Valley leaks
Where two roof slopes meet
Skylights reach a point where reflashing is not enough — a rotted frame, a failed sealed unit with moisture between the panes, or a unit old enough that compatible flashing is no longer made. Replacement is roof work as much as window work, because the flashing kit and its relationship to the surrounding courses is what keeps water out. A new unit fitted with old or improvised flashing leaks exactly like the one it replaced.
Quitman County is far enough south to take the inland remnants of Gulf and Atlantic hurricane systems, and that is the storm profile that matters here. By the time these systems reach Quitman County the wind has dropped below the headline numbers but is still sustained for hours, which does something different to a roof than a short violent gust — it works shingle tabs loose over an extended period and drives rain horizontally under courses that would shed a normal downpour. The heat and humidity do the rest. Roofs here run hot for most of the year, which ages the shingle and hardens every rubber and sealant component, and the humidity means anything that gets wet inside the roof stays wet.
On some units yes, where the sealed unit is a serviceable part and the frame is sound. On older or sealed-frame models the whole unit is the replacement item.
The courses around the opening have to be lifted and reinstated regardless, so it is worth checking the surrounding area while access is there. On an older roof it is often sensible to do both together.
