Metal roofing, as the name suggests are made up of metals like, aluminum, copper, steel, tin, and zinc. They come in the form of corrugated metals, slate roofs, or tile roofs. Having a metal sheet up on the roof can prove advantageous if you are looking for a long term investment because of its longer life span, sturdiness, low maintenance, and great return on investment. It is a one time investment which can last up to 50-80 years depending upon the metal type.
