Accend the two Lower Roofs pulling hard with plenty of gear. Belay on a large ledge. Go left and ascend the large upper roof using one rusted peg for protection (not as bad as it sounds). Gain the juggy hand holds above the roof placing a larger cam (4) and ascend the top section with loads of gear and amazing positions. This exposure on the top I believe gives it the E2 grade. The top section is well worth the effort!
