The answer to 'lifespan of roof replacement' is that the average lifespan of a new roof is 20-30 years, depending on the roofing material used. Asphalt shingle roofs typically last 15-30 years, while metal, tile, and slate roofs can last 40-70 years with proper installation and maintenance.
The lifespan of a roof replacement depends on factors like the climate, roof pitch, ventilation, and how well the roof was installed. Proper maintenance like regular inspections, clearing debris, and fixing minor issues can also extend the life of a new roof. Calling in a professional roofing contractor for periodic checkups is recommended to ensure your roof is in good condition and maximize its lifespan.
