The lifespan of a roof depends on several factors, such as the type of roofing material, the climate, and the level of maintenance it receives. On average, a roof can last anywhere from 15 to 30 years before it needs to be replaced.
Asphalt shingles, the most common type of roofing material, typically last about 20 to 25 years. Metal roofs can last up to 50 years, while clay or concrete tiles can last up to 100 years. However, these estimates can vary depending on the specific roof and the conditions it is exposed to.
It is important to regularly inspect and maintain your roof to ensure it lasts as long as possible. This can include cleaning the gutters, removing debris from the roof, and repairing any damage as soon as it is noticed. A professional roofing contractor can provide more specific recommendations for your roof.
