How much longer will a metal roof last than common roofing like asphalt or wood shingle?

You can expect a metal roof to last at least 2 to 3 times longer than a regular roof. In general terms, count on a metal roof lasting 40 to 60 years and beyond.

Made of oil impregnated paper or fiberglass, asphalt begins to deteriorate as soon as you expose it to normal weather. A metal roof, however, will never decompose.

Other roofing materials like wood shingle, shake and tile have varying degrees of weather-related problems that lead to breakdown. Wood shingle and shake roofs often need replacement before twenty years. Concrete tile roofs can crack and warp in the freeze/thaw cycle of more northern climates.

All of the above roofing materials are well-outlasted by metal roofing, which retains its good looks and durability decade after decade after decade.
