Shingles in Building, small boards, nearly resembling, in shape and size, the staves of a common pail, but tapering regularly thinner and thinner from the broad to the narrow end. They were formerly used instead of tiles, for the covering of roofs, and are well adapted to those that are of a high pitch, but not so well for the modern low roofs. The steeples of many of our country churches are covered with shingles. The method of covering a building with shingles is extremely simple; at equal distances from the thin end there are inserted two stout wooden pegs, projecting on the inner side about two inches: by these pegs the shingles hang on pantile laths, nailed horizontally across the rafters, and at such distances, as to allow each row of shingles to lap over the next lower row by about half the length of a shingle. Sometimes, however, the roof is previously covered with boards, on which the shingles are nailed; but this method has the disadvantage of being far too expensive for common practice, especially in a country like ours, where oak is by no means plentiful, and what we have is wanted for purposes of greater national importance.
