Roof flashing pulling away — Leiden, South Holland
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.
Why this is common in Leiden
Roofs in Leiden 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.
