Isata 3 roof has dip at edges

[caswelld]

I was just up on the roof and noticed that on each side, near the edge there is a slight dip or trough that runs the length of the MH. It's a little less than 1/4" deep, but it is there. The picture doesn't show it well, but you can see it from a ladder.

I caused a leak in my sunroof when a leaf made a small dam & water came in over the caulk.

Is this normal?

Does it run all the way to the front where the AC drains off the roof? I know i get a steady stream coming off when the AC is running.

Yupe, both sides.

I think it’s just the condensate drain. How did it impact your sunroof which I assume is in the middle of the roof? How close to the AC drain is the sunroof?

The sun roof is right near the DS side edge and the a/c drain exits about 6" aft of the aft edge of the sun roof hatch.

We’ll, I found a small hole in the Dicor caulk at the aft edge of the sunroof. The a/c water was running down the roof and along the edge of the sunroof. I got a tube of Dicor at CW and fixed it today.

Thanks to Brian for the caulk diagram he made. That made it easy to know just what to get.

That dip is normal. We use a metal piece at the "curved edges of the roof" that goes from the sidewall, over the roof decking. So when the roof is laid over, it is common to have a little low spot there at the coping-to-decking transition.

I have the same thing on my Isata 5 in numerous places, and I have a crown right in the middle, a nasty looking bump. Luckily with all my issues, I at least cannot see these. What I don't understand is for an aluminum machined truss system you would think it would not have this, but they use some sort of plywood up there and if someone cracked a piece it could explain this. I also have the roof creaking because it's detached from the plywood near the solar panels, that sounds freaky, not sure if it matters structurally.
