umm, its the same roof. The way I tried Ripple Roof was to pull on those crimps/undercut holds and throw diagonally right for what I remember to be a sloping rail which led in to the lip proper. Admittedly if you've got a biggish span it would be fairly easy. Would it have been original done by going for the lip directly?? The lip traverse, start sitting off rail was a better prob me thinks.
could you suggest a grade for the ripple roof lip trav?
