I have never ever seen a skylight that is actually flush with the roof surface. Does anybody have any information on something like this? I would assume the edge of the roofing should be fully secured and sealed with caulking or sealant??? which this is not.
if anybody has any further knowledge of these I would greatly appreciate it.
I’d write it up for poor/improper installation. The problem with that installation is poor drainage and water retention. Snow and water will just sit there and wreak havoc with the surrounding roof shingles (flashing?). Let a roofer handle it.
