What is a roof overhang?

Let’s analyze the process of the formation of overhangs, their purpose and material for their hem.

What is a roof overhang?

The overhang is called a part of the roof structure protruding outside the perimeter of the walls. In fact, the roof covers the walls like a hat hat with its leg, thereby protecting the walls from straight precipitation and from water flowing along the roof. If you make the roof strictly on the dimensions of the masonry, it turns out that all the water with rain and melting snow will drain along the walls, and the rain will generously wash them even in calm weather. Any builder or a person who understands the topic will definitely declare that such a practice is evil for the structure and for a long time it will not last. Therefore, the device of the roof of all types involves the creation of cornices.
