We just had several hours of torrential rain and wind (nearly tropical storm conditions).
The only leak was a very tiny bit (few tablespoons) of water coming in from a skylight, which happens to be over the shower so all the water drops went straight into the gray tank. :-) I removed the interior trim panel and I don't even see any ceiling damage from this tiny leak.
So I guess it's holding up. I'll get up there and apply some more Dicor self-leveling compound around that skylight, and maybe touch up all the other areas with more Dicor.
We have another 24 hours or so of this type of weather so I'll keep going out and checking for more leaks. Hopefully I won't find any.
