Roof flashing pulling away — Barcelona, Catalonia
Roof flashing is the thin metal strip that seals joints where the roof meets walls, chimneys, dormers, or vents. When it pulls away, lifts, or develops gaps, rainwater bypasses the shingles and runs directly into the roof deck, causing rot, mold, and interior water damage. A roofer removes the old sealant, re-bends or replaces the flashing, re-integrates it with the shingle courses, and applies fresh roofing cement to restore a watertight seal.
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.
