In the middle of the Red Slab is a roof system that provides entertainment for three or four routes. Trundelero takes the leftmost line through the roof. A steep slab runs past two bolts to a lower-angle section to the roof. The roof is steep, but juggy, and feeds onto another long steep slab to the anchors. The crux lies somewhere above the roof, but the climbing is generally continuous on the upper section and keeps you thinking all the way to the chains. Don't be surprised if you occasionally find your feet above the pro - stay calm because another clip will be coming up soon. The name is derived from the fine sport of Trundling, of which there was much early on, but nowadays it's pretty clean.
For the roof move, I got bunched up beneath it, then reached a right hand high into the crack and jammed directly above a crystal-like piece. After that, it's pretty juggy. A great climb, not a one-move wonder.

While there are indeed jugs above the super fun roof, be careful as a fall before the next clip after the roof might land you on the slab below...I placed a yellow C3 cam in a thin crack (I think similar size to a green or yellow Alien) right at the top of the roof and that made the moves above a bit more secure and less intimidating. The bolt at the roof is quite low once you move up...There are also a few other cam placements on the rest of the route; however, most seem to be in the easy sections and not the crux section. To undercling traverse out and up to the chains is fun.
