Does steel siding or aluminum siding last longer? Does steel siding or aluminum siding last longer?

Steel siding is a popular choice among homeowners because of its durability and energy efficient qualities. A homeowner that installs steel siding won't need to worry about termites, rusting or rotting. Steel siding lasts for 40 years. The downside is that in most cases, the steel siding needs professional installation and is harder to manage than aluminum siding.

Aluminum siding is less durable than steel siding, lasting about 20 years. However, aluminum siding is easily maintained and comes in a variety of colors and has vinyl covering that protects the aluminum siding from dents and scratches. Aluminum siding requires regular cleaning and painting.
