I'm not rly convinced that roofs are the best places for solar.
1. Then you need small scale transformers 2. Lots of roofs have shadows on them a lot of the time, like from trees or other nearby buildings 3. Most roofs have to get replaced every 15 years 4. Roof installed solar is fixed in place
I think parking lots, rural empty land and the like are a better starting point that avoids all 4 of these issues.
I have solar on my roof btw.
Rooftops, residential or commercial, have the benefit of being "free" land for installation. It isn't used for anything else, typically.

What in the world?? What are your roofs made out of?
Asphalt shingles. As usual the US is building cheap and light and these things don't last.
Rooftop solar has the benefit that you distribute the investment cost over a large number of people, even if the costs are a lot higher than grid-scale installations on the ground.
I'm surprised to hear that you need to replace roofs every fifteen years. What are they made of? The roofs I know last decades longer than that.
