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.
Rockdale County sits in the metro Atlanta hail and wind corridor. Spring storm season here does two kinds of damage, and only one of them is obvious. Straight-line wind lifts shingle tabs, breaks the seal strip underneath, and drops them back down looking untouched — the roof then leaks in the next storm from a spot that shows nothing from the ground. Hail does the other kind, bruising the mat under the granules so the shingle fails months later. Housing stock across Rockdale County skews newer and denser than most of the state, which means a lot of architectural asphalt in the 10-to-20-year band where the seal strip is past its best but the roof is nowhere near replacement.
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.
