Leaking roof vent or flashing — Chicago, Illinois
Leaks around roof vents, pipes, or flashing are one of the most common causes of roof leaks. Flashing — the thin metal strips that seal transitions between the roof and chimneys, vents, or walls — deteriorates over time from UV exposure, thermal cycling, and storms. Even a small gap lets water infiltrate into the attic and down through ceilings. A roofer can remove the old flashing, install new step or counter flashing, reseal vent boots, and verify there's no hidden water damage in the decking below.
Why this is common in Chicago
Chicago's freeze-thaw cycles, heavy snowfall, and ice dam formation are brutal on roofs. Flat roofs on bungalows and two-flats are especially vulnerable. Wind damage from severe storms off Lake Michigan accelerates shingle deterioration.
