Most of the roofs you mention are not built to support load.

  As someone from the Alps, I'd really see a source on that. Most alpine roofs are built to survive extreme snow loads. My father just covered his roof in solar and that roof was built in the 70s.

  Thats why they are dismantled every year just before winder and rebuild after last snow melts.
