Pipe boot and vent leaks
Cracked rubber collars around pipes
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.
Baraboo has a winter long enough and cold enough that ice damming, not storm damage, is the dominant cause of roof leaks. The mechanism is heat loss rather than weather: warm air escaping into the attic melts snow on the upper roof, the meltwater runs down and refreezes over the cold overhang, and the resulting ridge of ice backs water up beneath the shingle courses until it finds a way in. The roof itself is usually in perfect condition. Repeated through a Sauk County winter, freeze-thaw also works every flashing joint progressively looser, and spring brings hail and straight-line wind on top. The reason this matters is that fixing an ice dam leak by working on the shingles does not work — the problem is insulation and ventilation, and that is a different job.
Baraboo has a population of about 12,048, 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.
