Very few rambling roses repeat flower but Malvern Hills form David Asutin is one. However as Pansy says, roses lose their leaves in all but the mildest winters so you need to combine it with another evergreen climber.
Clematis armandii would be good as long as you don't have heavy frosts in spring when it is in flower There are two honeysuckles which are evergreen. One flowers in spring and the other in summer.
Lonicera japonica 'Halliana' AGM: An evergreen or semi-evergreen, vigorous climber with dark green leaves and white fragrant flowers from spring to summer. Height: 10m (33ft).
L. henryi: This is an evergreen, vigorous honeysuckle with purplish-red flowers between early and mid-summer, followed by purple-black berries. Height: 10m (33ft).
You will need to install tensioned training wires at 12 to 18 inch intervals up your fence in order to be able to train the stems as horizontally as possible to get maximum coverage and flowers. Roses and clematis are both hungry, thirsty plants so be sure to add plenty of well rotted manure and garden compost to the soil before planting and give them a good watering and mulch after planting.
