Caulking

[scampbell624]

I recently purchased a used pop-up and it is in need of new caulking on the roof. I believe it was Dicor that was recommended on some of the other discussion posts. My question is, do I need to remove all the old caulking before I put down the new stuff or can I just caulk over it? Also, the corners are starting to pull away when I latch the roof. Probably from the previous owner having them too tight. Should I install screws to hold it down or will the caulk help with that? Thanks for any advice.

Clean the old caulk and remove any obviously loose caulk,  then recaulk. Caulk will not help with the corners
