Most roofs last 25-30 years or so. I suspect the amount of time that solar panels need to be replaced is around the same time since replacing the panels after you replace the roof only a few years beforehand might be most costly.
Asphalt shingles in rainy locations. Unless you want to shell out for slate, concrete, or metal roofing, expect to replace the roof every 15-20 years.
Slate is the way to go if your structure can support the weight. You’ll get 100+ years out of it, but it’s up to 10x more expensive than asphalt shingles and many owners want the cheapest option due to finances or not intending to live in the home long term.

Oh, okay. Around here, those are only used for garden sheds, maybe.
