HOW METAL SHINGLES ARE MADE.
Shingles made from wood have been common all over the world for ages. Their particular form has remained unchanged because many years’ experience has proven it to be the most durable and surest safe-guard against storms. What is true of wood for roof covering is equally true of metal for the same purpose. The first metal roofing made in America was tin sheets, laid shingle fashion, the overlapped edges of which covered the nail heads which were used to fasten them to the roof boards. Many of these old-fashioned metal (tin plate) roofs are yet in existence that were covered over one hundred years ago. The writer covered several houses in 1849 in this manner, which are in good condition now. The reason why this style of metal roofing was not common was its expense. On [page 16] we give reasons why it would be more durable than the ordinary mode of laying tin roofing.
