How much longer will a Classic Products roof last over common roofing such as asphalt or wood shingles?

A. You can count on a Classic Products roof lasting 40 to 60 years and beyond. To put it in context, the average life span of a wood shake or asphalt roof is 12 to 20 years (in spite of weak warranties and claims to the contrary). That lifespan can be shorter depending on many factors. Made of oil impregnated paper, asphalt begins to deteriorate as soon as you expose it to normal weather. Shakes deteriorate rapidly as well in spite of frequent and costly cleanings and treatments. A metal roof, however, will never decompose nor require maintenance. All of the above roofing materials are well-outlasted by Classic Products roofing, which retains its good looks and durability decade after decade after decade.  more
