Structural failures experts may opine on the National Association of Home Builders & Bank of America Home Equity Study of Life Expectancy of Home Components:
How many years of service can a home owner reasonably expect from the various components of a home? An NAHB study sponsored by Bank of America Home Equity takes some of the mystery out of the subject.
The life expectancies of the components of a home depend on the quality of installation, the level of maintenance, weather and climate conditions, and the intensity of use. Some components may remain functional but become obsolete due to changing styles and preferences or improvements in newer products while others may have a short life expectancy due to intensive use. The average life expectancy for some components has increased during the past 35 years because of new products and the introduction of new technologies, while the average life of others has declined. NAHB’s last such study on the life expectancy of housing components was published in Housing Economics in August 1993.
