Metal is an ideal material for roofs due to its durability and its recyclability, resistance to mildew and algae growth, its low weight, its wind resistance and its fire protection. I recently wrote about standing seam roofs, which are made of metal and are becoming increasingly popular. Another popular metal roofing is metal shingles, especially for those who prefer a shingle look. While they may be more expensive to start with, they offer the look of natural materials but without the maintenance costs or other risks associated with many other materials, as well as potentially lower insurance premiums.
Metal shingles are formed with an air space between the metal and the roof deck. This air space acts as a thermal break to stop the conductive flow of heat from the roof surface to the attic. (Think about what the dead air space between two layers of glass in a thermal window does.) Tests by the Florida Solar Energy Center found that high-reflectivity brown metal shingles reduced heat gain by 40.9% compared to standard asphalt shingles. This is all due to the air space between the metal and the roof terrace. In cold climates, like any other tile, the ceiling must be insulated.

Steel metal shingles are made of steel with a zinc or zinc and aluminum metal coating on top of the carbon steel. This corrosion-resistant metal coating protects the steel from rust. In addition to the coating, manufacturers typically have a paint or aggregate coating for additional protection. Many metal shingles are also made from aluminum and copper, which are naturally rustproof metals.

Metal has been used as a roofing material for many years. Thomas Jefferson worked with metal clapboards for his Monticello home and other buildings. Metal shingles have also been used by retail chains such as IHOP and Dunkin ‘Donuts for many years. According to the Metal Roofing Alliance. The market share of residential metals for metal roofs is currently 14%.
The oldest commercially available metal shingles were developed by Kaiser Aluminum in 1959; Their line of products was later acquired by Isaiah Industries, Inc. in 1980. Most of the other metal roofing products available today were invented in 1980 or later.

Recent developments in the metal shingle roof industry have made them increasingly popular. There are products on the market that are stamped to look like standard clapboard, slate, wood shakes, and tile. One of the recent advances in metal shingle technology has been painting, which is varied to allow the products to have multi-colored surfaces that look even more like slate, wood, asphalt shingles, etc.
