Another advantage of metal roofs to firefighters is that they are non combustible.

• A. Lightweight
• B. Easy to repair
• C. Non combustible
• D. No advantage

Answer: (C)

Noncombustibility is the main idea here. Metal roofs won’t ignite or contribute fuel to a fire, so they don’t feed flames the way wooden or other combustible roofing materials can. That means less rapid flame spread across the roof and a lower risk of the roof failing from burning material, which gives firefighters safer conditions and more time to work. It’s worth noting that while the metal itself doesn’t burn, other parts of the roof assembly (like wood decking or insulation) can still burn; the key benefit is that the roofing surface itself doesn’t add fuel to the fire. The other options describe different properties (weight, ease of repair, or a blanket statement of no advantage) that don’t directly capture why metal roofs are advantageous to firefighting in the way noncombustibility does.
