The expected life of a given roof in a given environment has the most impact on the roof’s overall life cycle cost. Why? If a roof doesn’t last the desired 20 years, the owner is likely to incur higher than average maintenance costs and, towards the end of the roof’s life, also major renovation costs; maybe even a total roof replacement.
