What is a barge in roof construction?

In roof construction, a barge refers to a horizontal beam that supports rafters. This element plays a crucial role in the structural integrity of the roof as it helps to distribute the load of the rafters, which are the sloped members supporting the roof deck. The barge is typically located at the edge of the roof where it extends outward, providing both stability and a finished appearance to the roofline.

This understanding is significant as it relates to overall roof design and construction practices, ensuring that the roof can adequately withstand environmental factors such as wind and snow loads. By supporting the rafters properly, the barge contributes to the longevity and resilience of the roofing system.
