I have two climbing roses which aren't doing very well and to be honest I'm a bit bored of them. I intend to replace them both with clematis armandii so can I grow the clematis in the same soil? Will something like rose sickness affect the clematis?
TIA.

I've grown clematis where roses have been and haven't had a problem, but can't give you a definitive answer I'm afraid.
Provided the roses aren't disease-ridden in any way, I think the main problem would be that the soil is lacking in nutrients.
Thanks both. The roses are virtually leafless due to black spot. This is despite spraying and attempting to tackle the spores. I just seem to live in a really bad area (none of my neighbours have roses. Bit of a clue there that I ignored!) and even 'Compassion' isn't doing well. I'm hoping that the clematis will fare better as I have Nelly Moser in the same garden and it seems to be thriving.
You should be fine. If you have fungal problems, it's often a sign of clean air, believe it or not - city pollutants kill some fungi. A major example of this is rust on hollyhocks.
Clematis armadii gets huge and doesn't particularly like pruning!!
