Where should you travel on Residential roofs?

• A. Valleys
• B. Hips
• C. Ridge Beams (Not found on Lightweight Construction)
• D. None of the above

Answer: (C)

The main idea is that when you need to move across a residential roof, you should travel along the ridge beam where it exists. The ridge beam runs along the peak and is designed to carry roof loads, providing a strong, continuous line for a firefighter to step on as you move from one area to another. Valleys and hips, where roof planes join, are weaker spots that carry concentrated loads and are more prone to decking failure or collapse under weight, making them dangerous to traverse. The note about ridge beams not being found on lightweight construction reminds us that not every roof has this structural member; when a ridge beam isn’t present, you can’t rely on it for travel and must adjust your path to safer structural members while avoiding weaker areas.
