How many squares of roofing and how many pieces of ridge shingles are needed for the roof in Figure 15.20? The slope of the roof is 5:12 and the exposure is 5 inches wide. From Problem 19, the area of the roof is 1,200 sf or 12.00 sq.
What will be an ideal response?
Starter course = 38?8? of eave per side × 2 sides × 5? / 12 in per ft = 33 sf = 0.33 squares
Squares of roofing = 12.00 squares + 0.33 squares = 12.33 squares
Ridge shingles = 38?8? × 12 in per ft / 5? per shingle = 93 pieces
