Should you get a metal roof?

Imagine not having to worry about your roof for the rest of your life.

Your wish could come true if you invest in a metal roof, which has an average lifespan of 40 to 70 years — decades longer than conventional asphalt shingles, which last 20 to 30 years at most.

Demand for metal roofing is growing, and not just because of the longevity. They can sustain hurricane-force winds, won't spark and ignite (a key feature in wildfire zones), they save energy and can reduce utility bills, and are completely recyclable. They can also enhance your home's resistance to pests, mold and rot, and dramatically increase your home value and curb appeal.

There are downsides, however. The longer lifespan of a metal roof comes with a larger price tag — as much as two to three times the cost of other roofing materials. But for homeowners who intend to stay in their homes for a long time, the investment may pay off with lower energy costs (25 percent less for cooling), easier maintenance and reduced homeowners insurance premiums.

Metal roofs can be louder than traditional shingles, but not much. Stone-coated metal roofing is said to be the most quiet. Depending on how the roof is installed, the loudness of a metal roof ranges from 52 decibels to 61. Asphalt shingles are rated about 46 decibels.

If hail is a concern, stone-coated metal is the best, rated for hail up to 2.5 inches.
