Metal Roofs Are Trending Again
For a long time, tin roofs were the standard for most roofs around the world. They were used in Europe as well as the United States. They are perhaps most well-known in the United States as roofs for rural homes. Metal roofs were later replaced by asphalt shingles. Asphalt shingles are very affordable, easily repaired, and do a great job of covering a roof. However, they need to be replaced every decade or so. They also don’t protect as well as metal against fire damage or physical damage. For those reasons as well as aesthetic reasons, metal roofs are trending again for homeowners. 21st century metal roofs are not the same as their predecessors, though.
Titanium, Steel, and Copper Roofs
Depending on the market, tin used to be the most popular metal for roofs. Now, that market has been swallowed up by titanium, steel, and copper. Steel is very popular because it is a very strong metal that will last for a very long time with minimal upkeep. The drawback of steel is that it can be somewhat heavy. You need to have a very secure frame to support the weight of steel.
Those concerned about weight often choose titanium. Titanium is as strong as steel while being lighter in weight. It can also be made thinner than steel; however, titanium is more expensive.
Lastly, copper is a very popular material if expense is not your biggest concern. Copper is very desirable because it picks up a patina over time. The copper will darken and discolor, eventually picking up green tones.
Metal Roofs Last
The longevity of metal roofs is arguably the biggest selling point. A shingle roof will need to be replaced every ten years or so. Some new shingle technology can last about twenty years. Cedar shake roofs can last 15 to 30 years and are susceptible to certain kinds of wood rot. A metal roof can last over 100 years. There are metal roofs in parts of Europe that have been around since the 19th century.
With a ferrous metal such as steel, you have to watch for rust. That means treating the roof from time to time to keep rust from taking hold. Otherwise, the roof is fairly self-sustaining.
For all of these reasons, metal roofs are popular again. Lastly, metal roofs have a distinct sound when it rains that many people find very comforting, especially while they’re sleeping.
