Roof needs mowing

What do you call this?! Whats the method to control water seepage from the roof / LAWN to the house below?
Took this photo in Cheney Washington though not a house I inspected. Would like to see the inside.

Sorry, did’t realize the photos I uploaded were rejected for being too large.
Here they are.

I would have to call B.S. on the earth quake proof in ground house as they claim. Scientist in Japan thought the same thing untill 70% came down after a hard earth quake.

It’s an earthship. This is the kind of stuff I was referring to in my topic on “Green Homes”.
