I wonder how they get them to stay in place. It’s not a steep slope, but it’s definitely not a flat roof. So far I have resisted the urge to ring the doorbell and ask about the roof.
The gravel stabilizes the tar somewhat. But yes. And gravel washes off the roof too. And then the roof leaks the next time you get rain. They’re typically initially installed with hot asphalt and then patched with tar until the homeowner gives up and buys shingles. There’s a good reason you don’t see gravel roofs very much.
Phar out. I wonder what they use for waterproofing?

They must have used some type of resin/ epoxy.
They use tar.
You would think the tar would ooze downward on very hot days. (Yes, we get them here.)

The roof in the picture isn’t just gravel, it’s got fist size rocks in it as well. Gravel alone I could understand.
EPDM is the most common material for modern rubber/stone roofs in commercial applications.
