Full Answer

Metal roofs last up to four times longer than asphalt roofs. Because they can withstand impacts, hold up to high winds and do not crack or corrode, metal roofs offer a longer lifespan with less maintenance. While asphalt shingles remain functional for up to 20 years, the expected lifespan of metal roofing is 70 years.

Some consumers install metal roofs to reduce their cooling costs. Since the material reflects the sun's heat, the home maintains a more moderate temperature. Air conditioning expenses can drop between 10 and 25 percent. Other consumers like the fact that the roofs are made from up to 95-percent recycled material. Furthermore, the entire installation can be recycled at the end of the roof's life.

On the negative side, metal roofing costs two to three times more than asphalt roofing for the same square footage. Homeowners who add insulation to reduce the sound of rain or hail falling on metal cause the price to increase even more. Other concerns include repair costs, water damage and rust in certain climates.

Metal roofs can be made from tin, copper, aluminum, zinc or galvanized steel.
