Shingle is a corruption of german schindle schindel meaning a roofing slate. With white cedar shingles also make sure that two joints do not align if separated by only one course. The first course is the starter course and the last being a ridge course or ridge slates. Shingles are laid in courses usually with each shingle offset from its neighbors.

Also offset joints in successive shake or shingle courses by at least 1 1 2 inches as shown in figure 1 15. A roof that isn t installed precisely the way it was intended can be both unattractive and incapable of standing up to extreme weather conditions. Treat knots and other defects like an edge and offset adjacent courses at least 1 1 2 inches. Many pros shingle in a vertical line up the roof because it s much faster.

Occasionally for added ornamentation roofers would insert a few parallel courses of scalloped or beveled tiles into a roof of predominantly rectangular slate tiles. Old roofs of slate or wood were typically constructed of individual rectangular pieces offset and overlapped to shed water.
