How many rafters are needed for a gable roof that is 32 feet long with rafters spaced 16 inches on center?

To determine the number of rafters needed for a gable roof that is 32 feet long, with rafters spaced 16 inches on center, we first need to convert the roof's length from feet to inches. Since there are 12 inches in a foot, 32 feet converts to 32 × 12, which equals 384 inches.

Next, we need to calculate the spacing of the rafters. With rafters placed 16 inches apart, we can find out how many spaces fit into the total length of 384 inches. The number of spaces can be calculated by dividing the total length by the spacing:

384 inches ÷ 16 inches = 24.

This calculation shows that there are 24 spaces between the rafters. However, we must remember that the number of rafters is always one more than the number of spaces. Thus, we add one more for the first rafter at the beginning of the run, resulting in:

24 spaces + 1 = 25 rafters.

However, since we previously calculated the number of rafters directly from the total length, it is important to note that if we consider the actual physical structure, the range requires rounding or assessing the total coverage.

Therefore, 24
