Chimney leaking water — Alkmaar, North Holland
Water entering around a chimney is one of the most common — and most damaging — roof leak sources. The leak usually originates from deteriorated flashing (the metal strips where the chimney meets the roof), a cracked chimney crown, damaged mortar joints, or a missing chimney cap. Because chimney leaks send water down hidden paths inside walls, the damage can progress for months before stains appear. A roofer handles flashing and roof-side repairs, while a mason addresses the chimney structure itself. Repair costs range from $200–$500 for reflashing to $1,000–$3,000 for crown and mortar rebuilds.
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.
