Final answer:
True. Flat roofs typically have very little slope, making them more vulnerable to collapse under heavy snowfall, making it more vulnerable to collapse under heavy snowfall. Steeply pitched roofs, on the other hand, allow water and snow to slide off easily, reducing the risk of collapse.
Step-by-step explanation:
True. Flat roofs typically have very little slope, which means they are nearly horizontal. This lack of slope allows water or snow to accumulate on the roof, True.
