Leaking roof vent or flashing — Delft, South Holland
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 Delft
Roofs in Delft range from steep tiled pitches on older buildings to flat membrane roofs; both take a beating from autumn/winter North Sea storm fronts, driving leak and storm-damage callouts.
