Non-metal roofs start to deteriorate as soon as they are installed and exposed to the elements.
UV rays, high wind, and severe temperature changes can damage most other roofs, sometimes
drastically decreasing their service life. The average life span of a NON-metal roof varies
between 15 and 20 years. Metal roofs can last 2 to 3 times that long, depending on style,
quality, and workmanship. In many cases, a metal roof can be the last roof you’ll ever install
on your home.
