Metal Building Roof Extensions
As a matter of standard design, a pre-engineered metal building’s roof does not extend over the walls as is more common with traditional methods of construction. Metal building roof extensions are a commonly requested option when attempting to enhance the appearance of a steel building.
Roof Extensions
Roof extensions can project up to 5′, can be added to any combination of the four building sides, and usually include matching 26GA white soffit panels. Roof extensions on the gable ends of a metal building are referred to as “purlin extensions” and roof extensions on the sidewalls are referred to as “canopy extensions”.
Purlin and canopy extensions can become costly in both high wind load and high snow load environments. For high wind load projects, roof extensions are akin to putting wings on an airplane and the engineering of the building will be modified to account for uplift. For high snow load projects, roof extensions are engineered to support twice the snow load as the main roof.
It is also important to note that purlin and canopy extensions not only add to the cost of the metal building but also result in higher erecting costs as the soffit and trim for the roof extensions will consume more erecting labor.
