A girder truss is  a type of secondary roof support that is most commonly used in the construction  of buildings that have a roof that is irregularly shaped. Its main function is  to support the weight of the roof.
A girder truss is  typically present in L- or T-shaped buildings due to the fact that the roof  changes direction at a sharp angle. Typically, a girder truss is constructed of  wood, although stronger materials, such as steel, are often used. A secondary  function of a girder truss is to provide structural support to both the roof  and the adjoining walls and help buildings withstand hurricanes and other  powerful forces.
