Metal shingle facts

Knowing the good and bad about metal shingles will help you select the most suitable roofing material

There is no such thing as the perfect product, but there are ways to find the most suitable material for each roofing application. For every roofing job, you review the specifications, understand your customer's wish list, examine the building and consider which roof system will meet your customer's needs. When considering metal shingles, knowing their good and bad attributes will help you determine whether they are the best fit for your project.

The good

Long service life

When buying any product, you want it to last. Metal has been proven to last longer than many other materials. According to a Troy, Mich.-based Ducker Worldwide study in 2007, a nonmetal roof lasts 15 to 23 years—composite shingles, 15 years; single-ply membranes, 20 1/2 years; polymer-modified bitumen, 23 years; and built-up roofing, 23 years—compared with metal roofing, 41.6 years. For a building owner, this difference in life span means cash savings.
