Solar 101: Is my roof ready for solar? – pv magazine USA
WEBApr 15, 2021 · A typical roof has a 25-year life expectancy, so roofs in the range of 8 to 20 years present a dilemma of wasting many costly “roof years.”. For instance, a 250,000-square-foot white thermoplastic (TPO) roof on a commercial structure might cost $5/sq. ft.—on the order of $1.25 million–to replace. That amounts to roughly $50,000 per roof ...
