Underlayment replacement
The secondary barrier under the covering
Skylights leak at the flashing kit or the perimeter seal far more often than through the glass itself. The unit sits proud of the roof plane and interrupts the water path, so everything depends on how the flashing was stepped into the surrounding courses. Water showing at the corners of the opening inside is the classic sign. Condensation on the inside of the pane is a different problem entirely — that is ventilation, not a leak, and sealing the outside will not touch it.
Lavonia sits in the Blue Ridge foothills, which puts it in a different roofing climate from most of Georgia. The mountains get real freeze-thaw cycling: water works into a hairline gap in flashing during the day, freezes overnight, expands, and opens the gap a little wider. Repeat that through a Franklin County winter and a joint that was watertight in October is leaking by March. Ice at the eaves is the other one — meltwater running down a warm roof refreezes over the cold overhang and backs up under the shingle course, which is how water ends up inside a roof with no visible damage at all. Steep pitches shed snow well but make access harder, and older stock here runs to standing-seam and pressed metal, which fails at the fastener rather than the panel.
Lavonia has a population of about 2,143, and the housing stock here sets the pattern for what fails first on a roof.
No. Moisture on the room-side face of the glass is warm damp air meeting a cold surface, and it is a ventilation problem. Moisture trapped between the panes means the sealed unit has failed and the glazing needs replacing. Neither is fixed by working on the roof.
If the unit itself is sound it can be reflashed, which is far cheaper. Replacement makes sense when the frame has rotted, the seal between panes has gone, or the unit is old enough that matching flashing is no longer available.
