Dachabläufe

Dachabläufe, also known as roof drains or gutter outlets, are essential components of a building's drainage system. Their primary function is to collect rainwater from the roof surface and safely channel it away from the building's structure. This prevents water accumulation, which can lead to significant damage over time, including structural weakening, mold growth, and damage to the roof membrane itself.

Dachabläufe are typically installed at low points on a flat or low-slope roof, often near parapet walls or other edges where water naturally collects. They are designed to allow water to flow freely while preventing debris such as leaves, twigs, and dirt from entering and blocking the drainage pipes. Many Dachabläufe incorporate a grate or strainer to catch this debris.

The materials used for Dachabläufe vary, but common options include durable plastics like PVC, as well as metals such as aluminum, stainless steel, or copper. The choice of material often depends on the roofing material, climate, and budget. Installation requires careful sealing to ensure a watertight connection with the roof membrane and the downpipe. Regular maintenance, including clearing out any accumulated debris, is crucial for ensuring the efficient operation of the Dachablauf and preventing costly water damage.
