ROOF EXTENSIONS

Roof extensions are continuations of the roof beyond the planes of the sidewall or end wall of a building. The primary purpose of roof extensions, whether at the sidewall or end wall, is to provide additional weather protection to the walls. They can also add aesthetic beauty to the overall physical appearance of a building.

The framing of sidewall roof extensions may consist of built-up members, hot rolled members or cold formed sections that are cantilevered from the building at the sidewalls. Whereas the framing of end wall roof extensions consists mainly of cold formed “Z” sections which are continuous extensions of the end bay purlins and eave struts of the main building.
