In that case I'd vent it properly and make sure the whirlybirds are actually functioning(they often dont). Also you'll want to make certain the rest of the sea can is water tight(as best you can) if it isn't those roof vents won't be enough to keep excess moisture out.

Today was angle grinding off the existing roofing asphalt. That stuff is a mess, but fortunately got it all off.

I picked up a 12” x 12” gable louver to put in the rear side of the container (where it can catch a draft). The one I picked up has a mesh grate in the rear of it, but I’m going to find a way to add foam or something to filter the air intake. (Tape an air filter around it?)

I also picked up a replacement 12” whirlybird because the previous one wasn’t installed correctly (and the whole assembly was busted, including the bearings). Get to take that on tomorrow!

Also picked up some tek roofing screws, and silicon roofing sealant. (Tho another comment suggested automotive sealant?)

Thanks for the help!
