2018 1500 Rear Door Roof Leak

[frankthedog13]

Bought the truck (18) months ago and had water stains on the roof (can see old marks in photos). Didn't think much of it, was told it was taken care of and i had no issues. Fast forward to this past weekend, you can see the leak is back. Right above the drivers side rear door. I'll be honest, not a big car guy, any input/direction on a resolution is appreciated.

a common problem is the third brake light (on rear of roof) develops a leaky seal. There are a number of posts on this on this site and solutions. Not sure if this is your issue fwiw.

This looks like your roof antenna is leaking. If you plan on doing the work yourself, I can walk you through the steps. It will probably take about an hour for a first timer to fix, but it can be done in under 30 minutes...
