In a 6:12 roof with eaves extending 30 horizontal inches from the eave line, what should be the width of ice dam protection?

A 30 horizontal inches
B 48 horizontal inches
C 54 horizontal inches
D 60 horizontal inches

The correct answer is: C 54 horizontal inches

In roofing, ice dam protection is essential, especially in regions susceptible to snow and ice. The width of ice dam protection is typically determined by the extent of eave projections and the slope of the roof. In this scenario, a 6:12 pitch indicates a relatively steep roof, which influences how quickly snow will slide off, but there is still a risk of ice accumulation at the eaves. For a roof with eaves extending 30 horizontal inches, the width of ice dam protection should be greater than the eave projection to effectively manage potential ice buildup. A common guideline is to have ice dam protection extend at least 24 inches inside the warm wall line. Therefore, adding the 30 inches of eave projection to the 24 inches required results in a total of 54 horizontal inches of ice dam protection. The correct choice reflects this requirement, as it allows for sufficient coverage to prevent moisture intrusion due to ice dams that could form during winter weather conditions.
