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.
Louisville sits in the eastern part of the state where the housing stock is the defining factor. Jefferson County has a wide spread of roof ages, from pre-war homes with original framing to recent subdivisions, and the leak profile differs sharply between them. Older properties leak at chimney flashing and valleys where decades of movement have opened joints that were never designed to flex. Newer ones leak at penetrations — boots, vents and skylights — where installation shortcuts show up five to ten years later. Summer storms bring wind and hail through on the same line that hits central Georgia, so both add storm damage on top.
Louisville has a population of about 2,381, and the housing stock here sets the pattern for what fails first on a roof.
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.
