When planning hole location on a roof, what structural factor is important?

• A. Avoiding cutting near trusses to protect roof integrity.
• B. Proximity to windows.
• C. Random selection.
• D. The color of the roof.

Answer: (D)

When planning a roof hole for vertical ventilation, protecting the roof’s structural system is essential. Trusses are the primary load-bearing elements that transfer weight from the roof to the walls, so cutting near or through a truss can weaken the roof structure, disrupt load paths, and increase the chance of collapse or sagging as crews work overhead. The safest approach is to place the hole away from truss members and in a section where the decking can be cut without compromising supports. Proximity to windows, random selection, or the roof’s color don’t influence structural integrity and aren’t relevant factors in this planning.
