Hmmm. I thought those two-panel skylights, like mine, were sealed together. But you say you removed the inner one Gil? Mine has condensate between them but I can't find even the slightest hint of a crack, scratch, or bad roof seal, so it's been perplexing. I was going to have BCS replace it this spring, but if the two panels aren't laminated together, perhaps I need to remove the inside molded trim and check if the water is actually humid air seeping in from the inside rather than from rain?
