Valley leaks
Where two roof slopes meet
A chimney can let water in without the roof being involved at all. A cracked crown, a missing cap, spalled brick or eroded mortar joints all admit water into the stack, where it travels down and appears inside looking exactly like a roof leak. Because the symptom is identical, chimneys are a common source of leaks that have been repaired at roof level more than once without success.
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.
Both present almost identically. Flashing leaks usually show at ceiling level where the stack passes through; masonry leaks often show lower, on the breast itself, and worsen with wind-driven rain from a particular direction. Checking both before working on either saves repeating the job.
More so, arguably. An open flue on a disused stack takes rain straight into the structure with nothing drawing it back out, so the masonry stays wet and deteriorates faster than one in use.
