They look great. It's not a problem for them to get rain, btw. Roses seem to prefer it to tap water. It there's good drainage rain isn't a problem. When I repot, I try to keep the rootball with its soil intact by putting soil in the bottom of the new pot and filling in around the old potted rose while it sits in the new, if that makes sense. Then I hold my hand over the soil of the old potted rose, invert it after slightly squeezing the pot to loosen it. Then it's easy to plonk in the new pot without root disturbance. In your climate, this may not be a problem. Keep us posted!
