The point about heating behavior might still be a topic, are clay tiles also the better choice here? Is black perhaps disadvantageous here, because that is pretty much the only thing I had directly decided. Does it make a difference if I plan to cover as much as possible with photovoltaics?
The question somehow slipped by, so as motivation to cover as much photovoltaics as possible: Rooftop photovoltaics are the best and cheapest heat protection you can get. Make the roof as smooth, straight-lined, and unshaded as possible and put photovoltaics on as much as possible. For a flat roof, also on the northern roof surfaces. And if everything is covered with photovoltaics anyway, the roof tile/shingle doesn’t matter:
Although I’m not really a fan of black – in combination with all-black photovoltaic modules, black roof tiles do make sense.
