I have a friend who had a green roof in Turkey. Green in the winter, and dry straw in summer, but it still protected the house from the sun's heat.
Yes, the roof offers wonderful insulation!
One aspect of the roof that we think about in summer is fire risk. The past couple of years here in western Canada have had crazy forest fires, and while they don’t usually reach us here on the coast, it’s possible. A floating spark could set our house on fire when the roof is basically tinder. So this year we are installing sprinklers for peace of mind.
Marta, I think it would be good to broadcast some seed over your roof to get some roots established and hold the soil on, as long as you’re still expecting some rain or can irrigate. I’m really impressed at the ability of succulents to propagate (and we have one native variety that seems to be self seeding everywhere) but still, coverage is slow. Getting some clover or grass started will help hold the earth in place, and you can still plant into it, especially after it all dies in summer.
Wildflower mix is nice too! My partner threw down some wildflower seeds at some point, and some of them come back every spring.
