Roof Rack question

[Bounty__Hunter]

Will the crossbars of an OEM roofrack on a WK withstand quite a bit of upward force? Looking to haul one of my canoes strapped down to only the crossbars and want to be confident its going to stay attached.

I don't know how different the roof racks from a durango to a jeep are, but i had a king size double pillow top mattress tied to the top of my durango going down the highway at 55-60 and it was still there when i got it home.
