Sky Light condensation

This is a strange one, I had our sky light in for years, no issues or leaks, even after our new roof, it was fine, now that we put in a remote shade, I see a water line coming down from the sky light, is it possible since this SL is in a bathroom, that if we have the shade closed, moisture can build up on the glass, and run down the wall, its not enough to even drip on the floor, just a small water line mark I see on the wall under the light? weird? can't figure this out.

It is possible.

The moisture was there before, just didn't condense until you blocked the drying air flow with the shade.
Similar to a basement slab that was "dry" until a floor covering was installed that molded. Took away the drying air movement.

Clean the dryer screen in HOT water if using fabric softener sheets. They leave a residue that impedes air-flow, costing you money. Clean the ducting in the last six months? 17,000 dryer fires annually!
