Direct answer
The practical answer first.
There is no single guaranteed lifespan. Material type, installation quality, ventilation, attic heat, storm exposure, tree debris, maintenance and previous repairs all matter. Age is only one factor; the roof’s actual condition and performance should drive repair or replacement decisions.
