A typical residential roof's lifespan varies significantly based on the material used. Natural slate leads the pack with 80-100+ years of durability, followed by clay tiles at 50-100 years. Metal roofing systems last 40-70 years, while concrete tiles provide 40-75 years of protection. Cedar shingles typically last 25-30 years, and the most common material, asphalt shingles, serves 15-30 years depending on quality and environmental conditions. Built-up roofing systems last 20-30 years, and basic felt roofing typically needs replacement after 10-20 years. These lifespans assume proper installation and regular maintenance, with local weather conditions playing a crucial role in actual longevity.
