Aside from propaganda, what if the roof only lasts 25 years?

And doesn’t mounting panels on top of a roof increase possibilities for leaks?

I really would like solar to work. But have seen too many crazy storms and even a minor tornado in the past 5 years to make me wonder about 20+ year longevity.

I would personally never mount panels on the roof in a context like this one, a house in the middle of nowhere. They should just be on a pole, mast, or frame. Anywhere but the roof.

Furthermore, maybe, at low latitudes you can just lay them on the ground and at high latitudes just mount them vertically and the snow will drop off. Skip complexity.
