The History of Metal Roofing, from Copper and Lead to Commercial Steel
The roof is one of the most important factors in any building. Without a roof to protect the building and its inhabitants from wind and rain, the entire structure would be useless, and might even fall apart.
Roofs used to be made of wood and slate until metals took over in the mid-19th century.
In America, metal roofing primarily took off in the 19th century. Before that, lead and copper were sometimes used to cover roof surfaces if the roof’s pitch or shape did not work for wood, tile, or slate.
Sheet iron was manufactured in America by Robert Morris, who helped finance the Revolutionary War, in the 1790s.
The method for corrugating iron was patented in 1829 in England. This made the sheets of metal stiffer and allowed greater span over lighter framework and reduced labor and time to install.
In 1837, French builders developed the idea of galvanizing the base metal with zinc to protect from rust, and by the 1850s, this material was often used on post offices, train sheds, factories, and more. This material remains widely used even today.
In the early 1900s, stamped sheet metal roof tiles made to simulate clay was popular, and large steel roofing panels were particularly helpful for industrial and agricultural buildings.
Metal is one of the most popular materials for commercial roofing today. There are multiple types of metals that can be used for roofing, including silicon-coated steel, corrugated galvanized steel, stainless steel, stone-coated steel, and more. To prevent rusting from sun exposure, these roofing materials can have surfacing layers applied to protect against damage.
