Is there an easy way to lower one corner of the headliner in a '14 Ram?

Hi All.

I have a '14 Ram 1500 Crew Cab. I clipped the sharktail satellite antenna on my garage door and it loosened a bit (did this before and it entirely ripped off). I am hoping there is a way to just lower the drivers side rear portion of the headliner so I can see if I can simply tighten the sharktail back to the roof. There is a slight gap and am concerned of water damage when it rains.

Thank you,

You have to take off the two clothes clips in the rear, and drivers rear pillar trim. After that if you have tiny hands can get up there to tighten it. I installed the oem remote start system and this is how they said to lower the headliner to install the remote start module.
