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.
What roof only lasts 30 years? I've seen even unglazed concrete tiles, the really cheap ones that were from the 60s and still fine.
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.
a biosolar roof would be a nice
I'm married. Please stop trying to seduce me.
apparently insurance companies will replace the whole array if one panel gets hail damage. this means there's plenty of perfectly good panels for free out there. perfect for powering or heating a tool shed or something
