Generated explanation

The top-view drawing shows overlapping cedar roof shingle courses with staggered joints and two fasteners per shingle. Fasteners are located 3/4 to 1 inch from the shingle edges and 1-1/2 to 2 inches above the butt line of the next course, with 1/4 to 3/8 inch spacing between shingles. Adjacent courses require at least 1-1/2 inches of joint offset, and no two joints should align within any three courses; a knot must also be offset at least 1-1/2 inches from the joint between shingles above. Flat-grain shingles are limited to 8 inches in width. A table specifies exposures of 5, 5½, and 7½ inches for #1 grade shingles of 16, 18, and 24 inches in length, respectively, on roof slopes of 4/12 and up.
