It's been three months since I last cleaned and thoroughly inspected my roof. I was surprised to see that GDRV had completely resealed the front cap when I got up on the roof (thanks much). I started with washing the roof with a bucket of water and Dawn dishsoap.
Then, I did a thorough inspection. I found a few small pin holes and cracks in the sealant that I touched up with SuperFlex self leveling sealant in beige. However, the back seal on the cap was starting to show some pretty significant cracking, and I also found that the sealant was not adhering well to the roof membrane. If I hadn't have pulled up on the sealant to see that it wasn't adhering, rain water could have migrated between the sealant and roof membrane and caused a leak. So I ran a new bead of sealant along the entire length of the back cap. It took two tubes of Superflex to seal everything up.
In regards to the SuperFlex. I purchased it at Camping World. Alpha Systems manufactures both the roof membrane, and the SuperFlex sealant. So of course, it's the brand they recommend. I found it interesting that the tubes of sealant state that they have a "One Year Shelf Life". But neither I nor the Camping World employees could find a manufacturing date anywhere on the tubes.
