Bad roof ????

At first I was nervous but not so much after watching the videos and reading through the forum.  No signs of leakage and seals look great.  All appears very solid around penetrations.

Should I be worried or this a pretty common condition?  

Toyanvil, do you mean check to the bolts to see if they are loose?

Sorry, the solar array we used vhb tape on was on racks. We used clamps similar to these. very common in the solar industry.

I wasn't meaning to suggest that you use them directly to the roof of your rpod, although you could if you could find the roof structure to attach them to. For fastening to the roof surface many folks use the technique in the Renogy manual. 

In your case if your roof fiberglass is very loose then it might be that nothing attaching to the roof surface will work. You might want to consider running a couple of pieces of rail across the roof side to side and then attach the solar module(s) to that with the top down clamps. The rails can then be solidly mounted to the wall structure at the top corners. The top down clamps slide in the rails so that you could place them wherever you want The other benefits of  this approach are that there are no holes in the roof itself and the solar modules get cooling air under them. 

Use a mechanical fastening system, its more certain and secure.
