern.
