Life Expectancy of Building materials.
The life expectancy of any building material is an average and depends on many outside factors, such as home conditions, routine maintenance performed/not performed, area of the country, and many other factors. The attached chart available by clicking on the button below are averages. We have seen appliances/HVAC equipment that do not last as long as the average and we have seen others that far out-live the average. Use this guide for reference only.
