2003 Honda Civic how to remove drip rail

I have a 2003 Civic and (long story short) there's a crack under one of the drip rails on the roof. I'm trying to find out how to take that rubber piece out without damaging it. I've lifted the end and it appears to be held down by a metal tab.
(I'm calling it a drip rail because that's what I was told that it's called. But I'm not talking about the part that's right above the door, I'm talking about the strip that runs from the corner of the windshield to the top of the back glass.)
Can you tell me how to get that out and back in without damaging it?
Thanks a lot.
