The illustration shows a cutaway cedar shake roof assembly over plywood sheathing, with overlapping shake courses and felt interlay over the top of each course. Eave protection extends at least 36 inches up the roof beneath a 15-inch starter course. The shakes project 1-1/2 inches beyond the eaves and edges. A table specifies exposures for #1 grade shakes on slopes of 4/12 and up: 7-1/2 inches for 18-inch shakes and 10 inches for 24-inch shakes. The drawing directs the reader to a separate illustration for nailing and shake placement details.
