The answer to 'lifespan of roof installation' is that a properly installed roof can last 20-50 years, depending on the roofing material used. Asphalt shingles typically have a lifespan of 15-30 years, while metal, tile, and slate roofs can last 40-100 years with proper maintenance. The actual lifespan of a roof depends on factors like climate, roof pitch, ventilation, and the quality of the original installation.
Regular roof inspections and timely repairs are essential for maximizing the lifespan of any roofing system. Homeowners should have their roof inspected by a professional roofing contractor every 1-3 years to identify and address any issues before they become major problems.
