Good Screen Shrub for a Rockery?

Good Screen Shrub for a Rockery?

I am about to take a Portugal Laurel out of the rockery between my neighbour's back yard and mine. He is worried the roots are going to destroy the rockery, and I agree with him. So I need to find a nice screening tree/shrub, 6-10ft tall and about 4-6ft wide. The spot gets about 6 hours of sun a day. I need something that doesn't have large roots that will damage the rockery. An evergreen would be nice. I was looking at snowball viburnum or witch hazel, but am still unsure. Any advice or suggestions would be most appreciated!
