The average lifespan of a roof is around 20 years. However, this number can vary greatly depending on the type of roofing material used, how well it’s maintained, and the climate conditions in your area.

Typically the lifespan of a roof depends on the material. For instance, asphalt roofs last around 20 years while metal roofs can last up to 50 years.

It’s important to keep in mind that a roof’s lifespan can be shortened by several factors such as improper installation, exposure to the elements, and foot traffic. So if you’re looking to install a new roof, be sure to consult with a professional who can help you choose the right material and ensure a quality installation.
