The average lifespan of a roof typically ranges from 25 to 50 years, but the life expectancy of a roof depends on the quality, durability and type of material chosen. Generally, roofs can last anywhere from 20 to 100 years, depending on the materials used, the quality of the workmanship, and the climate. More durable materials tend to cost more. When selecting a new roof, it is important to choose a roofing material that suits the climate of your region and the slope of the roof.
It is always best to have a professional roofing team install a roof, but for those who are capable and dedicated hobbyists, asphalt roofs are the easiest to install. Under normal circumstances, 3-tab asphalt tile roofs should last 15-20 years before needing replacement. Architectural asphalt tile roofs are more resistant to the elements due to their design and can last up to 10 years longer than 3-tab asphalt tile roofs. Asphalt shingles are the most common roofing material in the US and are expected to last between 15 and 25 years.
An asphalt tile roof can last between 15 and 25 years if properly maintained and barring any significant weather event or disaster. When installed by a quality roofing company, many types of roofs can last for 50 years or more, unless there is a severe storm or a large fallen tree. Clay roofs are especially popular in hot, sunny climates and can easily protect your home for 50 years or more before needing replacement. If you're comfortable with DIY projects, there are a variety of guides online for performing roof repairs.
As long as your roof has been properly ventilated and installed, you should get close to 25 years of roof life. If your property is located in an area where hurricanes are likely to occur, then you should invest in a fully adhered membrane roof system rather than a mechanically bonded single-layer membrane roof as it is more likely to withstand the winds and water of a hurricane. Common metal roofing materials such as steel and aluminum should last 50 years before needing to be replaced. However, if your roof has many layers that have built up over the years, you may want to consider replacing it completely.
If you know you're going to sell your house in 2 to 5 years, you'll probably need to replace the roof in order to put your house on the market.
