The answer to 'lifespan of roof' is that the typical lifespan of a roof is 20-30 years, depending on the type of roofing material used. Asphalt shingles generally last 15-30 years, while metal roofs can last 40-70 years with proper maintenance. Tile and slate roofs can last 50-100 years or more with good care.
The lifespan of a roof depends on factors like the quality of the materials, installation, ventilation, and how well the roof is maintained over time. Regular inspections and prompt repairs can help maximize the life of a roof. Homeowners should also be aware of signs of wear and tear, such as missing or cracked shingles, to address issues before they become major problems.
