Climb Sickle (5.10a) but instead of continuing to traverse under the roof, go straight out over the roof. a V5 boulder problem is the crux of this roof. If the roof proofs to be to challenging, you can still bust out right under the roof to finish on Sickles ending moves.
Make sure the second is tall enough to reach the gear in the roof!! you will have to leave it if they cant.
Left of Sunshine Slab, follow slab up to corner of Sickle, follow corner up and out the middle of the roof.
