More and more people are turning to metal roofs. In most cases, metal roofs can last up to 20 years, and sometimes they can last as long as 50 years. Easily shrugging off the effects of rain, wind, mildew, insects and rot, which plague other types of roofs, metal is a great choice of roofing material. Metal roofs are also much lighter than traditional tile roofs. In addition, metal roofs are easier to install. Since they come commonly in large sheets of connected panels, they can be installed faster than other types of roofs. You can expect to shave a day or two off the time of a traditional roof installation by opting for metal roofs.
