Copper in ArchitectureFact 6 of 17
Various estimates put the lifespan of a copper roof at more than 100 years, while asphalt shingles - the most commonly used roofing material in America - are said to last 15-30 years, on average. This makes copper one of the most cost-effective roofing materials on the market. The reason for copper's longevity is the natural patina it develops with age that serves as a protective shell when the metal is exposed to the elements.
