In 30 years how many times will you have to redo your roof I think one of Tesla solar roofs points was that many houses in the US have to reshingle. Although I still don't think it might be worth it for you.

It will almost certainly require replacing and/or serious repair long before the "lifetime of the house" is up.
I live in a neighborhood full of slate tile roofs and tile replacement is a fairly routine occurrence. Are you positive that no tiles have been replaced in the past 100+ years?
