This is actually on the Fairview High School building, buts it under CU 'cause that's the closest area. Walk around from the main entrance of the school to the South and find the Souther most point of the library. The corner here is climbable. A ledge runs horizontally at about 9' and 16'. The trick is to connect the ledges. Footholds non-existent. Vertical slats comprise the holds, but fishing around proves some are better than others. Tops out onto roof (only known way to get up) around 17 or 18' (but easy once feet get onto first ledge).
