Ice dam on roof — Alkmaar, North Holland
Ice dams form along the roof edge when snow melts from the warm upper roof and refreezes at the cold eaves. The trapped water backs up under shingles, causing leaks into attic spaces, walls, and ceilings. Left untreated, ice dams cause extensive water damage, rotting fascia boards, and mold growth. A roofer can safely remove ice dams, install ice-and-water shield membrane, and improve attic ventilation to prevent recurrence.
Why this is common in Alkmaar
The historic center's clay-tile and slate-roof canal houses require specialized restoration expertise. Frequent Atlantic rain and wind accelerate moss growth and tile displacement. Flat-roof extensions on 1970s–1990s residential buildings are approaching end-of-membrane-life and represent a high-volume repair category.
