I have a Hobie Outback, which is probably about the heaviest kayak you would want to muscle up solo on a roof rack. I ended up buying the 4x8ft folding trailer from Harbor Freight to make my life easier, and it works really well. Often I will just loosen the straps and leave the kayak on the trailer in my garage so that I'm ready to roll. I would really recommend a trailer... especially for around the town trips.
If you are set on roof topping, Rhino Rack has some assist bars and a "T loader" that goes in the hitch which really helps load kayaks and canoes. There are also more expensive systems from Thule and Yakima for loading some of the more common non-fishing kayaks, and those can be modified to work with fishing kayaks like the Outback (plenty of FB groups with that information).
Hope my data point is a help.
