The huge, untapped potential of planting rooftop gardens in cities

It is untapped for countless good reasons. Solar panels on the other hand are along the lines of the trouble of a tiled roof. Makes things more expensive but doesn’t actively try to rip a hole through the water barrier.
I don't get green roofs. How do you make it so you won't have water infiltration and leakage?
Same as with the rain. Have a waterproof barrier between the plants and the house. Sod, thatch, terracotta, asphalt, plastic, even concrete if you don't plant rock-breaking plants.
I like the idea, but the years of dealing with leaking water have made me very skeptical...
I needed a new roof a couple years ago. Only 1 roofer in my whole city offered vegetated roofs. He only had experience with commercial installations, not residential.
So indeed there is a shortage. No idea why roofing companies are not on the ball with this.
I have a rooftop garden. Keeps my room cool, and I get all the herbs and veggies I want. But then, my house is brick, mortar, and RCC, so water isn't a problem. I have not yet seen it have any effect in terms of seepage, tbh. The only thing someone might be worried about is weight, but then, soil is only half again as heavy as water, and you don't need more than a foot for growing good crops.
How deep is the soil on roofs typically?
