Investigate further.
I have had drip rails rust out and all that was needed was new rails. On the other hand I had a small hole same spot. When I pulled the windshield there was rust inside behind the rubber. After I peeled it back a bit with a flap wheel it opened up. Gasket looked good but must have failed at some point. Replaced entire roof and down to solid metal on pillar. All good. Learning experience for sure. Thing to do now is take a look see and determine where the rust stops and good metal starts.
