Need Roof Crossbars

[BlueBird2021]

I have a 2021 Crosstrek and need to purchase/install system for carrying a kayak on my roof. My car has roof rails but not crossbars. Can anyone point me in the right direction to buy crossbars that I can install myself? I have looked on multiple websites, including Amazon, but am having a har time finding anything that says it is good for carrying kayaks.
