Cantilever Roof Overhangs



A cantilever roof overhang is a structural feature that projects from the side of a building. It differs from a regular roof overhang because the overhang is built into the structure’s design rather than just a part of the roof truss.

Wright, an architect and interior designer was an early pioneer of cantilever roofs. His signature style used cantilevered roofs that extended outwards, supported by steel beams.

How Builders  Construct a Cantilever Roof Overhang

It is important to note that a cantilever is not just an overhang supported by a wall or column. Your contractor integrates the cantilever into the structure of the building. The overhang is an integral part of the structure and not just an add-on. 

When Should You Not Use a Cantilever Roof Overhang

There are some circumstances when you might not want to use a cantilever roof overhang. One is if you live in an area with high winds. The extended structure can act like a sail and catch the wind, putting stress on the building and causing damage.

Cantilevers Create Thermal Bridges

Thermal bridging can  create significant energy losses and the potential to develop condensation and mold. You will need to work with your engineer and builder to design a thermal break if you live in a hot or cold climate.
