How much longer will a metal roof last than asphalt or wood shingle?
A metal roof will last at least 2-3 times longer than a regular roof. An asphalt roof needs re-roofing every 12-20 years, while a metal roof will last 40 years and beyond. Other roofing materials begin to decompose as soon as they are exposed to the elements. A metal roof will never decompose and will hold its good looks for decades. Most metal roofs come with up to a 50 year warranty. Metal roofs have actually lasted over 100 years in many instances.
