Once properly installed, a metal roof can last as long as 50 years or more, but it will depend on the material that you choose to make your metal from. A traditional shingle roof could be replaced over 3 times in the lifespan of a metal roof. Metal roofing seals out water, blocks high winds, and is a resilient roofing type which will allow for the snow to shed from the roof easily. Metal is resistant to fire, rot, mildew, and insects, increasing the life expectancy of the roof materials.
Metal roofs have been found to last between 40 and 70 years, but it depends on the material that you choose to make your metal from. This is much longer than traditional asphalt roofing that lasts only from 10 to 20 years. Metal roofs also can withstand strong winds and is a resilient roofing type.
Metal roofing materials reflect the solar heat (radiant heat) from penetrating into the attic and inside areas, reducing energy costs. The weight of a metal roof is less than that of shingles, which reduces transportation costs and handling costs. Metal roofing can be placed on top of some existing roofs which reduces the construction cost.
