What product did you try patching it with ? Did you take the corner off and caulk the entire thing then reassemble
A waterproof caulk at first. That initially lasted for a while. I then tried a spray on sealer, like flex seal. That didn’t last very long. Once it got cold out, I think that stuff is useless.
I eventually did take it all apart, clean it, and re-sealed it. Slowly but surely a leak began again. I’ve come to accept the fact that its just always going to drip unless I pay someone to do it right the first time. And the next house isn’t going to be done this way either, I’ll pay someone to do it.
