Caulking Roof
Since I never caulk the roof before I have some questions! This is on a fiberglass roof, when I was at the factory I got some CSL Silicone caulk is that what I use, or do I want the self leveling kind...

Many people plastic chisel up as much of the old Dicor as they can, and then cover the area with Eternabond tape (Amazon carries it in several widths).
If you have a Winnie type fiberglass roof, which are known to loosen on the edges, wind gets under the thin fiberglass, and rips part of the roof off. So you might consider using 2" Eternabond tape in the J-channel along the edges to prevent that problem. Also, many people use 4" Ebond to seal the front and end cap to the roof.
Here's a link to my blog where I did just that as PM: Fiberglass roof Preventative Maintenance.
