Generally speaking, we can expect properly installed and maintained asphalt shingle or tile roofs to last between 25-35 years. If you have purchased a home and do not know when the roof was first constructed, we recommend that you have a roof inspection to determine the remaining useful life of your roof. This will help you to both better maintain the roof to maximize longevity, as well as begin to budget for a new roof if you anticipate needing one while you own the home.
