Repairing leaking dome on yurt

The dome on the yurt has been leaking for months. I have had to replace the treated plywood ring every year. I'm shocked that the builders of this yurt continue to use this design. They soak the plywood in epoxy but water inevitably makes it way in-between the plies and starts to warp/cup. Eventually the water finds its way inside. This year I'm trying to band aid fix the leak instead of going through the effort of replacing the ring entirely. I used some metal bands bolting the warped wood back flat. Then I applied a thick coat of rubberized tar reinforced with mesh that hangs down past the edge of the plywood. I'm hoping that this buys me a year or two by shedding the water away from the wood preventing it from cupping and directing water into the yurt. Fingers crossed....

A DIY fiberglass part would likely outlast the rest of the yurt.

I like this idea, remake the plywood ring then encapsulate in fiberglass/epoxy. I was also thinking about using a big piece of some aluminum flashing and carefully bending/folding it over the plywood ring.

If you lay the FG on thick enough, you wouldn't even need the flashing, though, it would protect the gel coat from uv, so it isn't a bad idea.

I meant if not fiberglass then aluminum. Fiberglass alone would definitely last long enough. I just don't prefer working with drippy stuff. I make a huge mess. Much safer for me to work with solid materials lol

Ah.

Do you need the thickness of the plywood? If not, just use 1/8 aluminum got the ring and use a good two part epoxy to affix it to the dome. You can cut a ring with a jig saw. (I'd recommend clamping it to wood as a backer to not bend it much.)
