Sealing up leaking storage tank vents
Hey, people. I was putting in a new vent cover and realized just how bad my storage tank vents looked. The rain caps had disintegrated off and a previous owner just bought new vents, dropped them on...

That is a much better way to communicate Mocoondo and I appreciate your clarification. I understand what you are getting at. I think the repair you show above is a better "permanent" fix for someone who does not intend to rebuild the roof at a later time.
My style of communication is usually to ask why they did XYZ and hear their reasoning before going fully into why I don't think that might be the best way.
In that spirit I will add more detail. I was concerned at the dark ring where the old plastic cover was contacting the roof. It looks like someone used an epoxy (like liquid nails) to adhere the vent covers last time. It adhered really well in some spots and was a bear to scrape off, but it did not bond on some spots. I believe that is how moisture got in and caused that ring of mold between the layers. That means there was also moisture getting to the wood.
The poor job on the previous repair and the rotted wood are why I chose to use Eternabond. Eternabond is extremely good at flat repairs on aluminum, you can clearly see if it loses the seal and is less of a problem to clean off. It is also quite flexible and self healing. I believe this repair should completely seal up the aluminum roof sheet and prevent moisture from getting in at all through those giant holes in the center, until such time as I can tear off the entire rack up there and properly repair the rear of the roof next Spring/Summer. This repair is incomplete and I plan to finish sealing the outer diameter of the ABS pipe, before finishing with some lap sealant around the bottom edge.
I understand why you and others wouldn't like this repair and I agree this would not be a "best" and permanent fix. However, I do believe it will properly meet my needs. If it doesn't then I will certainly report back on this thread and that knowledge will be very beneficial to anyone else with a similar problem in the future.
