Whether you're looking to buy a home or have owned your home for years, it's always beneficial to have knowledge of the life expectancy of your home. For those of you who have been out looking at Atlanta homes for sale, you and your real estate agent should be asking questions like, "When was the roof last replaced?" and "How old are the heating and air systems?" Perhaps you own your home and know you're on the verge of needing to replace your roof and would like to know wheich type of roof has the most longevity.

Well, your answers are here! For the complete list, you can check out the National Association of Home Builders "Study of Life Expectancy of Home Components" by clicking here and saving a copy of the PDF for yourself. Happy house-hunting or house-improving!
