Taköverhäng

Taköverhäng, also known as a roof overhang or eave, is the part of a roof that extends beyond the exterior walls of a building. This architectural feature serves multiple practical and aesthetic purposes.

Functionally, the overhang helps protect the building's walls from rain and snow. By extending outward, it directs water away from the foundation, reducing the risk of water damage, erosion, and mold growth. In warmer climates, the overhang can also provide shade for windows and walls, helping to keep the interior cooler and reducing the need for air conditioning. This can contribute to energy efficiency.

Aesthetically, taköverhäng can enhance the visual appeal of a building. They can add depth and character to the roofline, creating a more finished and substantial look. The style and size of the overhang can vary greatly depending on the architectural design of the building, ranging from minimal extensions to very deep, decorative eaves.

The construction of a taköverhäng typically involves extending the rafters or trusses beyond the wall plate. The underside of the overhang is often referred to as the soffit, and the vertical face where the overhang meets the wall is called the fascia. These components are important for both the structural integrity and the appearance of the overhang. In some regions, building codes may specify minimum or maximum overhang lengths for reasons related to weather protection, fire safety, or structural stability.
