Under normal circumstances, 3-tab asphalt shingle roofs should last 15 to 20 years before needing to be replaced. However, architectural asphalt tile roofs are a little more resistant to the elements due to their design, and can last up to 10 years longer than 3-tab asphalt shingle roofs. Depending on the type of roofing material, where you live and how well you maintain it, your roof could last anywhere from 15 to 100 years. When it comes to roof replacement, the age of the roof plays a big role.
The 20-year mark is a good standard to follow if your area doesn't experience regular adverse weather conditions. In some cases, a qualified roof repair company can replace specific shingles, but the problem may indicate a larger issue. Asphalt shingles and composite roofs are the most common materials and also tend to last the shortest time (typically about 20 years on average) before they need to be replaced. Waiting for something to actually break, crack, or leak can be harmful to your home and may require roof replacement much sooner than expected.
Depending on the magnitude of this damage, it may take between one year and five years to fully replace the roof. Common metal roofing materials, such as steel and aluminum, should last 50 years before needing to be replaced. If you're looking for a forever material that doesn't need to be replaced during its lifespan, a slate roof is a great option. When it's time to replace your roof, it's crucial that you find a quality roofing contractor that you trust to install.
As long as everything is done correctly during installation, you should start budgeting for roof replacement around age 22. It's best to be proactive and look for early signs that a roof will need to be replaced in order to minimize repair costs and the risks of injury or property damage.
