Determine the purchase quantity of 2 × 6 rafters needed for the roof in Figure 14.67. The slope of the roof is 4:12.
What will be an ideal response?
From Figure 14-48, the slope length factor is 1.055.
Run = 28? / 2 = 14?
Length = 14? × 1.055 = 14.77? – Use 16? rafters
Number of spaces = 34? × 0.5 spaces per foot = 17 spaces
Use 18 for each half of the roof for a total of 36.
