well, roofs are my specialty and I don't know how to grade them, so take my advice with a grain of salt. however, these haven't been mentioned:
3rd pitch variation to yum yum yab yum (5.6)
bunny's roof variation (5.6)
disneyland roof variation (5.??? or go around)
sundance (not really a roof, but overhangs for a few moves in a row, and worth doing for practice for something like high e)
then walk over on the ledge and set up a toprope on ghostdance (5.7R roof)
frogshead variation roof finish (5.6)
1st pitch of modern times (5.6 or 5.7 debatable)
all the above are good. in the "to do when feeling confident" category:
tequila mockingbird/dry martini (5.6 or 5.7+ ish) you can swing leads and just do the 5.6 roof on the short p1 and then set up a gear anchor if you want, if you want to avoid the 5.7 crux
