How can a solid slate roof need replacement after only few decades?
Putting in a new solid slate roof today is stupidly expensive, and basically nobody does that outside of the very top end. You can probably change your asphalt shingle roof 4 times for the price of putting up a slate roof.
Essentially it's a question of priority. Most people probably don't plan to live more than 20-25 years in their current house, so why not go for the cheapest option that gets the job done and let the next owner worry about fixing the roof.
- hef19898 6y agoThat's maybe the reason, European houses, even if the initial owner doesn't plan to live there for ever, are buit to last basically for ever. but wouldn't make something like tesla's solar roof make more sense for houses like that, those that already use solid shingles? If I don't care about my house for more than 25 years anyway, I think I'm not the ideal solar roof customer anyway.

You can probably change your asphalt shingle roof 4 times for the price of putting up a slate roof. I'm assuming you're talking about US? In UK all new houses still have solid slate roofs. Even the cheapest new houses(around £100k where I live) have a solid slate roof that is expected to last 50-100 years.
