I think it's a common problem, we get cuttings of roses from many
places, they root and then take off and we have no idea of their name.
I have 3 of such ilk, 2 are pictured below.
This double was growing in the garden next door to me in Barry when I
moved there, my neighbours moved in the same time and the rose had
been there for many years.
It covered about 4 ft of their hedge but grew my way and was around 20
ft long.http://i240.photobucket.com/albums/ff82/taffy4u2/2011/

The flowers are small and pinkish on the buds and reverse of the outer
petals.
The 2nd is a small flowered single that has reached almost 40ft in
places, I found it covering an old electricity substation outside
Cardiff about 20 years ago,
