How to Install a Wooden Overhang

Overhang extensions can be added to buildings, sheds and other structures to offer shelter and protection from sun, rain and snow. The overhang can also add a decorative element to a home and be used as a porch or area for people to gather and relax under. A wooden overhang is durable and can be installed using a few common items purchased from most hardware stores.
