which climbing/rambling rose?

[Psi (Pronounced 'Si'!)]

Great topic.

I'M in the process of having the pebble dash removed from the front of my house, re-pointed and new windows put in.  It is a terraced house in North London with a south facing front garden - it gets seriously hot in summer.  So, I'm thinking of a rose that can reach 15-20 feet, is pink or white, not too vigorous with lovely 'old rose' flowers which repeat for as long as possible.....any ideas?  oh and do these guys need a lot of support....I love roses but am a novice.

thanks so much

Simon
