I used sealant when I installed my roof rails for a couple reasons.
1) I got them secondhand from a forum user and the hardware and washers were used; figured they were supposed to be single-use items, so why not add some extra protection if reusing them, and...
2) OEM Tacoma roof racks were notorious for leaking if you just used the factory washers. I used sealant when I added them to my old Tacoma and never had a problem.
