My very non-scientific impressions: I think cross-sectional profile,
shape(rounded vs hard-chine), width, and depth of the boat contribute a lot
to ease or difficulty orf rolling. Logs are easy to roll. Wide flat planks,
especially big ones, roll
with difficulty. Low-volume boats roll a bit more easily. For those of us
who enjoy doing layback rolls, shallow depth helps.

Like Bill, I've been away for a while, so I'm very late to this thread. 
There is no doubt to me that some kayaks are easier to roll than others. 
One thing I've noticed that seems to make difference that no one else has 
mentioned is flare. It seems to me that kayaks with a lot of flare in the 
midsection, such as Sea Lions, tend to flip quickly once the gunwale dips 
below the surface; these kayaks are harder to hold on edge, and take more 
effort to get the gunwale above water. An easy-rolling kayak like the 
Romany, in contrast, has nearly slab sides and is also easy to hold on its 
side by sculling.
