There are lots of clematis that would be happy here if you can provide wires stretched between vine eyes screwed to the wall in horizontal rows anything form 12 to 18 inches apart. You could plant more than one to have a variety of colours of flower but do make sure they are from the same pruning group or things could get complicated. Viticellas are probably the easiest group as they are vigorous and can be pruned almost to the ground every March and will then produce new growth with flowers all summer long and into autumn. Have a look at Betty Corning (scented), Etoile Rose, Pagoda, Hagelby Pink and its white form, Lisboa, Melody. Nelly Moser and Perle d'Azur have larger, flatter blloms and can be treated as group 3s and pruned like th eviticellas if you want to contrast form as well as colour.
Climbing roses such as Golden Showers, Paul's Scarlet and New Dawn will also do well and provide repeated flowering through the summer.
Both roses and clematis are gross feeders so need really good soil preparatin and annual feeds to keep them looking good and blooming.
