Leaking roof vent or flashing — Barcelona, Catalonia
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.
Waarom dit veel voorkomt in Barcelona
The Eixample's early-1900s buildings feature flat and tile roofs, ornate Modernista cornices, and shared terraces (terrats) that require heritage-aware repair on catalogued buildings. Mediterranean humidity and occasional intense autumn storms drive waterproofing and drainage work, and façade-and-roof interventions on protected blocks need Ajuntament heritage clearance before scaffolding goes up.
