Sit start on a hidden undercling feature in the very back of the roof in front of a slab of rock lying in the landing, as for "Rock Candy." Climb into the roof. After the first couple of moves in the roof, trend right into more crimps finishing on "Pop Rocks Stand," topping out on the shelf.
Almost did it in a session so hard to grade. I can reach all the moves and I love roofs. But then there are other problems of equal or lesser grades that feel nails. Idk. Fun either way.
