A hip roof measuring 40 feet by 20 feet would require how much NET drip edge?

80 feet
100 feet
120 feet
140 feet

The correct answer is: 120 feet

To determine the amount of net drip edge required for a hip roof measuring 40 feet by 20 feet, it's important to consider the configuration of a hip roof. A hip roof features slopes on all sides, and for proper drainage, drip edges are placed along the eaves and rakes. For this specific roof, you have four sides to consider. The two longer sides measure 40 feet each, and the two shorter sides measure 20 feet each. When calculating the total length of the drip edge, you can add the lengths of all four sides together: - Length along the two 40-foot ridges: 2 x 40 feet = 80 feet - Length along the two 20-foot rakes: 2 x 20 feet = 40 feet Adding those together gives you a total of: 80 feet (from the longer sides) + 40 feet (from the shorter sides) = 120 feet. Thus, the correct amount of net drip edge needed for this hip roof is 120 feet. This ensures that the roof edges are properly protected and managed for water runoff, which is essential for the longevity and functionality of a roofing system.
