Which tool is commonly used to create a ventilation hole in a flat roof when a saw is unavailable?

• A. Hand tools (punch or pry) to vent hole.
• B. A power drill.
• C. A sledgehammer.
• D. A chisel and hammer.

Answer: (A)

When you need to vent a flat roof and a saw isn’t available, using hand tools such as a punch to puncture the roofing membrane and a pry bar to widen and shape the opening is the fastest, most controllable method. The punch creates an initial entry quickly with minimal effort, and the pry tool lets you extend the opening to the required size without needing power tools. This approach gives you a usable vent hole rapidly, which is crucial for releasing heat and smoke. Other options—drilling, or using a sledgehammer or chisels—are slower, less practical for a large, continuous vent, or riskier for roof material and safety.
