Valley leaks
Where two roof slopes meet
Low-slope roofs fail differently from pitched ones and are diagnosed differently. Water does not run off, it sits, so the failure points are seams, upstands and the flashing where the roof meets a parapet or wall. Ponding that is still present forty-eight hours after rain is the clearest warning — it means the fall is wrong or a drain is blocked, and standing water will find any weakness in a seam eventually. Patching a flat roof without addressing why water is sitting there is temporary by definition.
Franklin County 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.
Water that clears within forty-eight hours is normal. Water still sitting after that is adding load, accelerating membrane breakdown and will find any seam weakness. It usually means a blocked outlet or a fall that was never right.
Isolated seam or puncture failures patch perfectly well when the membrane is otherwise sound. Once there are multiple failures across the field, or the membrane has gone brittle, patching stops being economic.
