dakgoot

A dakgoot is a rain gutter installed along the eaves of a pitched roof. The dakgoot collects rainwater that runs off the roof and directs it to a downspout, preventing water from running down the walls and pooling near the foundation. It is a standard element of building drainage in Dutch-speaking regions and can be visible on the exterior or integrated behind the fascia.

Common materials for dakgoten include zinc, copper, aluminum, steel, and plastic (PVC). They come in semicircular or rectangular cross-sections and are formed into sections joined by seams or mechanical connectors. The gutter is fixed to the roof edge with brackets and is connected to downpipes that discharge water away from the structure.

Proper installation requires a slight slope to maintain flow, typically a fall of a few millimeters per meter. Joints are sealed to prevent leaks, and expansion joints may be used for long runs. Some systems include leaf guards to reduce blockages.

Maintenance involves regular cleaning to remove leaves and debris, inspection for corrosion or cracks, and checking for sagging or leaks at joints. Ice formation can damage gutters in cold climates, and blockages can cause water backing up into the roof or walls. Repairs may involve resealing, re-securing brackets, or replacing sections.
