How long can a roof last?
Service life depends on material, installation, ventilation and weather — not a single slogan.
There is no honest one-number lifespan
Slope, ventilation, flashing quality, storm history and maintenance change remaining life. Two houses on the same street can need different next steps.
Age is a factor, not a verdict
A ten-year-old roof with wind damage may need work. A well-detailed older roof may still be monitored. Inspection is how that is discussed.
