The Overhang Of A Roof

But are they really necessary.

The overhang of a roof.

Overhangs are common in most house designs providing protection against both wind and rain. The length of the overhang depends primarily on the climate. Roof overhangs at the eaves and rakes protect the walls below from rain and sun. Overhangs on all four sides of barns is common in swiss architecture.

Roof overhangs are the amount that the roof hangs over the top of the siding in residential home construction. That is their functional purpose. An overhanging eave is the edge of a roof protruding outwards beyond the side of the building generally to provide weather protection. They also help to frame windows on upper stories.

Eaves form the overhang to distribute water clear of the walls.
