Roof Re-Seal of Cracked Dicor

[jamesp]

I have been on the roof of my 2008 trailer and I have to think that the sealant looks pretty good. I found some small places on the end seals and a suspect spot on the antenna cord boot. I have small cracks in the Dicor but they only appear to be surface cracks and very shallow. It will only take a small smear to fill these cracks and do they really need to be filled? I want to eternabond the areas come spring and I don't want to put a large bead of Dicor on the cracks that I will have to try and cover up. I am attempting to post a couple of pictures that show the small cracks.

What are you asking?
Advice or just venting?

the cracks are probably not an issue but I bet the cord for the XM antenna is or is going to be - better seal at the least that part before it becomes an issue.

I'd hit where the XM cord is going into the sealant as mentioned by Sherdep- and the top part of the sealant in the first picture, otherwise your right, appears to be surface cracking...not bad!

Sherdep - I was looking for advice if I need to re-seal all of it or is it okay? No venting, it happens to all campers. I don't see how I can seal the small cracks without applying a big bead of Dicor or put it in the cracks with my fingers. The Dicor is thick and the cracks are shallow. I can imagine they will continue to crack deeper and have to be refilled. As stated in my original post, I plan to cover with eternabond in the spring.

wasnt sure - hence why I asked - advice is always good

If it was me I wouldnt worry about the cracks but I would worry about where the antenna cord for the XM goes in to the roof before it leaks and not make it to your re-seal.

If you are going to re-do it with Eternabond - (I have never used it so cant give advice on that) I would caulk the antenna wire if nothing else.
